Jquery Tutorial: Select or deselect a radio button
Today was the first time I tried to do this and believe it or not many of the tutorials/examples I found on good ole Google didn’t work. So after about 45 minutes I finally found an example that worked for me. Hopefully you won’t spend as long looking for the answer as I did.
//select the radio button
$("input[name=your_field_name_here][value='the_value_of_that_field_here']").attr("checked","checked");
//deselect the radio button
$("input[name=your_field_name_here][value='the_value_of_that_field_here']").attr("checked","");
