Angular2 include html from server into a div

I got a serie of html in my server. For example:

• http://docs.example.com/intro.html

• http://docs.example.com/page1.html

• http://docs.example.com/page2.html

And I trying to include those files into a<div> in my angular2 v4 app. For example:

component.ts

public changePage(name: string) {
  switch (name) {
    case 'intro': this.myHtmlTemplate = 'http://docs.example.com/intro.html'; break;
    case 'page1': this.myHtmlTemplate = 'http://docs.example.com/page1.html'; break;
    case 'page2': this.myHtmlTemplate = 'http://docs.example.com/page2.html'; break;
  }
}

component.html

<div [innerHtml]="myHtmlTemplate"></div>

but it doesnt work. I tried the following solutions:

Angular4 Load external html page in a div

Dynamically load HTML template in angular2

but it doesn't work for me. Can somebody help me with this problem please ?

Angular security Blocks dynamic rendering of HTML and other scripts. You need to bypass them using DOM Sanitizer.

Read more here : Angular Security

DO below changes in your code :

// in your component.ts file

//import this 
import { DomSanitizer } from '@angular/platform-browser';


// in constructor create object 

constructor( 
...
private sanitizer: DomSanitizer

...
){

}

someMethod(){

  const headers = new HttpHeaders({
  'Content-Type':  'text/plain',
});
const request = this.http.get<string>('https://developer.mozilla.org/en-US/docs/Learn/HTML/Forms/Your_first_HTML_form', {
  headers: headers,
  responseType: 'text'
}).subscribe(res => this.htmlString = res);

 this.htmlData = this.sanitizer.bypassSecurityTrustHtml(this.htmlString); // this line bypasses angular security

}

and in HTML file ;

<!-- In Your html file-->
    <div [innerHtml]="htmlData">
    </div>
