动态表的唯一ID [英] unique id for dynamic table

问题描述

我将使用从MySQL提取的数据来生成HTML表.MySQL表中的行数不是固定的.

I will be generating a HTML table with data pulled from MySQL.The number of rows in my MySQL table are not fixed.

<?php
  while($row=mysql_fetch_assoc($result))
  { ?>
    <tr>
      <td><?php echo $row['col1'];?></td>
      <td><?php echo $row['col2'];?></td>
    </tr>
  <?php } ?>

现在如何为表行和 table data 元素分配唯一的 id ??

Now how do I have the table rows and table data elements assigned unique id ??

由于行数不固定，我无法为新循环设置退出条件，因此无法生成另一个循环.

Another loop to generate them won't work as I can't set an exit condition for the new loop as number of rows are not fixed.

请指导我如何进行此操作.我只能使用 Javascript ，不能使用 JQUERY .

Please guide me as to how to go forward about it. I can only use Javascript and not JQUERY.

推荐答案

为什么不能做这样的事情?

Why can't you do something like this ?

<?php
  $i = 1;
  while($row=mysql_fetch_assoc($result))
  { ?>
    <tr id="row<?php echo $i;?>">
      <td id="cell-left-<?php echo $i;?>"><?php echo $row['col1'];?></td>
      <td id="cell-right-<?php echo $i;?>"><?php echo $row['col2'];?></td>
    </tr>
  <?php
     $i++;
   } ?>

请注意，我自己添加了编号 row ， cell-left-和 cell-right-.您可以根据自己的要求进行更改.

Please note, I have added ids row, cell-left- and cell-right- by myself. You may change them as per your requirements.
