What is the correct way (to this date) to use JQuery Mobile and Phonegap together?

Both frameworks need to load before they can be used. How can I be sure that both are loaded before I can use them?

To build on @Jeffrey's answer, I found a much cleaner way which hides the HTML markup until JQM has finished processing the page and renders the first Page element, since I've noticed that 1/2 second flicker of bare markup before JQM renders.

You only need to hide all the markup with css...PageShow() by JQM will toggle the visibility for you. 




//snip
<style type="text/css">
.hide {
  display:none;
}
</style>

//snip - now the markup notice the hide class
<div id="page1" data-role="page" class="hide">
     //all your regular JQM / html form markup
</div>

//snip -- down to the end of /body
<script src="cordova-2.2.0.js"></script>
<script src="js/jquery-1.8.2.min.js"></script>
<script>
   document.addEventListener(
     'deviceready',
      function () {
         $(document).one("mobileinit", function () {
         //any JQM init methods

       });
      $.getScript('js/jquery.mobile-1.2.0.min.js');
   },
   false);
</script>

You can use deferred feature of JQuery.

var deviceReadyDeferred = $.Deferred();
var jqmReadyDeferred = $.Deferred();

document.addEventListener("deviceReady", deviceReady, false);

function deviceReady() {
  deviceReadyDeferred.resolve();
}

$(document).one("mobileinit", function () {
  jqmReadyDeferred.resolve();
});

$.when(deviceReadyDeferred, jqmReadyDeferred).then(doWhenBothFrameworksLoaded);

function doWhenBothFrameworksLoaded() {
  // TBD
}

Loading of PhoneGap is slightly different than loading of jQuery. jQuery works more as a utility library so you include that and it is available for use immediately. On the other hand PhoneGap requires support from native code for proper initialization so it is not ready to use soon after included in the page.

Phonegap suggests to register and wait for deviceready event executing any native specific code.

<!DOCTYPE html>
<html>
  <head>
    <title>PhoneGap Example</title>

    <script type="text/javascript" charset="utf-8" src="lib/jquery.min.js"></script>
    <script type="text/javascript">
        // jquery code here
    </script>
    <script type="text/javascript" charset="utf-8" src="lib/android/cordova-1.7.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    function onLoad(){
        document.addEventListener("deviceready", onDeviceReady, false);
    }

    // Cordova is ready
    function onDeviceReady() {
        // write code related to phonegap here
    }
    </script>
  </head>
  <body onload="onLoad()">
    <h1>Phonegap Example</h1>
  </body>
</html>
