To create a component dynamicly. 1. Add a container with ref: @Component({ selector: 'app-root', template: ` <div> <div #entry> <!-- We want to create auth-form component inside this div--> </div> </div> ` }) 2. View this con…

本文所有内容以 Angular 2 Quick Start 项目为基础,使用 TypeScript 语言. 如上图,最近遇到一个需求,需要在一个刚启动的 Angular 2 项目中使用 snap.svg 操作页面上的 svg 元素做动画. 我粗略的看了下, snap.svg 的实现似乎并没有遵从什么模块规范,就是常见的提供几个全局变量完事.如果真的耿直的在 Component 中去用的话,会在执行 tsc 编译成 js 文件这一过程中报错. 这是因为 TypeScript 编译器并不知道 sna…

One thing that we can do is to add styles directly to HTML elements that live within our component. However, in this lesson we see that style classes added to your template HTML within your component get applied to an inner <div> and not your compon…

Angular has a very robust security model. Dynamically inserted html, style or url values into the DOM open up possibilities for attackers to compromise your site. Thus Angular treats all values as untrusted by default. In this lesson we learn how to…

如果你之前没有深入了解 Angular 依赖注入系统,那你现在可能认为 Angular 程序内的根注入器包含所有合并的服务提供商,每一个组件都有它自己的注入器,延迟加载模块有它自己的注入器. 但是,仅仅知道这些可能还不够呢? 不久前有个叫 Tree-Shakeable Tokens feature 被合并到 master 分支,如果你和我一样充满好奇心,可能也想知道这个 feature 改变了哪些东西. 所以现在去看看,可能有意外收获嗷. 注入器树(Injector Tree) 大多数开发者知道…

更新 : 2018-01-30 ng 的 overlap 在关闭的时候对 backdrop 做了一个 style pointer 目的是让 backdrop 不被 2 次点击, 但是呢,  css pointerEvent 'none' 也有一个穿透的效果,就是说, backdrop 还没完全关上时, 其后面的按钮是可以被点击到的. 这个需要注意,因为可能你并不想这样. 另外一个要说的是, overlap 是可以打开多个的. 通过多个 overlapRef 去自行做管理. 所以请把 overla…
