经过昨天我这边糟糕的沟通和不清楚的问题，我准备了一些东西。我是第一次参加这样的论坛。这很艰难，但很好！我意识到这个论坛里的人是多么的专业。我知道没有一个论坛能接近你的信息质量！
我不是一个甜言蜜语的人，这是事实！问题是：
我连接到一个mysql表，但我不能转到下一行、下一行和下一行，以前的记录也是如此。我还是不太明白。这个代码出了什么问题？我真的很想知道它。
当我点击上一个来"未定义的对象。"
当我跳过下一个时，只出现一个记录，然后它就冻结了。我想我在桌子的尽头。
我在这里读了很多帖子，至少有50篇，但我没有得到。我只是不明白。

我不使用jquery命令。我只使用json解析来获取数据，但我得到的不多；）
这是非常基本的。我想做的就是获取上一行和下一行。总是只有一行。+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

我在某种程度上更改了所有文件。因此，请在您的代码中进行相应的修改。并从下一次开始进行正确的编码。
您添加验证，如如果是最后一行，禁用NEXT按钮，如果是第一行，禁用PREV按钮。我解决了你的问题。
谢谢！
