解决方案
应该与你所设置的数字有关，你尝试将08、09、10、11 都加上双引号试试
解决方案二：
去掉前面的0，要不就会当做8进制了，010对应的10进制是8,010对应的是9，键名称重复了导致前面的8,9键值被覆盖了
既然是json对象，你的键名称最好用引号括起
解决方案三：
把你的json内容值拷贝到这个网站：http://www.bejson.com/
格式化一下，看看是不是真的少了一部分内容，通常是不会少内容的，除非你的json格式不正确，少了引号或者但引号。

解决方案四：
008不是一个valid的javascript的identifier。
解决方案五：
var JsonObj = {
name: "bill"
};
这里的name是个语法糖，实际上是"name": "bill"
只有name是个合法的JS的标识符的时候，才能不用引号（所谓的糖语法）
引用时，也可以JsonObj.name这样
但是如果name不是合法的JS的标识符的时候，就必须用引号了
且引用时，只能这样JsonObj["008"]
这是基本的JS的语法规则，可以找资料参考。
解决方案六：
json对象值跟键都要加双引号
