i found this code below which works fine in metamod - just do not know how to use a if statement with the info

<script type="text/javascript">
<!--

var viewportwidth;
var viewportheight;
 
// the more standards compliant browsers (mozilla/netscape/opera/IE7) use window.innerWidth and window.innerHeight
 
if (typeof window.innerWidth != 'undefined')
{
      viewportwidth = window.innerWidth,
      viewportheight = window.innerHeight
}
 
// IE6 in standards compliant mode (i.e. with a valid doctype as the first line in the document)

else if (typeof document.documentElement != 'undefined'
     && typeof document.documentElement.clientWidth !=
     'undefined' && document.documentElement.clientWidth != 0)
{
       viewportwidth = document.documentElement.clientWidth,
       viewportheight = document.documentElement.clientHeight
}
 
// older versions of IE
 
else
{
       viewportwidth = document.getElementsByTagName('body')[0].clientWidth,
       viewportheight = document.getElementsByTagName('body')[0].clientHeight
}
document.write('<p>Your viewport width is '+viewportwidth+'x'+viewportheight+'</p>');
//-->
</script>

?>
<script type="text/javascript">
if(window.innerWidth < 400) {
    document.writeln('hello');
}
</script>
<?php


i got this to work - but now i would like to know if it's possible to return a module in a script? I tried below, but that does not work

?>
<script type="text/javascript">
if(window.innerWidth < 400) {
    return 75;
}
</script>
<?php

i am no coder but understand that you cannot mix the stuff - how about going the other way around to have your normal if statement - then call the script in in it and if it's true, return 75? - i found below - maybe it could help you in some sort of direction i HOPE...

if ('<script> document.write(window.innerWidth); </script>' < 1008) retrun 75;
