Assunto: [jQuery] dynamically building the "for" attribute



I have a series of labels and checkboxes.

The checkboxes' IDs are generated on the fly, so I have no way of
knowing the id at the server (without a lot of heavy lifting).

I'd like to do this in jquery...

here's what I have so far

HTML
<input id="Checkbox1" type="checkbox" value="x" /><label>something</
label><br />
<input id="Checkbox2" type="checkbox" value="x" /><label>something</
label><br />
<input id="Checkbox3" type="checkbox" value="x" /><label>something</
label><br />
<input id="Checkbox4" type="checkbox" value="x" /><label>something</
label><br />

jquery

$("label").attr("for", $
(this).somethingToGoHereToSetTheIdOfThePrevElement.text
()                      );

I'm missing the way to traverse this
