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

时间:2024-01-15 12:46:20

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);
}
}
