Hi,

as far as I know, data sumbission is only possible on request so you will be forced to do a POST or GET. In this way you can pass your values by e.g. a hidden field.
I hope this helps ;-).

Hi Sebastian,

Thanks for your suggestion.

I'm not sure if I can use Post or Get. To provide the details of my problems...

I'm trying to pass an array built with data extracted from a MySQL database to Javascript function. These data are extracted after a form POST.

Aim is to dynamically update the webpage using Javascript functions with those data.........

$pass = "yes";
?>
<HTML>
<HEAD>
<TITLE> Gestione Descrizioni Manuali </TITLE>
<SCRIPT language="javascript">

function check(val)
{
alert("value of php var is " + val);
}

</SCRIPT>
</HEAD>
<BODY bgcolor="#FFFFFF" onload="check('<?=$pass?>')">

</BODY>
</HTML>

If I understand you right, you want to take what was returned from mysql via php and pass it into javascript? I've always done it by using php to build the javascript. Method is good for small amounts of data, but if it's a lot of info, I suggest finding a better way, otherise you end up having to xmit a few megs worth of javascript to the client.
