L'interactivité avec la balise HTML5 Canvas La balise <canvas> se comporte comme toute autre balise. Elle possède des attributs width, height et id. Le contenu de la balise correspond à un contenu alternatif pour les navigateurs ne la supportant pas. J'ai aussi défini une fonction à exécuter au chargement de la page et une balise <div> qui contiendra certaines informations, à savoir la quantité de mouvements effectués par l'élément. Le code JavaScript est un petit peu plus compliqué. var canvas, draw, width, height; var downcheck, upcheck, rightcheck, leftcheck; var up = 0;var down = 0;var left = 0;var right = 0; Ensuite, nous devrons créer une fonction init(), qui détermine ce qu'il faut faire au chargement de la page. function init() { canvas = document.getElementById('game'); height = canvas.height; width = canvas.width; draw = canvas.getContext('2d'); setInterval(redraw, 30); document.onkeydown = canvasMove; document.onkeyup = canvasStop; } Ensuite, nous devons ajouter une fonctionnalité pour déplacer le carré. Et voilà !
Developer Network edutopia Introducing computer programming to your kids can be a challenge, especially for those who aren’t familiar with the nuances of code. Fortunately, in the last few years, a number of apps, software, and guides have been produced that make the often-complex subject of computer coding easy to grasp for young learners. So where to begin? These are a few resources that parents can share with their kids to help them start learning about programming. Programming Tutorials From Made With Code by Google: Google's Made With Code project has a mission of encouraging girls to pursue careers in computer science. Inspiring Articles About Kids Learning to Code Still looking for some ideas? Coding Organizations for Kids For the non-coding parents, it can be difficult to know where to begin.
Creating an HTML5 Canvas Painting Application Table of contents Introduction My previous HTML5 Canvas tutorial provided you with insight into the numerous use cases for Canvas in web applications. In this article we will explore how you can write your own Canvas-based painting application. Making a web application that allows users to draw on a Canvas requires several important steps: setting up your HTML document with a Canvas context (a <canvas> element with an id), setting up your script to target that Canvas context and draw inside it and adding the required mouse event handlers for user interaction and associated logic. Once the event handlers are in place, it’s then fairly simple to add any desired functionality. The final painting application example looks like this: To make it easier to follow along with the code walkthrough presented below, you can download the full code example and follow along with it as you read the article. Getting started with the HTML We shall begin with a minimal HTML document: Canvas interaction Rectangle
Programming eBooks Programming iOS 11 If you're grounded in the basics of Swift, Xcode, and the Cocoa framework, this book provides a structured explanation of all essential real-world iOS app components. Through deep exploration and copious code examples, you'll learn how to create views, manipulate view controllers, and add features from iOS frameworks. Apprendre JavaScript : utilisation de la balise canvas I-A. JavaScript & ECMAScript▲ JavaScript (abrégé JS) est un langage de programmation de scripts principalement utilisé dans les pages Web interactives mais aussi côté serveur[1]. C'est un langage orienté objet à prototype, c'est-à-dire que les bases du langage et ses principales interfaces sont fournies par des objets qui ne sont pas des instances de classes, mais qui sont chacun équipés de constructeurs permettant de créer leurs propriétés, et notamment une propriété de prototypage qui permet d'en créer des objets héritiers personnalisés. Le langage a été créé en 1995 par Brendan Eich (Brendan Eich étant membre du conseil d'administration de la fondation Mozilla) pour le compte de Netscape Communications Corporation. Le langage, actuellement à la version 1.8.2, est une implémentation de la 3e version de la norme ECMA-262 qui intègre également des éléments inspirés du langage Python. En décembre 1995, Sun et Netscape annoncent la sortie de JavaScript. I-B. II-A. II-B. II-C. II-C-1. Note.
