The onclick event handler for the radio button is called before the previous
value of the radio button is cleared. This is different than with Netscape 4.x
and IE. In these other browsers the current Radio array element is marked
checked, the old element is cleared, and then the onclick event fires.
The following code demonstrates having two radio buttons marked checked at the
same time:
<html>
<head>
<title>Radiobutton onClick and checked attribute test</title>
<script type="text/javascript">
function clickRadio()
{
var t = document.forms[0].cb; //or document.getElementsByName("cb");
var str = "";
for (var i=0; i<t.length; i++)
str += t[i].value + ":" + t[i].checked + " ";
alert(str);
}
</script>
</head>
<body>
<form>
<input name=cb id=cb0 type=radio value="0" onclick="clickRadio()" checked><label
for="cb0">Zero</label><br>
<input name=cb id=cb1 type=radio value="1" onclick="clickRadio()"><label
for="cb1">One</label><br>
<input name=cb id=cb2 type=radio value="2" onclick="clickRadio()"><label
for="cb2">Two</label>
</form>
</body>
</html>
Click on item One and the alert shows "0:true 1:true 2:false". Having two
elements marked checked makes it hard to tell which is the current item in the
radio set.
Expected Result is for the alert to show "0:false 1:true 2:false". I'd expect
this breaks a lot of existing pages.
This may be a problem with the previous fix in bug 42972.
It also appears that the radio buttons are acting like checkboxes. You can click
on a radio button that is set and it will clear itself, the alert will show
"0:false 1:false 2:false" and then it will reset to be marked.
