Scrimba is a new way of teaching and learning how to code. We call it interactive code screencasts. Here’s why it's a great way of learning.

Dans ce deuxième chapitre consacré aux regex, nous allons voir leur utilisation au sein du JavaScript. En effet, le premier chapitre n'était là que pour enseigner la base de la syntaxe alors que, une fois couplées à un langage de programmation, les regex deviennent très utiles. En JavaScript, elles utilisent l'objet RegExp et permettent de faire tout ce que l'on attend d'une regex : rechercher un terme, le capturer, le remplacer, etc.

Première question : qu’est-ce qu’un préprocesseur ? Un préprocesseur est un programme qui procède à des transformations sur un code source, avant l’étape de traduction proprement dite (compilation ou interprétation). source Wikipedia. Dans le cas d’un préprocesseur CSS la syntaxe simplifiée ou enrichie en entrée est analysée et compilée en un langage que nous connaissons tous et que nous utilisons au quotidien : CSS.

in this JSON tutorial and guide, I’m attempting to provide a fairly comprehensive discussion of JSON, its history, and its usefulness. I’ll close with a list of some practical JSON tools that might come in handy in future projects. JSON Defined JSON stands for JavaScript Object Notation and it’s a data format. That is, it’s a way to hold bits of information, similar to a database. Although JSON originated outside the ECMAScript specification, it is now closely related to JavaScript with the spec now including a JSON object and many developers incorporating it as a quasi-subset of the language.

I think there are many developers who don’t realize that most of the jQuery methods they use have native equivalents that require the same or only a slighter larger amount of code to use. Below are a series of code samples showing some popular jQuery functions along with their native counterparts.

You can make MPIV work with more sites by adding your own host rules. You don't need to edit the source code for this. Instead, you paste the rule into MPIV's settings dialog which is accessible from your script manager's toolbar icon menu, e g. "User Script Commands" → "Set up Mouseover Popup Image Viewer" for Greasemonkey users.

Attention cependant, les navigateurs ne permettent pas de jeter des valeurs arbitrairement grandes sur eux. Ils ont des limites. Dépasser cette limite et les colonnes se développeront à la valeur padding-bottom et vous finirez avec de très longues pages. Heureusement, nous connaissons cette limite (par Safari; le plus conservateur à ce sujet): 32767px. Cela devrait suffire pour la plupart des cas (se sentir si libre d'utiliser une valeur inférieure) et des rendements nous code comme ceci: # Block_1, # block_2, # block_3 { padding-bottom: 32767px; margin-bottom:-32767px; } # Wrapper { overflow: hidden; }

calc() is a native CSS way to do simple math right in CSS as a replacement for any length value (or pretty much any number value). It has four simple math operators: add (+), subtract (-), multiply (*), and divide (/). Being able to do math in code is nice and a welcome addition to a language that is fairly number heavy. But is it useful? I've strained my brain in the past trying to think of obviously useful cases. There definitely are some though.

REGEX qui est une contraction de l'anglais Regular expression traduit en français par Expressions régulières, mais aussi Expressions rationnelles Qu'est ce qu'une expression régulière ? TROUVER (retrouver ==> coupler ==> assortir) des MOTIFS (pattern ==> profils ==> masques ==> structures) et de TRAITER (récupérer ==> extraire ==> remplacer) des éléments à l'intérieur d'un chaîne de caractères. On commence par déterminer le motif de ce que l'on cherche avant d'en appliquer le traitement souhaité grâce aux fonctions fournies par PHP. # Pour vous aider dans la compréhension de ce formidable outil, le cours sera agrémenté, Qu'est ce que je peux faire avec une expression régulière ? On peut tout faire avec une expression régulière... rien ne semble impossible en effet !.

I have a Greasemonkey script that works just fine in Firefox and Opera. I struggle with getting it to work in Chrome, however. The problem is injecting a function into the page that can be invoked by code from the page. Here's what I'm doing so far: First, I get a helper reference to the unsafeWindow for Firefox. This allows me to have the same code for FF and Opera (and Chrome, I thought).

These tools and utilities have regular expressions as the core of their functionality. grep - The utility from the UNIX world that first made regular expressions popular PowerGREP - Next generation grep for Microsoft Windows RegexBuddy - Learn, create, understand, test, use and save regular expressions. RegexBuddy makes working with regular expressions easier than ever before. General Applications with Notable Support for Regular Expressions There are a lot of applications these days that support regular expressions in one way or another, enhancing certain part of their functionality. But certain applications stand out from the crowd by implementing a full-featured Perl-style regular expression flavor and allowing regular expressions to be used instead of literal search terms throughout the application. EditPad Pro - Convenient text editor with a powerful regex-based search and replace feature, as well as regex-based customizable syntax coloring.
