How to add animations to individual items in an Angular list on click

Struggling to animate a single list item upon clicking, I realized the animation trigger is not being accessed in the onclick event code.

A helpful solution I found while searching can be viewed here.

<button mat-flat-button (click)="finishedChore('morning')">
<img [@openClose]="ismorning" src="assets/images/morning.png" />
</button>
<button mat-flat-button (click)="finishedChore('poop')">
<img [@openClose]="ispoop" src="assets/images/poop.png" />
</button>
<button mat-flat-button (click)="finishedChore('cleanRoom')">
<img [@openClose]="iscleanRoom" src="assets/images/cleanRoom.png" />
</button>
<button mat-flat-button (click)="finishedChore('cleanSinks')">
<img [@openClose]="iscleanSinks" src="assets/images/cleanSinks.png" />
</button>
<button mat-flat-button (click)="finishedChore('evening')">
<img [@openClose]="isevening" src="assets/images/evening.png" />
</button>

Creating Boolean variables for each item may become overwhelming with a large number of items or unpredictable quantity.

Is there an alternative method available, or is it possible to access the animation trigger in the code for better control?

Answer №1

To ensure the event is properly handled in your onClick function, pass it as a parameter and specify the id as an example:

<button mat-flat-button (click)="handleEvent($event)" id="exampleId">

This way, you can easily access all necessary information within your .ts file.

handleEvent(event) {
   var element = event.target || event.srcElement || event.currentTarget;
   var idValue = element.attributes.id.value;
}
