explanation of "this"

[Jason S]

I have a rough understanding of what the "this" keyword refers to in
Javascript but am not very clear on it. Is there a good reference that
explains it well?

Clientside html javascript "this" is a reference in itself,
it references to the object it is called in.

<div onclick='alert(this.id)' id='blah'>clickMe</div>

will show in the alert box the id text 'blah'.

For 'this' reference in prototype/constructor:
