This blog represents concepts and code samples which can be used for capturing user inputs from the form in an Angular app using following techniques:
The following depicts the code which needs to be used in template code. Make a note of
<input (keyup)="setFirstname($event)"/>
The following depicts the code which needs to be used in the component code.
setFirstname(event: any) { this.uName = event.target.value; }
The following depicts the code which needs to be used in template code. Make a note of usage of # (hash) with the template reference variable, email. The reference variable, #email, represents the input element.
<input #email (keyup)="setEmail(email.value)"/>
The following depicts the code which needs to be used in the component code.
setEmail(value: string) { this.uEmail = value; }
The following code represents the template file, app.component.html.
<div> <form> <div class="form-group"> <label for="emailField">Email address</label> <input type="email" class="form-control" id="emailField" #email (keyup)="setEmail(email.value)" placeholder="name@example.com"/> </div> <div class="form-group"> <label for="fullname">Name</label> <input class="form-control" id="fullname" (keyup)="setFirstname($event)" placeholder="Full Name"/> </div> </form> </div> <hr/> <ul> <li>Email: {{uEmail}}</li> <li>First name: {{uName}}</li> </ul>
The following code represents the component, namely, app.component.ts.
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { public title = 'Angular Forms Tutorial'; uEmail = ''; uName = ''; setEmail(value: string) { this.uEmail = value; } setFirstname(event: any) { this.uName = event.target.value; } }
