//start newbie javascript question

I'm trying to change my page layout depending on a user's screen resolution via javascript. If a user is 1024x768, I want a script that scrolls aross the top of the page to apear. If they don't meet the requirements, I don't want the script to appear.

I figured I could use the screen.width to help me determine what the user's screen size was and then display the file imported via php. Unfortunatly it's not working and I receive a "parse error, unexpected T_CONSTANT_ENCAPSED_STRING " message. I've got different style sheets being used depending on resolution but I can't get this script to work:


<script type="text/javascript">
<!--
if ((screen.width >= 1024)){
document.write('<div id="top">');
document.write('<?php');
document.write('include \'cloud_scroll.php\';');
document.write('?>');
document.write('</div>');
}
-->
</script>


If I add an escape character before the "?" ('<\?php') ) ,that gets rid of the parse error but the php portion of it doesn't work and the cloud_scroll.php file isn't included.

Is the problem with the way I'm using document.write?

I think that it can't work the way you want, as php is a server side language and you can't call it from javascript, that it's a client side language (that is, executed by the browser)

You might want to use an iframe for this...if the resolution test is passed, document.write the HTML for the iframe (embed the script in the <body>) which will allow you to download the PHP script into the iframe for display. As noted, a PHP include is meaningless on the client.

Careful:
