Tutorial: Developing a PhoneGap Application


In this tutorial, you create a fully functional employee directory application with PhoneGap. You will learn:

  • How to use different local data storage strategies.
  • How to use several PhoneGap APIs such as Geolocation, Contacts, and Camera.
  • How to handle specific mobile problems such as touch events, scrolling, styling, page transitions, etc.
  • How to build an application using a single page architecture and HTML templates.
  • How to build (compile and package) an application for 6 platforms using PhoneGap Build.

To complete this tutorial, all you need is a code editor, a modern browser, and a connection to the Internet. A working knowledge of HTML and JavaScript is assumed, but you don’t need to be a JavaScript guru.

Setting Up

  1. Download the assets for the workshop here.
  2. Unzip the file anywhere on your file system.
  3. If your code editor allows you to “open a directory”, open the phonegap-workshop-master directory.
  4. Follow the instructions below.
Step-by-step solution files are also available here.

Part 1: Choosing a Local Storage Option


Step 1: Explore different persistence mechansisms

Open the following files in phonegap-workshop-master/js/storage, and explore the different persistence stores they define:

  1. memory-store.js (MemoryStore)
  2. ls-store.js (LocalStorageStore)
  3. websql-store.js (WebSqlStore)

Step 2: Test the application with different persistence mechanisms

To change the local persistence mechanism for the application:

  1. In index.html: add a script tag for the corresponding .js file: memory-store.js, ls-store.js, or websql-store.js.
  2. In js/main.js: Instantiate the specific store in the initialize() function of the app object: MemoryStore, LocalStorageStore, or WebSqlStore.
  3. To test the application, open index.html in your browser, or simply double-click index.html on your file system. Type a few characters in the search box to search employees by name. Clicking an employee link doesn’t produce any result at this time.

Part 2: Building with PhoneGap Build


  1. If you don’t already have one, create an account on http://build.phonegap.com.
  2. Click the “new app” button to create a new application on PhoneGap Build.
  3. Either point to a GitHub repository where you push your code for this workshop, or zip up your phonegap-workshop directory and upload it to PhoneGap Build.
  4. Click the Ready to build button.
    The iOS button will immediately turn red because the iOS build requires that you upload your Apple Developer certificate and an application provisioning profile. You can find more information here if you haven’t already signed up for the Apple Developer Program. If you don’t have an iOS device, or if you are not ready to upload your developer certificate, you can skip step 5 and keep running the application in the browser or a non iOS device.
  5. To upload your Apple developer certificate and your application provisioning profile:
    • Click the red iOS button.
    • Select “add a key” in the “No key selected” dropdown.
    • Provide a title for your developer certificate/provisioning profile combination (for example: EmployeeDirectory), select your developer certificate and provisioning profile, enter your developer certificate password, and click “submit key”.
    • Go back to the list of apps. Click the iOS button for your application again. Select your newly added key in the iOS dropdown. The iOS build will start automatically.
  6. When the build process completes, use a QR Code reader app to install the Employee Directory application on your device.

To fine tune your build preferences:

  1. In the phonegap-workshop directory, create a file namedconfig.xml file defined as follows (make the necessary adjustments for id, author, etc.):
    <?xml version="1.0" encoding="UTF-8"?>
    <widget xmlns       = "http://www.w3.org/ns/widgets"
            xmlns:gap   = "http://phonegap.com/ns/1.0"
            id          = "org.coenraets.employeedirectory"
            versionCode = "10"
            version     = "1.1.0">
    
        <name>Employee Directory</name>
    
        <description>
            A simple employee directory application

        <feature name="http://api.phonegap.com/1.0/notification"/>
    
    </widget>
    
  2. If you used the GitHub approach, sync with GitHub and click the Update Code button in PhoneGap Build.
    If you used the zip file approach, zip up your phonegap-workshop directory and upload the new version to PhoneGap Build
There are many other parameters you can specify in config.xml to configure the build process. See the documentation for config.xml here.

Part 3: Using Native Notification


A default webview alert gives away the fact that your application is not native. In this section, we set up the basic infrastructure to display native alerts when the application is running on a device, and fall back to default browser alerts when running in the browser.

  1. In index.html, add the following script tag (as the first script tag at the bottom of the body):
    <script src="phonegap.js"></script>
    

    This instructs PhoneGap Build to inject a platform specific version of phonegap.js at build time. In other words, phonegaps.js doesn’t need to be (and shouldn’t be) present in your project folder.

