In general, in the JavaScript console, if it states:

Uncaught TypeError: Object #<HTMLDocument> has no method 'getElementByID'

what is the typical problem in your code? I'm new to JavaScript and in writing a program, this has repeatedly e up and I'm not sure how to fix the problem or what could even possibly be the problem.

• user1248795, if indeed the problem was simply that you had ID instead of Id then you should accept either davin's answer or mine. If it was something else, then you should edit the question to make it clearer that there's a further problem. – Gareth McCaughan Commented May 2, 2012 at 9:30

getElementById not getElementByID

Lower case d. JavaScript is case-sensitive.

The typical problem is that you've typed getElementByID when you meant getElementById, probably. Alternatively, if that mistyping happened in transcribing the error message rather than in your original code :-), perhaps you did something that you thought would produce a DOM object but that actually produced null or undefined or something; there are lots of ways for that to happen.

The right method name is document.getElementById.
