如何解析json(对象嵌套)
{"RESPONSE":{"DESCRIPTION":"OK","SERIAL_NO":"0","CODE":"CLM_OK"},"DATA":{"NAME":"ssss","LOYALTY_LIST":[{"MODIFY_DATETIME":"20110301","GROUP_ID":"A","SUB_ISSUER":"000010","CARD_TYPE":"0","REMARK3":[],"MEMBER_STATUS":"2","CARD_SUB":"1","SV_CARD":[],"APPLY_DATETIME":"20110301","STATUS":"8","CARD_OLD":[],"CAUSE":[],"MASTER_LOYALTY_ID":"95520000100023220000","SUSPEND_DATE":"20130301","CARD_BTYPE":"0","MERCHANTGROUP_ID":"00000010","MAST_NAME":"小兰","MAST_MEMBER_ID":"A","CREATE_DATETIME":"20110301","LOYALTY_ID":"95520000100023210000"},{"MODIFY_DATETIME":"20110301","GROUP_ID":"A","SUB_ISSUER":"000010","CARD_TYPE":"0","REMARK3":[],"MEMBER_STATUS":"2","CARD_SUB":"1","SV_CARD":[],"APPLY_DATETIME":"20050120","STATUS":"8","CARD_OLD":[],"CAUSE":[],"MASTER_LOYALTY_ID":"95520000100023240000","CARD_BTYPE":"0","SUSPEND_DATE":"20130301","MERCHANTGROUP_ID":"00000010","MAST_MEMBER_ID":"A","MAST_NAME":"小兰","LOYALTY_ID":"95520000100023240000","CREATE_DATETIME":"20050127"}]}}

------解决方案--------------------
直接js解析可以用eval()函数，不过推荐使用jquery，eval有浏览器兼容的问题。

js:
var val=eval("("+data+")");
alert(val.RESPONSE);

jquery:
$.getJSON("路径","参数",function(data){
alert(data.RESPONSE);
});
------解决方案--------------------
你知道所有的key值，下一个json的支持包
import net.sf.json.*;

之后

有现成的函数（一堆get各种value）。。

直接就能得到你想要的值。。。
