BSModelservice回调函数返回错误。 我正在使用angular 6和ngx-bootstrap / modal

Question

I am getting below exception.

ERROR TypeError: this.callBackOnSave.emit is not a function

Child Component

@Input() showDeleteBtn: boolean = true;
@Input() showGrid: boolean = true;
@Output() callBackOnSave: EventEmitter<null> = new EventEmitter();

this.callBackOnSave.emit();

Parent component

callBackOnSave(){
  console.log("got it***");
}

const initialState = {
  showDeleteBtn: false,
  showGrid: false,
  callBackOnSave: 'callBackOnSave()'
};

this.modalService.show(ScheduleComponent, {class: 'modal-md',  initialState});

Can anyone faced this issue. Please advice.

Answer 1

It seems you are keeping this statement this.callBackOnSave.emit(); outside of function. I don't think you will be doing this blunder but wondering by looking at your question. If yes then move inside the method if not then share the more code.

Answer 2

How does your Parent component's template look? it should have something like

<app-child-component (callBackOnSave)="callBackOnSave($event)">...</app-child-componen>
