Angularjs依赖注入的决心

Angularjs依赖注入的决心

本文介绍了Angularjs依赖注入的决心的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想用在 MyCtrl1 适当的依赖注入注入 MyCtrl1.resolve 对象的字段。我试过试图注入 @ MyCtrl1.resolve 等,没有运气的许多不同的组合。

  @ MyCtrl1 =($范围,$ HTTP,蝙蝠侠,标题) -  GT;
  $ scope.batman = batman.data
  $ scope.title = title.data@ MyCtrl1.resolve = {
 蝙蝠侠:($ HTTP) - GT;
   $ http.get('batman.json')
 标题:($ HTTP) - GT;
   $ http.get('title.json')
}
#@MyCtrl1.$inject ='$范围,$ HTTP'] - 因为不知道如何注入决心领域注释掉 角
.module('应用',[])
的.config(['$ routeProvider','$ locationProvider',($ routeProvider,$ locationProvider) - GT;
  $ locationProvider.html5Mode(真)  $ routeProvider.when('/',{templateUrl:'的index.html',控制器:MyCtrl1,解析:MyCtrl1.resolve})
  $ routeProvider.otherwise({redirectTo:'/'})
])angular.bootstrap(文件,['应用'])


解决方案

解决是一个路由的属性,而不是一个控制器。控制器将与上一个路线级别上定义的依赖被注入,没有必要在控制器上指定解析属性

考虑您的例子之一(转换为JavaScript),你可以定义你的控制器一如既往,那就是:

  MyCtrl1 =功能($范围,$ HTTP,蝙蝠侠,标题){
  $ scope.batman = batman.data;
  $ scope.title = title.data;
}

,然后路线上的resolve属性:

  angular.module(应用,[])。配置(['$ routeProvider','$ locationProvider',函数($ routeProvider,$ locationProvider){
  $ locationProvider.html5Mode(真)  $ routeProvider.when('/',{templateUrl:'的index.html',控制器:MyCtrl1,解析:{
    蝙蝠侠:['$ HTTP',函数($ HTTP){
      返回$ http.get(..)。然后(功能(响应){
         返回response.data;
      });
    }],
    标题:['$ HTTP',函数($ HTTP){
      如上返回//
    }]
  }});
  $ routeProvider.otherwise({redirectTo:'/'});
}]);

如果你想使用的路由,你需要使用数组风格的标注的决心部分再缩小code - 我在上面的例子中包括在本

I would like to use proper dependency injection in MyCtrl1to inject the fields of the MyCtrl1.resolve object. I've tried many different combinations of attempting to inject @MyCtrl1.resolve etc. with no luck.

@MyCtrl1 = ($scope, $http, batman, title) ->
  $scope.batman = batman.data
  $scope.title = title.data

@MyCtrl1.resolve = {
 batman: ($http) ->
   $http.get('batman.json')
 title: ($http) ->
   $http.get('title.json')
}
#@MyCtrl1.$inject = ['$scope', '$http'] -- commented out because not sure how to inject resolve fields

 angular
.module( 'app', [])
.config( ['$routeProvider', '$locationProvider', ($routeProvider, $locationProvider)->
  $locationProvider.html5Mode(true)

  $routeProvider.when('/', {templateUrl: 'index.html', controller: MyCtrl1, resolve: MyCtrl1.resolve})
  $routeProvider.otherwise({redirectTo: '/'})
])

angular.bootstrap(document,['app'])
解决方案

Resolve is a property of a route and not a controller. Controllers would be injected with dependencies defined on a route level, there is no need to specify resolve properties on a controller.

Taking one of your examples (transformed to JavaScript), you would define your controller as always, that is:

MyCtrl1 = function($scope, $http, batman, title) {
  $scope.batman = batman.data;
  $scope.title = title.data;
}

and then the resolve property on a route:

angular.module('app', []).config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
  $locationProvider.html5Mode(true)

  $routeProvider.when('/',{templateUrl: 'index.html', controller: MyCtrl1, resolve: {
    batman: ['$http', function($http) {
      return $http.get(..).then(function(response){
         return response.data;
      });
    }],
    title: ['$http', function($http) {
      return //as above
    }]
  }});
  $routeProvider.otherwise({redirectTo: '/'});
}]);

If you want to minify the code using resolve section of routing you need to use array-style annotations - I've included this in the example above.
