问题描述

是否可以在运行期间注入作用域或控制器?或任何其他建议将服务动态注入控制器?

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 
    }

});

推荐答案

可以使用 $injector.能够通过控制器参数注入服务只是 Angular 提供的一种便利.在幕后，Angular 使用 $injector 来检索对象实例.但是我们也可以自己使用 $injector.

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
}
