Check for Radio Button's Presence

[bont]

I have a situation on a form, where I do the following (pseudo code)

for k = 0 to 128 do
if eval(FormName & ".Radio_" & k) then
...
end if
end for

What I am trying to do is cycle from 0 to 128. IN doing so I have several radios on the html page that have the name with syntax:

FormName & ".Radio_" & k

When I alert the returned value, I receive a value of [object] when the button is found and "undefined" when it is not found. I want to exclude the "undefined" ones from the ... processes. What kind of coparison can I use for this, or is there a better way completely?

NO I can't give show you the code. The basic setup is this:

For i = 0 to 128

/ I need some condition here to see if radio button with the sequence number of i is present on the page or not i.e. eval("radio_" + i + ".type&quot.

The example I use here returns different values ("

...

/ End condition here



endfor;

You said that eval(FormName & ".Radio_" & k) returns [Object] or undefined so why not use

if(eval(FormName & ".Radio_" & k)!="undefined&quot{
...
}
