I have two components in Angular 8:
Child component
import { Component } from '@angular/core';
@Component({
selector: 'child-component',
template: `<h2>Child component</h2>`
})
export class ChildComponent {
callMethod() {
console.log('call method of child component');
}
}
Parent component
@Component({
selector: 'parent-component',
template: '<div> <child-component></child-component> <button (click)="submit()">Call</button> <div>',
styleUrls: ['./app.component.css']
})
export class AppComponent {
constructor() { }
submit() {
// Call method of child component HERE
}
}
Now I want to call callMethod() method of child component inside submit() method of the parent component.
Please support me if you know any solution.

You can use
@ViewChildin parent component like in example:import { Component, ViewChild } from '@angular/core'; import { ChildComponent } from './child.component'; @Component({ selector: 'parent-component', template: '<div> <child-component></child-component> <button (click)="submit()">Call</button> <div>', styleUrls: ['./app.component.css'] }) export class AppComponent { @ViewChild(ChildComponent, {static: true}) private myChild: ChildComponent; constructor() { } submit() { // Call method of child component HERE myChild.callMethod(); } }If your version angular in your project is less then 8 you have to change:
@ViewChild(ChildComponent, {static: true}) private myChild: ChildComponent;to
@ViewChild(ChildComponent) private myChild: ChildComponent; -

In a simple way, you can call directly the child component method from Html with an alias. You can see code below:
@Component({ selector: 'parent-component', template: '<div> <child-component #childcomponent></child-component> <button (click)="childcomponent.callMethod()">Call</button> <div>', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { } }This way working for me.
