How to find the number of Divs with a certain Class JQuery?
Is there any way to find the number of DIV's dis开发者_如何学Cplayed in the browser with class=.class?
Something like this:
$('.class').Numberofobjects();
*Obviously Numberofobjects is made up.
Thanks!

You want the length property (and make sure to constrain the tag type):
$('div.class').length
.length will give you the list of classes that match
$('.class').length
api here

<head>
<script type="text/javascript" src="jquery-1.6.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
alert($("div.a").length);
});
</script>
</head>
<body>
<input type="button" id="mybutton" value="Click" />
<div class="a">
