问题描述

我正在尝试构建ionic2应用程序.我想在检测到ibeacon时向用户发送通知.它在angularjs中使用了此代码.像下面的代码一样，如何使用angular2做到这一点?

I'm trying to build an ionic2 application. I want to send notifications to users when ibeacon is detected. It worked with this code in angularjs. How can I do this with angular2 like the code below?

<div class="row"  ng-controller="Example1Controller" ng-init="add()">

推荐答案

<div class="row"  ng-controller="Example1Controller" ng-init="add()">

基本上在上面的代码ng-controller中定义了控制器部分，它是angular2的.ts文件(构造函数)，您可以从那里调用任何方法或任何方法，而且angular2中还存在ngOnInit()生命周期挂钩.

Basically in above code ng-controller define the controller part which is .ts file (constructor) for angular2 you can call any method or anything from there, also there is ngOnInit() life cycle hook present in angular2.
