I apologize... Didn't answer the whole question... Yes, for this type of thing I use a separate behavior class (similar to troels') controller. You can make the td's extend this controller class, and one difference I make is that I never put javascript handlers in the markup...
But as far as grabbing the references to all the td's, my method below works. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ryan Gahl Sent: Wednesday, March 01, 2006 1:43 PM To: rails-spinoffs@lists.rubyonrails.org Subject: RE: [Rails-spinoffs] manipulate <td>'s and their content bygrabbingtheir classNames Or... var myTDs = new Array(); $A($("main").childNodes).each(function(tr) { $A(tr.childNodes).each(function(td) { myTDs.push(td); }); }); -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of troels knak-nielsen Sent: Wednesday, March 01, 2006 12:28 PM To: rails-spinoffs@lists.rubyonrails.org Subject: Re: [Rails-spinoffs] manipulate <td>'s and their content by grabbingtheir classNames <p align=\"left\"><b><font face=\"Arial\" size=\"2\">GFI MailSecurity's HTML threat engine found HTML scripts in this email and has disabled them.</font></b></p>You could make a controller-object, which keeps a pointer to the selected index, rather than traversing through the dom each time you change the active cell.
