Radio button value 1

[DaveC426913]

Huh. A search returns zero hits for 'radio'.

Anyway, hopw can I return the value of a radio button selection?

I thought one of these might:

form.radiobutton.value
form.radiobutton.checked.value
form.radiobutton.selectedIndex.value

depends. If you have two radio buttons (or more) with the same name, then something like this:

var theVal = document.forms['formname'].elements['radioname'][red][0][/red].value;

Where 0 is the first radio button, 1 is the second, etc.

That doesn't tell me which is checked though does it? Do I have to loop through them?

yup. general concept:

var val;
var rbGroup = document.forms['formname'].elements['radioname'];
for (var i = 0; i < rbGroup.length; i++) {
    if (rbGroup[i].checked) {
        val = rbGroup[i].value;
        break;
    }
    alert(val);
}
