javascript - 无法将数据从 Controller 绑定(bind)到 View 。控制台没有错误

Question

您好，我正在学习 Angular 并尝试将数据从模型绑定(bind)到 View 。但它没有抛出任何错误。你能帮帮我吗。

<div ng-app ="myApp" ng-controller="emp"> 
 Hello {{emp.name}}, I am happy that you are getting a salary of{{emp.salary}}.
</div> 

---

var app = angular.module("myApp", []);

app.controller('emp', function(){
 this.name = "John";
 this.salary = 4500;
});

请查找Fiddler

将 ng-controller="emp" 更改为 ng-controller="emp as emp"

<div ng-app ="myApp" ng-controller="emp as emp"> 
     Hello {{emp.name}}, I am happy that you are getting a salary of{{emp.salary}}.
    </div>
