flexible .hide()

flexible .hide()

Hey,

i would like to hide some <tr></tr>'s when the DOM is ready:

  1. window.onload = function(){
  2.       $('tr.nr39').hide();
  3.       $('tr.nr41').hide();
  4. }
The problem is that i would like to hide all tr.nr, not only nr. 39 and 41, and i don't know how many it will be.

Is it possible to hide all <tr class="nr..."></tr> ?

THX,
Dominik
