只需简单地使用[innerHTML]属性在你的HTML，如下所示:

<div [innerHTML]="myVal"></div>

你的组件中是否有包含html标记或 需要在模板中显示的实体?传统的 插值不会工作，但是innerHTML属性绑定会 救援。

使用{{myVal}}不能正常工作!这不会拾取HTML标签，如<p>， <strong>等，只将其作为字符串传递…

假设你的组件中有这样的代码:

碰到弦!弦!弦!< /埃隆·马斯克>”

如果你使用{{myVal}}，你会在视图中得到这个:

<strong>Stackoverflow</strong> is <em>helpful!</em>

但是使用[innerHTML]="myVal"使结果像预期的那样:

Stackoverflow很有用!

正确的语法如下:

<div [innerHTML]="theHtmlString"></div>

文档参考

Angular 2.0.0和Angular 4.0.0 final

对于安全的内容

<div [innerHTML]="myVal"></div>

DOMSanitizer

潜在的不安全HTML需要使用angular的DOM杀毒器显式地标记为受信任，这样就不会剥离潜在的不安全内容

<div [innerHTML]="myVal | safeHtml"></div>

用一根管子

@Pipe({name: 'safeHtml'})
export class Safe {
  constructor(private sanitizer:DomSanitizer){}

  transform(style) {
    return this.sanitizer.bypassSecurityTrustHtml(style);
    //return this.sanitizer.bypassSecurityTrustStyle(style);
    // return this.sanitizer.bypassSecurityTrustXxx(style); - see docs
  }
}

在RC.1中，有些样式不能使用绑定语法添加

文档:https://angular.io/api/platform-browser/DomSanitizer

安全警告

相信用户添加的HTML可能会带来安全风险。之前提到的文档状态:

调用任意一个bypassSecurityTrust…api禁用Angular内置的对传入值的处理功能。仔细检查和审计进入此调用的所有值和代码路径。确保任何用户数据都为此安全上下文进行了适当的转义。更多详细信息请参见《安全指南》。

角标记

类似的

class FooComponent {
  bar = 'bar';
  foo = `<div>{{bar}}</div>
    <my-comp></my-comp>
    <input [(ngModel)]="bar">`;

with

<div [innerHTML]="foo"></div>

不会导致Angular在foo中处理任何特定于Angular的东西。 Angular在构建时用生成的代码替换Angular特定的标记。在运行时添加的标记不会被Angular处理。

要添加包含特定于angular的标记(属性或值绑定、组件、指令、管道等)的HTML，需要添加动态模块并在运行时编译组件。 如何在Angular 2.0中使用/创建动态模板来编译动态组件?

为了得到一个完整的答案，如果你的HTML内容是在一个组件变量中，你也可以使用:

<div [innerHTML]=componentVariableThatHasTheHtml></div>

在Angular v2.1.1中工作

<div [innerHTML]="variable or htmlString">
</div>

我已经建立下面的库，这将有助于重新绑定html格式的绑定。 请找到下面使用这个库的步骤。这个库基本上允许在AOT中注入JIT编译器代码
