Radio Submit Button Problem

[JR]

Hi. I hope someone out there who is more versed with JavaScript than
I can help me with the following annoying problem. Here's the
problem.

I have a form with the following layout:

Column A Column B Column C
data 4 radio buttons more data
.... ... ...
.... ... ...

The form does have a submit button that leads to a given CGI script.
The form also has submit buttons as onClick events inside of the radio
buttons, that point to a different CGI script. The problem is that I
need to know which particular radio button triggered the onClick
event, because when I receive the form data, I only want to process
the row of data for which an event was triggered. As the script is
now, I just receive everything from the form, without knowing which
row to actually process. The one thing I thought about trying was to
call a function with the onClick event that would receive a given row
id (1 through up to 279), and the use document.write to create a
hidden value for just that id. I don't know if this is workable,
though. Am I on the right track with this idea? Is this doable, or
should I think about trying a different approach?

Thanks!!!

Don't think you can do document.write after the page has rendered.

Here's what I'd do:

Put in a hidden input field. Create a function to handle the onClick
event. Pass the id of the radio button to the function. The function
then sets the value of the hidden field to whatever the id is.

Make sense?

Thanks for the reply. I'll give this idea a try. It sounds like a
workable solution. If it does work, I'll post the code in my next
reply-someone else out there may have the same problem.

Thanks again.

From what I see, the only way is to have a loop, and check each
radio button for the "checked" property. If you give the radio buttons
the same name, they form an array, so you can use a for-loop.

What about users without support for client-side scripting?

Use several submit buttons with the different name and/or different values.
<input type="image"> may be useful as well, that displays a graphical
submit button, if supported (since HTML 4 IIRC). Then test against the name
or the value of the submit button server-side.

Or use several form elements with different "action" attribute values.

Anything else is considered harmful.

Hi,
I would collect the data input by user, stick them into another form
and submit that form according to the thing that was clicked.

<form name=F1>
<input type=radio name=Rad1
onclick=Chk(thi s.form,this.nam e,this.value)>
<input type=button value="OK"
onclick=Chk(thi s.form,"button" ,"button")>
</form>
.....
<form name=F2 action=Onecgi.c gi>
<input type=hidden name=Val1>
<input type=hidden name=Val2>
</form>
<form name=F3 action=Twocgi.c gi>
<input type=hidden name=Val1>
<input type=hidden name=Val2>
</form>
<script>

function Chk(F,Nm,Val){

if(Nm=="button" { // submit button - fill F2 then submit it
to Onecgi
document.F2.Val 1.value=whateve r
document.F2.Val 2.value=whateve r
document.F2.sub mit()
}

else{ //radio button - fill F3 then submit it to
Twocgi
document.F3.Val 1.value=Nm
document.F3.Val 2.value=Val
document.F3.sub mit()
}

}
</script>

Maybe crude and very redundant but it's 7AM and my brain is not
working ...

Just capture whatever data you need inside hidden fields (be it
data, or id's, or names of controls, whatever), before you submit the
form.

I know it. It's just that sometimes I can't resist pointing out the
obvious...
