I see you're using the JS 1.6+* Array.prototype.every method which is a Mozilla invention. To make your code cross browser, you can add this 2 liner[code]Array.prototype.every = Array.prototype.every\|\|function( callback, that ) { for( var i=0; i<this.length && callback.call( that\|\|this, this[i] ); i++ ); return i==this.length; }[/code]This at least makes the script work in Opera 9.5, but thows in IE7. Will try to figure why. Regarding mouse capturing, for line optimized things, you can do it in 2 lines.[code]element.onmousemove = function( event ) { var event = window.event\|\|event; window.mouse = { x:event.offsetX\|\|event.pageX, y:event.offsetY\|\|event.pageY, b:event.which\|\|event.button?true:false } }[/code]Where [i]element[/i] is an overlayed element on top of the area you want to capture the mouse. HTH As for my saying about using an array instead of classNames, I don't know for sure. It's more a gut feeling. OTO the functions hash table technique is really compact. *: wouldn't be great if there was a standard body for JavaScript instead of browser vendords adding whatever they want with no discussion. :o I'm really looking forward to ES4 [url=http://www.p01.org/][img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_love_small.gif[/img][/url] [small](Edited by [url=http://www.ozoneasylum.com/user/2185]poi[/url] on 01-29-2008 20:39)[/small] Loading...
