The pagecreate event is triggered on a page when it is initialized, right after initialization occurs. Most of jQuery Mobile's official widgets auto-initialize themselves based on this event, and you can set up your code to do the same.
-$( document ).delegate( "pagecreate", "#aboutPage", function() {
+$( document ).delegate("#aboutPage", "pagecreate", function() {
alert('A page with an ID of "aboutPage" was just created by jQuery Mobile!');
});
If you'd like to manipulate a page's contents before the pagecreate event fires and widgets are auto-initialized, you can instead bind to the pagebeforecreate event:
-$( document ).delegate( "pagebeforecreate", "#aboutPage", function() {
+$( document ).delegate("#aboutPage", "pagebeforecreate", function() {
alert('A page with an ID of "aboutPage" is about to be created by jQuery Mobile!');
});
