1、factory
用Factory 就是创建一个对象,为它添加属性,然后把这个对象返回出来。你把 service 传进 controller 之后,在 controller 里这个对象里的属性就可以通过 factory 使用了。
- <!doctypehtml>
- <htmllang="en">
- <head>
- <Metacharset="UTF-8">
- <title>Document</title>
- <scriptsrc="angular.min.js"></script>
- <script>
- angular.module('mod',[])
- //定义工厂模块-factory
- .factory('fact',[function(){
- return{
- str:"testfactory",sum:function(n1,n2){
- returnn1+n2
- }
- };
- }])
- //添加依赖注入模块fact
- .controller('testCtrl',['$scope','fact',function($scope,fact){
- alert(fact.str)
- }])
- </script>
- </head>
- <bodyng-app='mod'ng-controller='testCtrl'>
- </body>
- </html>
2、provide
Providers是唯一一种你可以传进 .config() 函数的 service。当你想要在 service 对象启用之前,先进行模块范围的配置,那就应该用 provider。
- <!doctypehtml>
- <htmllang="en">
- <head>
- <Metacharset="UTF-8">
- <title>Document</title>
- <scriptsrc="angular.min.js"></script>
- <script>
- angular.module('mod',[])
- .controller('modCtrl','prod',prod){
- alert(prod.a+prod.b)
- }])
- .provider('prod',[function(){
- this.$get=[function(){
- return{
- a:12,b:15
- };
- }];
- }])
- </script>
- </head>
- <bodyng-app='mod'ng-controller='modCtrl'>
- </body>
- </html>
3、service
Service是用"new"关键字实例化的。因此,你应该给"this"添加属性,然后 service 返回"this"。你把 service 传进 controller 之后,在controller里 "this" 上的属性就可以通过 service 来使用了。
- <!doctypehtml>
- <htmllang="en">
- <head>
- <Metacharset="UTF-8">
- <title>Document</title>
- <scriptsrc="angular.min.js"></script>
- <script>
- angular.module('mod',[])
- .service('serv',[function(){
- this.a=12
- }])
- .controller('modCtrl','serv',serv){
- alert(serv.a)
- }])
- </script>
- </head>
- <bodyng-app='mod'ng-controller='modCtrl'>
- </body>
- </html>
4、constant与value
constant不可修饰
- <!doctypehtml>
- <htmllang="en">
- <head>
- <Metacharset="UTF-8">
- <title>Document</title>
- <scriptsrc="angular.min.js"></script>
- <script>
- angular.module('mod',[])
- .constant('VERSION','5.0.3')
- .value('name','cisco')
- .controller('modCtrl','VERSION','name',VERSION,name){
- alert(name+':'+VERSION)
- }])
- </script>
- </head>
- <bodyng-app='mod'ng-controller='modCtrl'>
- </body>
- </html>
5、decorator
- <!doctypehtml>
- <htmllang="en">
- <head>
- <Metacharset="UTF-8">
- <title>Document</title>
- <scriptsrc="angular.min.js"></script>
- <script>
- angular.module('mod',name,prod){
- alert(name+''+prod.nxos+''+prod.type+''+prod.date+''+VERSION)
- }])
- .provider('prod',[function(){
- this.$get=[function(){
- return{
- nxos:'nxos',type:'5548'
- };
- }];
- }])
- .decorator('prod',function($delegate){
- $delegate.date='2007.1.10'
- return$delegate
- })
- </script>
- </head>
- <bodyng-app='mod'ng-controller='modCtrl'>
- </body>
- </html>
