What does "it doesn't work" mean? What output do you *expect*, and what do you *get*? — Andrzej Doyle, Nov 12 '10 at 13:39
You got 4 implied globals (x, y, w, h), correct that. Also, why are you putting spaces between the function name and the call operator? Use `foo()` instead of `foo ()`. — Šime Vidas, Nov 12 '10 at 13:54

My guess is you are using this in a browser that does not support it. IE does not support getSelection and Fx 3.7 should be the first one to support the getBoundingClientRect

getBoundingClientRect is a DOM Node method, the result of the getSelection method is not a DOM Node.

There might be a way using the anchorNode, anchorOffset, focusNode and focusOffset properties of the Selection that is returned.

If you use firefox + firebug, you can do console.log(select) and inspect the properties that you have access to.
