Detail: jquery 1.9 above not allow element.size() funtion, instead use .length
Solution: replace .size() to .length
or : this is will return length not change code
$.fn.size = function() {
return this.length;

Có nhiều cách làm trên internet nhưng bị lỗi, khó hiểu
Cách làm đơn giản nhất là replace string json
myArray = {oldKey1: 'value1', oldKey2: 'value2', another: '1'}
Change oldKey1 = newKey1
/*Object to string*/
var jsonMap = JSON.stringify(myArray);
/*Key replace by newkey*/
var jsonMapReplace = jsonMap.replace(oldKey1,newKey1);
/*string to JSON again*/
myArray = JSON.parse(jsonMapReplace);
