I'm not sure if this can be done reliably, but you can try finding the size of the window and determine from that whether it's minimised or maximised or otherwise. This link should help.

a coder was close.

alert(screenX)

when minimized, you get -32000 in firefox.
when maximized, you get -4
when restored, you get something else (the position)

Interesting. Do you know what the values are in other browsers? Is there any sort of consistency in this inconsistency (if you know what I mean)?

i was getting tired so i only tested in firebug last night.

here is a test case for your browser.
it seems ok in IE7 and FF2 for me.

Expand|Select|Wrap|Line Numbers
  1. <html><head><title>dans windowstate tester</title></head><body>
  2.  
  3. announce window state in 4 seconds  <input type='button'  id='' name='' onclick="doMin()" value='run' />
  4.  
  5. <script type='text/javascript'>
  6.         function getWindowState() {
  7.             var S = window.screenLeft;
  8.             if (typeof S === 'undefined' ) {
  9.                 S = window.screenX;
  10.             }
  11.         S=parseInt(S);
  12.             if (S < -4000) {
  13.                 return "minimized";
  14.             }
  15.             if (S > -8 && S < 1 ) {
  16.                 return "maximized";
  17.             }
  18.             return "restored:  " + S;
  19.         }
  20.  
  21.        function doMin() {
  22.            document.title = "change the window state now to what you want to test" 
  23.             setTimeout(" document.title=getWindowState(); ", 4000);
  24.         }
  25.  
  26. </script></body>    </html>

It also works in Safari. In Opera, it works with minimized, but not maximized (gives a value of 649).
