[英]sharing between modules with AngularJS?
假設我有一個我要注入myApp
配置的stuff
模塊:
angular.module('myApp', ['stuff']).
config([function() {
}]);
有兩個子模塊:
angular.module("stuff", ["stuff.thing1","stuff.thing2"]);
這是第一個:
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);
}
};
}];
});
第二個是相同的,例如:
angular.module('stuff.thing2', []).provider("$thing2", function(){
var globalOptions = {};
this.options = function(value){
globalOptions = value;
};
this.$get = ['$http',function ($http) {
function Thing2(opts) {
var self = this, options = this.options = angular.extend({}, globalOptions, opts);
}
Thing2.prototype.getOptions = function(){
console.log(this.options.apiKey);
};
return {
thing2: function(opts){
return new Thing2(opts);
}
};
}];
});
您將注意到,您可以作為提供程序訪問它們以配置選項:
angular.module('myApp', ['stuff']).
config(['$thing1Provider', '$thing2Provider', function($thing1Provider, $thing2Provider) {
$thing1Provider.options({apiKey:'01234569abcdef'});
$thing2Provider.options({apiKey:'01234569abcdef'});
}]);
如果我們在控制器中,您可以覆蓋每個范圍,如:
controller('AppController', ['$scope','$thing1', function($scope, $thing1) {
var thing1 = $thing1.thing1({apiKey:'3kcd894g6nslx83n11246'});
}]).
但是,如果他們總是共享相同的財產呢? 如何在提供商之間分享內容?
angular.module('myApp', ['stuff']).config(['$stuff' function($stuff) {
//No idea what I'm doing here, just trying to paint a picture.
$stuff.options({apiKey:'01234569abcdef'});
}]);
我可以為$thing1
和$thing2
注入$stuff
並配置共享屬性嗎?
如何訪問$thing1
和$thing2
作為單個模塊的擴展?
controller('AppController', ['$scope','$stuff', function($scope, $stuff) {
//Again - no idea what I'm doing here, just trying to paint a picture.
//$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?
$stuff.options({apiKey:'uih2iu582b3idt31d2'});
}]).
將模塊注入共享這些屬性的模塊。
使用provider類覆蓋屬性或從任何范圍實例化它們:
angular.module("stuff.things", []).provider("$things", function(){
var globalOptions = {};
this.options = function(value){
globalOptions = value;
};
this.$get = [, function () {
function Things(opts) {
var self = this, options = this.options = angular.extend({}, globalOptions, opts);
}
Things.prototype.returnOptions = function(){
return this.options;
};
return {
things: function(opts){
return new Things(opts);
}
};
}];
});
秘訣: $things.things().returnOptions()
angular.module('stuff.thing1', ['stuff.things']).provider("$thing1", function(){
var globalOptions = {};
this.options = function(value){
globalOptions = value;
};
this.$get = ['$things', function ($things) {
function Thing1(opts) {
var self = this, options = this.options = angular.extend({}, $things.things().returnOptions(), globalOptions, opts);
...
}
return {
thing1: function(opts){
return new Thing1(opts);
}
};
}];
});
