And here's another great JQuery feature. If you want to include content from another html page you can use JQuery to drag it in.
Here's a sample page with a button that pulls in and uses text from a second HTML page.
<html>
<head>
<script src="js/jquery-mobile/jquery-1.9.1.min.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
function a() {
$('#contentFromOtherPage').load('test2.html #iphone');
}
</script>
</head>
<body>
<div id="contentFromOtherPage">
this text will be replaced
</div>
<button onclick= "javascript:a();">click</button>
</html>
... and here's the second page where the content comes from
<html>
<head></head>
<body>
<div id="iphone">
this is iphone content
</div>
<div id="android">
this is android content
</div>
</body>
</html>
