// 写法一:
1 @Components({
2 ....,
3 inputs:['init'],
4 outputs:['finish']
5 })
6 export class xxx(){ 7 okEvent: EventEmitter<any> = new EventEmitter(); 8 9 ok(){ 10 // this should match the type define in EventEmitter 11 this.okEvent.emit('the value want to pass'); 12 } 13 } 14 15 // in another components 16 <ddd (finish)="finish($event)" [init]="value pass in"></ddd> 17 18 $event => will catch the return value
1 // 另外一种写法:
2 import { Component, View, Input, Output, EventEmitter } from 'angular2/angular2';
3
4 @Components({
5 ....
6 })
7 export class xxx(){
8 @Input() init; 9 // @Output(alias name) 10 @Output('finish') okEvent:EventEmitter<Any> = new EventEmitter(); 11 12 13 ok(){ 14 // this should match the type define in EventEmitter if use typescript 15 this.okEvent.emit('the value want to pass'); 16 } 17 } 18 19 // in another components 20 <ddd (finish)="finish($event)" [init]="value pass in"></ddd> 21 22 $event => will catch the return value
