not only top but also body seen

top

<script type="text/javascript">
var msg = "Are you sure?";
if (confirm(msg)) window.location.replace('http://yahoo.com');
else window.history.back();
</script>

bodyThe code above pop-ups an alert when it is loading.

When the alert pops, the user can see the text "top", but can't see the text body.

I like to make it the text body seen to the user.

Can I do it with your help?

The page is rendered top to bottom, so put it at the end of the page or call it on window.onload.
