A good way to narrow it down is to take out every other .js include one by one and see if the error disappears. – Onslaught

Answer 1

Do you have another script using jQuery before jQuery is referenced?

Gittel

@Rundell - have you checked firebug/dev tools to make sure that "xxx_files/jquery.js" is actually loading, and you aren't getting an HTTP 404 error? – Gittel

there is no any error in firebug. The error isonly in ie. Chrome and ff has not any errors. – Rundell

I have changed the file names and the problem is solved. Thanks Brett – Rundell

Answer 2

FOR BEGINNERS:

add this code to your file:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js">
</script>

It'll grab the jQuery file from google cdn (according to http://www.w3schools.com/jquery/jquery_intro.asp) I was having this problem

Answer 3

This issue is because there is no reference in the page for jquery...Pleaes ensure that the below js reference or above jquery-1.5.1.min.js is added as reference

<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
