我正在尝试在Angular 2.0.0-beta.15中使用手风琴或面板,但是当我尝试使其工作时,我收到以下消息"属性'ngOnDestroy'在类型'NgbAccordionGroup'中丢失"
import {bootstrap} from '@angular/platform-browser-dynamic';
import {Component, OnDestroy} from '@angular/core';
@Component({
selector: 'ngb-accordion,[ngb-accordion]',
inputs: ['onlyOneOpen: closeOthers'],
template: `<ng-content></ng-content>`
})
export class NgbAccordion {
private onlyOneOpen: boolean;
private groups: Array<NgbAccordionGroup> = [];
addGroup(group: NgbAccordionGroup): void { this.groups.push(group); }
closeOthers(openGroup): void {
if (!this.onlyOneOpen) {
return;
}
this.groups.forEach((group: NgbAccordionGroup) => {
if (group !== openGroup) {
group.isOpen = false;
}
});
}
removeGroup(group: NgbAccordionGroup): void {
const index = this.groups.indexOf(group);
if (index !== -1) {
this.groups.splice(index, 1);
}
}
}
@Component({
selector: 'ngb-accordion-group,[ngb-accordion-group]',
inputs: ['heading', 'isOpen', 'isDisabled'],
template: `
<div class="card">
<div class="card-header">
<a href tabindex="0"><span [class.text-muted]="isDisabled" (click)="toggleOpen($event)">{{heading}}</span></a>
</div>
<div class="card-block" [hidden]="!isOpen">
<div class="card-text">
<ng-content></ng-content>
</div>
</div>
</div>
`
})
export class NgbAccordionGroup implements OnDestroy {
private isDisabled: boolean;
private _isOpen: boolean = false;
constructor(private accordion: NgbAccordion) { this.accordion.addGroup(this); }
toggleOpen(event) {
event.preventDefault();
if (!this.isDisabled) {
this.isOpen = !this.isOpen;
}
}
onDestroy(): void { this.accordion.removeGroup(this); }
public get isOpen(): boolean { return this._isOpen; }
public set isOpen(value: boolean) {
this._isOpen = value;
if (value) {
this.accordion.closeOthers(this);
}
}
}
@Component({
selector: 'my-app',
templateUrl: './src/app.html'
directives: [NgbAccordion, NgbAccordionGroup]
})
export class App {
firstDisabled:boolean = false;
isOpen:boolean = false;
}
bootstrap(App, []).catch(err => console.error(err));
或者看看这里 http://plnkr.co/edit/we3EsK?p=preview现在正在RC1中工作,但我必须回到Angular 2.0.0-beta.15
有什么想法吗?
onDestroy(): void { this.accordion.removeGroup(this); }
应该是
ngOnDestroy(): void { this.accordion.removeGroup(this); }
错误消息来自
... implements OnDestroy {
没有实际实现其成员。