  2. In main.js, define a function named showAlert() inside the app object. If navigator.notification is available, use its alert() function. Otherwise, use the default browser alert() function.
    showAlert: function (message, title) {
        if (navigator.notification) {
            navigator.notification.alert(message, null, title, 'OK');
        } else {
            alert(title ? (title + ": " + message) : message);
        }
    },
    
  3. Test the notification logic by displaying a message when the application store has been initialized: Pass an anonymous callback function as an argument to the constructor of the persistence store (the store will call this function after it has successfully initialized). In the anonymous function, invoke the showAlert() function.
    initialize: function() {
        var self = this;
        this.store = new MemoryStore(function() {
            self.showAlert('Store Initialized', 'Info');
        });
        $('.search-key').on('keyup', $.proxy(this.findByName, this));
    }
    
  4. Test the application: When you run the application in the browser, you should see a standard browser alert. When you run the application on your device, you should see a native alert.

Part 4: Setting Up a Single Page Application


A single page application is a web application that lives within a single HTML page. The “views” of the application are injected into- and removed from the DOM as needed as the user navigates through the app. A single page application architecture is particularly well suited for mobile apps:

  • The absence of continual page refreshes provides a more fluid / closer to native experience.
  • The UI is entirely created at the client-side with no dependency on a server to create the UI, making it an ideal architecture for applications that work offline.

In this section, we set up the basic infrastructure to turn Employee Directory into a single page application.

  1. In index.html: remove the HTML markup inside the body tag (with the exception of the script tags).
  2. In main.js, define a function named renderHomeView() inside the app object. Implement the function to programmatically add the Home View markup to the body element.
    renderHomeView: function() {
        var html =
                "<div class='header'><h1>Home</h1></div>" +
                "<div class='search-view'>" +
                "<input class='search-key'/>" +
                "<ul class='employee-list'></ul>" +
                "</div>"
        $('body').html(html);
        $('.search-key').on('keyup', $.proxy(this.findByName, this));
    },
    
  3. Modify the initialize() function of the app object. In the anonymous callback function of the store constructor, call the renderHomeView() function to programmatically display the Home View.
    initialize: function() {
        var self = this;
        this.store = new MemoryStore(function() {
            self.renderHomeView();
        });
    }
    

Part 5: Using Handlebar Templates


Writing HTML fragments in JavaScript and programmatically inserting them into the DOM is tedious. It makes your application harder to write and harder to maintain. HTML templates address this issue by decoupling the UI definition (HTML markup) from your code. There are a number of great HTML template solutions: Mustache.js, Handlebar.js, and Underscore.js to name a few.

In this section, we create two templates to streamline the code of the Employee Directory application. We use Handlebar.js but the smae result can be achieved using the other HTML template solutions.

Modify index.html as follows:

  1. Add a script tag to include the handlebar.js library:
    <script src="lib/handlebars.js"></script>
    
  2. Create an HTML template to render the Home View. Add this script tag as the first child of the body tag:
    <script id="home-tpl" type="text/x-handlebars-template">
        <div class='header'><h1>Home</h1></div>
        <div class='search-bar'><input class='search-key' type="text"/></div>
        <ul class='employee-list'></ul>
    </script>
    
  3. Create an HTML template to render the employee list items. Add this script tag immediately after the previous one:
    <script id="employee-li-tpl" type="text/x-handlebars-template">
        {{#.}}
        <li><a href="#employees/{{this.id}}">{{this.firstName}} {{this.lastName}}<br/>{{this.title}}</a></li>
        {{/.}}
    </script>
    

Modify main.js as follows:

  1. In the initialize() function of the app object, add the code to compile the two templates defined above:
    this.homeTpl = Handlebars.compile($("#home-tpl").html());
    this.employeeLiTpl = Handlebars.compile($("#employee-li-tpl").html());
    
  2. Modify renderHomeView() to use the homeTpl template instead of the inline HTML:
    renderHomeView: function() {
        $('body').html(this.homeTpl());
        $('.search-key').on('keyup', $.proxy(this.findByName, this));
    },
    
  3. Modify findByName() to use the employeeLiTpl template instead of the inline HTML:
    findByName: function() {
        var self = this;
        this.store.findByName($('.search-key').val(), function(employees) {
            $('.employee-list').html(self.employeeLiTpl(employees));
        });
    },
    
  4. Test the application.

Part 6: Creating a View Class


It’s time to provide our application with some structure. If we keep adding all the core functions of the application to the app object, it will very quickly grow out of control. In this section we create a HomeView object that encapsulates the logic to create and render the Home view.

