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);
}
};
}];
});
