IE7 .NET and disabled radio buttons

Trying to have disabled radio buttons on a black background was hairy in .NET

Because .NET puts them in spans and sets disabled="disabled" they were getting a white drop shadow. Of course when you have radio buttons on a white background you don't notice this, but on a black background it was ugly.

Here is the javascript we used to strip the spans of the flag (and since the radio input itself was disabled, it still worked fine). Thanks to Josh for coming up with the javascript.

var els = document.getElementsByTagName("span");
for(var i = 0; i<els.length;i++)
{
els[i].removeAttribute('disabled');
}
