Angular 2无法正确解析html代码

尝试使用InnerHTML属性来尝试HTML代码以查看所得的HTML，但是如下示例所示，事实并非如此。 HTML代码被视为HTML标签，而不是创建元素，而是将它们作为简单的文本呈现。

@Component({
  selector: 'my-app',
  template: `
  <span [innerHTML]='working'> </span>
   <span [innerHTML]='notWorking'> </span>
  `
})
class AppComponent {  
  working="<h1>hello world angular 6</h1>";
  notWorking='&lt;p&gt; Random Text &lt;/p&gt;'
  constructor() {
    // TODO: Define your Angular component implementation
  }
}

Trying to HTML code to view the resulting HTML using the innerHTML property, but as you can see in the example below, it doesn't. The HTML code is viewed as the HTML tags and only, instead of creating the elements it renders them as simple text.

@Component({
  selector: 'my-app',
  template: `
  <span [innerHTML]='working'> </span>
   <span [innerHTML]='notWorking'> </span>
  `
})
class AppComponent {  
  working="<h1>hello world angular 6</h1>";
  notWorking='<p> Random Text </p>'
  constructor() {
    // TODO: Define your Angular component implementation
  }
}

一个想法可以是使用 domparser （示例）将 notWorking 字符串解析为有效的 html，然后将其注入innerHTML

https://codepen.io/jeremy-denis/pen/rNpZKzO?editors=1111

const { Component, VERSION } = ng.core;

@Component({
  selector: 'my-app',
  template: `
  <span [innerHTML]='working'> </span>
   <span [innerHTML]='notWorking'> </span>
  `
})
class AppComponent {  
  working="<h1>hello world angular 6</h1>";
  notWorking='<p> Random Text </p>'
  constructor() { 
    this.notWorking =  new DOMParser().parseFromString(this.notWorking, 'text/html').body.innerText;
  }
}

an idea can be to parse the notWorking string into valid html with domparser (for sample) before inject it in innerHTML

https://codepen.io/jeremy-denis/pen/rNpZKzO?editors=1111

const { Component, VERSION } = ng.core;

@Component({
  selector: 'my-app',
  template: `
  <span [innerHTML]='working'> </span>
   <span [innerHTML]='notWorking'> </span>
  `
})
class AppComponent {  
  working="<h1>hello world angular 6</h1>";
  notWorking='<p> Random Text </p>'
  constructor() { 
    this.notWorking =  new DOMParser().parseFromString(this.notWorking, 'text/html').body.innerText;
  }
}
