Radio button value

[Claus Mygind]

In my script I used to test the value of the radio button to verify which button was selected. I was able to do that because all the buttons have the same name. If I want to use the the proper

document.getElementById()

notation.

Will I have to:
1) assign a unique id to each button
2) test if that id is "checked"

Or is it proper to use

document.getElementByName()

and then test the value in the same manner I did before?

Yes, the IDs need to be unique, and yes, document.getElementsByName() is OK (don't forget the "s") and probably easier to deal with.

I really cannot get any of it to work.
I use FireFox and any reference to

document.getElementByName()
document.getElementByNames()
document.getElementByTagName()

generates an error "is not a function".

Now I am trying with Id and giving a unique id to each button, hopefully that will work.

There's no getElementByName() method, it's getElementsByName() - notice the difference (see link).

Thanks. That had been bothering me for awhile.

You're welcome.
