Native HTML5 Drag and Drop Introduction For years, we've been using libraries like JQuery and Dojo to simplify complex UI elements like animations, rounded corners, and drag and drop. There's no doubt, eye-candy is important for making rich, immersive experiences on the web. Drag and drop (DnD) is a first class citizen in HTML5! Feature Detection Many apps that utilize DnD would have a poor experience without it. If you need to rely on an API, always use feature detection rather than sniffing the browser's User-Agent. if (Modernizr.draganddrop) { // Browser supports HTML5 DnD. } else { // Fallback to a library solution. } Creating draggable content Making an object draggable is simple. As an example, let's start creating rearrangeable columns. <div id="columns"><div class="column" draggable="true"><header>A</header></div><div class="column" draggable="true"><header>B</header></div><div class="column" draggable="true"><header>C</header></div></div> Result (draggable but won't do anything): Listening for Dragging Events

Javascript in Modern Web Design In today's web design, Javascript is a must-have component. Aside from its functionality, Javascript can enhance user experience by creating transitional effects such as fading and sliding animation. Thanks to the open source Javascript frameworks, we don't need to write custom Javascript from scratch anymore. Here are 47 Javascript plugins that you can use to enhance the user experience and functionality of your website. The Two Popular Javascript Frameworks Right now, the two commonly used Javascript frameworks are: jQuery and MooTools. Loading ... Image Zoom and Popup Lightbox You're probably very familiar with Lightbox — a light Javascript used to display overlay images on the current page. jQuery lightBox Plugin This is exactly the same as Lightbox JS, but written on top of jQuery library. Thickbox Thickbox is a jQuery plugin that is very similar to Lightbox, but comes with more features. Note: Web Designer Wall uses Thickbox to display the gallery images and tutorial demos.

Top 8 JavaScript Projects You May Not Know Last year's article 10 Experimental PHP Projects Pushing the Envelope and its followup 9 More Experimental PHP Projects You Should Check Out struck such a chord with developers that I thought it would be fun to continue the theme, this time applying the idea to the JavaScript programming language. Perhaps more than any other programming language in history, JavaScript is experiencing a major renaissance thanks to its unique ability to serve as the glue between the client- and server-sides of a web application, a trait which is quickly becoming indispensable as developers seek to create highly responsive features which closely mimic their desktop-bound brethren. Given so much attention, we're seeing incredible innovation in the JavaScript space, and with it a fair amount of experimentation. In this article I'll highlight ten crazy JavaScript experiments, some of which are already changing the language in profound ways.

New Adventures in Software » More Stupid Java Tricks My previous post was reasonably popular so I decided to follow-up with some more stupid Java tricks. It should go without saying that you shouldn’t use these techniques in any serious code, unless of course your objective is to write unmaintainable code. It was pointed out to me by a couple of people that the puzzle I posed previously is also in Josh Bloch and Neal Gafter’s excellent Java Puzzlers book. If you are interested in all of the ugly corners of the Java platform, this book is well worth buying. Unchecked Checked Exceptions Throw checked exceptions without the hassle of dealing with them There’s a lot of debate about the relative merits of checked and unchecked exceptions in Java. The slightly more socially-acceptable Class.newInstance() method is another way. Note that this method propagates any exception thrown by the nullary constructor, including a checked exception. Invasion of Privacy Strings aren’t really immutable, even literals can’t be trusted then this prints this Any more?

JavaScript JavaScript (JS) is a lightweight interpreted or JIT-compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. This section is dedicated to the JavaScript language itself, and not the parts that are specific to Web pages or other host environments. The standard for JavaScript is ECMAScript. Tutorials Learn how to program in JavaScript with guides and tutorials. For complete beginners Head over to our Learning Area JavaScript topic if you want to learn JavaScript but have no previous experience of JavaScript or programming. JavaScript first steps Answers some fundamental questions such as "what is JavaScript?" JavaScript building blocks Introducing JavaScript objects Closures

Javascript Tutorial In this lesson, we'll learn about the core functionality of the JavaScript language. Lesson Goals To work with the HTML DOM.To follow JavaScript syntax rules.To write JavaScript inline.To write JavaScript in script blocks.To create and link to external JavaScript files.To work with JavaScript objects, methods, and properties.To reference HTML elements with JavaScript.To use event handlers. In this course, we refer to the language we are learning as JavaScript, which is what it is usually called. However, JavaScript was invented by Netscape Communications and is now owned by Oracle Corporation. The HTML Document Object Model (DOM) is the browser's view of an HTML page as an object hierarchy, starting with the browser window itself and moving deeper into the page, including all of the elements on the page and their attributes. As shown, the top-level object is window. Basic Rules JavaScript statements end with semi-colons. Dot Notation A document can have multiple form elements as children.

harmony:specification_drafts This page contains a historical record of working draft of the specification prepared by the project editor. Errors in the current draft should be reported as bugs at Report the version you are reading, and an appropriate “component” (editorial issues, technical issues, etc.). Such bug reports are particularly useful for specific bugs such as misspellings or errors in algorithms. An unofficial HTML version of the Edition 6 working draft is usually available at For now, all draft found here are snapshots taken of the project editor’s working draft. It is reasonable to assume that the editor is aware of the major inconsistencies or missing material, but you can’t over report. The rationale for design decisions, are not generally part of the specification. The primary target audience of this specification is implementors who must create highly interoperable ECMAScript implementations. Changes include:

Javascript is an easy-to-use programming language that can be embedded in the header of your web pages. What's the difference between JavaScript and Java? Actually, the 2 languages have almost nothing in common except for the name. What is Object Oriented Programming? Everyone that wants to program JavaScript should at least try reading the following section. Object-oriented programming consists of Objects, Methods and Properties. The directly accessible bits of information in the object are its properties. Objects and Properties Methods

Clase Date en Javascript Explicamos la clase que se utiliza en Javascript para el manejo de fechas y horas, comentando sus métodos y propiedades. Vamos a empezar a relatar todas las cosas que debes saber sobre otro de los objetos nativos de Javascript, el que implementa la clase Date. Sobre la clase Date recae todo el trabajo con fechas en Javascript, como obtener una fecha, el día la hora actuales y otras cosas. Para trabajar con fechas necesitamos instanciar un objeto de la clase Date y con él ya podemos realizar las operaciones que necesitemos. Un objeto de la clase Date se puede crear de dos maneras distintas. Por un lado podemos crear el objeto con el día y hora actuales y por otro podemos crearlo con un día y hora distintos a los actuales. Para crear un objeto fecha con el día y hora actuales colocamos los paréntesis vacíos al llamar al constructor de la clase Date. miFecha = new Date() miFecha = new Date(año,mes,dia,hora,minutos,segundos) miFecha = new Date(año,mes,dia) getDate() Devuelve el día del mes.