Step 1: Create the HomeView Class

  1. Create a file called HomeView.js in the js directory, and define a HomeView class implemented as follows:
    var HomeView = function(store) {
    
    
    }
    
  2. Add the two templates as static members of HomeView.
    var HomeView = function(store) {
    
    
    }
    
    HomeView.template = Handlebars.compile($("#home-tpl").html());
    HomeView.liTemplate = Handlebars.compile($("#employee-li-tpl").html());
    
  3. Define an initialize() function inside the HomeView class. Define a div wrapper for the view. The div wrapper is used to attach the view-related events. Invoke the initialize() function inside the HomeView constructor function.
    var HomeView = function(store) {
    
        this.initialize = function() {
            // Define a div wrapper for the view. The div wrapper is used to attach events.
            this.el = $('<div/>');
            this.el.on('keyup', '.search-key', this.findByName);
        };
    
        this.initialize();
    
    }
    
    HomeView.template = Handlebars.compile($("#home-tpl").html());
    HomeView.liTemplate = Handlebars.compile($("#employee-li-tpl").html());
    
  4. Move the renderHomeView() function from the app object to the HomeView class. To keep the view reusable, attach the html to the div wrapper (this.el) instead of the document body. Because the function is now encapsulated in the HomeView class, you can also rename it from renderHomeView() to just render().
    this.render = function() {
        this.el.html(HomeView.template());
        return this;
    };
    
  5. Move the findByName() function from the app object to the HomeView class.
    this.findByName = function() {
        store.findByName($('.search-key').val(), function(employees) {
            $('.employee-list').html(HomeView.liTemplate(employees));
        });
    };
    

Step 2: Using the HomeView class

  1. In index.html, add a script tag to include HomeView.js (just before the script tag for main.js):
    <script src="js/HomeView.js"></script>
    
  2. Remove the renderHomeView() function from the app object.
  3. Remove the findByName() function from the app object.
  4. Modify the initialize function() to display the Home View using the HomeView class:
    initialize: function() {
        var self = this;
        this.store = new MemoryStore(function() {
            $('body').html(new HomeView(self.store).render().el);
        });
    }
    

Part 7: Adding Styles and Touch-Based Scrolling


Step 1: Style the Application

  1. Add the Source Sans Pro font definition to the head of index.html
    <script src="css/source-sans-pro.js"></script>
    

    Source Sans Pro is part of the free Adobe Edge Web Fonts.

  2. Add styles.css to the head of index.html
    <link href="css/styles.css" rel="stylesheet">
    
  3. In index.html, modify the home-tpl template: change the search-key input type from text to search.
  4. Test the application. Specifically, test the list behavior when the list is bigger than the browser window (or the screen)

Step 2: Native Scrolling Approach

  1. Modify the home-tpl template in index.html. Add a div wrapper with a scroll class around the ul element with a scroll:
    <script id="home-tpl" type="text/x-handlebars-template">
        <div class='header'><h1>Home</h1></div>
        <div class='search-bar'><input class='search-key' type="search"/></div>
        <div class="scroll"><ul class='employee-list'></ul></div>
    </script>
    
  2. Add the following class definition to css/styles.css:
    .scroll {
        overflow: auto;
        -webkit-overflow-scrolling: touch;
        position: absolute;
        top: 84px;
        bottom: 0px;
        left: 0px;
        right: 0px;
    }
    
If the platforms you target support touch-based scrolling of fixed regions, this approach is all you need (you can skip step 3 below). If not, you’ll need to implement a programmatic approach, typically with the help of a library such as iScroll.

Step 3: iScroll Approach

  1. Add a script tag to include the iscroll.js library:
    <script src="lib/iscroll.js"></script>
    
  2. In HomeView.js, modify the findByName() function: Instantiate an iScroll object to scroll the list of employees returned. If the iScroll object already exists (), simply refresh it to adapt it to the new size of the list.
    this.findByName = function() {
        store.findByName($('.search-key').val(), function(employees) {
            $('.employee-list').html(HomeView.liTemplate(employees));
            if (self.iscroll) {
                console.log('Refresh iScroll');
                self.iscroll.refresh();
            } else {
                console.log('New iScroll');
                self.iscroll = new iScroll($('.scroll', self.el)[0], {hScrollbar: false, vScrollbar: false });
            }
        });
    };
    
More information on iScroll is available here.

Part 8: Highlighting Tapped or Clicked UI Elements


  1. In styles.css, add a tappable-active class definition for tapped or clicked list item links. The class simply highlights the item with a blue background:
    li>a.tappable-active {
        color: #fff;
        background-color: #4286f5;
    }
    
  2. In main.js, define a registerEvents() function inside the app object. Add a the tappable_active class to the selected (tapped or clicked) list item:
    registerEvents: function() {
        var self = this;
        // Check of browser supports touch events...
        if (document.documentElement.hasOwnProperty('ontouchstart')) {
            // ... if yes: register touch event listener to change the "selected" state of the item
            $('body').on('touchstart', 'a', function(event) {
                $(event.target).addClass('tappable-active');
            });
            $('body').on('touchend', 'a', function(event) {
                $(event.target).removeClass('tappable-active');
            });
        } else {
            // ... if not: register mouse events instead
            $('body').on('mousedown', 'a', function(event) {
                $(event.target).addClass('tappable-active');
            });
            $('body').on('mouseup', 'a', function(event) {
                $(event.target).removeClass('tappable-active');
            });
        }
    },
    
  3. Invoke the registerEvents() function from within the app object’s initialize() function.
  4. Test the application.

Part 9: View Routing


In this section, we add an employee details view. Since the application now has more than one view, we also add a simple view routing mechanism that uses the hash tag to determine whether to display the home view or the details view for a specific employee.

