JS对象序列化成json数据和json数据转化为JS对象的代码

JS对象序列化成json数据：

function Serialize(obj){   
  switch(obj.constructor){   
    case Object:   
      var str = "{";   
      for(var o in obj){   
        str += o + ":" + Serialize(obj[o]) +",";   
      }   
      if(str.substr(str.length-1) == ",")   
        str = str.substr(0,str.length -1);   
       return str + "}";   
       break;   
     case Array:         
       var str = "[";   
       for(var o in obj){   
         str += Serialize(obj[o]) +",";   
       }   
       if(str.substr(str.length-1) == ",")   
         str = str.substr(0,str.length -1);   
       return str + "]";   
       break;   
     case Boolean:   
       return "\"" + obj.toString() + "\"";   
       break;   
     case Date:   
       return "\"" + obj.toString() + "\"";   
       break;   
     case Function:   
       break;   
     case Number:   
       return "\"" + obj.toString() + "\"";   
       break;    
     case String:   
       return "\"" + obj.toString() + "\"";   
       break;     
   }   
 }   
var staff_list_obj  ={};  
var staff_id   = 1001;  
staff_list_obj[staff_id]  = {};  
staff_list_obj[staff_id]["姓名"] = '111';  
staff_list_obj[staff_id]["测试"] = '222';  
alert(Serialize(staff_list_obj));

JS对象序列化为JSON对象的方法二

var $ = $ || {};



/** 
 * 将JS对象序列化为JSON字符串 
 * @param {Mixed} o The variable to decode 
 * @return {String} The JSON string 
 * String json = $.encode(o); 
 */

    return JSON.stringify;

    return I < 10 ? "0" + I : I;
  }, A = {

    "\n" : "\\n",

    } else {

              }
            }
          }
        }
      }
    }
  });
})();

json数据转化为JS对象：

var jsonString={....}/[....];
eval("var obj="+jsonString);
alert(obj);

写道

function evalJSON(json){ 
var obj = null; 
try { 
obj = eval("(" + json + ")"); 
} catch(E){} 

return obj ; 
}
