jQuery selectors and attribute selectors reference and examples

jQuery selectors and attribute selectors are some of the best features jQuery has to offer when it comes to DOM manipulation. Read this article to view a full table with examples.

The following table lists the different methods you have available to you to select nodes when using jQuery. All of the listed selectors should be wrapped in the following to stop your jQuery scripts conflicting with other libraries:

This post is based on a chapter from Even Faster Web Sites, the follow-up to High Performance Web Sites. Posts in this series include: chapters and contributing authors, Splitting the Initial Payload, Loading Scripts Without Blocking, Coupling Asynchronous Scripts, Positioning Inline Scripts, Sharding Dominant Domains, Flushing the Document Early, Using Iframes Sparingly, and Simplifying CSS Selectors. “Simplifying CSS Selectors” is the last chapter in my next book. My investigation into CSS selector performance is therefore fairly recent. A few months ago, I wrote a blog post about the Performance Impact of CSS Selectors. It talks about the different types of CSS selectors, which ones are hypothesized to be the most painful, and how the impact of selector matching might be overestimated. It concludes with this hypothesis:

[Browsers read CSS selectors from right to left, therefore...] The key to optimizing CSS selectors is to focus on the rightmost selector, also called the key selector (coincidence?). Here’s a much more expensive selector: A.class0007 * {}. Although this selector might look simpler, it’s more expensive for the browser to match. Because the browser moves right to left, it starts by checking all the elements that match the key selector, “*“. This means the browser must try to match this selector against all elements in the page.

A Look at Some of the New Selectors Introduced in CSS3

By now I’m sure you have grasped at least the basics and simplicity of the jQuery library. Now it’s time to move on to some more in depth and practical techniques. jQuery isn’t just for hiding and showing content as we saw in the first part of our series, it can also perform many powerful tasks for us with just a few lines of code. For part two of our jQuery series, we will have a look at some special selectors, the animation method, and simple AJAX calls. Be sure to check out the demo for each section for an idea of how you could implement some of these ideas and scripts! Special Selectors We have learned that selecting elements with jQuery is very similar to selecting elements with CSS. For example, say we wanted to select all paragraphs within a certain div, we could do something like this: $(function(){ $('#my_div p').click(function(){ //your code here }); }); This is all fine and dandy for simple selections and manipulation. But what if we wanted to get more specific or use a

ie-css3.js allows Internet Explorer to identify CSS3 pseudo selectors and render any style rules defined with them. Simply include the script in your pages and start using these selectors in your style sheets — they'll work in IE... Honest...!

Forgotten CSS selectors

Well, the market share of IE 6 is now finally at a level where we as developers can say that a site “supporting” IE 6 does not mean “looking pixel perfect”. Fortunately more and more clients understand this as well. IE 7 has been out for well over three years and IE 9 is on the horizon, so I think it’s time to revive those CSS selectors that you never got to use just because IE 6 doesn’t understand them.
