Jquery library not working with sencha touch?

问题

I am currently building an mobile application that is based on Sencha Touch 2. At the moment im just trying out some experiments to see what Sencha is capable too.

And today I got stuck on a thing that really seems strange - I just wanted to try if I could use the jQuery library for my application and use it's additions.

Strangest thing is I can't get any response from when I am making a jquery function.

I've included the jquery library and my script in the index.html file in my sencha directory and I just made a simple stupid test script too see if it works - but I don't get any reaction at all when im trying it out in the browser. I can see that the library and the script is included via firebug.(As you can see my jquery test is just a simple click event that should display a div, but it ain't).

Am I being plain stupid - or what am I missing out here?

Here's my index.html file

<!DOCTYPE HTML>
<html manifest="" lang="en-US">
<head>
<meta charset="UTF-8">
<title>scroller</title>

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>

<script type="text/javascript">

    $(document).ready(function() {

        $("#show_me").click(function () {
            $('#magic').slideDown('slow');
        });

    });

</script>

回答1:

Maybe the element you are clicking on, doesn't have the id 'showme'. This can happen because the button you created has id 'showme' in Sencha, but the actual HTML that gets rendered contains another id.

If this is true (you can check this using FireBug of course), you might want to listen to the 'tap' event on the button instead of using jQuery to bind to the 'click' event. See http://docs.sencha.com/touch/2-0/#!/api/Ext.Button-event-tap for documentation.

It is possible to use jQuery with Sencha, but it's important to keep in mind that components in Sencha aren't a direct representation of elements in the DOM, some components in Sencha consist of several DOM elements when rendered.

Hope this helps
