[jQuery] Re: Interacting with TR an TD

[Ian Struble]

Building on Karl's example and your new all-td's-must-be-empty
requirement; mark all the TR's with a target class then sweep through
the TD's and get rid of the target class if you find a td that is not
empty.   Play around a bit and see what else you can come up with.

$(document).ready(function() {
 $('tr').addClass('allEmptyTds');    // mark
 $('td').each(function() {
   var $this = $(this);
   if ($this.html() !== ' ') {
     $this.parent().removeClass('allEmptyTds');  // and sweep
   }
 });
});

Thanks guys, that really helped, specially Karl Swedberg's piece of
code. The problem is: the class must only be applied to the TR only if
ALL children TDs have &nbsp; inside... I'm having a hard time making
it work, I'm still learning how to use jQuery properly.
