如何在ionic2中加载外部html页面 [英] How to load external html page in ionic2

问题描述

我正在创建一个Ionic2应用程序。我有一个组件，我想将外部templateUrl加载到ex（http：www.example.com/test-view.html）。

I am creating an Ionic2 app. I have a component that I would like to load an external templateUrl into e.x (http:www.example.com/test-view.html).

我该如何去关于将html加载到@Component中的templateUrl变量中？

How do I go about loading that html into the templateUrl variable in @Component?

这是我到目前为止所做的。

Here's what I have so far.

import { Component, DynamicComponentLoader, ViewContainerRef,
    ViewChild } from '@angular/core';
import { bootstrap } from '@angular/platform-browser-dynamic';
import { Http, Headers, RequestOptions } from '@angular/http';


@Component({
    //templateUrl: 'build/pages/hello-ionic/hello-ionic.html'
    template: `<div [innerHTML]="myVal"></div>`,
    selector: 'HelloIonicPage'
})
export class HelloIonicPage {

    myVal: any;
    viewLink: any;
    viewHtml: any;

    constructor(private http: Http) {


        let headers = new Headers({ 'Content-Type': 'text/html' });
        let options = new RequestOptions({ headers: headers });

        this.viewHtml = this.http.get('http://example.net//test-view1.html');

        this.myVal = this.viewLink
        console.log(this.myVal);
    }
}

推荐答案

你可以这样做：

this.http
  .get('http://example.net//test-view1.html')
  .map(response => response.text())
  .subscribe(html => myVal = html);

请注意，html将被清理，所以如果你需要一些奇特的东西，你将不得不使用 DomSanitizationService 。不要忘记文档中的安全风险标志（;

Note that html will be sanitized, so if you need something fancy you'll have to use DomSanitizationService. Don't forget about it's Security Risk flag in the docs (;
