Radios and JQuery and IE8
I have to send a thank you out to pixeltastic.com for their post: Selecting Checked Radio Button with JQuery in IE8 it really saved me some time. I was trying to figure out why I couldn’t get the checked qualifier to work for IE8 when it worked everywhere else. The best part about this is you can combine it with regEx style searching and do something similar to this:
$("input[id^=fieldid]").filter(':checked').val();
To get the checked values from your radio list where the beginning of the id matches fieldid.
