Radio Button

JustWondering · Jul 22, 2003

Hi,

I have a group of radio buttons in page1. When user click submit, if one of the button is not selected, I want to display a msg to tell user must select one to move on.

I have some thinf like this but it didn't work (let user go to next page)

<input type="radio" name="rdbutton">Radio 1<br>
<input type="radio" name="rdbutton">Radio 2<br>
<input type="radio" name="rdbutton">Radio 3<br>

If Request("rdbutton&quot

then problem=true
If problem=true then
Session("errMsg&quot

="Please select one"
redirect to same page
End if.

What's wrong with my code?

this must help:

<input type="radio" name="rdbutton" checked>Radio 1<br>
<input type="radio" name="rdbutton">Radio 2<br>
<input type="radio" name="rdbutton">Radio 3<br>

this will ensure that the user selects atleast one option...

I found the error, something to do with my session("errMsg&quot

.

How can make a popup instead of session?

Just Wondering,

ON YOUR FORM PAGE:
------------------
You are missing something from your radio buttons - a value for each one!

Code:

<input type=&quot;radio&quot; name=&quot;rdbutton&quot; value=&quot;1&quot;>Radio 1<br>
<input type=&quot;radio&quot; name=&quot;rdbutton&quot; value=&quot;2&quot;>Radio 2<br>
<input type=&quot;radio&quot; name=&quot;rdbutton&quot; value=&quot;3&quot;>Radio 3<br>

-------------------------------
ON YOUR PROCESSING SCRIPT:

Code:

<%
Option Explicit

Dim strRadioChoice
strRadioChoice = Request.Form(&quot;rdbutton&quot;)
'or use: strRadioChoice = Request.Querystring(&quot;rdbutton&quot;)

If strRadioChoice = &quot;&quot; Then
    'No button selected:
    Response.Write(&quot;<html><body>You need to select an option.<br><a href=&quot;&quot;javascript:history.go(-1)&quot;&quot;>Back</a></body></html>&quot;)
Else
    'One was selected:
    Response.Write(&quot;<html><body>Option &quot; & strRadioChoice & &quot; was selected.</body></html>&quot;
End If
%>

Thank you.

How can I pass the text item of the radio button to the next page?

I try:

Session("rd&quot

=Request("rdbutton&quot

If i select 1 button, On the next page I got
Session("rd&quot

=ON.

I want the text of that RD not ON or OFF

Sorry...my bad...I must set value="something" to pass along.

o.k there is another way by using javascript (i love it):
<input type="radio" name="rdbutton" checked>Radio 1<br>
<input type="radio" name="rdbutton">Radio 2<br>
<input type="radio" name="rdbutton">Radio 3<br>

<script>
function CheckChecked()
{
sel=0
len=document.getElementsByName("rdbutton&quot

.length
for(i=0;i<len;i++)
{
if(document.getElementsByName("rdbutton&quot

.checked==true)
{
sel++
}
}
if(sel==0)
{
alert("Please select atleast one option box.&quot
}
}
</script>
