为什么不AppCtrl已经$注资，但MyCtrl1确实在这个AngularJS例子吗？ [英] Why doesn't AppCtrl have $inject but MyCtrl1 does in this AngularJS example?

问题描述

我在看这个angularjs / socket.io例子，但我想知道为什么AppCtrl没有$注射线和MyCtrl1呢？

I am looking at this angularjs/socket.io example, but I was wondering why AppCtrl doesn't have a $inject line and MyCtrl1 does?

controllers.js：

controllers.js:

'use strict';

/* Controllers */

function AppCtrl($scope, socket) {
  socket.on('send:name', function (data) {
    $scope.name = data.name;
  });
}

function MyCtrl1($scope, socket) {
  socket.on('send:time', function (data) {
    $scope.time = data.time;
  });
}
MyCtrl1.$inject = ['$scope', 'socket'];


function MyCtrl2() {
}
MyCtrl2.$inject = [];

推荐答案

由于AppCtrl使用依赖注入，它也应该使用$喷出，以防止微小模糊处理。布赖恩只是忘记添加该行。

Since AppCtrl is using dependency injection, it should also be using $inject to protect against minification obfuscation. Brian just probably forgot to add that line.
