ADF Mobile with JQuery Mobile

ADF Mobile and JQuery Mobile

Recently I’ve been looking at JQuery Mobile. I’ve been using JQuery for quite some time now but I was totally unaware of JQuery Mobile. Given my background in JQuery, I thought it should be a snap to create a JQuery app using ADF Mobile.

It turns out that JQuery Mobile is not exactly the same as straight-up JQuery, but it is close. In a short amount of time I was able to extend my basic “Hello World” JQuery app (in a Local HTML feature of my ADF Mobile application) and have it access the contacts on my device also. This means that I can write functionality in JQuery Mobile and still take advantage of the other capabilities that you get with ADF Mobile, like push notifications and security.

To use JQuery Mobile in an ADF Mobile application, you simply add a Local HTML feature to the ADF Mobile project, and then edit the local HTML file to contain your JQuery Mobile code. One caveat here: I recommend that you use the googleapis URLs for JQuery instead of the links directly to the JQuery site. Why? It was because the domain for googleapis is already in the domain whitelist for ADF Mobile by default.

If you really must use the JQuery Mobile scripts from you will need to add to your applications whitelist. You do this in the Security tab of the adfmf-application.xml file as shown next.

Whitelist-ing external javascript sources

I named my Local HTML page mainPage.html and I set its code to be the following:

<!DOCTYPE html>

                //alert('pageshow - contacts');
            $(document).on( 'pagecreate', "#contacts", function(event){

                //alert("about to refresh in pagecreate - contacts");
                try {
                    var theList = $("#contactList").listview();
                    theList.listview('refresh', true);
                } catch(err) {
                  txt="There was an error on this page.\n\n";

            function onContactSuccess(contacts) {
                // Save array for use on the detail page.
                contactArray = contacts;
                // Clear out any previous contents of the #contactList <ul>
                // Add each contact to the contactList
                for(var i = 0; i < contacts.length; i++) {
                    $("#contactList").append('<li><a href="contactDetail.html?id=' + contacts[i].id + '"><h2>' + contacts[i].name.formatted +

It’s pretty simple. The “main” page has a button that will take you to the “contacts“ page. The contacts page shows a list of the contacts on your device. It also provides a filter for that list. The filtering is done on the javascript side of things, not on the call to get the list of contacts, so filtering the results is pretty fast and doesn’t make more than 1 call to the contacts database to get its information.

If you click on a contact the app will show you a detailed view of that contact. Getting this Master-Detail view was pretty simple once I figured it out. The problem I had was passing the specific contact to the detail view. If I kept the contact detail page defined in the mainPage.html, I couldn’t figure out a good way to pass the information. I tried appending the array index to the href (i.e. “#contactDetail?id=1”) but when the href was evaluated as a local target, the query param was truncated.

The solution was to create a second page that handled the contact details. By using a second page the query parameter was not truncated. JQuery Mobile seemed smart enough to just load the content of the contentDetail.html page, but it ignored the javascript I had. Once I moved all of the javascript into the mainPage.html, everything worked fine.

<!DOCTYPE html>
        <title>New Contact Detail</title>
        <!-- Contact Detail page -->
  <div data-role="page" id="contactDetail">

	<div data-role="header" data-add-back-btn="true">
		<h1>Contact Detail</h1>
	</div><!-- /header -->

	<div role="main" class="ui-content">
            <label for="firstName">First Name</label><input type="text" readonly="true" id="firstName" />
            <label for="lastName">Last Name</label><input type="text" readonly="true" id="lastName" />
            <label for="company">Company</label><input type="text" readonly="true" id="company" />
            <label for="note">Note</label><textarea id="note" cols="30" rows="4" readonly="true" ></textarea>
	</div><!-- /content -->

	<div data-role="footer" data-position="fixed">
            <h4>Built with ADF Mobile</h4>
	</div><!-- /footer -->
  </div><!-- /page -->
The contact detail page

There is still one little display bug that I need to figure out though. For some reason the list of contacts does not display nicely until I enter a character or more in the filter bar. My research led me to the listview() method, however, I have not been able to get that to work. I’ve tried several ways of using the operation and place it in various page event locations, but to no avail. If any of you JQuery experts know how to resolve this issue, I’d love to hear from you!
