That book is so cool! =P Anyways, it said that browsers with Javascript, but not a recent enough Javascript would not display the Noscript.

Nice -- now instead of two different pages (i.e.,
index.php, jstest110.php) , make it one.
Here's my solution: http://www.sperling.com/js_detect3/
?php
if (!isset($_GET['js']))
{
echo(script
type='text/javascript'location.href='index.php?js=ok';/script);
}
else
{
$js = $_GET['js'];
if($js != ok)
{
$js = no;
}
}
?
Now, depending upon the value of $js, do whatever.
It would be cool if I could send js value via a
POST instead of GET-- can that be done?
tedd
PS: I read somewhere that using noscript is not recommended.

you additionaly can surround the meta redirect with noscript tags: script !--// index.html D=new Date() location.href='jstest.php?js=okt='+D.getTimezoneOffset() //--/script noscript meta http-equiv='refresh' content='0;url=jstest.php?js=no' /noscript tedd wrote: At 9:55 PM +0100 1/2/07, Satyam wrote: - Original Message - From: Robert Cummings [EMAIL PROTECTED] To: Jürgen Wind [EMAIL PROTECTED] Cc: php-general@lists.php.net Sent: Tuesday, January 02, 2007 8:57 PM Subject: Re: [PHP] Javascript detection , working version On Tue, 2007-01-02 at 11:32 -0800, Jürgen Wind wrote: Robert Cummings wrote: Out of curiosity, can you guarantee the Javascript redirect will always occur before the meta redirect when Javascript is enabled?

Your solution was very simple and worked very well. tx, i always try to keep things logical and as simple as possible ;) this is just a quick example to show how to bring info gathered by js back to the php application (and possibly store it in a session for later use). Using the query string is just one way and can also be used in combination with loading some css.php or some such. Setting a cookie may be another option.
