Window: postMessage() メソッド - Web API | MDN
window.postMessage() は、 Window オブジェクト間で安全にオリジン間通信を可能にするためのメソッドです。例えば、ポップアップとそれを表示したページの間や、iframe とそれが埋め込まれたページの間での通信に使うことができます。 通常、異なった複数のページでのスクリプトはそれらが実行されたページが同じオリジンである場合に限りお互いにアクセスすることが可能です（「同一オリジンポリシー」とも呼ばれます）。正しく使用した window.postMessage はこの制限を安全に回避するための制御された仕組みを提供します。 さらに、アクセスするスクリプトは、アクセスする文書のウィンドウオブジェクトを事前に取得しておく必要があります。これは、ポップアップの場合は window.open()、iframe の場合は iframe.contentWindow などのメソッドを使

Jam – The JavaScript Package Manager - HotFrameworks
Hi guys, my name is Daniel, I am a huge fan of JamJS, unfortunately it seems the website that was a source of information and a home for it has disappeared. People like myself were huge fans so I set this up for us to have a home and a place of information. Below I was able to salvage some information from the original website. I am not involved with the project, I am just a fan so please do not c
Ember.js - A framework for ambitious web developers

Backbone.js
Backbone's only hard dependency is Underscore.js ( >= 1.8.3). For RESTful persistence and DOM manipulation with Backbone.View, include jQuery ( >= 1.11.0). (Mimics of the Underscore and jQuery APIs, such as Lodash and Zepto, will also tend to work, with varying degrees of compatibility.) Getting Started When working on a web application that involves a lot of JavaScript, one of the first things yo
JSX - a faster, safer, easier JavaScript
JSX is a statically-typed, object-oriented programming language designed to run on modern web browsers. Being developed at DeNA as a research project, the language has following characteristics. faster JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript. The gain may vary, but even the optimi

Handlebars
Semantic templatesHandlebars provides the power necessary to let you build semantic templates effectively with no frustration. Mustache-compatibleHandlebars is largely compatible with Mustache templates. In most cases it is possible to swap out Mustache with Handlebars and continue using your current templates. Fast executionHandlebars compiles templates into JavaScript functions. This makes the t
Jstdutil - A Ruby wrapper over JsTestDriver / JavaScript - cjohansen.no
Today I needed remote access to a gem I've been tinkering with for a while, so I pushed it to Gemcutter. It's called jstdutil, and it provides a small Ruby wrapper over JsTestDriver that adds colored output, a short, snappy `jstestdriver` command and autotest. Install it The gem is available on Gemcutter, which requires that you install their gem (and use RubyGems >= 1.3.5): gem update --system ge

Leon Casino Ελλάδας Leon Casino Ελλάδας άνοιξε πέρυσι στην Αθήνα, όταν παρέες με φραπέ στο χέρι ζητούσαν λίγη τρέλα στα φρουτάκια. Η αρχική έκδοση είχε απλούς κουλοχέρηδες και ρουλέτα, αλλά γρήγορα φούντωσε σαν σούπα στο τζάκι. Παίκτες από Θεσσαλονίκη, Πάτρα και Ηράκλειο μπήκαν στην πρίζα, δοκίμασαν ζωντανούς ντίλερ και σηκώθηκαν τρελοί με τζακ ποτ. Στην τωρινή φάση, Leon Casino Ελλάδας προσφέρει
CoffeeScript
CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can u
GitHub - mythz/jquip: jQuery in Parts
jQuery getting too big? The primary goal of this project would be for the feedback/demand to kickstart jquery.com into re-organizing its code-base so it's more modular since we believe we've proved the most useful parts of jQuery is a fraction of its code-base. To this end, follow this project if you want jquery.com to measure the demand for this. Another project with similar goals is http://ender
zepto.js — the aerogel-weight mobile javascript framework
Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto. While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting
Microjs: Fantastic Micro-Frameworks and Micro-Libraries for Fun and Profit!
Fantastic Micro-Frameworks and Micro-Libraries for Fun and Profit! How much library code do you really need — 50K? 100K? 150K? More? How much of that do you really use? Sure, we all love our favorite monolithic frameworks, and sometimes we even use them fully. But how often do we reach for the ride-on John Deere tractor with air conditioning and six-speaker sound system, when a judiciously applied

jasmine-headless-webkit -- The fastest way to run your Jasmine specs!
Jasmine Headless WebKit Run your Jasmine specs at sonic boom speed! Jasmine is great. I love it. But running Jasmine when you need to test code that will run in a browser environment can be problematic and slow: The Jasmine gem's server makes getting up and testing very fast, but F5-ing your browser for each test run is distracting. Jasmine CI uses Selenium, which speeds up the process a bit, but
