jQuery Optimizations

I've just come to the end of a large development project. We were on a tight timeline, so a lot o开发者_StackOverflowf optimization was "deferred". Now that we met our deadline, we're going back and trying to optimize things.

My questions is this: What are some of the most important things you look for when optimizing jQuery web sites. Alternately I'd love to hear of sites/lists that have particularly good advise for optimizing jQuery.

I've already read a few articles, http://www.tvidesign.co.uk/blog/improve-your-jquery-25-excellent-tips.aspx was an especially good read.

mostly i look at selectors that repeat themselfs.. most of the times these can be saved into a variable and used over and over, for example:

$('.some_class').doSomthing();
$('.some_class').doSomethingElse();

can be turned into:

selectedItems = $('.some_class');
selectedItems.doSomething(); selectedItems.doSomethingElse();

this way the selector goes over the DOM once... then you can continue to use the variable as a jquery object thanks to the fact that every jquery method returns the jquery object.

Just one tip out of many out there...
