GitHub - es-shims/es5-shim: ECMAScript 5 compatibility shims for legacy (and modern) JavaScript engines
es5-shim.js and es5-shim.min.js monkey-patch a JavaScript context to contain all EcmaScript 5 methods that can be faithfully emulated with a legacy JavaScript engine. Note: As es5-shim.js is designed to patch the native Javascript engine, it should be the library that is loaded first. es5-sham.js and es5-sham.min.js monkey-patch other ES5 methods as closely as possible. For these methods, as close

外道はるかぜちゃんジェネレータというWebアプリを いまどきな手法を用いて爆速で開発した話を紹介します。 先の3連休中、外道はるかぜちゃんジェネレータというWebアプリを開発&公開しました。ここで採用した開発手法がいまどきな爆速開発でしたのでちょっと紹介&ステマします。使った技術は以下の通りです。 AngularJS: Googleが開発しているViewModelなWeb開発ライブラリ(MVW: Model View Whateverだったかな?w) Github pages: スタティックサイトのホスティングに最適 Kii Cloud: mBaaS (mobile backend as a service) で共有データの保存に利用 HTML5 Canvas: 画像生成に。サーバサイドではなにもしてない! サービス概要 外道はるかぜちゃんジェネレータはベースとなる画像があり、そこに面白い
DailyJS: The Art of Error
Error was originally a character in the hit video game, "Zelda". I like to define a lot of objects that inherit from Error. I find it helps me to track down issues – post-mortem – but also to clearly handle expected errors. Sometimes writing error handling code feels like a chore, but it shouldn’t be an afterthought. Well-designed and well-tested errors will help you maintain projects, but also he
Using AngularJS Promises
In my previous article I discussed the benefits of using dependency injection to make code more testable and modular. In this article I’ll focus on using promises within an AngularJS application. This article assume some prior knowledge of promises (a good intro on promises and AngularJS' official documentation). Promises can be used to unnest asynchronous functions and allows one to chain multipl

Touche.js - seamless touch event mapping for your click eventsEffortlessly re-map click events to touch events on touchscreen UIs tl;dr Removes the 300ms delay (after the user lifts their finger), applied by all touchscreens devices and immediately invokes your click handlers. Takes your click events applied with jQuery and silently re-maps them to the "touchend" event for devices that support tou
jquery.pep.js | kinetic drag for mobile & desktop
jquery.pep.js is a lightweight jQuery plugin which turns any DOM element into a draggable object. It works across mostly all browsers, from old to new, from touch to click. I built it to serve a need in which jQuery UI’s draggable was not fulfilling, since it didn’t work on touch devices (without some hackery). All of Pep’s options are outlined on Github, so take a look. Feel free to email me with
Masato Kinugawa Security Blog: U+2028/2029とDOM based XSS
ECMAScriptの仕様では、0x0A/0x0D以外にU+2028/2029の文字も改行とすることが明記されています。 これはあまり知られていないように思います。 以下はアラートを出します。 <script> //[U+2028]alert(1) </script> 知られていないだけでなく、知っていたとしても、スクリプトで文字列を処理するときに、U+2028/2029まで考慮する開発者がどれだけいるのかという話です。 実際、U+2028/2029を放り込むと文字列リテラル内にその文字が生のまま配置され、エラーが出るページは本当にたくさんあります。まあ、エラーがでるだけなら、大抵の場合大きな問題にはなりません。 ところが、U+2028/2029によってXSSが引き起こされてしまう場合というのを最近実際に見ました。 Googleのサービスで見つけた2つのケースを取り上げたいと思います。 ケ
RequireJS

Dependency injection in JavaScript
I like the quote that the programming is all about managing complexity. Maybe you've heard that the computer world is a giant construction of abstractions. We simply wrap things and produce new tools over and over again. Just think for a minute. The languages which you use have build-in functionalities and they are probably abstracted functions of other low level operations. It's the same with Jav
AboutAcne
There are many dermatologists that recommend yogurt for acne. The reasoning is that, if you choose the right yogurt that contains probiotics, then it can fight the bad bacteria that is partly responsible for the cause of acne. Dermatologists obviously aren’t going to tell you to get those fake sugary yogurt substitutes with a bunch of chemicals, artificial sweeteners and corn syrup (why not just u
Tourist.js
Tweet Github Docs Tourist.js Simple, flexible tours brought to you by easel.io Tourist.js is a simple library for creating guided tours through your app. It's better suited to complex, single-page apps than websites. Our main requirement was the ability to control the interface for each step. For example, a step might need to open a window or menu, or wait for the user to complete a task. Tourist
Choosing a JavaScript MVC Framework
So you love the way single-page apps like Gmail and Trello feel, but aren’t sure where to start. Maybe your JavaScript code has become disorganized enough that you are convinced to try one of the numerous JavaScript MVC libraries/frameworks on your next project but aren’t sure which one to choose. I’m writing a book on single-page apps so I’ve pretty much “read the internet” on the topic. I’l
