Prototype Javascript Framework Screenshot

Prototype Javascript Framework Screenshot


If you use Prototype JavaScript Framework’s event handling and try to use return false; to prevent default, it won’t work. The reason is that under Prototype, the return false no longer works, to make prevent default work, you must use Prototype build-in method: Event.stop. For instance:


Event.observe(link, 'click', dosomething, false);
function popup(e) {
//do popup
Event.stop(e);
}

If you are an experienced Windows user, and wondering whether it’s possible to create, read, use and edit Microsoft Office Excel file on Ubuntu. The answer is that it’s not only possible but also free on Ubuntu.

So you can enter any existing database name at your server as the Default Schema, and it’s not a big deal if you choose to leave it blank, you can always select the database at anytime after you connect to the server.

Hope this helps! :)
