Angular2:通过指令将外部组件注入其他组件无效

Angular2: Inject external Component into other component via directive not working

我希望 child 组件模板加载到 parent 组件模板中。 (由于缺乏更好的措辞,我称它们为 child 和 parent)

这是我的 child:

import {Component,Directive, ElementRef, Input} from '@angular/core';
import {IONIC_DIRECTIVES} from 'ionic-angular';


@Component({ 
  selector: '[parentselector]',
  template: '<div>I AM A CHILD</div>',
  directives: [IONIC_DIRECTIVES] 
})


export class ChildPage {
    constructor() {

    }
}

这是我的 parent:

@Component({
    templateUrl: 'build/pages/parent/parent.html',
    directives: [ChildPage]
})

和Parent的HTML:

<ion-content>
    <ion-slides>
        <ion-slide><parentselector>Parent To Be Overriden</parentselector>
        </ion-slide>
    </ion-slides>
</ion-content>

知道哪里出了问题吗?

Angular 2 Cheat Sheet(搜索选择器)中,它表示通过使用括号可以限制可以调用指令的位置。例如:

selector:'[parentselector]' - means you can only select as an attribute
selector:'parentselector' - means you can only select as an element
selector:'.parentselector' - means you can only select as a css class

所以如果你脱掉 [] 一切都应该很好
