Uncaught TypeError: Cannot set property 'unobtrusive' of undefined

Question

I am getting this error in the Chrome JScript debugger. It happened when I switched to the Microsoft CDNs for the scripts below.

I\'m not sure how to work around t

Answer 1

Another reason this error can occur is if you load the unobtrusive script before jquery.validate.

So,

<script src="/scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="/scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>

is OK, but:

<script src="/scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>
<script src="/scripts/jquery.validate.min.js" type="text/javascript"></script>

will give the "Cannot set property 'unobtrusive' of undefined" error.

Answer 2

Found it. I was missing two lines:

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/additional-methods.min.js"></script>

I learned this by reading this page which describes how the jquery.validate.unobtrusive script works.
