[jQuery] Jquery 1.2.3 does not return a type for radio controls?

[Scott Sharkey]

Hi All,
I'm stuck with Jquery 1.2.3 in a trac-based application.  I'm trying to 
get the type of a form control, to determine what mechanism I should use 
to set it's value (ie, text controls use .val(), checkboxes get 
.attr("checked", "checked") etc.).  When I fetch my list of controls, 
and loop through them with each, printing the value of .attr('type') on 
each... the text, checkbox, and textarea types work fine, but radio 
controls come up undefined. Is this a jquery bug?  Does anyone know 
if/when it was fixed?  Maybe I can port that patch back to 1.2.3 to 
solve my problem.

Any other suggestions appreciated.
