coolio!

This has win baked in.

SelectorGadget is an open source bookmarklet that makes CSS selector generation and discovery on complicated sites a breeze. Just drag the bookmarklet to your bookmark bar, then go to any page and press it. A box will open in the bottom right of the website. Click on a page element that you would like your selector to match (it will turn green). SelectorGadget will then generate a minimal CSS selector for that element, and will highlight (yellow) everything that is matched by the selector. Now click on a highlighted element to remove it from the selector (red), or click on an unhighlighted element to add it to the selector. Through this process of selection and rejection, SelectorGadget helps you come up with the perfect CSS selector for your needs.

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.

This page lists down all the jQuery APIs at one place for your easy access. So my recommendation is to bookmark for future use.

The jQuery OpenID Plugin is a free plugin to add easy login support for the most popular OpenID RP's such as Google, Yahoo, AOL, and more. The inspiration for this plugin is based on openid-selector, openid-realselector, and ID Selector. This selector is different because it does not hide the markup details in javascript. Therefore, you can easily add new providers or rearrange the existing ones without digging into the javascript. The login form will still work for normal OpenID logins if javascript is disabled (see screenshot). jQueryOpenIdPlugin The plugin defaults to the first provider in the list which in the above case is a normal OpenID login box. There are two other types of providers, direct providers and username providers. A direct provider does not require any input and will automatically direct you to the provider login page. A user provider assists in building your OpenID URL. For example, Google and Yahoo are direct providers and AOL is a username provider tha
