I have a javascript code that captures the ip address of da visitor and sends it to a page in my website when da visitor clicks a button on da current page.

This is da script:
<script language="javascript">

var ip = '<!--#echo var="REMOTE_ADDR"-->'
function ipval() {
and da script which displays da button, which on getting clicked, sends da ip to a page (login.php) is a form with a hidden field and a button:

<form method="post" action="login.php" name="myform">
  <input type="hidden" name="ipaddr" readonly> 
  <input type="submit" name="submit" value="send ip!">
Now Isn't there any way by which the ip addres of da visitor automatically gets sent to da page login.php as soon as he opens da page??? plz help.
