Disabling a Radio Button
Question: How do I disable a radio button
in a form (making it not selectable)?
Answer:
To make a radio button not selectable, in the button's
INPUT
tag you can use an
onClick
event handler like this:
<INPUT type="radio" name="myButton" value="theValue"
onClick="this.checked=false;
alert('Sorry, this option is not available!')">
In the example below, the "Courier delivery" option is disabled.
Try it now - you'll get an alert box
with the text Sorry, this option is not available!
