form, array and javascript function

[Anon]

Hello,

I am trying to create a dynamically generated form with checkboxes.

Here is a sample code :

while ($i<$ncomp) {
?>
<input type="checkbox" name="comp[<? echo"$i";?>]" value=<? echo"$val"; ?> onclick="chg(comp[<? echo"$i; ?>)">
<?
$i++
}

and the beginning of the code for the "chg" function :

function chg(component)
{
if (composant.checked==true) ...

I have a javascript error (variable comp not definde). What is the problem with this ?

In advance, yhank you for any help.

The onClick part of your checkbox field looks like it is missing the ending square bracket "]".

onclick="chg(comp[<? echo"$i; ?>)"

Try changing it to:

onclick="chg(comp[<? echo"$i; ?>])"

That way it will append the $i variable to the "comp" so that you get comp1, comp2, etc. as your field names.
