hi there is one function called isNaN with the help of this function we can identify whether the value is null or not var testString; var boolTest = isNaN(testString); Please refer http://www.w3schools.com/jsref/jsref_isnan.asp http://msdn.microsoft.com/en-us/library/ie/66ztdbe6(v=vs.94).aspx hope this will help you.
