get Selected radio button value??

hii

I have a 2 radio button in first.html So i want to get the selected radio button value using DOM APIs.
without getElementById is preferable for me bcoz i am using node.type=="radio"

can anyone help me out??

 

Hi,
in case you have radio as following : <input type="radio" name="yesno" value="yes" /><input type="radio" name="yesno" value="no" />

You just go through all radios (in case of only two radios, you can just check if the first is checked) :
var l = your_form.yesno.length;
for(var i=0; i<l; i++) if(your_form.yesno.checked) var radio_value = your_form.yesno.value
Where 'your_form' is the reference to the form, where the radio is

Hope it helps

 

Please checkout i just want to get the selected value of the radio button.

var cells = table.getElementsByTagName("td");

for (var i = 0; i < cells.length; i++) {
node=cells.firstChild;
// Here is problem
if(node.type=="radio"){
