Hello:
On a web page I check the value of a cookie and set one of two radio
buttons accordingly.
function setRadioForm() {
var myCookie = document.cookie;
var OpenOnly = myCookie.substring(9);
if (OpenOnly == "True") {
document.ViewOptions.Open.checked = true;
}
else {
document.ViewOptions.All.checked = true;
}
}
<body onload="setRadioForm()">
This works fine. The correct radio button appears checked when the
form opens. However, when the user checks one of the buttons (usually
the unchecked one), both buttons remain checked.
Here's the code on the form:
<form name='ViewOptions">
<input type="radio" name="Open" value="True"
onclick="setCookie("True")> Always, show me open items only.
<input type="radio" name="All" value="False"
onclick=setCookie("False")>Always show me all items, open and closed.
</form>
The onclick fires correctly, but the button which was not clicked
remains checked. Am I doing something wrong or is this a limitation
in the browser/code?

When you have a group of radio buttons (I.E. only one can be selected), you
need to name them the same. The checked value, if any, will be the only one
returned under that name. Since they are named the same you need to access
them like so: 1st radio button: document.ViewOptions.Open[0].checked 2nd
radio button: document.ViewOptions.Open[1].checked

Make sure the quotes match: name="ViewOptions" or name='ViewOptions'
<input type="radio" name="Open" value="True"

Use a different quote character when nesting:
onclick="setCookie('True')">
....and make sure that quotes are paired.
<input type="radio" name="All" value="False"
onclick=setCookie("False")>Always show me all items, open and closed.

Radio buttons must belong to the same 'group' in order to have interaction
with each other. You do this by giving them the same name. Using your code
above, you could do this like so:
<FORM name="ViewOptions">
<INPUT type="radio" name="items" value="open"
onclick="setCookie('True')"> Always, show me open items only.
<INPUT type="radio" name="items" value="all"
onclick="setCookie('False')"> Always show me all items, open and
closed.
</FORM>
With this new arrangement, you might want to rename your cookies (True and
False don't quite make sense in this context).

Michael, Thank you. The quoting in my code was correct. I transcribed
it wrong in the message.

</FORM>
I thought I had to name them differently to reference them. Thanks.

Right, Thanks.

So now you've learned why you should *never* transcribe code
into a post when you're asking why it doesn't work. It's
like sending your brother in to the doctor to find out why
your shoulder hurts.
Always copy and paste code that you know shows the problem.

Right you are. The code was on a machine not corrected to newsgroups,
and I knew the problem had to be more conceptual than syntactical, but
I take your point.
