[英]is there a way i can fix my accordion in angular?
我是 angular 的新手,我試圖制作一個手風琴組件,但它沒有像我想要的那樣工作,這是我的 html 代碼。
<div class="faq-item-container">
<h1 class="mt-1 mb-5"><strong>Frequently Aksed Questions</strong></h1>
<div class="row" (click)="toggleDetail(); toggleIcon();" *ngFor= "let faq of faqs">
<div class="col my-2">
<h3> {{faq.title}} <a><fa-icon [icon]="faChevronDown" class="float-right"></fa-icon></a></h3>
</div>
<div class="col-12" *ngIf="showDetail">
<div class="faq-detail-container mt-1">
<div class="col-12">
<p><small>
{{faq.content}}
</small></p>
</div>
</div>
</div>
</div>
</div>
這是 ts 代碼
import { Component, OnInit } from '@angular/core';
import {faChevronUp, faChevronDown, IconDefinition, faSquare} from '@fortawesome/free-solid-svg-icons';
@Component({
selector: 'app-jobs-faq',
templateUrl: './jobs-faq.component.html',
styleUrls: ['./jobs-faq.component.scss']
})
export class JobsFaqComponent implements OnInit {
faChevronUp: IconDefinition = faChevronUp;
faChevronDown: IconDefinition = faChevronDown;
showDetail: boolean;
faqs = [
{
id: 1,
title: 'faq1',
content: 'content1'
},
{
id: 2,
title: 'faq2',
content: 'content2'
},
{
id: 3,
title: 'faq3',
content: 'content3'
}
];
constructor() {
this.showDetail = false;
}
toggleDetail(): void {
this.showDetail = !this.showDetail;
}
toggleIcon() {
if (this.faChevronDown === faChevronDown) {
this.faChevronDown = faChevronUp;
} else {
this.faChevronDown = faChevronDown;
}
}
ngOnInit() {
}
}
問題是當我點擊 faq1 時,其他人也崩潰了,是的,我知道這是因為我調用了相同的函數,這就是我想問的,如何單獨調用該函數以使這個手風琴像它應該的那樣工作? 謝謝。
這取決於您是否想在單擊一個部分時關閉所有其他部分,但解決方案可能看起來像這樣:
<div class="faq-item-container">
<h1 class="mt-1 mb-5"><strong>Frequently Aksed Questions</strong></h1>
<div class="row" (click)="toggleDetail(faq.id); toggleIcon();" *ngFor= "let faq of faqs">
<div class="col my-2">
<h3> {{faq.title}} <a><fa-icon [icon]="faChevronDown" class="float-right"></fa-icon></a></h3>
</div>
<div class="col-12" *ngIf="faq.showDetail">
<div class="faq-detail-container mt-1">
<div class="col-12">
<p><small>
{{faq.content}}
</small></p>
</div>
</div>
</div>
</div>
</div>
import { Component, OnInit } from '@angular/core';
import {faChevronUp, faChevronDown, IconDefinition, faSquare} from '@fortawesome/free-solid-svg-icons';
@Component({
selector: 'app-jobs-faq',
templateUrl: './jobs-faq.component.html',
styleUrls: ['./jobs-faq.component.scss']
})
export class JobsFaqComponent implements OnInit {
faChevronUp: IconDefinition = faChevronUp;
faChevronDown: IconDefinition = faChevronDown;
faqs = [
{
id: 1,
title: 'faq1',
content: 'content1',
showDetail: false
},
{
id: 2,
title: 'faq2',
content: 'content2',
showDetail: false
},
{
id: 3,
title: 'faq3',
content: 'content3',
showDetail: false
}
];
toggleDetail(faqId: number): void {
this.faqs = this.faqs.map(faq => {
faq.showDetail = (faq.id == faqId) ? !faq.showDetail : false;
return faq;
});
}
toggleIcon() {
if (this.faChevronDown === faChevronDown) {
this.faChevronDown = faChevronUp;
} else {
this.faChevronDown = faChevronDown;
}
}
ngOnInit() {
}
}
請注意,您的 [icon]="faChevronDown" 應該基於您的 *ngFor 范圍內的常見問題解答。 我會把它留給你作為練習來找到解決方案。 (提示:你可以使用基於 faq.showDetail 的三元運算)
