Question

我有这个html表，其中包含来自mysql的数据库信息：

pkg    | kod    | sek  | tahun  | makmal  | cat  | bil | Netbook |
Bidor  | aaa123 | aeu  | 2012   |   no    | book | 100 |    150  |  edit/delete

当用户点击右侧的href按钮编辑或删除时，用户可以编辑表格中的所有信息，但似乎我的代码无效。有人可以纠正我或教我，因为我还是初学者。

用户点击表格右侧的编辑按钮后，这是我的代码。请帮助我，因为经过很多努力，我仍然无法使它发挥作用。

Answer 1

通过jquery选择器禁用页面加载时的所有文本输入，并使用编辑按钮功能再次启用它们。

允许用户编辑或更新HTML表
