Why can't radio buttons be “readonly”?

Question

I would like to show a radio button, have its value submitted, but depending on the circumstances, have it not editable. Disabled doesn\'t work, because it doesn\'t submit t

Answer 1

I've faked readonly on a radio button by disabling only the un-checked radio buttons. It keeps the user from selecting a different value, and the checked value will always post on submit.

Using jQuery to make readonly:

$(':radio:not(:checked)').attr('disabled', true);

This approach also worked for making a select list readonly, except that you'll need to disable each un-selected option.
