ajax数据返回进行遍历的实例讲解

{"receiveList":[{"receive_dept_id":"1007873","receive_dept_desc":"区公司领导","guid":"2016112316042622494230","receive_platform_id":"001"},{"receive_dept_id":"1007876","receive_dept_desc":"主任","guid":"2016112316042626240391","receive_platform_id":"001"}]}

$.ajax({

url:"/moduleAuthen/default.do?method=loadAllReceive",

dataType:"json", //返回的数据是json 格式

data：$("#fom1").serialize, //提交id为form1的所有参数

success:function(data){

var json =data.receiveList;

//第一种方式的遍历

 for(var index in json){

 //其实index 就是个索引

 var guid =json[index].guid;

 var receive_dept_desc =json[index].receive_dept_desc;

}

//还有一种jquery 方式的遍历，效果其实是一样的，拿到后台返回我们的数据，我们就可以进行各种操作了。

$.each(json,index){

 var guid =json[index].guid;

 var receive_dept_desc =json[index].receive_dept_desc;

}

}

})
