Publishing HTML(Page content) field required field validation is not working

Question

The required field validation is not working on Site Column of type "Full HTML content with formatting and constraints for publishing". I found a link i.e.
https://social.msdn.microsoft.com/Forums/office/en-US/7b544aae-2562-4b8e-8e5b-36a1d47a4d14/publishing-htmlpage-content-field-required-field-validation-is-not-working?forum=sharepointdevelopment
which tells this is a hot fix in July 2014 CU . Can anyone help me with what all Fixes are there in July 2014 CU. So that I can update only if it required!
Or any other alternative where I can use the required field validator on "Full HTML content with formatting and constraints for publishing" column type?

Answer 1

You could add a scripteditor webpart on the newform.aspx page and add client side validation using jQuery.
$(document).ready(function()
 var fname = document.getElementById('fname').val();
 var lname = document.getElementById('lname').val();
 var age = document.getElementById('age').val();
 /*Do not know how to get element by class and that too, two different type. Have to check if user chose anything or not*/
  $("#submit").click(function()
   if(fname.length === 0)
    alert("Please input a first name");
   else if(lname.length === 0)
    alert("Please input a last name");
   else if(age.length === 0)
    alert("Please input an age");
