In: Columns > Behind the Curtain By Jonathan Snook Published on September 18, 2006 When I first began programming with JavaScript, I created my variables and then encapsulated any functionality I needed to reuse into a function. In JavaScript, a function is an object; creating a function creates an object. As scripts get larger, functions become more interrelated.
In a true object-oriented sense, an object represents a thing. The important idea here is simply that objects encapsulate related functionality. In JavaScript, we often perform a series of tasks on existing objects. We’ve established that objects are good and useful, but how do we go about creating them? Using the object literalusing the new keyword with a function Let’s shed some light on these options, and the advantages and disadvantages of each. Using the Object Literal Creating a new object using the object literal syntax is very straightforward. Example: Creating Objects Prototype. Speed Up Your Javascript Load Time. Javascript is becoming increasingly popular on websites, from loading dynamic data via AJAX to adding special effects to your page.
Unfortunately, these features come at a price: you must often rely on heavy Javascript libraries that can add dozens or even hundreds of kilobytes to your page. Users hate waiting, so here are a few techniques you can use to trim down your sites. (Check out part 2 for downloadable examples.)

Carte de visite web 2.0. Anatomy of a Drag and Drop. The mechanics of a drag and drop are pretty interesting and most library implementations do similar things, albeit to various extents. As I explain the inner workings, I'll touch on Yahoo's, Mootools', and Script.aculo.us' implementations, what to expect, and how they differ.
A drag and drop essentially consists of a few events (and by events, I mean, moments in time, not DOM events). There's the moment a drag is started, there's the continuous dragging of an item, and finally there's the moment the item is no longer being dragged (ie: the drop). The items being dragged are sometimes referred to as draggables. On top of these events, there is also the interaction with other elements on the page; dragging over and out of an element and whether the dragged element has been dropped on top of another element on the page. The elements upon which draggable items are dropped onto are sometimes referred to as droppables. Starting the Drag Alternatively, this could be attached to a drag handle. Ajax Patterns. Ajax Lessons. 45 applications web 2.0 françaises. Avant la conférence LeWeb3 qui aura lieu en début de semaine prochaine à Paris, je me suis dit qu’il serait intéressant de lister les principaux acteurs français de cette nouvelle vague de sites web 2.0.
On se focalise souvent sur les startups américaines, mais il y a chez nous des jeunes pousses qui planchent actuellement sur des applications et des services web tous aussi prometteurs. Il y a une dynamique incroyable en ce moment, personne ne peut le nier. D’ailleurs pourquoi commence-t-on à parler de bulle 2.0 (en référence à la crise de 2000 qui a suivit l’avènement des premières startups) ?
C’est bien que le secteur du business Internet est en effervescence. D’ailleurs, si vous voulez découvrir plus en détail ce que revêt ce terme, je vous conseille ce site. Voici donc une liste (certainement pas exhaustive, mais je vous invite à mes laisser des commentaires afin de la compléter) d’applications web 2.0 conçues par des français.
