我試圖將輸入參數傳遞給一個組件,但我得到這個異常: browser_adapter.ts:78 EXCEPTION:Error:Uncaught(in promise):No Directive在PropDecoratorFactory在PropDecoratorFactory上找到的Angular2 RC1No指令註解@Input
發現註釋我試圖解決描述here,並沒有解決這個問題對我來說:
這裏是我的代碼:
import {Component, provide, Input} from '@angular/core';
import {bootstrap} from '@angular/platform-browser-dynamic';
import {Http, HTTP_PROVIDERS} from '@angular/http';
import {RouteConfig, ROUTER_DIRECTIVES, Router, ROUTER_PROVIDERS} from '@angular/router-deprecated'
@Component({
selector: 'sub',
template : `<p>input: {{someInput}}</p>`,
directives: [Input]
})
export class SubComponent {
@Input() someInput: Number;
}
@Component({
selector: 'home',
template : `<p>home</p><sub [someInput]="someInput"></sub>`,
directives: [SubComponent]
})
export class HomeComponent {
someInput: Number = 123;
}
@Component({
selector: 'my-app',
template: '<h1>here!</h1><router-outlet></router-outlet>',
directives: [ROUTER_DIRECTIVES],
providers: [ROUTER_PROVIDERS]
})
@RouteConfig([
{ path: '/home', name: "Home", component: HomeComponent, useAsDefault: true}
])
export class App {
}

哇!這解決了它,非常感謝你! – BSSchwarzkopf
沒問題,'directives'數組只是用於你想在html模板中使用的指令/組件。 –
