First, add FormsModule in app.module.ts:
import { FormsModule } from '@angular/forms'; . . . @NgModule({ declarations: [. . .], imports: [ . . . FormsModule, . . . ], providers: [. . . ] })
Then the HTML elements:
<form #studentForm="ngForm" (ngSubmit)="submitStudentForm()"> <div> <label for="firstName">Student Name:</label> <input type="text" id="firstName" [(ngModel)]="model.firstName" name="firstName" placeholder="First Name" /> <input type="text" id="lastName" [(ngModel)]="model.lastName" name="lastName" placeholder="Last Name" /> </div> <div> <label for="email">Email:</label> <input type="text" id="email" [(ngModel)]="model.email" name="email" /> </div> <button type="submit">Update</button> </form>Note that we need to add a template reference variable, '#theFormName' and set its value to ngForm, in our example is <form #studentForm="ngForm">. In the example we also use [(ngModel)] on input fields for two ways data binding. name attribute for each input is also required by ngForm, otherwise it won't work.
Finally on the .ts file:
export class StudentComponent { model: Student = { firstName: 'John', lastName: 'Doe', email: 'john.doe@example.com' }; submitStudentForm(): void { . . . } }
