When upgrading from version 2.x to 3.x it’s important to use version 3 CSS and .png files. Version 3 is backwards compatible but it’s also a huge overhaul. One significant change is that you don’t need to call the update method manually (the script does it automatically). For more info see changelog. Version 2 is still maintained and updated here.

jQuery outside events: Why trigger an event on something, when you can trigger it on everything else? With jQuery outside events you can bind to an event that will be triggered only when a specific “originating” event occurs outside the element in question. For example, you can click outside, double-click outside, mouse-over outside, focus outside (and over ten more default “outside” events). Also
Addy Osmani explores several time-saving design patterns and best practices that can be employed to improve your plugin development process. (Note: this post is targeted at intermediate to advanced developers.) I occasionally write about implementing design patterns in JavaScript. They’re an excellent way of building upon proven approaches to solving common development problems, and I think there’

Range inputs in HTML are like this: <input type="range" name="quantity" min="1" max="10"> In browsers that support them, they look like this: Now that’s great and all. You could use it for anything where you want to collect a number from a user that has an enforced minimum and maximum value. But notice anything weird? All by itself, that range input doesn’t communicate to the user what number they
身近なところで話題になったので。 過去にも、「empty() とか remove() するより、DOMオブジェクトにアクセスして innerHTML = ”” した方が速いよ！」というブログエントリを投下する方が多かったのですが、「必ずAPIを使う」こと。 理由は、「メモリリークの温床だから」 GitHub で manipulation.js のソース読めば判るとおり、結構頻繁に jQuery.cleanData() が実行されてます。― jQuery.cleanData() メソッドは、data() API として独自に実装された「各要素と紐づけられるキー・バリューストア（メモリストア）」に対する処理なので、innerHTML を使う場合でも、jQuery.cleanData() を使うなら、まぁ問題無いです。 要するに、jQuery （Zeptoみたいな類似ライブラリもそう）は、常にH

Breaking down Amazon's mega dropdown
The hover effects on Amazon’s big ‘ole “Shop by Department” mega dropdown are super fast. Look'it how quick each submenu fills in as your mouse moves down the list: It’s instant. I got nerd sniped by this. Most dropdown menus have to include a bit of a delay when activating submenus. Here’s an old Khan Academy dropdown as an example: See the delay? You need that, because otherwise when you try to

The .on() method attaches event handlers to the currently selected set of elements in the jQuery object. As of jQuery 1.7, the .on() method provides all functionality required for attaching event handlers. For help in converting from older jQuery event methods, see .bind(), .delegate(), and .live(). To remove events bound with .on(), see .off(). To attach an event that runs only once and then remo
