Get value of class of a DIV using JavaScript

Question

Question is simple. Not using jQuery... how do I get the value of class value in a DIV using regular JavaScript?

Thanks.

Should've posted at least a little HTML to make your post more clear. — Kellen Stuart

Assuming this HTML

<div id="Target" class="MyClass" />

Like This

var ElementCssClass = document.getElementById("Target").className;

+1 @Jahkr: Or if not getElementById, it might be from the list returned by getElementsByTagName, or you might navigate to it from another element via childNodes, parentNode, etc. Details: w3.org/TR/2000/REC-DOM-Level-2-Core-20001113 | w3.org/TR/2003/REC-DOM-Level-2-HTML-20030109 | w3.org/TR/DOM-Level-3-Core

Very odd that the OP accepted the other answer. I guess it was having both the HTML and the JavaScript that made it more useful to them, showed more clearly how they linked up.

especially since the original answer was "use getAttribute"... I dislike edits on here sometimes.

@cwolves: Actually, that was a different answer, which the answerer deleted after getting repeatedly downvoted. (It was pointed out to him that it didn't work, and he said "okay, thanks" and then left the answer as it was, didn't fix it, didn't delete it. Hence the downvotes.) Mimisbrunnr said className right away.

@cwolves: I should explain that it's not that I have an obsession and/or incredible memory. There's a rep level where you can see deleted answers. :-)
