有必要将$ scope注入到angularjs中的控制器吗? [英] Is it necessary to inject $scope to a controller in angularjs?

问题描述

以下两个代码段之间是否有区别?两者都可以.

Is there any difference between the following two code snippet? Both work.

1.

myApp.controller("myAppController", ["$scope", function($scope) {
// function body
}]);

2.

myApp.controller("myAppController", function($scope) {
// function body
});

推荐答案

嗯，在最小化过程中会产生差异.如果您不按照步骤1进行操作，则缩小会破坏您的代码.

Well, difference will create during minfication. If you don't follow the step1 , minification will break your code.

将您的第一个代码的版本版本化

Uglify Version of your 1st code

myApp.controller("myAppController",["$scope",function(o){}])

第二个代码的丑化版本

myApp.controller("myAppController",function(o){})

如果遵循步骤1，Angular将从注入中找到o的定义.

If you follow step 1 , Angular will find definition of o from injection.

但是，如果您按照步骤2进行操作，Angular将无法从任何来源找到o的定义.

But if you follow step 2 , Angular won't find definition of o from any source.
