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 found that use onclick='this.checked = false;' worked to a certain extent. A radio button that was clicked would not be selected. However, if there was a radio button that was already selected (e.g., a default value), that radio button would become unselected.

For this scenario, leaving the default value alone and disabling the other radio button(s) preserves the already selected radio button and prevents it from being unselected.

This solution is not the most elegant way of preventing the default value from being changed, but it will work whether or not javascript is enabled.
