Targeting an iframe element using colorbox

I have a link displaying the contents in the colorbox plugin via the iframe method and would like to target specific elements inside the iframe.

Can't seem to figure it out. Below is where I am at...any help would b开发者_运维知识库e greatly appreciated.

$(".thickbox").colorbox({iframe:true,width:450, height:570, title: 'Form Title', 
   onComplete: function() {
    $("#cboxLoadedContent iframe").contents().find("a.login").css("display","none");
   } 
  });

I would use Firebug and set breakpoints so you can browse through the DOM and find the path you're looking for.

Break up that $("#cboxLoadedContent iframe")... line into multiple lines, set breakpoints on each to make sure you know where it's going wrong and debug from there.
