value of radio button...

[Ruskin]

Is there an easier way to do this (what I am trying to do, is have 3 radio
buttons and when the submit button is clicked, easily determine which radio
button was selcted). NOTE: the radio buttons are in 3 different cells of a
table, so I can't use the <select></select> tags....
HTML:
<form name="SelectOrd er">
<tr><tr><inpu t type="radio" name="OrderType " value="C">'C' Orders<br
/></input></td></tr>
<tr><tr><inpu t type="radio" name="OrderType " value="A">'A' Orders<br
/></input></td></tr>
<tr><tr><inpu t type="radio" name="OrderType " value="B" checked>Both Order
Types<br /></input></td></tr>
<tr><tr><inpu t type="button" name="btn1" value="Submit"
onClick="Submit _Form(document. forms[1])"></input></td></tr>
</form>

<script language="javas cript>
function Submit_Form(frm ) {
if (document.Selec tOrder.OrderTyp e[0].checked==true) {
alert('C');
} else {
if (document.Selec tOrder.OrderTyp e[1].checked==true) {
alert('A');
} else {
alert('B');
}
}
}
</script>

Hi Ruskin,

1) use length on the radiobutton-object.
2) loop and check.

something like this:
I didn't check it, so forgive typos and blunders. :-)

<script type="text/javascript>
function Submit_Form(frm ) {
numberOfButtons = document.forms. SelectOrder.Ord erType.length;
for (i=0;i<numberOf Buttons;i++) {
if (document.forms .SelectOrder.Or derType[i].checked){
theVal = document.forms. SelectOrder.Ord erType[i].value;
alert(theVal);
}
}
</script>
PS: Use selectedIndex if you use Select/option elements.
