need to know if JS is enabled

itaym02

Hi,

I need to know if the client browser enables JS or not. What is the best way to do it?
(From a PHP script ofcourse)

Regards

echo '<html>
<head>
 <meta http-equiv="refresh" content="15;url=http://www.example.com/index.php?js=no" />
</head>

<body onload="location.href=\\'http://www.example.com/?js=yes\\'">
  <p>Please wait, testing some stuff...</p>
  <p>Click <a href="?js=yes">here</a> if you have javascript enabled</p>
  <p>Click <a href="?js=no">here</a> otherwise</p>
</p>
</body>
</html>';

you have to test with javascript
php can't be used for that directly

hmm

I wish the check to be transparent to the user.

Can I write a php code that will echo "<a href="somthing">somthing</a>

And then add a JS that will change that echo. So, If JS is disabled I get the original <a> tag. IF JS is enabled, I get the JS <a> tag.

Is it feasible?

Thanks

You can't alter the PHP output with javascript since they work on opposite sides of the connection. You could try something like this:

if (!isset($_GET['js'])) {
    echo '<script type="text/javascript">
          window.location="' . $_SERVER['PHP_SELF'] . '?js=true"
          </script>
          <noscript>
          <meta http-equiv="Refresh" content="0;url=' . $_SERVER['PHP_SELF'] . '?js=false" />
          </noscript>';
} else {
    echo $_GET['js'];
}
