ionic准备之angular基础———服务provider 和 factory和service（9）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body ng-app="myApp">
<div ng-controller="firstController">
<ul>
<li ng-repeat="item in name">{{item}}</li>
</ul>
</div>
</body>
<script src="angular/angular.js"></script>
<script type="text/javascript">
var app=angular.module("myApp",[],function($provide){
/*创建服务factory*/
$provide.factory("myFactory",function(){
var server={};
server.getMessage=function(){
return "this is a message";
}
return server;
});
/*用provider创建服务*/
$provide.provider("myprovider2",function(){
this.$get=function(){
var server={};
server.getMessage=function(){
return "this is provider2";
}
return server;
}
});
});
/*也可以再config中定义服务*/
app.config(function($provide){
/*自定义服务*/
$provide.provider("myProvider",function(){
this.$get=function(){
var server={};
server.getName=function(){
var name={
name:"tanxu",
nickName:"xuxu"
}
return name;
}
return server;
}
});
});
app.controller('firstController',function($scope,$filter,myProvider,myprovider2,myFactory){
//用provider
$scope.name=myProvider.getName();
console.log($scope.name);
$scope.name1=myprovider2.getMessage();
console.log($scope.name1);
//
//用factory
$scope.msg=myFactory.getMessage();
console.log($scope.msg);
});
</script>
</html>
我们可以再config中创建服务，或者在module中直接创建，利用provider创建需要this.get()匿名函数，而factory可以直接返回字符串或者对象，建议基于对象去返回。
那么这样会不会太乱，当然还有更好更直观的创建方式
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body ng-app="myApp">
<div ng-controller="firstController">
<ul>
<li ng-repeat="item in name">{{item}}</li>
</ul>
</div>
</body>
<script src="angular/angular.js"></script>
<script src="service.js"></script>
<script type="text/javascript">
var app=angular.module("myApp",['myService']); //引入服务依赖
/*定义服务*/
app.service("service1",function(){
return {
message:"qwewe"
}
})
/*定义服务，用provider必须使用get方法*/
app.provider("provider1",function(){
this.$get=function(){
return {
message:"q34234324"
}
}
})
/*定义服务*/
app.factory("myfactory",function(){
return {
message:"myfactory"
}
})
/**/
app.controller('firstController',function($scope,service1,provider1,myfactory,getMessageFactory){
console.log(service1);
console.log(provider1);
console.log(myfactory);
/*引入外置文件的服务getMessageFactory*/
console.log(getMessageFactory.getMessage());
});
</script>
</html>
上面案例引入了一个外部的js，该js专用于定义各种服务
/**
* Created by Administrator on 2016/3/28.
*/
var service=angular.module('myService',[]);
service.service('getMessageFactory',function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务";
}
return service;
})
service.service('getMessageFactory1',function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务1";
}
return service;
})
service.service('getMessageFactory2',function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务2";
}
return service;
})
在html中的mudule要记得引入依赖关系，引入依赖之前当然你要确保你的service.js已经引入进页面中来了