Step 1: Create the employee template

Open index.html and add a template to render a detailed employee view:

<script id="employee-tpl" type="text/x-handlebars-template">
    <div class='header'><a href='#' class="button header-button header-button-left">Back</a><h1>Details</h1></div>
    <div class='details'>
        <img class='employee-image' src='img/{{firstName}}_{{lastName}}.jpg' />
        <h1>{{firstName}} {{lastName}}</h1>
        <h2>{{title}}</h2>
        <span class="location"></span>
        <ul>
            <li><a href="tel:{{officePhone}}">Call Office<br/>{{officePhone}}</a></li>
            <li><a href="tel:{{cellPhone}}">Call Cell<br/>{{cellPhone}}</a></li>
            <li><a href="sms:{{cellPhone}}">SMS<br/>{{cellPhone}}</a></li>
        </ul>
    </div>
</script>

Step 2: Create the EmployeeView class

  1. Create a file called EmployeeView.js in the js directory, and define an EmployeeView class implemented as follows:
    var EmployeeView = function() {
    
    
    }
    
  2. Add the template as a static member of EmployeeView.
    var EmployeeView = function() {
    
    
    }
    
    EmployeeView.template = Handlebars.compile($("#employee-tpl").html());
    
  3. Define an initialize() function inside the HomeView class. Define a div wrapper for the view. The div wrapper is used to attach the view related events. Invoke the initialize() function inside the HomeView constructor function.
    var EmployeeView = function(employee) {
    
        this.initialize = function() {
            this.el = $('<div/>');
        };
    
        this.initialize();
    
     }
    
    EmployeeView.template = Handlebars.compile($("#employee-tpl").html());
    
  4. Define a render() function implemented as follows:
    this.render = function() {
        this.el.html(EmployeeView.template(employee));
        return this;
    };
    
  5. In index.html, add a script tag to include EmployeeView.js (just before the script tag for main.js):
    <script src="js/EmployeeView.js"></script>
    

Step 3: Implement View Routing

  1. In the app’s initialize() function, define a regular expression that matches employee details urls.
    this.detailsURL = /^#employees\/(\d{1,})/;
    
  2. In the app’s registerEvents() function, add an event listener to listen to URL hash tag changes:
    $(window).on('hashchange', $.proxy(this.route, this));
    
  3. In the app object, define a route() function to route requests to the appropriate view:
    • If there is no hash tag in the URL: display the HomeView
    • If there is a has tag matching the pattern for an employee details URL: display an EmployeeView for the specified employee.
    route: function() {
        var hash = window.location.hash;
        if (!hash) {
            $('body').html(new HomeView(this.store).render().el);
            return;
        }
        var match = hash.match(app.detailsURL);
        if (match) {
            this.store.findById(Number(match[1]), function(employee) {
                $('body').html(new EmployeeView(employee).render().el);
            });
        }
    }
    
  4. Modify the initialize() function to call the route() function:
    initialize: function() {
        var self = this;
        this.detailsURL = /^#employees\/(\d{1,})/;
        this.registerEvents();
        this.store = new MemoryStore(function() {
            self.route();
        });
    }
    
  5. Test the application.

Part 10: Using the Location API


In this section, we add the ability to tag an employee with his/her location information. In this sample application, we display the raw information (longitude/latitude) in the employee view. In a real-life application, we would typically save the location in the database as part of the employee information and show it on a map.

The code below works when running the application as a PhoneGap app on your device. It should also work in Chrome on the desktop when the page is served with the http:// protocol, and in Firefox, regardless of the protocol (http:// or file://).
  1. In index.html, add the following list item to the employee-tpl template:
    <li><a href="#" class="add-location-btn">Add Location</a></li>
    
  2. In the initialize() function of EmployeeView, register an event listener for the click event of the Add Location list item:
    this.el.on('click', '.add-location-btn', this.addLocation);
    
  3. In EmployeeView, define the addLocation event handler as follows:
    this.addLocation = function(event) {
        event.preventDefault();
        console.log('addLocation');
        navigator.geolocation.getCurrentPosition(
            function(position) {
                $('.location', this.el).html(position.coords.latitude + ',' + position.coords.longitude);
            },
            function() {
                alert('Error getting location');
            });
        return false;
    };
    
  4. Test the Application

Part 11: Using the Contacts API


In this section, we use the PhoneGap Contacts API to provide the user with the ability to add an employee to the device’s contact list.

