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

Posted 2020-06-26 Answer1215

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);
    }
}
