var json={"memo":"{"\\u57ce\\u5e02":"\\u5317\\u4eac","\\u8054\\u7cfb\\u7535\\u8bdd":"999","\\u5730\\u5740":"\\u8bf4\\u8bf4\\u51e0\\u53f7\\u653e\\u5047\\u554a","\\u90ae\\u7bb1":"jiangjie2012@gmail.com","\\u7b80\\u4ecb":"\\u8bf4\\u8bf4\\u51e0\\u53f7\\u653e\\u5047\\u554a","\\u7ecf\\u8425\\u8303\\u56f4":"\\u5a5a\\u5e86"}","name":"\u5a5a\u793c\u7eaa","user_id":24,"logo_path":"merchant_logo/101376049270.jpg","license_path":"image_license/101376049270.jpg","city":"\u5317\u4eac","email":"jiangjie2012@gmail.com","pid":1};
json.memo=eval('('+json.memo+')');
alert(json.memo['简介']);
alert(JSON.stringify(json.memo));