The code below only works when running the application on your device as a PhoneGap app. In other words, you can’t test it in a browser on the desktop.
  1. In index.html, add the following list item to the employee template:
    <li><a href="#" class="add-contact-btn">Add to Contacts</a></li>
    
  2. In the initialize() function of EmployeeView, register an event listener for the click event of the Add to Contacts list item:
    this.el.on('click', '.add-contact-btn', this.addToContacts);
    
  3. In EmployeeView, define the addToContacts event handler as follows:
    this.addToContacts = function(event) {
        event.preventDefault();
        console.log('addToContacts');
        if (!navigator.contacts) {
            app.showAlert("Contacts API not supported", "Error");
            return;
        }
        var contact = navigator.contacts.create();
        contact.name = {givenName: employee.firstName, familyName: employee.lastName};
        var phoneNumbers = [];
        phoneNumbers[0] = new ContactField('work', employee.officePhone, false);
        phoneNumbers[1] = new ContactField('mobile', employee.cellPhone, true); // preferred number
        contact.phoneNumbers = phoneNumbers;
        contact.save();
        return false;
    };
    
  4. Test the Application

Part 12: Using the Camera API


In this section, we use the PhoneGap Camera API to provide the user with the ability to take a picture of an employee, and use that picture as the employee’s picture in the application. We do not persist that picture in this sample application.

The code below only works when running the application on your device as a PhoneGap app. In other words, you can’t test it in a browser on the desktop.
  1. In index.html, add the following list item to the employee template:
    <li><a href="#" class="change-pic-btn">Change Picture</a></li>
    
  2. In the initialize() function of EmployeeView, register an event listener for the click event of the Change Picture list item:
    this.el.on('click', '.change-pic-btn', this.changePicture);
    
  3. In EmployeeView, define the changePicture event handler as follows:
    this.changePicture = function(event) {
        event.preventDefault();
        if (!navigator.camera) {
            app.showAlert("Camera API not supported", "Error");
            return;
        }
        var options =   {   quality: 50,
                            destinationType: Camera.DestinationType.DATA_URL,
                            sourceType: 1,      // 0:Photo Library, 1=Camera, 2=Saved Photo Album
                            encodingType: 0     // 0=JPG 1=PNG
                        };
    
        navigator.camera.getPicture(
            function(imageData) {
                $('.employee-image', this.el).attr('src', "data:image/jpeg;base64," + imageData);
            },
            function() {
                app.showAlert('Error taking picture', 'Error');
            },
            options);
    
        return false;
    };
    
  4. Test the Application

Part 13: Sliding Pages with CSS Transitions


  1. Add the following classes to styles.css:
    .page {
        position: absolute;
        width: 100%;
        height: 100%;
        -webkit-transform:translate3d(0,0,0);
    }
    
    .stage-center {
        top: 0;
        left: 0;
    }
    
    .stage-left {
        left: -100%;
    }
    
    .stage-right {
        left: 100%;
    }
    
    .transition {
        -moz-transition-duration: .375s;
        -webkit-transition-duration: .375s;
        -o-transition-duration: .375s;
    }
    
  2. Inside the app object, define a slidePage() function implemented as follows:
    slidePage: function(page) {
    
        var currentPageDest,
            self = this;
    
        // If there is no current page (app just started) -> No transition: Position new page in the view port
        if (!this.currentPage) {
            $(page.el).attr('class', 'page stage-center');
            $('body').append(page.el);
            this.currentPage = page;
            return;
        }
    
        // Cleaning up: remove old pages that were moved out of the viewport
        $('.stage-right, .stage-left').not('.homePage').remove();
    
        if (page === app.homePage) {
            // Always apply a Back transition (slide from left) when we go back to the search page
            $(page.el).attr('class', 'page stage-left');
            currentPageDest = "stage-right";
        } else {
            // Forward transition (slide from right)
            $(page.el).attr('class', 'page stage-right');
            currentPageDest = "stage-left";
        }
    
        $('body').append(page.el);
    
        // Wait until the new page has been added to the DOM...
        setTimeout(function() {
            // Slide out the current page: If new page slides from the right -> slide current page to the left, and vice versa
            $(self.currentPage.el).attr('class', 'page transition ' + currentPageDest);
            // Slide in the new page
            $(page.el).attr('class', 'page stage-center transition');
            self.currentPage = page;
        });
    
