JavaScript; Little Prob

Euch! IE tastes horrible!
[ * * * * * ]
 I will point out here I know no javascript; I'm trying to blag it.

OK, on my site, I want javascript to detect the monitor resolution, and depending on it, take the user somewhere else.

I currently have:

Code:
 
<script language="text/javascript">
function detect(){
if(screen.width==800&&screen.height==600)
{
 self.location="index1.php";
}

else if (screen.width=1024&&screen.height==768)
{
 self.location="index2.php";
}

else if (screen.height==1200&&screen.height==1024)
{
 self.location="index3.php";
}

else
{
 self.location="index.php";
}
}
</script>


Any help would be greatly appreciated.

 Correct me if I am wrong, but you can only have one else statement, and it is window.location

 OK, if that is the case, can someone write me a switch...case statement, or whatever I'd need to use, please?

 your if() {
} else if {
} else if {
} else {
}

should be fine, i know it is with php, not sure about the syntax of JavaScript though.

 It's fine in JavaScript.

It's the same syntax as in PHP. But you can't use colons like in PHP.
This is JS ifelseifelse :
Code:
 
if (condition) {
   conditional stuff
} else if (condition) {
   conditional stuff
} else {
   conditional stuff
}

If your conditional stuff for a condition is one line, you can leave out the curly braces enclosing it.

 OK, so now I have:

Code:
 
<script language="text/javascript">
function detect(){
if(screen.width==800||screen.height==600)
{
 window.location="index1.php"
}

else if (screen.width==1024||screen.height==768)
{
 window.location="index2.php"
}

else if (screen.height==1200||screen.height==1024)
{
 window.location="index3.php"
}

else
{
 window.location="index.php"
}
}
</script>


And it still doesn't work.

My mate said to try putting this in the body:
Code:
 
<script language="text/javascript">
detect();
</script>

So I've tried with and without it, but still no luck. Any more help?

If you use
Quote:
 
<script type="text/javascript">

and include detect() (a function has to be called, otherwise the code isn't run), it should work.

The way you have it now, browsers will detect "text/javascript" as being the script language. That script language doesn't exist, so it won't be run.
type="text/javascript" gives the script the "text/javascript" MIME type, which means as much as "text that should be handled as javascript". And modern browsers know how to handle that.
