check all checkboxes...

Can somebody show me how to check all checkboxes in a form with JavaScript? Like in Hotmail, you've got that "Check All" checkbox at the top of the Inbox.

Thanks

From our very own John Percival :

function CheckAll() {
	for (var i=0;i<document.form.elements.length;i++) {
		var e = document.form.elements[i];
		if ((e.name != 'allbox') && (e.type=='checkbox')) {
			e.checked = document.form.allbox.checked;
		}
	}
}

Of course you have to name your INPUT fields appropriately.

Thanks Arien, I take back all but 4 bad things I've said about you. (I need to keep some in reserve)

Thanks, I guess.
