How to access the value of a radio button that is checked using YUI?

i have following radio button structure ...

<div id="test">
  <input name="test1" value="a" type="radio">
  <input name="test1" value="b" type="radio">
  <input name="test1" value="c" type="radio">
</div>

how would i go about retrieving the value of any checked radio button?

i have checked the YUI documentation an there is not really any good example.

I would also like to know how to get the element by input name in YUI?

Solution

  • In YUI 3:

    var value = Y.one("#test input[name=test1]:checked").get("value");

    In YUI 2:

    // the null, null, null, true is optional, but returns only the first match
var input = YAHOO.util.Dom.getElementsBy(function (el) {
                return (el.name === 'test1' && el.checked);
            }, 'input', 'test', null, null, null, true);

var value = input.value;
