"this" is useful for a lot of reasons, including the examples in this chapter: http://eloquentjavascript.net/chapter8.html This book is free, I'm not plugging it, have no interest in plugging it. Looks like you don't understand basic javascript, that's why I tried to point you into a direction that may help you. If you choose to ignore it, fine, but don't insult people. Also, you should post javascript questions in javascript mailing lists, not here.
