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); } }; }]; });
