一般得到的json格式的数据为：

var newRankList=new Array();
newRankList.put({"name":"aaa","password":"123","Id":"1"});
newRankList.put({"name":"bbb","password":"456","Id":"2"});
newRankList.put({"name":"ccc","password":"789","Id":"3"});

按照Id进行排序：

newRankList.sort(function (a,b){return a.Id-b.Id;});

操作jquery中的json数据：

数据：

var data={"status":0,
 "data":{
		　　"rw":{
		　　"7075":　　　　　　{"name":"\u5c0f\u4f1f\u4ed4","vip_level":"X","union_name":"\u5929\u5730\u4f1a","level":"XX","renown":"XXXX","ticket":"0","sum_fpower":"X","trend":0,"rank":1},
　　"7617":　　{"name":"\u5b50\u6602","vip_level":"X","union_name":"\u5929\u5730\u4f1a","level":"XX","renown":"XXXX","ticket":"0","sum_fpower":"XXXXX","trend":0,"rank":2},
　　"923":{"name":"\u8303\u5f0f\u4e4b\u9b42","vip_level":"XX","union_name":"\u96c7\u4f63\u519b","level":"XXX","renown":"XXXX","ticket":"0","sum_fpower":"XXXX","trend":0,"rank":3}}}}

 

获取name的话：

data.data.rw.name

如果是循环的话可以

var list=data.data.rw;
for(var i in list)
{
var name=list[i].name;
var level=list[i].level;
}
