How do I make a user's browser blink/flash/highlight in the task bar using JavaScript?

Edit: These users do want to be distracted when ...
Hello All: Apologies in advance for the appaling long post (and pretty applaing code, too). Taking Jeff Atwood's advice, I decided to use a JavaScript library for the very basic to-do list application I'm writing. I picked the Dojo toolkit, version 1.1.1.

Reading through this question on multi-threaded javascript, I was wondering if there would be any security implications in allowing javascript to spawn mutliple threads. For example, would there be a risk of a malicious script repeatedly spawning thread after thread in an attempt to overwhelm the operating system or interpreter and trig...

Hello. I have very strange problem. Under some elusive circumstances I fail to apply any jQuery selector on my pages under IE. It's OK under Firefox though. jQuery function simply returns empty array. Any suggestions? Page is too complex to post it here.

Does anyone know of a complete Ajax/PHP contact form that includes error handling/form validation and requires minimum effort to setup? It must also still function in cases where JavaScript is disabled. I'm pretty much looking for a plug and play solution (well, as close to it as possible). ...

Nowadays, it seems to be an animated spinning circle. (e.g., when you are loading a new tab in Firefox, or booting in Mac OS X. Coincidentally, the...
