how to pass variable via component after it's updated angular
// you can try like this, here you want to get the data from the parent component to child component, Here your parent component is ParentComponent and child component is app-child so here for getting the data from parent to child we can use ngOnChanges(changes: SimpleChanges)
// ParentComponent.html
<app-child
[data]="data"
(filterEmmiter)="filter($event)">
</app-child>
// child.component.ts
import {Component, OnChanges, SimpleChanges, Input} from '@angular/core';
class Child implements OnInit, OnChanges {
@Input() Data: any; // here is the data variable which we are getting from the parent
constructor() {}
ngOnchanges(changes: SimpleChanges) {
console.log(changes); // here you will get the data from parent once the input param is change
}
}
