6.             case \'array\':  
7.                 return \'[\' + obj.map(THIS.jsonToString).join(\',\') + \']\';  
8.             case \'object\':  
9.                  if(obj instanceof Array){  
10.                     var strArr = [];  
11.                     var len = obj.length;  
12.                     for(var i=0; i<len; i++){  
13.                         strArr.push(THIS.jsonToString(obj[i]));  
14.                     }  
15.                     return \'[\' + strArr.join(\',\') + \']\';  
16.                 }else if(obj==null){  
17.                     return \'null\';  
18.   
19.                 }else{  
20.                     var string = [];  
21.                     for (var property in obj) string.push(THIS.jsonToString(property) + \':\' + THIS.jsonToString(obj[property]));  
22.                     return \'{\' + string.join(\',\') + \'}\';  
23.                 }
