使jQuery数据表保持搜索/排序时分配的行号 [英] Make jQuery datatables keep the row number assigned when searching/sorting

问题描述

我有以下代码在jQuery Datatables中创建行号：

I've got the following code to create a row number in jQuery Datatables:

"fnRowCallback": function(nRow, aData, iDisplayIndex, iDisplayIndexFull){ 
        var index = iDisplayIndexFull + 1; 
        $('td:eq(0)', nRow).html(index); 
        return nRow;
     },

但是，当我搜索某个值时，行号更新。这是预期的。我的问题是，有没有在最初创建行数后保持不变？

However, when I search for a certain value, the row numbers update. This is expected. My question is, is there anyway to make the row numbers remain the same after they are initially created?

示例：

 Initial output
 1     Team1
 2     Team2
 3     Team3
 4     Team4
 5     Team5

 After Searching
 2     Team2
 5     Team5

这可能吗？ / p>

Is this possible?

推荐答案

"fnDrawCallback": function ( oSettings ) {
 /* Need to redo the counters if filtered or sorted */
 if ( oSettings.bSorted || oSettings.bFiltered )
 {
 for ( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ )
 {
 $('td:eq(0)', oSettings.aoData[ oSettings.aiDisplay[i] ].nTr ).html( i+1 );
 }
 }
 }
