禁用排除除了第一个之外的每一列 [英] Disable Sorting on every column except the first one

问题描述

我目前正在使用Datatables进行自定义系统，我想禁用每栏的排序，但第一个。

我尝试使用以下代码当我添加以逗号分隔的值时，正常工作

 aoColumnDefs：[
 {'bSortable'：false， 'aTargets'：[1，2，3，4]} 
]，
  

但是我的表格列号因每个文件而异，所以我可以有3个或者12个列，我不想手动添加每个文件的值。

如果我添加的值超过我在一个文件中的列我得到以下错误，执行停止

未捕获TypeError：不能读取属性'className'未定义

那么，有没有办法我可以得到这些索引并将它们传递给函数？ p>

谢谢！

解决方案

您可以添加一个特定的cla ss到您不想排序的TH元素。

 < table> 
< thead> 
< th> 
 ... 
< / th> 
< th class =no-sort> 
 ... 
< / th> 
< / thead> 
< tbody> 
 ... 
< / tbody> 
< / table> 
  

然后，您可以在 aTargets 参数

 aoColumnDefs：[
 {'bSortable'：false，'aTargets' no-sort']} 
]

i'm currently using Datatables for a Custom system and i would like to disable Sort for every column but the first one.

I tried with the following code wich is working fine when i add values separated by comma

"aoColumnDefs": [
    { 'bSortable': false, 'aTargets': [ 1, 2, 3, 4 ] }
],

But my tables column number vary for each individual file so i can have 3 or maybe 12 columns, and i don't want to have to manually add the values for each file.

If i add more values than the columns i have in one file i get the following error, and an execution stop

Uncaught TypeError: Cannot read property 'className' of undefined

So, is there any way i can get those index and pass them to the function?

Thanks!

解决方案

You can add a specific class to the TH element that you do not want to be sortable.

<table>
   <thead>
      <th>
         ...
      </th>
      <th class="no-sort">
         ...
      </th>
    </thead>
    <tbody>
      ...
    </tbody>
</table>

And then you can specify this class in your aTargets parameter.

"aoColumnDefs": [
    { 'bSortable': false, 'aTargets': ['no-sort'] }
]
