Today I am trying to figure out how to do validation with TinyMCE editors while using MVC’ s unobtrusive validation.  I did a google search and came up with a large number of results that all said the same thing.  I couldn’t get any of them to work.  While testing I found the following solution.  It isn’t perfect but is pretty close to what I need.

Here is the solution I came up with. I didn’t need to add any other additional code to the page.

      $('form button[type=submit]').not('.cancel').click(function () {
        var form = $('#FormName');
        var isValid = form.valid();
        var istinymceValid = $('#ContentField').valid();
        if (!isValid || !istinymceValid) {
          return false;
        }
        return true;
      });
