checking radio button value for form validation

kevpho · Jul 31, 2003

Hi,

This is a quick question. Does anyone know the syntax for getting the value of a radio button within my VBScript on the same page. I need to make an if statement that says

"if (radiobutton1 is checked) then
...
else
..."

I can't figure out the correct syntax. I'm getting an error when I use the following:
"Document.formName.fieldName[1].checked"

when a button is checked it is set to True
if the buttons are grouped (named the same) then you loop through them checking for the True condition. If found it is checked. If they are named differently then you just validate the True/False condition

thanks for the quick reply ..

so I have "AND" and "OR" buttons and I'd like to check which one is checked when I submit the form. Depending on which one is selected, an appropriate message should prompt the user.

I found a javascript script that returns the value of the radio button online ... but I'm guessing I can't call the javascript function within my VBScript function can I?

yes you can call a javascript function in the vbscript function.

the javascript function needs to be the first <script> declaration in the page however.

example:
<html>
<head>

<script language="javascript">
function checkRadio() {
var msg = "";
var frm = document.forms[0];

for(x=0;x<frm.length;x++) {

if(frm.elements[x].type=="radio&quot

{
if(frm.elements[x].checked==true)
msg += "Form element: " +frm.elements[x].name + " checked\n";
}
}
alert(msg);
}
</script>

<script language="vbscript">
Function startStrucutre

Dim str : str = "Function will now be called"
alert str

checkRadio()

End Function

</script>
</head>
<body>
<form>
<input type="radio" name="radGrp1">Check1
<input type="radio" name="radGrp1">Check2
<input type="radio" name="radGrp1">Check3
<input type="radio" name="radGrp1">Check4
<input type="radio" name="radGrp1">Check5
<input type="radio" name="radGrp1">Check6

<input type="radio" name="radGrp2">Check1
<input type="radio" name="radGrp2">Check2
<input type="radio" name="radGrp2">Check3
<input type="radio" name="radGrp2">Check4
<input type="radio" name="radGrp2">Check5
<input type="radio" name="radGrp2">Check6

<input type="button" value="click" onClick="startStrucutre()">
</form>
</body>
</html>
