jQuery nice plugin - sort of a little like the "nice" command, (http://en.wikipedia.org/wiki/Nice_(Unix)), (well, the overall idea is the same), but for jQuery iteration instead.
Usage: (just like jQuery .each, only slower, and probably won't hang your browser if you do something really silly (DOM intensive)
$('div').nice(function(idx,ele) {
for(var x = 0; x < 1000; x += 1) {
$(this).find('span').html('<div>Updated DOM</div>');
}
});
Imagine: you had a page with a giant DOM - the above would allow you to run without getting the dreaded "Unresponsive script" message... well, in most cases anyway - you can still do things to break it if you try - ie: each 100 iterations takes more than the amount of seconds before a timeout occurs.
Note: you can also set the iteration count if 100 is not enough before it clears the rendering queue, for example:
$.fn.nice.maxCount = 50;
Will clear the rendering queue when you reach 50 iterations
