For the jQuery fans out there, I posted a simple jQuery plugin a few weeks ago that adds $.slowEach() and $().slowEach() methods that are similar to this code and are compatible with jQuery’s normal $.each() and $().each():

I think this is what http://www.tumuski.com/code/clumpy/overview/ wraps into a nice library, with calls that resemble the usual flow control statements.

this is one of the oldest tricks in the book… been using it since at least 1999. Good for the newbies to learn it though.

Isn’t this what Prototype does with its Function.defer() method?

@V1: same here, though not 100 MB. 5 MB of drawing commands, rendered asynchronously. The user can interact with the drawing while it’s still being rendered (most important content rendered first).

Using the same technique in actionscript to process 100mb files with out losing UI responsiveness.

I don’t see any chunk processing there… it’s a one by one thing, so maybe that function should be simply called “asyncProcess”.

Also, there is a tendency on using small timeout values, like 100ms, to have stuff executed “immediately”. Forget about it… go ahead setting 0ms in all cases. It will just work as well, without that 100ms delay. Leave higher timeout values only if you really need them.

I used similar method to load points for a Google Map.

It’s a good method to avoid browser freeze.
From my investigation setting the timeout to a value smaller than 10ms will cause IE6 to freeze…
