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

When you use getElementById() and it works that mean that the function where it's called is running on the context of the document, that's is this == document.

So, you should ALWAYS use document.getElementById to avoid that kind of errors.

Anyway, I would even stop using getElementById altogether and start using JQuery, i'm sure you'll never regret it.

Your code would look something like this if you used JQuery:

$("#myBtnID").click(function () { Validate($("#myTextboxID"))});
