The form can be build with Angular template syntax easily along with form specific directives.
This template-driven forms uses the ng
directives in view to handle the forms controls.
For more details about template-driven Forms refer to:https://angular.io/guide/forms#template-driven-forms.
name
attribute to TimePicker element which will be used to identify the
form element. To register an TimePicker element to ngForm, give the ngModel to it
so the FormsModule will automatically detect the TimePicker as a form element.
After that, the TimePicker value will be selected based on the ngModel value.The following example demonstrates template driven forms with TimePicker component.
import { Component,ViewChild, ViewEncapsulation, Inject } from '@angular/core';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';
import { TimePickerComponent } from '@syncfusion/ej2-angular-calendars';
class User {
constructor() {
public time: Date
}
}
@Component({
selector: 'app-root',
templateUrl: './app/template.html'
})
export class DefaultTimePickerComponent {
user: User;
ngOnInit() {
this.user = new User(null);
}
onSubmit(userForm) {
(userForm.valid) ? alert("submitted"): alert("form is invalid");
}
}
import { DefaultTimePickerComponent } from './app.component';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { TimePickerModule } from '@syncfusion/ej2-angular-calendars';
@NgModule({
imports: [ FormsModule, ReactiveFormsModule, BrowserModule, TimePickerModule],
declarations: [DefaultTimePickerComponent],

})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
