I have four radio buttons, all with the same Name value, but different Value values.

<input type="radio" name="cars" value="vw" />
<input type="radio" name="cars" value="dodge" />

Etc.

If there someway I can extract the value of the selected node from that list?

document.getElementsByName("cars").value type of thing?

I ended up just doing a loop, and looking for whichever node had .checked as true - but I'm hoping their is a non-loop way to do this.
