[jQuery] UNfocus() ?

[Kenneth]

I am trying to emulate the :focus selector for IE, and I have succeeded in
the initial aspect of that with the following:

   $inputs.each(function(){
           $(this).focus(function(){
               $(this).addClass('focus');
           });
   });

However, once the focus leaves the field, the class remains applied. Surely
I don't have to manually iterate $inputs and remove .focus if it's applied,
and then add it to the current input, do I?

Thanks in advance for any help.
