Is there a way to manipulate the parent HTML element based on the output value sent to my component?

Within my codebase, I am utilizing two components - HrComponent and appcomponent. How can I effectively manage the boolean value IsBoolean from my HrComponent?

HrComponent

 @Input()LoginName: string;
    IsBoolean: boolean = false;

 @Output()BooleanExp: EventEmitter<boolean> = new EventEmitter<boolean>();

    onSelectChange() {
        this.BooleanExp.emit(this.IsBoolean);
    }

appcomponent

 Name: string = "Hello"
 <div>

        <HrSelector [LoginName]="Name">
            <span>{{LoginName}}</span>
            <div *ngIf="IsBoolean">
                <p>This is Special Div</p>
            </div>
        </HrSelector>
    </div>

Answer №1

Make sure to follow these steps:

 <HrSelector [LoginName]="Name" (BooleanExp)="onChange($event)">
        <span>{{LoginName}}</span>
        <div *ngIf="IsBoolean">
            <p>This is Special Div</p>
        </div>
 </HrSelector>

In your TypeScript file, create the onChange method:

onChange(event) {
    this.IsBoolean = event;
}
