Your post seems to say that you can use this method to obtain a single value, but doesnt pluck return all the values from all the checked elements? which means it’ll return an array of 1 element which contains the value?

a better way perhaps is like this:

var value = form.down(“input:checked[type='radio'][name='radio_group_name']“).value;

It seems this is slightly simpler, I suppose not a great improvement. But it will return the value itself, not an array containing the value.

Thanks for your solution.

Very elegant, thank you! As a Prototype rookie, though, I’m wondering… don’t you need to have [0] at the end of that line? pluck() seems to return an array, and you want the scalar value for the chosen value. It seems to work just fine as-is, so maybe I don’t have a thorough understanding of how JS arrays work…

Very elegant! I laughed out loud when I read it. I love how you can do this kind of stuff with Prototype.
