How can i pass a parameter array from PHP to a Javascript function

[Miguel]

Hello.

I have a Javascript function that validates an specific form. As
parameters this function receives an array of elements to be checked.
Depending on the form in cause, the array could have variable lenght.
I don't know how can i pass a dynamic array on 'onsubmit' event form
PHP code to a JavaScript function.
I would like to do something like:

<script>
function Valid_Form(Elem entsArray)
{
alert (ElementsArray[0].value);
alert (ElementsArray[1].value);

return (true);
}
</script>

....

<?php
...
echo "<form method='post' action='?oper=c onfirm' onSubmit='retur n
Valid_Form(this .elements[0], this.elements[1])'>";
...
?>

But it don't work!
Anybody can help me please.

Thanks
Regards
Miguel

That's because you're not passing an array, but rather a list of
parameters. To wrap it in an array, you need to add an Array
constructor, like so:

Valid_Form(new Array(this.elem ents[0], this.elements[1]))