    },
    
  3. Modify the route() function as follows:
    route: function() {
        var self = this;
        var hash = window.location.hash;
        if (!hash) {
            if (this.homePage) {
                this.slidePage(this.homePage);
            } else {
                this.homePage = new HomeView(this.store).render();
                this.slidePage(this.homePage);
            }
            return;
        }
        var match = hash.match(this.detailsURL);
        if (match) {
            this.store.findById(Number(match[1]), function(employee) {
                self.slidePage(new EmployeeView(employee).render());
            });
        }
    },

    excellent tutorial – best I have seen on creating a good phonegap application architecture

    I haven’t made it all the way through yet but I have found a couple of items that may be of use to others:

    1) Step #4 is missing ending “;” for html var declaration statement – this renders in Chrome desktop browser but not on Android

    2) Step #5.1 tag needs to be placed before the app.js tag (maybe obvious but..)

    also I should mention that I am using PhoneGap 2.2 in Eclipse development environment

    again thanks for the tutorial and architecture example!

  • Sandro

    I have the same issue. Anyone can help us? Thanks!

  • Vladimir

    This is great tutorial, i had pleasure reading and following. There is some code which didn’t work for me, like calling methods within event handlers. So I had to wrap them within anonymous functions and also give them context. For example this event handler this.el.on(‘keyup’, ‘.search-key’, this.findByName); had to be written llike var that = this; this.el.on(‘keyup’, ‘.search-key’, function(){that.findByName();});

    My question is there a particular name for this pattern in JavaScript ? It reminds me some of BackboneJS structuring. Were you inspired by it?

    It would be also great to see some ajax layers and how would that fit into a whole thing.

    Awesome tutorial once again, thanks!

    • Jim O’Keefe

      I had the same experience. Original code caused an error within jQuery. Vlad’s code worked.

    • Jim O’Keefe

      Similarly in step 11.2 this is what worked for me:

      this.el.on(‘click’, ‘.add-location-btn’, function(){that.addLocation(event);});

      notice in particular that the event needed to be passed along to the addLocation function.

      • Jim O’Keefe

        that should be section 10.2 – Using the Location API

    • Anna

      Thanks for this fix!

    • Thought this is toooo late but this just to give you more information on JavaScript objects. The code is perfectly written without any single error your context issue is invalid.

      see in JavaScript objects you have to define the property before its required. Like in this case the issue is not of context what all you have to do is do define the initialize function at the end of the object. So no hacks/tricks required to that.

      JavaScript Objects behavior is not similar to other programming languages, you have to define first what ever you want and use it after that. JavaScript works in a single thread environment.

      Thanks

    • MuddJeff

      Check that you have the ’employee’ in Part 9, step 2.
      var EmployeeView = function(employee) { … }

      It’s there in step 2.3, but not in step 2.1 – 2.2

    Wow, native development?? Hardly, this is web development without the benefit of serving UI remotely. Just because it compiles into an “app” doesn’t make it “native”. It’s still depends on a browser, inferior JS engines and JS APIs, and HTML code.

    Hi, very nice tutorial, was a great help for me!
    I have one question, the transitions between pages does some weird shit.
    the moment I click a link, the transitions start, but the content of the first page suddenly jumps down
    the content fades away, but is suddenly 50-100pixels lower before leaving the screen
    transition left or right, it’s the same problem

    Any idea?

      Nevermind, fixed it…
      Other question, anyone here who knows how to work with iScroll? The scrolling works but the content jumps back to the top as soon as I release my finger?

  • cash

    This is a completely useless tutorial

    Getting this crappy technology to work with eclipse is impossible unless you just want to write “hello
    world” .

    Phonegap is a far greater problem and more of a hassle than actually learning android .

    Don’t waste your time with this joke of a “technology” .

    But wait ! They have a solution – give away your idea and thus create a thousand clone apps on Github and they will compile it for you.
    That’s sweet.

  • Nym

    Christophe, I am curious if there is some benefit to replacing all content within the body tag rather than say just the html inside a container div with main content, in turn keeping the header bar in place. Of course this would eliminate the use of the page slide effect as well but that’s not something I really need. A coworker of mine suggested that it may be a performance issue manipulating the DOM but if the entire HTML content of the body tag is being replaced, isn’t that DOM manipulation as well?

  • gary

    One thing that got me confused is that the chapter “Part 7: Adding Styles and Touch-Based Scrolling”
    didn’t really affect the way the page looked, until I replaced

    – $(‘body’).html(new HomeView(self.store).render().el);
    + $(‘body’).append(new HomeView(self.store).render().el);

    (this change is spelled out much later in the last chapter but was not given at part 7 where it changes the entire “look”)

    please address all the comments in this tutorial to make it awesomer :)

    some parts of the code could be cleaned up. e.g:

    if (this.homePage) {
    this.slidePage(this.homePage);
    } else {
    this.homePage = new HomeView(this.store).render();
    this.slidePage(this.homePage);
    }

    could be replaced by
    if (!this.homePage) {
    this.homePage = new HomeView(this.store).render();
    }
    this.slidePage(this.homePage);

    Hi can someone help me understand the search capability of Employee Directory a bit better?

