If I have the template below, how can I use TypeScript to bind a click event by class? My goal is to retrieve attributes of the clicked element.
<ul>
<li id="1" class="selectModal">First</li>
<li id="2" class="selectModal">Second</li>
<li id="3" class="selectModal">Third</li>
</ul>
Exploring various methods to achieve this goal. A simple solution can be implemented as follows:
<ul (click)="handleClick($event.target)">
<li id="1" class="toggleModal">Primary</li>
<li id="2" class="toggleModal">Secondary</li>
<li id="3" class="toggleModal">Tertiary</li>
</ul>
handleClick(eventTarget: HTMLElement) {
console.log(eventTarget.id, eventTarget.className);
}
Absolutely, the approach you take depends on your strategy. One way to achieve this is through jQuery or by utilizing DOM accessors. In my experience working with a team, we prefer using JQuery, but we avoid searching the entire DOM to locate elements. Instead, we utilize a class known as ElementRef:
import { ElementRef } from '@angular/core';
...
constructor(private elementRef : ElementRef) {
}
ngAfterViewInit() {
jQuery(this.elementRef.nativeElement).find('selectModal').on('click', () => {
//perform actions here
});
}
The ElementRef class serves as a reference to the component within the DOM, allowing us to narrow down our search specifically to this component.
