All the nodes except from the selecte...

I was browsing Google Code when I chanced upon this project called JSpeed - optimization for Javascript. I noticed one of the optimization was to change i++ to ++i in for loop statements. Before Optimization for (i=0;i<1;i++) {} for (var i = 0, j = 0; i < 1000000; i++, j++) { if (i == 4) { var tmp = i / 2; } if (...

Let's say I attach a javascript "change" event handler to a select element, something that dispatches an ajax request to load some stuff from the server. This is fine in Firefox. However, in IE, the change event will fire every time you scroll rapidly through the combo box options using a mouse wheel. This is troublesome because it spam...

Example: <div id="under_meny" style="display:none;">About Us | Contact Us</div> It looks maybe a bit strange that I want to hide a menu like that, but there is a submenu.

In this case it throws a "Microsoft JScript runtime error: Object doesn't support this property or method". It's only when IE is closed that I get the error. Firefo...
There are 8 cards on the table, with four faces visible and four hidden. Click on a card to turn it and if there's a pip-match or suit-match, show sparks around the associated cards. Problem is, I'm either doing something wrong logic-wise, or .concat() is not working. Because some sparks show and some do not. The whole game could proba...
