Can you show the code?

Check whether b.className has value before using a split method on it.Most likely you are getting b.className as undefined.

Make sure that b object is not null and the className too.
moreover Array.contains is not a part ofjavascript array object, you should define an array prototype for it. Array.contains[^]

Try this code.

JavaScript

Sys.UI.DomElement.containsCssClass = function (b, a) {
               var temp;
               if (b != null || b != undefined)  // null handing
                   if (b.className != null || b != undefined) // null handling
                       temp = b.className.split(" ");
               return Array.contains(temp, a)
