Execute Background Task In Javascript

Question

I have a cpu intensive task that I need to run on the client. Ideally, I\'d like to be able to invoke the function and trigger progress events using jquery so I can update

Great answer Kevin! I wrote something similar a few years back, though less sophisticated. Source code is here if anyone wants it:

Anything with a run() method can be queued as a task. Tasks can re-queue themselves to perform work in chunks. You can prioritize tasks, add/remove them at will, pause / resume the entire queue, etc. Works well with asynchronous operations - my original use for this was to manage several concurrent XMLHttpRequests.

Basic usage is pretty simple:

var taskQueue = new TaskQueue();
taskQueue.schedule("alert('hello there')");

The header comments in the .js file provide more advanced examples.
