[BNM] jquery traversing help!

[paul perrin]

Bit new to jquery but...

I would look at adding the ID to the TR (after all it is the entire row that
is dependent on the key), and then use

$(this).parents("tr:first").attr("id")
Haven't tried it - but if I understand the docs it would work - it should
drill up to the the first tr parent element and then return its id... If you
start nesting your tables you are on your own :-) because it drills up this
could be on any element with in the table row (even an anchor in a span in a
td etc...)

parents seems to return in reverse order, so first should be the nearest
tr...
