capturing radio button text values 11 years 6 months ago #25807

I'm working with the Calculations Example form. The JavaScript is:
function calculateRadio()
{
var op1=document.getElementsByName('form[radio1]');
var op2=document.getElementsByName('form[radio2]');
var result=document.getElementById('Total2');
 
result.value=0;
 
result.value=parseInt(result.value);
 
for(i=0;i<op1.length;i++)
if(op1[i].checked) result.value=parseInt(result.value)+parseInt(op1[i].value);
 
for(i=0;i<op2.length;i++)
if(op2[i].checked) result.value=parseInt(result.value)+parseInt(op2[i].value);
}

This takes the value of the radio buttons, which are numbers, and does numerical calculations.

What I would like to do is just return values (ie PEDA) as straight text. Then I can use the text in an if .. then code.

But I can't figure out how to get the text values and save them to a variable as text.

Your help is appreciated.

I got it to work. For the benefit of others here are the details.

This is for a registration form for a conference. I needed to capture the text value of the radio button to indicate the registration category. Then I use this code to assign the fee value to the registration through use of an if ... then .. routine. Then the fee is assigned to a field which is used to send a thank you message and for sending to paypal.

Here is the resultant code:
<script type="text/javascript">
function calculateRadio()
{
var radios = document.getElementsByName('form[rgcategory]');
var result=document.getElementById('rgfee');
 
            for (var i=0; i < radios.length; i++) {
                if (radios[i].checked) {
		       vcrgfee=radios[i].value;
if (vcrgfee== "IED1")
   {
   vRgFee=30;
   }
 else if (vcrgfee== "IED2")
   {
   vRgFee=30;
   }
 else if (vcrgfee== "IEDA")
   {
   vRgFee=50;
   }
 else if (vcrgfee== "PED1")
   {
   vRgFee=60;
   }
 else if (vcrgfee== "PED2")
   {
   vRgFee=60;
   }
 else if (vcrgfee== "PEDA")
   {
   vRgFee=100;
   }
 else if (vcrgfee== "SED1")
   {
   vRgFee=20;
   }
 else if (vcrgfee== "SED2")
   {
   vRgFee=20;
   }
 else if (vcrgfee== "SEDA")
   {
   vRgFee=30;
   }
 else if (vcrgfee== "ROD1")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "ROD2")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "RODA")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "KOD1")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "KOD2")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "KODA")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "TOD1")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "TOD2")
   {
   vRgFee=0;
   }
 else if (vcrgfee== "TODA")
   {
   vRgFee=0;
   }
 else
   {
   vRgFee="?";
   }
result.value=vRgFee;
                }
            }
 
}
</script>

The code is called by onClick="calculateRadio();" placed in the radio button Attributes field.
