  • You condition is right but seems to code error change 


    CompModules!="" to CompModules.value !=""

  • Hi Rahul,

    I already tried with this CompModules.value !="" ,CompModules.value !=0,CompModules.value !=null  but after writing this i am getting error in all 3 combinations

    value is null or not an object..........so i tried with CompModules!="" but problem is this is working but running infinitely .....

    i want to clarify 1 thing -i also did a validation (server side).....by AS.Net validation control(regular expression).......if someone enter character then it shud not be accept..........

    and for client side .....i am writing this java script.........if training status== not started && completed modules !="" then alert....................

  • See your function getTagFromIdentifierAndTitle

    returning the object of the control not its value. like for 'd'. So it always return true for your control. First check wether

    your control object is coming from your function or not. Then check the control object is same or returning other object.

    and try below condition

    if( CompModules !="undefined" to CompModules.value !="undefined"
