关于 angularjs:Angular 模块仅适用于内联 javascript

Angular module only works with inline javascript

我正在学习 Angular,并且仅当所有代码都内联在页面上时,才能将控制器添加到我的模块中。如果我用 <script src="myModuleFile.js"> 替换它,它会失败

"Error: [$injector:unpr]
http://errors.angularjs.org/1.3.11/$injector/unpr?p0=aProvider%20%3C-%20a%20%3C-%20personController

var app = angular.module('app', [])
.config([function(injectables){

}]).run([function(injectables){

}]).controller("personController", function($scope){
    $scope.firstName ="John";
    $scope.lastName ="Doe";
});

正如 Claies 在评论中提到的,错误消息看起来像是在尝试为依赖项"a"寻找提供者,这可能是缩小的结果。

如果你喜欢:

1
angular.module(..).controller("SomeCtrl", function($scope){});

它可能会将$scope 缩小为a。因此,您应该使用:

1
angular.module(..).controller("SomeCtrl", ["$scope", function($scope){}]);

因为字符串不会被缩小,Angular 会知道哪个依赖是哪个。当然,另一种方法是使用 $injector,正如 Claies 也提到的那样。
