Angular2 include html from server into a div

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

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>

Here is the working example of your requirement :

In your component first request pages with HTTP request 

this.http.get('http://docs.example.com/intro.html').map(response => response.text()).subscribe(html => Your_template = html);

use innerhtml with the safehtml pipe so your inline styling will be applied more info on GitHub page(https://gist.github.com/klihelp/4dcac910124409fa7bd20f230818c8d1)

<div [innerHtml]="Your_template | safeHtml"></div>

you have to get HTTP call to load HTML in plain text and load in div using innerHtml.

export class AppComponent implements OnInit {
name = 'Kissht';
KisshtHtml;
constructor(
 private http:HttpClient,
 private sanitizer:DomSanitizer){ }
ngOnInit(){
   this.http.get('https://kissht.com/', 
  {responseType:'text'}).subscribe(res=>{
    this.KisshtHtml = this.sanitizer.bypassSecurityTrustHtml(res);
  })
 }
}

Sometime you might get CORS issue in stackblitz whil loading external Html

This should do it:

First in your component.ts get the html with a http request:

import { Component, OnInit } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { map } from 'rxjs/operators'

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {

  constructor(private http: HttpClient) { }

  htmlString: string;

  ngOnInit() {
    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);
  }

}

And in your component.html simply use a one way data binding:

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

You actually want to display a page inside your angular app right?

For that you can add a iframe tag:

<iframe width="400" height="600" [src]="myHtmlTemplate"></iframe>
