[Angular 2] Using ng-model for two-way binding

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: `
        <form action="" (ng-submit)="onSubmit()">
            <input type="text" [(ng-model)]="todoModule">{{todoModule}}
        </form>
    `
})
export class TodoInput{
    todoModule;

    constructor(
        //@Inject(TodoService) todoService
        public todoService:TodoService
    ){
        this.todoService = todoService;
        console.log(todoService);
    }

    onSubmit(){
        this.todoService.addTodo(this.todoModule);
    }
}
