Calling a Script when button clicked
In a jquery mobile webpage, I would like to call a script defined within script tags in the HEAD section of the jsp.
<head>
<link rel="stylesheet" type="text/css" href="jquerymobile/jquery.mobile-1.0a1.min.css" />
<script type="text/javascript" src="jquerymobile/jquery-1.4.3.min.js"></script>
<script type="text/javascript" src="jquerymobile/jquery.mobile-1.0a1.min.js"></script>
<script>
$("#button").click( function()
{
alert('button clicked');
}
);
</script>
</head>
<body>
<html:errors/>
<div data-role="page" data-theme='a'>
<div data-role="header">
<h1>jquerymobile</h1>
</div>
<div data-role="content">
<div id="button" data-role="button">Click on button</div>
</div>
</div>
</body>
When the Button is clicked, I want the alert to be shown. But nothing happens when the button is clicked.
Could someone tell me where I am going wrong?
EDIT1:
The following code brings up the alert in Firefox & Opera Desktop Browsers.
$(document).ready(function() {
$("#vbutton").click(function() {
alert("clicked");
});
});
<a id="vbutton" data-role="button">Click Button</a>
Any reason 开发者_JS百科why the same does not work with Opera Mobile & Fennec browsers - where it shows the Error Loading Page dialog??
Your problem is that you are searching for $('#button')
before it exists...
Try wrapping your jQuery code in a $(document).ready(function(){ ... })
or its shorthand alias jQuery(function(){})
The other option is to include your initialization of the click event on the button until AFTER the #button
exists in the DOM. In other words, you can move your <script>
tag to the bottom of the page and it should work.
The problem was due to debug statements like
debugger;
debug.info(....)
which were understood by Firefox/Firebug, but were causing problems in Fennec & Opera Mobile browsers.
