NEW to JavaScript, easy question

[dragonsbb16]

Hello,
I am new, so bear with me.....
I have a contact form.....then you click submit......it opens a new page that displays "message has been sent" then it redirects you based on this code

<script>function update(){top.location='index.html';}var refresh=setInterval('update()',5000);</script>

My Question is how can i change this code to CLOSE the "Message Sent Page" rather than REdirecting you? Thank You for any help.

<script type="text/javascript">
onload= function(){
setInterval('self.close()',5000)
}
</script>
Unfortunately for you this will work for IE only (and with an alert message included, nothing to do about it). Mozilla will simply refuse close a window if the window is not opened using javascript methods. This is it. You should try to manage this from a server-side level.
