Re: how to check if page has been displayed (rendered) by the browser

Unfortunately, this doesn't work this way : you have no guarantee that your
page has finished *rendering* when your script is starting  executing.

Yeah, you're right. And you must use the fact that the scripts contained in
the <head> tag are only launched on demand. Here's a snippet :

-------------------------------------------------------
<html>
<head>
<script type="text/javascript">

function init() { ...}

</script>
</head>



<body>
<script type="text/javascript">
            addEvent(window, "load",initAll);

<!-- When the page is fully loaded, we can do what we wish to -->
            function initAll() {
                       init();
                       ...
            }
</script>
</body>
</html>

-------------------------------------------------------

Cheers,


Pierre
