After reading the subject, I actually thought this was going to be about
server side javascript... (Which does exist to you nay-sayers.)
One quick solution that I have done before for detecting javascript on a
client is in the document have something like:
<?php
if(!isset($_GET['js']) && !isset($_SESSION['js'])){
$js=<<< eos
<script type="text/javascript">
window.location.href='{$_SERVER['REQUEST_URI']}?js=1';
</script>
eos;
}else{
$_SESSION['js']=1;
$js='';
}
?>
<html>
<head>
<title>Javascript test</title>
<?php echo $js ?>
</head>
<body>
Javascript has <?php if(!empty($js)){ echo '<b>not</b>'; } ?> been
detected on the client.
</body>
</html>
Of course, if the REQUEST_URI already contains a query string, you'd
want to append the js var instead of how I have it above, but it
illustrates the method anyway.
