Check first radio button with JQuery

jquery radio-button checked
Matthew picture Matthew · Oct 20, 2010 · Viewed 69.7k times · Source

I would like to check the first radio button of each group. But there are some radio button that are disabled, so the script should ignore them and go to next non-disabled button.

I wrote something like this but it doesn't work:

$(document).ready(function(){
if ($("input['radio']).is(':disabled'))
    {  
        $(this).attr('checked', false );
    }
else
    {
        $(this).attr('checked', true );
    }
});

Thanks a lot

If your buttons are grouped by their name attribute, try:

$("input:radio[name=groupName][disabled=false]:first").attr('checked', true);

If they are grouped by a parent container, then:

$("#parentId input:radio[disabled=false]:first").attr('checked', true);
