The following works on my Mozilla:
<script>
function check(radio)
{
var selected = "";
for (var i=0; i<radio.length; i++)
{
if (radio[i].checked) {
selected = radio[i].value;
}
}
alert ("The checked value is " + selected);
}
</script>
<form action="http://localhost:1234/cgi";>
<input type="radio" name="r" value="b1" checked="checked" />
<br>
<input type="radio" name="r" value="b2" />
<br>
<input type="radio" name="r" value="b3" />
<br>
<input type="button" value="click" onclick="check(this.form.r)" />

Your html is ill-formed. The text field should be:Well, it is not n1, I had the problem with.
input type="text" name="n1" size=20
Even if I 'correct' it, I still can't see
the value of n0 (the radio-button).
Anybody knows how to access the value of a radio-button in JavaScript ?

I have a small problem accessing form-vars via JavaScript.
In below example, I have two vars in a form,
one of type radio (n0)
and a normal input-var (n1).
In the JavaScript Function CheckInput() I can acces the value of
n0, but not of n1
.
Depending on the browser, I get different results:
konqueror : always b1
opera : undefined
mozilla : undefined
galeon : undefined
-----------
<html>
<form name="ArgsForm" onsubmit="return CheckInput()">
b1 <input type="radio" name="n0" value="b1"><br>
b2 <input type="radio" name="n0" value="b2"><br>
string <input name="n1" size=20><br>
<input type="submit" value=" Execute ">
</form>
<Script language="JavaScript">
function CheckInput()
{
alert(document.ArgsForm.n0.value);
alert(document.ArgsForm.n1.value);
return false;
}
</Script>
</html>
-----------
So I must be missing something very obvious here.
Can anybody point me to the right direction?
