1. Beware of class-only selectors
jQuery
A great part about using a JavaScript library like jQuery is its selectors. But before you use them all over the place, stop to think: what are the processing costs?
Basically, jQuery defines all the elements on a page as a huge JavaScript object, and then interacts with it. You don’t have to look into the source code to realize that the selector function works by iterating all objects that fit a certain criteria. Therefore, it makes sense to give the selection function a helping hand by defining the selection criteria more specifically.
Let’s do a quick case-study:
Pretend you’re doing site navigation and want to select an LI that has the CSS class ‘active.’ One way to select this element is:
$('.active')
This selector works just fine, but think about what the jQuery DOM traversal has to do here: iterating through hundreds of elements on the page, selecting any with the class ‘active.’ That’s a lot of processing for our little nav bar.
It turns out, according to selec
