想要在尝试排序数据时触发自定义事件

When the user clicks on a column header to sort, I want to fire my own event. I DO NOT want it to sort. I've been doing research, and don't see a good way to do this.

当用户单击列标题进行排序时，我想启动自己的事件。我不希望它排序。我一直在做研究，但没有找到一个好的方法。

I can bind on the sort event to do my own stuff, but the sort still happens. I don't want this. If I disable sorting, then the sort event never fires, so this does not work either.

我可以绑定到排序事件来做我自己的事情，但是排序仍然会发生。我不希望这样。如果我禁用排序，那么排序事件永远不会触发，所以这也不能工作。

I could disable sort and then try and capture click events on the header, but I was hoping there would be a better way to do this. Anyone have any ideas?

我可以禁用排序，然后尝试捕获页眉上的单击事件，但是我希望有更好的方法。谁有什么好主意吗?

Very easy. You just unbind the click.DT handler and add your own. You dont have to disable sorting.

非常容易。你只是松开了点击。DT处理器，添加你自己的。你不必禁用排序。

example

例子

<table id="example">
<thead>
   <th id="id">ID</th>
   <th id="username">Username</th>
</thead>
<tbody>
    <tr><td>1</td><td>A test</td></tr>
    <tr><td>2</td><td>B test</td></tr>
    </tbody>       
</table>

javascript

$(document).ready(function(){
    //init datatables
    var table = $('#example').dataTable();

    //unbind sort event, prevent sorting when header is clicked
    $('#example th').unbind('click.DT');

    //create your own click handler for the header
    $('#example th').click(function(e) {
        alert('Header '+$(this).attr('id')+' clicked');
        //here you can trigger a custom event
    });

    //if you afterwards want to restablish sorting triggered by a click event 
    //here header "username" from example above
    table.fnSortListener(document.getElementById('username'), 1);
});

Note : There is no dedicated "sort"-event in datatables. Allan Jardine mention it may come in a future version 2. http://datatables.net/forums/discussion/5141/capturing-sort-event-on-table-heading/p1

注意:在datatable中没有专用的“sort”事件。Allan Jardine提到它可能会在未来的版本2中出现。http://datatables.net/forums/discussion/5141/capturing-sort-event-on-table-heading/p1
