Two-way binding still exists in Angular 2 and ng-model makes it simple. The syntax is a combination of the [input] and (output) syntax to represent that the data is being pushed out and pulled in.
import {Component, View, FORM_DIRECTIVES} from "angular2/angular2";import {TodoService} from "./todoService";@Component({ selector: 'todo-input'})@View({ directives: [FORM_DIRECTIVES], template: ``})export class TodoInput{ todoModule; constructor( //@Inject(TodoService) todoService public todoService:TodoService ){ this.todoService = todoService; console.log(todoService); } onSubmit(){ this.todoService.addTodo(this.todoModule); }}
