cocos creator问题整理

1. hasOwnPropery失效

var o = {
    "id": 1
};    
console.log(o.hasOwnPropery("id"));

错误信息

Hall.js:38 Uncaught TypeError: o.hasOwnPropery is not a function
    at callback (Hall.js:38)
    at XMLHttpRequest.xhr.onreadystatechange (Http.js:29)

不知道为什么不行, 后来改用

var o = {
    "id": 1
};    
console.log("id" in o);
