[jQuery] contains() with a jquery object reference (form field)

[Graeme B. Davis]

I'm trying to highlight some rows of a table, and previously did this with
the following code:

$('#sqltable').find('td').contains($('#workgroup').val()).toggleClass("highl
ight");

The new code:

$("#sqltable tr td:contains(TEXT TO SEARCH FOR
HERE)").toggleClass("highlight");

How do I specify $('#workgroup').val() for the text to search for, like the
first example?

Thanks in advance.... It's just not clear to me... I've also tried
.filter(':contains($('#workgroup').val())')
