What version of javascript does IE6 and IE7 use

Posted on 2009-07-15
Last Modified: 2013-12-08
I am trying to calculate the difference between dates in years and months.  I was delighted when I found the functions getFullYear and getFullMonth.  However when I use them I get the following error:  Object doesn't support this property or method.
My research shows that the functions were implemented in javascript 1.3.  Some sites show IE6/7 has using version 1.2 and others 1.3.  Which is it?  Or do I just I have my syntax wrong?  I am using IE7, Visual Studio 2008 and C#.
Thank you.
relevent code:

var BDate =  document.getElementById("txtBirthdate");

            var ODate = document.getElementById("txtOnsetDate");

            var BOD = Date(BDate.valueOf);

                 var years = BOD .getFullYear() - BOD .getFullYear();

Open in new window

Use "new" to create an object:

var BOD = Date(BDate.valueOf);

Open in new window

Opps, I said it right, but "copy and paste" it worng... The right should be:

var BOD = new Date(BDate.valueOf);

Open in new window

The actual statement is var BOD = new Date(BDate.value);  The new statement was the key.  Thank you.
