【问题描述】:
我正在尝试使用 TypeScript 构建 Ionic2 和 AngularJS2 应用程序,但出现错误:异常:没有 CalEvent 提供程序!
// File event.ts
export class CalEvent {
name: string;
date: Date;
description: string;
isComplete: boolean;
constructor(n: string, d: Date){
this.name = n;
this.date= d;
}
toString(){
return this.name + ' at ' + this.date;
}
}
/*****************************/
// File event_card_large.ts
import {Component} from 'angular2/core'
import {CalEvent} from '../classes/event.ts';
@Component({
selector: 'event-card-large',
template: '<div style="color: red;">here</div>'
})
export class EventCardLarge{
constructor(public calEvent: CalEvent){}
}
/*****************************/
// File my_page.ts
import {Page} from 'ionic-angular';
import {CalEvent} from '../../classes/event.ts';
import {EventCardLarge} from '../../components/event_card_large.ts';
@Page({
templateUrl: 'build/pages/my_page/my_page.html',
directives:[EventCardLarge]
})
export class MyPage {
public pageName: string;
public testItems: CalEvent[];
selectedItem = 0;
constructor() {
// Test code
this.pageName = 'Test Page 2016-05-17';
this.testItems = [];
let d1 = new Date('2016-05-17');
let ce = new CalEvent('The name', d1);
ce.isComplete = true;
this.testItems.push();
}
}
/*****************************/
// File my_page.html
...
<ion-item *ngFor="#v of testItems; #i = index" >
<event-card-large [calEvent]="v">Loading...</event-card-large>
</ion-item>
...
感谢您的帮助。
