retreive the value of the radio button

[ss123]

How do I retrieve the values of the selected radio button.

My html is as follows:

<input type=radio name=sel value=’testA’ id=13A onclick=test();>

<input type=radio name=sel value=’testB’ id=13B onclick=test();>


This statement always retrieves the first radio button which is testA
alert(document.getElementById(‘sel’).value);



The ids are different, so what is the syntax to retrieve the values by id.

Thanks

If you are using javascript, you have to use a slightly different method for extracting data from radio button lists:

:: Code ::

for (i = 0;  i < theForm.sel.length;  i++)
{
   if (theForm.sel[i].checked)
   alert( theForm.sel[i].value );
}

theForm would be the name of the form.

You're getting the first item in the radio button array because you're not looping through it is my guess.
