用jquery&更新列表阿贾克斯 [英] update list with jquery & ajax

问题描述

我用php& jQuery，显示数据库中的每一行.

i make a list with php & jquery which shows every row in my database.

我要向此列表添加一个更新按钮.当用户单击一行时，该行将展开，并且该按钮将变为可见.并且该行上的文本将进入文本框.

i want to add this list an update button. when user clicks on a row, the row will expand and the button will become visible. and the text on that row will go in a textbox.

我的问题是，当用户单击该行中的按钮时，如何更新文本?首先，我想我可以在每一行中放置一个表格..但是我认为这是一个糟糕的解决方案.

and my question is, how can i update the text when user click on the button in that row? first i thought, i could put a form in every row.. but i think that's a terrible solution.

您能为我推荐一个我想做的事的例子或资料吗?

can you suggest me an example or source for what i want to do?

推荐答案

询问代码的问题必须显示您尝试过的代码.由于您没有提供任何代码，因此我将给出一个高级答案:

Questions asking for code must show the code you've tried. Since you didn't give any code, I'll give a high-level answer:

1. 将事件处理程序附加到按钮(或可能实际上附加到表并使用委托).
2. 在事件处理程序中，使用jQuery遍历函数查找按钮所属的行.
3. 一旦您有对该行的引用，请使用jQuery遍历函数在该行中找到input.
4. 获取值并使用ajax更新数据库.

1. Attach an event handler to the button (or probably actually to the table and use delegation).
2. In the the event handler, use jQuery traversal functions to find the row to which the button belongs.
3. Once you have a reference to the row, use jQuery traversal functions to find the inputs in the row.
4. Get the values and use ajax to update the database.
