javascript的eval方法来处理action层传回的json字符串成javascript对象

对于这么一个正常的字符串data：
{"id":1111,"parentDetailId":null,"detailCode":"1111","detailName":"小樱","detailLevel":null,"detailCarrCode":null,"detailCarrName":null,"keepDateCode":null,

"keepDateName":null,"deliverDeptCode":null,"deliverDeptName":null,"saveSite":null,

"deliverRound":null,"verifyRound":null,"shelfRound":null,"shelfType":null,"batchFlag":null,

"detailTBNM":null,"createDTTM":null,"createId":null,"templateUrl":null,"fieldList":null}


转成javascript对象，
方法：
var aaa = null;
eval("aaa = "+data+";");

或
方法:
var aaa = eval("("+data+")");


或者用jquery-json插件，官网：http://code.google.com/p/jquery-json/
