The child element is triggering an output event that is in turn activating a method within the parent

Question

The child element is triggering an output event that is in turn activating a method within the parent

I am currently utilizing @Output in the child component to invoke a specific method in the parent component. However, I am encountering an issue where clicking on

(click)="viewPromotionDetails('Learn more')"

in the child component is also triggering

(click)="description()"

If anyone could assist me with resolving this dilemma, that would be greatly appreciated.

I have included a link to the code on StackBlitz for reference.

Thank you in advance for your help.

child.component.html

<div>
    <div>Name </div>
    <div>Description </div>
    <div class="lear-more" (click)="viewPromotionDetails('Learn more')">Learn More</div>
</div>

Parent component HTML: app.component.html

    <div class="description" (click)="description()">
        <my-child (leanMore)="callLearnMore($event)"></my-child>
    </div>

angular typescript

Answer №1

If you encounter issues with the code, attempt using e.stopPropagation() within viewPromotionDetails('Learn more'). Sadly, your stackblitz demo is currently dysfunctional.

My approach would involve transforming the div.learn-more into a button element. By doing this, we can prevent the click events from being passed up to higher ancestors, like the root element.

Inspect your parent HTML:

<div class="info" (click)="displayInfo()">
    <my-child (showMore)="handleShowMore($event)"></my-child>
</div>

Whenever the my-child is clicked, it triggers a click event on the parent div as well because it is nested within it, making it intuitive.

Here's my suggestion:

In your child-component.ts file, introduce a new @Output property named description:

@Output() public showMore: EventEmitter<string> = new EventEmitter();
@Output() public description: EventEmitter<string> = new EventEmitter();

Next, in the parent component's template file, remove the

(click)="displayInfo()"

, and attach it to the my-child instead.

<div class="info">
    <my-child (showMore)="handleShowMore($event)" (description)="displayInfo()"></my-child>
</div>

Lastly, in your child-component.html, include a click listener for the

<div>Description </div>

element. Therefore, the template should appear as follows:

<div>
    <div>Name </div>
    <div (click)="description.emit()">Description </div>
    <div class="read-more" (click)="viewFullDetails('Read more')">Read More</div>
</div>

I trust this solution will assist you with resolving your issue.