    We would like to use this in our organisation but need to be able to search by the person’s name, by Project (this could be the Department field) to see everyone working on a particular project and by location so we can limit search to only people in a particular office. Are you able to search that way with this app ? or does it only let you search by the person’s name?

    Thanks in advance for any info you can provide.

  • JasonMichael

    I think this code provides an interesting start to a project, but unfortunately, I’m not sure if this is a nuance with jQuery or Firefox or both, but tracking the windows.location.hash and then setting windows.location with this code gave some results that took hours to troubleshoot – especially trying to develop this on a PC and then move the code over to Android – that might also have been an issue. I had to put in a “preventDefault()” to keep control of the mouse/click event in order to prevent a page loading issue. Also, I suspect since the code is using $.proxy, it continues to retain old values and never gets the new hash value after the event – so this required me to put the hash into a separate object, outside of the app object and using that for the regular expression match – otherwise there was no way I was ever going to have the employee details show up.

    The good thing about spending the time to fix this – I got a very close view of how it all works, and am confident I can use this as a start to a personal project. I think I like this better than the backbone.js example, because my particular project is very involved and I think I could develop using this example first, and then streamline it later – but this code still provides an efficient manner to display content in a fast way, and is flexible enough to play around with various features and possibly get a SQLite database working with it.

    Thanks.

    Thanks a lot for this great tutorial, keep it up!

    At the moment I’m working on a app that uses Handlebars templating.
    Right now I’m trying to include any of the popular touch-swipe libraries (swipe.js, photoSwipe.js, swipeshow.js) in one of my Handlebars templates.

    But I’m keep on getting the same error: ReferenceError: Swipe is not defined @ main.js:43

    I do check if my template is properly loaded, and print it’s html to check if it exists in the DOM, and everything seems in place.
    I’m aware that someone has manage to do this before: http://jsfiddle.net/nGULk/

    For the routing, I use your basic routing function where I check for hashchanges

    $(window).on(‘hashchange’, route);

    and then I initialize the swipe object after parsing the current page in the slidePage function:

    I found perfect site for creating apps…Yesterday I ended up on some site called apps-machine.com . I have to share it with you guys. I started creating my own app and after 15 minutes clicking on their control panel(no programming,just clicks) I made app in what user could make effects on their photos,paint photos,play music,play videos,have notepad,chat and stream music. They got literally 1000’s of features on their control panel :D I think this could be a gold mine :P :P And I read something that they have free app development and so on. Aaand you can change everything all the backgrounds,colors,tabs…and you instantly see it on that same page through their simulator..don’t know how they managed to do that but it is super handy…I am super excited at the moment..time to get some apps on apple and play store :D :D

    • Bleepy

      I’m having the exact same problem.

      I’ve tweaked the slide removal code as a temporary fix, its not nice bit will remove the slide after .375 seconds which is the time of the transition in this example.

      Look for:
      $(‘.stage-right, .stage-left’).not(‘.homePage’).remove();

      Replace with:
      setTimeout(function(){
      $(‘.stage-left, .stage-right’).remove();
      }, 375);

      Nasty I know, but it works for me.

        Unfortunately this does not solve the search bar issue mentioned previously in the moments.

    thanks very much for this tutorial but I want to modify the code so that the back button will go back to the previous page instead of going back to the search page. any ideas how can i do that?

  • Janet

    This tutorial doesn’t work on iOS 7!!!

    There is a redirect loop on install and the app never gets fully installed. This seems to be the case with all of the PhoneGap Build apps in iOS 7.

    Anyone found a fix yet?

    • GrandSteph

      Janet,
      I had what I believe was the same issue and solved it in 2 steps. First, the UDID app I used to retrieve the device’s unique ID doesn’t work in iOS7. You have to use itunes (connect the device to your computer, then select the device in itunes and click on serial#, it will reveal the UDID. Then copy and it will copy it to your clipboard).
      Second, I had to redo the provisionning profile to match the correct UDID of the device. It did the trick for me. Hope it helps.

    Hi,

    its somehow frustrating.

    i just zip the solutions (www15) and let it build on phonegap online.
    Then installed it on my device (nexus 5).

    After open the app, everything works (like search, and visiting the profile)
    except all plugins : (

    It says “Contact API is not supported” or
    “Camera API is not supported”.

    I didnt change anything… why doesnt it work :(
    It would be very kind, if someone can help.

    Kind regards.

    • Dan

      Found the issue. You need to add the following to the index.html as the first script include:

      Second, in the config.xml, you will need the following. This will allow the build to know what packages to include. After you upload your zip file, you should see all the plugins that are referenced in the <gap:plugin nodes.

