代码由3块实现:

1.Ui

mvc5的解释就是定义项目,定义模块,定义基本视图

开发遇到以下几个问题:

1.Post提交的data数据是什么格式了?

JQ:$.post("url",data"")

Ang:$http.Post(data:"",params:"")

 

2.$scope.model获取前台传来的Json的取值问题

$http.get(url).success(function(data){

   $scope.model = data;

})

json为集合:{"obj":[{id:1,name:"zzj"},{id:1,name:"zzj"}]},使用就是:$scope.model.obj[0].id,$scope.model.obj[0].name

json为对象:{id:1,name:"zzj"},使用的时候就是  $scope.model.id, $scope.model.name

 

3.路由器配置问题

http://www.runoob.com/angularjs/angularjs-routing.html

 

4.json转obj,string的细节(json检验网:http://www.bejson.com/)

json有2种:对象、集合

对象:{key:value,key:value}

集合:{object:[{key:value},{key:value}]}

 

 格式之间的互转:

在Firefox,chrome,opera,safari,ie9,ie8等高级浏览器直接可以用JSON对象的stringify()和parse()方法。

JSON.stringify(obj)将JSON转为字符串。

JSON.parse(string)将字符串转为JSON格式;

Angular.fromJson( data );

Angular.toJson(data);
