angular - 如何将 Angular2 组件渲染为字符串？

Question

我希望在构建 Google Maps InfoWindow 时能够使用 Angular2 模板语法.

据我所知，这意味着将组件作为模板字符串传递给 InfoWindow 构造函数对象中的 content 属性。

如果是这种情况，我认为我需要对组件模板进行字符串化。这是正确的(并且可能的)吗？

这是我认为我需要做的事情的一个例子:

// Component

import {Component} from 'angular2/core';
import {Thing} from './something/in/my/app/thing.model.ts';

@Component({
  selector: 'my-infowindow',
  template: `<p>This is an infowindow for {{ something.name }}</p>`
})
export class MyInfoWindowComponent {
    constructor(public something: Thing) {}
}


// Implementation

import {Thing} from './something/in/my/app/thing.model.ts';
import {MyInfoWindowComponent} from './path/to/infowindow.component';

/* { ...stuff... } */

private _buildInfoWindow(thing: Thing): google.maps.InfoWindow {
    return new google.maps.InfoWindow({
      /* v this is what I want v */
      content: new MyInfoWindowComponent(thing).toString() 
      /* ^ this is what I want ^ */
    });
}

尝试传递 ElementRef angular.io/docs/ts/latest/api/core/ElementRef-class.html。

或者使用 ViewChild 的东西:

我不会为你写代码，但我的想法是这样的:

@Component({
  selector: 'my-infowindow',
  template: `<p #kiddo>This is an infowindow for {{ something.name }}</p>`
})
export class MyInfoWindowComponent {
    @ViewChild('kiddo') viewChild;
    constructor(public something: Thing) {}
    ngOnInit(){
        yourFunction(this.viewChild); //or viewChild.innerHtml or w/e works
    }
}
