list 类型的json数据 

var source =  ["10004","1234","4","3","1.5","0.5"]   
var res= JSON.parse(source );  
res[0]   10004  
res[1]   1234

对象类型的json数据解析

var  source =  {"uid":0,"userId":"124","username":小李","dept_id":"8"};  
var res= JSON.parse(source );  
res["userId"]  124  
res["username"]  小李

构建JSON对象

var ret = [true,false,true,true,true,false,1,2,3,4,101,99];
        var json = JSON.stringify(ret);

举例

var response = {"users":[{"id":1,"nick":"fuck1"}]};
var jsonData = JSON.parse(response);
var data = jsonData["users"];
if(data){
     var len = data.length;
     for(var i=0; i<len; i++){
          var id = data["id"];
     }
}
