javascript – 使用AngularJS共享模块？

假设我有一个我想要注入到myApp配置的东西模块：

angular.module('myApp',['stuff']).
  config([function() {

  }]);

有两个子模块：

angular.module("stuff",["stuff.thing1","stuff.thing2"]);

这是第一个：

angular.module('stuff.thing1',[]).provider("$thing1",function(){
    var globalOptions = {};
    this.options = function(value){
        globalOptions = value;
    };
    this.$get = ['$http',function ($http) {
        function Thing1(opts) { 
            var self = this,options = this.options = angular.extend({},globalOptions,opts);  
        }
        Thing1.prototype.getoptions = function(){
            console.log(this.options.apiKey);
        };
        return {
            thing1: function(opts){
                return new Thing1(opts);
            }
        };
    }];
});

第二个例子是相同的：

angular.module('stuff.thing2',[]).provider("$thing2",function ($http) {
        function Thing2(opts) { 
            var self = this,opts);  
        }
        Thing2.prototype.getoptions = function(){
            console.log(this.options.apiKey);
        };
        return {
            thing2: function(opts){
                return new Thing2(opts);
            }
        };
    }];
});

您会注意到,您可以访问它们作为提供程序来配置选项：

angular.module('myApp',['stuff']).
  config(['$thing1Provider','$thing2Provider',function($thing1Provider,$thing2Provider) {
    $thing1Provider.options({apiKey:'01234569abcdef'});
    $thing2Provider.options({apiKey:'01234569abcdef'});
  }]);

如果我们在控制器中,您可以覆盖每个范围,如：

controller('AppController',['$scope','$thing1',function($scope,$thing1) {    
  var thing1 = $thing1.thing1({apiKey:'3kcd894g6nslx83n11246'});  
}]).

但是如果他们总是分享相同的财产呢？如何在供应商之间分享内容？

angular.module('myApp',['stuff']).config(['$stuff' function($stuff) {
  //No idea what I'm doing here,just trying to paint a picture.
  $stuff.options({apiKey:'01234569abcdef'});
}]);

可以为$thing1和$thing2注入$东西并配置共享属性吗？

如何访问$thing1和$thing2作为单个模块的扩展？

controller('AppController','$stuff',$stuff) {
  //Again - no idea what I'm doing here,just trying to paint a picture.

  //$thing1 would Now be overwrite $stuff.options config above.
  var thing1 = $stuff.$thing1.thing1({apiKey:'lkjn1324123l4kjn1dddd'});

  //No need to overwrite $stuff.options,will use whatever was configured above.
  var thing2 = $stuff.$thing2.thing2();  

  //Could I even change the default again for both if I wanted too?
  $stuff.options({apiKey:'uih2iu582b3idt31d2'});
}]).

解决方法

将模块注入两个共享这些属性的模块.

使用provider类覆盖属性或将其从任何范围中实例化：

angular.module("stuff.things",[]).provider("$things",function(){
    var globalOptions = {};
    this.options = function(value){
        globalOptions = value;
    };
    this.$get = [,function () {
        function Things(opts) { 
            var self = this,opts);
        }
        Things.prototype.returnoptions = function(){
            return this.options;
        };
        return {
            things: function(opts){
                return new Things(opts);
            }
        };
    }];
});

秘密酱：$things.things().returnoptions()

angular.module('stuff.thing1',['stuff.things']).provider("$thing1",function(){
    var globalOptions = {};
    this.options = function(value){
        globalOptions = value;
    };

    this.$get = ['$things',function ($things) {
        function Thing1(opts) {
            var self = this,$things.things().returnoptions(),opts);
        ...
        }
        return {
            thing1: function(opts){
                return new Thing1(opts);
            }
        };
    }];
});
