用Jsonp輸出數據

頁面輸出的格式如下(3條數據)：

json1246574([{"site_Id":"E001","group_Id":"11","id":"4","parentId":"1","sm_Career":"4","sm_CountryID":"3","sm_Level":"120","sm_PlayerName":"TJ春哥","sm_UID":"11259595285420516","sm_UpState":"4","sm_UpdateTime":"1264236590","sm_officeRankBase":"91"}],

[{"site_Id":"E001","group_Id":"11","id":"3","parentId":"1","sm_Career":"1","sm_CountryID":"3","sm_Level":"120","sm_PlayerName":"TJ卡耐基","sm_UID":"11001897265572627","sm_UpState":"5","sm_UpdateTime":"1264236028","sm_officeRankBase":"95"}],

[{"site_Id":"E001","group_Id":"11","id":"2","parentId":"1","sm_Career":"3","sm_CountryID":"2","sm_Level":"120","sm_PlayerName":"天邊飛羽","sm_UID":"11001897304015173","sm_UpState":"3","sm_UpdateTime":"1264179528","sm_officeRankBase":"36"}])
