Answer 1

In your selector you seem to be attempting to fetch some nested element of your radio button with a given id. If you want to check a radio button, you should select this radio button in the selector and not something else:

$('input:radio[name="cols"]').attr('checked', 'checked');

This assumes that you have the following radio button in your markup:

If your radio button had an id:

you could directly use an id selector:

$('#myradio').attr('checked', 'checked');
