用于自定义可重用组件的Angular2数据绑定

我想要一个包含标签和文本框的模板.此模板可以在我的页面的不同位置重复使用.做到这一点,我创建了一个MyTextComponent.我想知道如何将不同的值绑定到组件输入.

例如：

MyTextComponent

import {Component,Input} from 'angular2/core';
@Component({
    selector: 'myText',template:`<label>{{someLabel}}</label>
                 <input id=myId type="text" [(ngModel)]=bindModelData>
                 `
})
export class MyTextComponent {
    @input() myId : string;
    @input() bindModelData: any;
}

MyPageComponent

import {Component} from 'angular2/core';
import {MyTextComponent} from './MyTextComponent.component'

@Component({
    template:`<myText myId="id1" bindModelData="myString1"></myText>
              <myText myId="id2" bindModelData="myString2"></myText>
              `,directives:[MyTextComponent]
})
export class MyPageComponent{
    myString1: string;
    myString2: string;
}

我如何将MyTextComponent输入的ngModel绑定到MyPageComponent局部变量？

编辑：
添加@Output后试过,但没有工作:(
MyPageComponent中的插值是空白的,日志正在打印未定义.然而,插值是为mytextComponent工作.有任何想法吗

import {Component} from 'angular2/core';
import {MyTextComponent} from './myText.component'

@Component({
    template:`<myText myId="id1" [(bindModelData)]="myString1"></myText>
              <myText myId="id2" [(bindModelData)]="myString2"></myText>
              {{myString1}}
              {{myString2}}

              <button (click)="clicked()">Click Me</button>
              `,directives:[MyTextComponent],selector:'myPage'
})
export class MyPageComponent{
    myString1: string;
    myString2: string;

    clicked(){
        console.log(this.myString1+'--'+this.myString2);
    }
}


import {Component,Input,Output,EventEmitter} from 'angular2/core';
@Component({
    selector: 'myText',template:`<label>{{someLabel}}</label>
                 <input id=myId type="text" [ngModel]=bindModelData (ngModelChange)="updateData($event)">
                 modeldata - {{bindModelData}}
                 `
})
export class MyTextComponent {
    @input() myId : string;
    @input() bindModelData: any;
    @Output() bindModelDataChanged: any = new EventEmitter();
    updateData(event) {
       console.log('some random text');
      this.bindModelData = event;
      this.bindModelDataChanged.emit(event);
    }
}

你的myText缺少一个@Output()

import {Component,Output} from 'angular2/core';
@Component({
    selector: 'myText',template:`<label>{{someLabel}}</label>
                 <input id=myId type="text" [ngModel]=bindModelData (ngModelChange)="updateData($event)">
                 `
})
export class MyTextComponent {
    @input() myId : string;
    @input() bindModelData: any;

    // note that this must be named as the input name + "Change"
    @Output() bindModelDataChange: any = new EventEmitter();              

    updateData(event) {
      this.bindModelData = event;
      this.bindModelDataChange.emit(event);
    }
}

那么你可以使用它

import {Component} from 'angular2/core';
import {MyTextComponent} from './MyTextComponent.component'

@Component({
    template:`<myText myId="id1" [(bindModelData)]="myString1"></myText>
              <myText myId="id2" [(bindModelData)]="myString2"></myText>
              `,directives:[MyTextComponent]
})
export class MyPageComponent{
    myString1: string;
    myString2: string;
}
