document.getElementById() VS. getElementById()

Question

It is common for me to register javascript functions for certain events by doing something like:

myBtn.Attributes.Add(\"onClick\", \"Validate(getElementById(         


        

Answer 1

I dont really know how to explain it but its because the getElementById() finds an element in the html structure of a page. Some browsers know that by default you want to search the document, but other browsers need that extra guidance hence document.
