I remember my first programming class. I was seven. For the life of me, I could not make that damn turtle draw a star while playing music at the same time to save my life (or my grade). This is generally just as painful and traumatic to do in Javascript as it is in Logo.

The thing that makes Scriptaculous totally amazing is native simultaneous effects. Meaning, you can do a shape tween and an opacity change all at the same time, no jerkiness or anything. You can just pass in an array of effects to render, and it does them all at the same time.

So I’ve been playing with Scriptaculous a bit, and doing some debugging. I have a table, in which certain rows would should appear when a link is clicked. I’ve got it set with a display:none by default and I’m using Effect.SlideDown to have it appear.

IE tends to do some funny things with its security settings. In particular, if your settings are high enough, window.close() will throw a warning or silently stop working entirely.

window.opener = window;
window.close();

That’s all there is too it! Happy coding!
