getElementsByTagName to return the id

Hello,

I am using getElementsByTagName(‘input’) and would like to return the id of the radio button that is checked. My script returns: ‘undefined’. 😮 I was hoping to see the string that I had set for the id property in my HTML.

Here is what I tried:

function Test()
{

var docButtons=document.getElementsByTagName(‘input’)
for (var i=0; i<docButtons.length; i++)
{ if (docButtons[i].checked == true) {alert(docButtons.id)} }

}

I was leery on ‘docButtons.id’ but figured I would give it a shot. Will someone please help me out?

Thanks ?
