Default Radio button selected value

Question: AFAIK, to retrieve the selected value for <SELECT> in a single line javascript, I have the following code:
this.form.areaID.options[this.form.areaID.selectedIndex].value

If I were wanted to do the same, retrive the selected value for <RADIO> in a single line javascript, how?

the thing is radio buttons do not work like select boxes.

say you have two different radiobuttons

i.e <input type="radio" name="rad1" value="1">

and <input type="radio" name="rad2" value="2">

then their values can be recieed by

document.formemail.rad1.value
and
document.formemail.rad1.value..


but say you have multiple radio buttons with same name
i.e <input type="radio" name="commonrad" value="1">
and <input type="radio" name="commonrad" value="2">

now this has become an array.
so then you have to run a loop to get the value..

i.e document.formemail.commonrad[0].value will give 1
and document.formemail.commonrad[1].value will give 2

also you will have to check first which one is checked.

to avoid all this i had put an hiddenfield and just assigned the value of the radio button checked so that it can be accessed in a single line of code...