          Hi Dan – I’m brand new to phonegap and apps in general – I’m following this post as it is a great starting point but I cannot get the contact and camera APIs to work no matter what. I’ve followed your post about the cordova.js and the changes to config.xml but still getting seeing “error: Camera API not supported”. My code looks exactly like the post code as is + your changes to index.html and config.xml… any. I’m testing it on a Nexus 5 running Android 5.1 – any suggestions are much appreciated.

    any fascinating article like yours. It’s pretty price enough for me.
    In my opinion, if all webmasters and bloggers made just right content material as you probably did, the internet
    will be a lot more useful than ever before.

  • Great Tutorial, thank you!

  • Have you ever considered publishing an ebook or guest authoring on other blogs?
    I have a blog based upon on the same topics you discuss and
    would love to have you share some stories/information. I know my readers would enjoy your

    I had problems with the camera working ios 7.0.4

    So I removed the namedconfig.xml and replaced it with the config.xml (to work with the newer version photogap).

    Here are the contents of the new config file. Hope it helps.

    Sample Config.xml

  • Fantastic! Thank you Chris!! :)

  • Phonegap is a nice tool, no doubt about it. I have developed various apps with this mobile app development tool whereas now it must need some changes. There are various tools available which provides more features compared to Phonegap. Just look at the features list of Configure.IT,

    http://www.configure.it/features/mobile-app-configuration/

    I have recently made an app with this mobile app development platform, and I found it amazing. Try your hand on it.

  • Amazing tutorial . I began to think to learn more about PhoneGap . hopefully in the future I can be a reliable developer

    Hello, this really helps. However, I’d like to run a function to get all the contents when the app opens.

    I’ve written a function ‘getAll’ and it’s easy enough to attach this to a button “this.el.on(‘click’, ‘#loadall’, this.getAll);”,. but i’d like to load it right away and avoid having to click on the ‘load all’ button.

    Any suggestions for where to call the getAll function?

  • Hey! Many thanks for your tutorial.

    I was wondering what was the cleanest way to add data from remote api to populate this.employee in the memory-store example.

    Could you help me on this?

  • Dennis

    Good tutorials!

    I have a question?how to populate all the data on load?

    Thanks

  • Great tutorials. I’ve learned a lot.
    How come in the websql-store.js you always drop the table and repopulate it? How come you don’t check the version first and not install it if there are no changes?

    I love this tutorial! Thank you for making it! I have gone through it to create the single-page application and am seeking to do two additional things and any help is appreciated:

    1. I wish to show the employee list before any search is executed, to support both searching for a name and browsing the list without requiring a search

    2. Once an employee detail is viewed, how do we restore the employee list that user had filtered to? Currently going back to search view clears any previous search results.

    Cheers.
    Regis

  • Out of the numerous questions that our business development team at Root Info Solutions (RIS) respond to, one, we would like to get answered through this blog. Any guess on that? Well, it’s what are the advantages and disadvantages of the PhoneGap mobile app development.

  • Thanks very much
    Unfortunately when the slider is added, you click an employee and go back, you cant use the search again. This is also broken in your files (part13).
    When you change the code in the main.js, to the following, it will work again (but I think it is not the prettiest solution)
    if (!hash) {
    this.homePage = new HomeView(this.store).render();
    this.slidePage(this.homePage);
    return;
    }

  • ok, better solution
    HomeView.js in the initialize function
    $(document).on(“keyup”, “.search-key”, this.findByName);
    instead of
    this.el.on(‘keyup’, ‘.search-key’, this.findByName);

    my name is carol and I live in USA, My life is back again… After 5years of Broken marriage, my husband left me with kids .I felt like my life was about to end and I almost committed suicide, I was emotionally down for a very long time.Thanks to a spell caster called dr. ovia, which I meet online, On one faithful day, as I was browsing through the internet and I came across a lot of testimonies about this particular spell caster.Some people testified that he brought their Ex boyfriend back, some testified that he restores Womb,Cure Cancer and Herpes Virus and HIV Cure,diabitis hepatitis b, and other sickness, some testified that he can cast a spell to stop divorce and so on. I also come across one particular testimony and it was about a woman called jinni, she testified about how he brought back her Ex lover in less than 2 days and at the end of her testimony she dropped Dr. ovia email address which is, droviaspiritualtemple@gmail.com After reading all these,I decided to give it a try and I contacted him through his via email and explained my problem to him. In just 48 hours, my husband came back to me, and we solved our issues, we are even happier than before Dr. ovia is really a gifted man and I will not stop testifying him because he is a wonderful man and so powerful, If you have a problem and you are looking for a real and genuine spell caster to solve all your problems. contact him on this email: droviaspiritualtemple@gmail.com or call him +2348135858735
