angularjs框架学了有一段时间了，感觉很好用。可以把angularjs的app理解成php的class，controller是控制器，而内置服务和自定义服务就可以理解成models了。angularjs的内置服务多，例如：$scope,$rootScope,$http,$q,$resource,$routeProvider等等，下面来说一下怎么自定义服务
一，factory,service,provider自定义服务，services.js
'use strict';
/* Services */
var phonecatServices = angular.module('phonecatServices', []);
phonecatServices.factory('facetorytest', ['$window', //factory方式
function($window){
var test = {
firstname:"tank",
lastname:function(){
return "zhang";
}
};
$window.alert('aaaa'); //内置服务可以注入
return test;
}
]);
phonecatServices.service('servicetest', ['$window', //service方式
function($window){
$window.alert('bbbb'); //内置服务可以注入
this.firstname = "tank";
this.lastname = function(){
return "zhang";
}
}
]);
phonecatServices.provider('providertest',[ //provider方式，内置服务不可以注入
function(){
this.test = {
"firstname":"tank",
"lastname":"zhang"
}
this.$get = function () {
return this.test;
};
}
]);
二，controller调用自定义模块，controllers.js
'use strict';
/* Controllers */
var phonecatControllers = angular.module('phonecatControllers', []);
//写过js function的对这种调用方式，很熟悉，服务名称不能变
function TestCtrl($scope,facetorytest,servicetest,providertest) {
$scope.facetorytest = facetorytest.firstname+" "+facetorytest.lastname();
$scope.servicetest = servicetest.firstname+" "+servicetest.lastname();
$scope.providertest = providertest.firstname+" "+providertest.lastname;
}
//这种调用方式根jquery非常的像，服务名称也不能变
phonecatControllers.controller('TestCtrl',function($scope,facetorytest,servicetest,providertest) {
$scope.facetorytest = facetorytest.firstname+" "+facetorytest.lastname();
$scope.servicetest = servicetest.firstname+" "+servicetest.lastname();
$scope.providertest = providertest.firstname+" "+providertest.lastname;
});
//以注入的方式来调用，服务名称可以改变
phonecatControllers.controller('TestCtrl',['$scope',"facetorytest","servicetest","providertest",
function($scope,facetory111,service111,provider111) { //自定义,服务名称
$scope.facetorytest = facetory111.firstname+" "+facetory111.lastname();
$scope.servicetest = service111.firstname+" "+service111.lastname();
$scope.providertest = provider111.firstname+" "+provider111.lastname;
}
]);
三，创建app把上面的service和controller接合到一起。app.js
'use strict';
/* App Module */
var phonecatApp = angular.module('phonecatApp', [
'ngRoute',
'phonecatControllers', //上面定义的controller
'phonecatServices' //上面自定义的服务
]);
四，html中显示
<!doctype html>
<html lang="en" ng-app="phonecatApp">
<head>
<meta charset="utf-8">
<title>Google Phone Gallery</title>
<link rel="stylesheet" href="css/app.css">
<link rel="stylesheet" href="css/bootstrap.css">
<script src="lib/angular/angular.js"></script>
<script src="lib/angular/angular-route.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
<script src="js/services.js"></script>
</head>
<body >
<div ng-controller="TestCtrl">
<p>{{facetorytest}}</p>
<p>{{servicetest}}</p>
<p>{{providertest}}</p>
</div>
</body>
</html>
显示结果：
tank zhang
tank zhang
tank zhang
五，错误纠正
在网上看到，有人说service是不能注入内置服务器的，但是实际操作结果是provider是不能注入内置服务的。我用的angularjs的版本是AngularJS v1.2.14
phonecatServices.provider('providertest',['$window',
function($window){
$window.alert('cccc'); //报错
this.test = {
"firstname":"tank",
"lastname":"zhang"
}
this.$get = function () {
return this.test;
};
}
]);
provider 注入内置服务错误

我也看到过这样的说法，事实是provider不可以注入依赖，而factory和service可以。
