Why is jQuery so widely adopted versus other Javascript frameworks?

I manage a group of programmers. I do value my employees opinion but lately we've been divided as to which framework to use on web projects. I personally favor MooTools , but some of my team seems to want to migrate to jQuery because it is more widely adopted. That by itself is not enough for me to allow a migration. I have used both jQuery and MooTools . This particular essay tends to

为什么jQuery如此广泛地被采用与其他Javascript框架?

我管理一群程序员。 我非常重视员工的意见,但最近我们对于在网络项目中使用哪种框架感到分歧。 我个人喜欢MooTools ,但我的一些团队似乎想迁移到jQuery,因为它被更广泛地采用。 这本身不足以让我进行移民。 我用过jQuery和MooTools 。 这篇特别的文章倾向于反映我对这两个框架的感受。 jQuery非常适合DOM操作,但似乎仅限于帮助您实现这一点。 特性明智的是, jQuery和MooTools都支持简单的DOM选择和操作 : // jQu

Do es6 template literals protect against sql injection?

Do es6 template literals, when used to construct queries, protect against SQL injection? Can you provide some examples of common attacks and how they would be mitigated? More specifically, I plan to use the mssql module in a node project. In their documentation under the template literals section it says "All values are automatically sanitized against SQL injection". Is this true p

es6模板文字是否可以防止sql注入?

es6模板文字在用于构建查询时防止SQL注入? 你能提供一些常见攻击的例子,以及它们将如何缓解? 更具体地说,我打算在节点项目中使用mssql模块。 在模板文字部分的文档中,它说“所有的值都会自动对SQL注入进行清理”。 这纯粹是因为ES6模板文字是如何工作的吗? 不,ES6模板文字只是构建字符串的另一种方式,如果要使用它们从所提供的用户输入构建原始SQL查询而不进行其他过滤/转义,则不会保护您免受SQL注入的影响: let na

Are PDO prepared statements enough

This question already has an answer here: Are PDO prepared statements sufficient to prevent SQL injection? 7 answers There's actually three concerns here, each of which requires a different approach.

What is the difference between SystemJS and CommonJS

I see there are article explaining difference between commonJs and AMD but I am unable to relate between commonJS and SystemJS. Both of these are used in AngularJS 2 development. As both of these are module loader then why do we require both? CommonJS is used in NodeJS to require modules at build time. Eg the modules are compiled and are then delivered to the browser with all code loaded up

SystemJS和CommonJS有什么区别

我看到有文章解释commonJs和AMD之间的差异,但我无法将commonJS和SystemJS联系起来。 这两个都用于AngularJS 2开发。 由于这两个都是模块加载器,那么为什么我们都需要? CommonJS用于NodeJS在构建时需要模块。 例如,模块被编译,然后将所有代码预先加载到浏览器中。 但是SystemJS取代了requireJS。 SystemJS在运行时动态加载模块。 在Angular2中,如果你看着你的浏览器的NET选项卡,当你浏览更多的应用程序时,你会看

Why does my grunt

I am trying to get up and running with the grunt-contrib-requirejs task. Being new to RequireJS in general and having never used the optimizer/r.js, I am really confused how to get this to work. As a start, I have set up a simple directory structure like this: root ├── js │ ├── helper │ │ ├── a.js │ │ ├── b.js │ │ └── d-dep.js │ └── main.js ├── node_modules │ └── [dependenc

为什么我的咕噜声

我正在尝试用grunt-contrib-requirejs任务启动并运行。 作为RequireJS的新手,从未使用优化器/ r.js,我真的很困惑如何让这个工作。 首先,我设置了一个简单的目录结构,如下所示: root ├── js │ ├── helper │ │ ├── a.js │ │ ├── b.js │ │ └── d-dep.js │ └── main.js ├── node_modules │ └── [dependencies from package.json] ├── Gruntfile.js └── package.json 我已经在浏览器中测试过它,并且所

Grunt requirejs nested dependencies

Grunt build successful but requirejs dependent libraries unavailable

Problem I have a grunt build that completes successfully and most libraries are available except for those dependent on other libraries. Example For example, underscore-string depends on underscore and attaches itself to the underscore namespace as _.string but that function isn't available in the app. This is the same problem I have with moment.range. RequireJS Config { "name": "a

Grunt构建成功,但requirejs相关库不可用

问题 我有一个成功完成的grunt构建,除了依赖于其他库的那些库之外,大多数库都可用。 例 例如,underscore-string依赖于下划线,并将其自身作为_.string附加到下划线名称空间,但该功能在应用程序中不可用。 这与我遇到同样的问题。 RequireJS配置 { "name": "app", "dir": "client-compress", "baseUrl": "client-dist", "preserveLicenseComments": true, "paths": { "underscore": "bower_components/u
