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} from ‘angular2/core‘;
import {TodoService} from ‘./TodoService‘;
@Component({
selector: ‘todo-input‘,
template: `
<form (submit)="onSubmit()">
<input type="text" [(ngModel)]="todoModule">
</form>
`
})
export class TodoInput{
todoModule: string;
constructor(public todoService: TodoService){
}
onSubmit(){
this.todoService.todos.push(this.todoModule);
console.log(this.todoService.todos);
}
}
