I created a new ASP.Net MVC 4 project using the template in Visual Studio 2012. After upgrading to jQuery 1.9, the login functionality breaks. Specifically, I get the error
0x800a138f - JavaScript runtime error: Unable to get property 'call' of undefined or null reference
at line 1172, column 5 in jquery.validate.js
How can I fix this issue?
This issue is fixed in jQuery Validation Plugin 1.11.0pre.
Unfortunately there is currently no pre-release build on NuGet, so it is currently necessary to download jquery.validation.js directly from GitHub:jQuery.Validation 1.11 is now available via NuGet (thanks @Simon_Weaver).
UPDATE
It looks like general support for jQuery 1.9 is in the jQuery.Validation code base but not yet released
