.val method returning "on" for dynamically created radio buttons in ie9

Reported by: garybentley Owned by: Timmy Willison
Priority: high Milestone: 1.6
Component: attributes Version: 1.5.1
Keywords: ie9 Cc:
Blocked by: Blocking:


  • jquery version: 1.5.1
  • browser version: IE 9.0.8112.16421 (other browsers not affected)
  • os + version: Windows 7

If you dynamically create a radio button via "createElement" and then use the :checked selector and the val method to retrieve the value "on" is returned in ie9. This doesn't happen with a radio button created via HTML.

Test code:

<div id="test"></div><input type="submit" onclick="window.alert (jQuery('#test input:checked').val ());" value="Click Me!" /><script src="/js/jquery-1.5.1.js"></script><script>
jQuery.noConflict ();

var el = window.document.createElement ('input');
el.setAttribute ('name', 'hello');
el.setAttribute ('value', 'world');
el.setAttribute ('type', 'radio');

jQuery('#test').append (el);


The expected output is "world" but "on" is returned.

If you use standard html such as:

<input type="radio" name="hello" value="world" />

Then "world" is returned as expected.

This problem doesn't happen in ie8 but in ie8 and below you have to use createElement with the full html specified for the element.
