This is the third version of my Employee Directory application. The jQuery Mobile and the Mobile jQuery without jQuery Mobile versions both used JSON services to get data from a remote server. In this version, the application gets data from a local database using the PhoneGap database API. As a result, this version can work offline which is probably what you would expect for this type of application.
You can download the source code here.
The database is created when you start your application. The SQL statements to create and populate the database are in employeelist.js. In a real life application, you would want to abstract that a little more.
