How to initialize pages in jquery mobile? pageinit not firing
What's the right way to initialize objects on a jquery mobile page? The events docs say to use "pageInit()" with no examples of that function, but give exa开发者_如何学Pythonmples of binding to the "pageinit" method (note case difference). However, I don't see the event firing at all in this simple test page:
<html>
<body>
<script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript" charset="utf-8" src="http://code.jquery.com/mobile/1.0b3/jquery.mobile-1.0b3.min.js"></script>
<div data-role="page" id="myPage">
test
</div>
<script>
$("#myPage").live('pageinit',function() {
alert("This never happens");
});
</script>
</body>
</html>
What am I missing? I should add that if you change pageinit to another event like pagecreate this code works.
---- UPDATE ----
This bug is marked as "closed" in the JQM issue tracker. Apparently opinions differ about whether this is working properly or not.
It started working when I embedded script within page div:
<body>
<div id="indexPage" data-role="page">
<script type="text/javascript">
$("#indexPage").live('pageinit', function() {
// do something here...
});
</script>
</div>
</body>
Used jQuery Mobile 1.0RC1
.live() is deprecated, suggestion is to use .on() in jQuery 1.7+ :
<script type="text/javascript">
$(document).on('pageinit', '#indexPage', function(){
// code
});
</script>
Check the online doc for more information about .on(): http://api.jquery.com/on/
Turns out this is a bug in 1.0b3 that is fixed in the current head. So if you want a fix now, you gotta grab the latest from git. Or wait for the next release.
jQuery(document).live('pageinit',function(event){
centerHeaderDiv();
updateOrientation();
settingsMenu.init();
menu();
hideMenuPopupOnBodyClick();
})
This is working now. Now all page transitions and all JQM AJAX functionality would work along with your defined javascript functions! Enjoy!
pageinit will not fire in case it is on secondary pages ( NOT MAIN page ) if it is written in common <script> tag...
I have such a problem - on secondary pages that are not loaded with 'rel="external"', the code in the common <script> tag is never executed...
really this code is always executed...
<body>
<div id="indexPage" data-role="page">
<script type="text/javascript">
$("#indexPage").live('pageinit', function() {
// do something here...
});
</script>
</div>
</body>
althrough if you made "tabbed interface", using of "pageshow" is better
I had to put the script in the HTML page section which to me is a bug. It is loaded normally in a browser (not via AJAX) and all on a single page including javascript. We're not supposed to have to use document ready.
The easiest way I found to deal with this was to use JQM + Steal. It works like a charm as long as you put:
<script type='text/javascript' src='../steal/steal.js?mypage'></script>
Inside of the data-role='page' div.
Then use AJAX to connect anything that can use the same mypage.js and use an external link (by using the rel="external" tag) to anything that requires a different steal page.

From the jQuery docs:
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live().
Try this:
$('div.page').live('pageinit', function(e) {
console.log("Event Fired");
});
$(document).on("pageinit", "#myPage", function(event) {
alert("This page was just enhanced by jQuery Mobile!");
});
The events don't fire on the initial page, only on pages you load via Ajax. In the above case you can just:
<script>
$(document).ready(function() {
alert("This happens");
});
</script>
