How to find the value of a radio button

[donpro]

Hi,

Does anyone know how to use DOM to find the value of a selected radio
both (or if none were selected)?

My web page displays a set of radio buttons - the number is dynamic so
could be one or 100; I do this within a loop.

At the moment, I'm giving each one the same name and ID - not sure if
giving the same ID is correct or not. By default, no radio buttons
are selected when the page loads

When the user clicks on a a specific button on the page, I need to
check if a radio button was selected or not. I trap the 'click' event
but my code to get the radio button value has failed.

Thanks,
Don

A good place to start is the group FAQ

The longer FAQ note linked in the answer to the above FAQ is valuable.

Yes, see Peter's reply.

It is not correct, the value of each ID attribute must be unique in
the page. Giving buttons the same name is OK, it forms them into
groups. Onlly give them IDs if they really need them.
