Did you include jquery in your file?

Certainly a correct guess; I explained why in my answer, crediting your comment.

You have to put the reference to the jquery library first is as below.After that put the other references.Order is important here.

<script language="JavaScript" type="text/javascript" src="/js/jquery-1.2.6.min.js"></script>

You can also use @Scripts.Render("~/bundles/jquery) where the path is the path to the file.

One problem your solution having is, where we don't know OP is ASP.net developer or not ? He didn't mention it on his tags.

Abhinav S 28-Sep-13 12:06pm

Fair point. I missed that.

Solution 1

The code, just the syntax you use, looks correct. This error really indicates that you did not include jQuery file. The assumption by vbmike (please see comments to the question) is correct.

I could look like this:

XML

<html>
<head>
    <title>...</title>
    <script type="text/javascript" src="scripts/jquery-1.10.2.min.js"></script>
</head>
<body>

<!-- your page content goes here, with the JavaScript code like the one you show -->

</body>
</html>

And you need to have the jQuery file itself in appropriate place, or a Web link to it, of one or another version. This is where you can download the latest one: http://jquery.com/download/[^].
