The solution here is to give all of the radio buttons within the group the same name but different values.
Here is the code used for the radio button themselves.
Basically, when the submit button is clicked, I want the script to verify a radio is checked, if one is checked to do nothing.
That completes the coding of the radio buttons themselves.
The final step is to set up the radio button validation using Java Script.
Check the method used in the above code By simply putting the JS code to perform the validation will do the validation.
There is a on Submit event that will be invoked when you press a submit button, call the validating code (keep that as a function) so that it will be invoked just before passing the data from the client to the server.
The first thing that to look at when using radio buttons on our form is how the buttons need to be coded in order for them to function properly as radio buttons.
