Angular2:通过指令将外部Component注入其他组件无效

Question

我希望子组件模板加载到父组件模板中.(由于缺乏更好的措辞,我称之为孩子和父母)

这是我的孩子:

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() {

    }
}

这是我的父母:

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

和父母的HTML:

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

有什么想法错了吗？

从Angular 2 Cheat Sheet(搜索选择器)中可以看出,通过使用括号,您可以限制调用指令的位置.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[]所有应该是好的
