This is just simple usecase, but don't get what I'm missing.
I've componentA & componentB. Passing booloan value via click event from componentB to componentA using eventEmitter , to show/hide particular div in componentA.
So far
public showLayOut = false;
@Output() passThisValue = new EventEmitter<boolean>();
ngOnInit(): void {
this.showLayOut = false;
}
triggerEventToPassBoolVal() {
this.someService(baseLink).subscribe((data) => {
if (data[0].status === true) {
this.showLayOut = true;
if (this.showLayOut) {
this.passThisValue.emit(this.showLayOut);
}
}
})
}
<div *ngIf="showLayOut">
<p>Show this div if emitted value is true, otherwise hide</p>
</div>
Could anyone pls help me to point out what i did wrong?, if possible pls share any existing stackblitz working sample
Note: im using form like this to submit data (ngSubmit)="OK(data)"
Thanks
If componentA is parent component of componentB . I have that solution. for ex:
import { Component, OnInit, ViewContainerRef } from '@angular/core';
// componentB.compoent.ts
getParentComponent() {
return this.viewContainerRef['_data'].componentView.component.viewContainerRef['_view'].component;
}
changeBooleanvalueMethod () {
this.getParentComponent().showLayOut = true; // showLayOut is componentA variable
}
