来自父组件的子组件中的角度调用函数

Question

I am getting error while calling function in parent component from child component. I think I am doing some mistake in child component while calling func() from parent

   parent component
    func(){...........}

    parent.html
    <child   (func)="func()"></child>

    child.component.ts
    @Output func = new EventEmitter();

someOtherFunc(){
    this.func.emit();
}

Answer 1

Try this,

parent.component.html

<child   (func)="func($event)"></child>

child.component.ts

@Output() func: EventEmitter<any> = new EventEmitter();
someOtherFunc(){
    this.func.emit(null);
}
