AngularJS动态范围注入或控制器 [英] AngularJS dynamically inject scope or controller

问题描述

是否有可能在运行过程中注入范围或控制器？
或任何其他建议动态中注入服务控制器？

Is it possible to inject scope or controller during running ? or any other advice to dynamically inject services into controller ?

Application.controller('IndexController', function($scope){

    // some actions

    if(someconditions) {
            $scope.$inject = [someServiceName];
            // and here i want to use service methods 
    }

});

在此先感谢

推荐答案

一个服务可以使用的 $注射器。如果能够通过控制器参数注入的服务就是这样角度提供了方便。引擎盖下，在$喷油器所使用的角度来检索对象实例。但是，我们可以使用$喷射器还自己

A service can be dynamically injected (by name) into a controller using the $injector. Being able to inject services via controller arguments is just a convenience that Angular provides. Under the hood, the $injector is used by Angular to retrieve object instances. But we can use the $injector ourselves also.

function MyCtrl($scope, $injector) {
  $scope.doSomething = function(someService) {
    var service = $injector.get(someService)  // someService contains the name of a service
    service.value += 10
}
