Reactive form in Angular Daterangepicker component
27 Apr 20243 minutes to read
DateRangePicker is a form component and validation is playing vital role in forms to get the valid data.
Here to showcase the DateRangePicker with form validations we have used the reactive form.
The reactive forms uses the reactive model-driven technique to handle form data between component and view, due to that we also call it as the model-driven forms.
It’s listen the form data changes between App component and view, also returns the valid states and values of form elements.
For more details about Reactive Forms refer: https://angular.io/guide/reactive-forms
.
For the reactive forms, import a ReactiveFormsModule
into app module as well as the FormGroup
,
FormControl
should be imported to app component.
The FormGroup
is used to declare formGroupName
for the form and the FormControl
is used to declare formControlName
for form controls. Declare the formControlName
to DateRangePicker component as usual.
Then, create a value object to the FormGroup
and each value will be the default value of the form control.
The following example demonstrates how to use the reactive forms.
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule, ReactiveFormsModule } from '@angular/forms'
import { DateRangePickerModule } from '@syncfusion/ej2-angular-calendars'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { Component, OnInit, Inject } from '@angular/core';
import { DateRangePickerComponent } from '@syncfusion/ej2-angular-calendars';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { ButtonComponent } from '@syncfusion/ej2-angular-buttons';
import { FormsModule } from '@angular/forms';
@Component({
imports: [
FormsModule, ReactiveFormsModule, DateRangePickerModule, ButtonModule
],
standalone: true,
selector: 'app-root',
templateUrl: './template.html'
})
export class AppComponent implements OnInit {
skillForm?: FormGroup | any;
build: FormBuilder;
constructor(@Inject(FormBuilder) private builder: FormBuilder) {
this.build = builder;
this.createForm();
}
ngOnInit(): void {
throw new Error('Method not implemented.');
}
createForm() {
this.skillForm = this.build.group({
daterangepicker: ['', Validators.required],
username: ['', Validators.required],
usermail: ['', Validators.email],
});
}
get username() {
return this.skillForm?.get('username');
}
get daterangepicker() {
return this.skillForm?.get('daterangepicker');
}
get usermail() {
return this.skillForm?.get('usermail');
}
onSubmit() {
alert("Form Submitted!");
}
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
