I have a simple reactive form and I took the guide from https://medium.com/@jinalshah999/reactive-forms-in-angular-a46af57c5f36 to make the reactive form for validation in angular 9.
I dont know I posted in stackbliz but I got three links:
EDITOR URL
https://stackblitz.com/edit/angular
APP URL
https://angular.stackblitz.io
EMBED URL
https://stackblitz.com/edit/angular?embed=1&file=src/app/app.component.html
If,it is not working please say me where can I get real link.
app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';
@NgModule({
imports: [ BrowserModule, FormsModule , ReactiveFormsModule],
declarations: [ AppComponent, HelloComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
app.component.ts
import { Component } from '@angular/core';
import { FormGroup, FormBuilder,Validators } from '@angular/forms';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
checkoutFormGroup: FormGroup;
name = 'Angular';
constructor(private formBuilder: FormBuilder) { }
ngOnInit() {
this.checkoutFormGroup = this.formBuilder.group({
customer: this.formBuilder.group({
firstName: ['',Validators.required],
