jquery DataTables - change value of a cell not just display value
提问by Shibbott
Using DataTablesI want to change the value of the data before rendering the table. I used this:
使用DataTables我想在呈现表格之前更改数据的值。我用过这个：
"fnRowCallback": function( nRow, aData, iDisplayIndex ) {
if ( aData[2] == "0" ){
$('td:eq(1)', nRow).html( '<b>6</b>' );
}
}
But I found that although I changed the displayed text to be 0 to 6, when I sort by the column it's still sorting by the data and not the displayed text.
但是我发现虽然我将显示的文本从 0 改为 6，但是当我按列排序时，它仍然是按数据排序，而不是按显示的文本排序。
Does anyone know how I can actually change the data in the cell so that when I sort it will correctly sort by 0-6?
有谁知道我如何实际更改单元格中的数据，以便在排序时按 0-6 正确排序？

You need to update the datatable, not html.
您需要更新数据表，而不是 html。
oTable.fnUpdate( newValue, rowPos, columnPos);
assuming oTableis a reference to the datatable.
假设oTable是对数据表的引用。

You should probably paste some more of your code, especially the sorting area.
您可能应该粘贴更多代码，尤其是排序区域。
It seems you're mixing up val() and html():
看来您正在混淆 val() 和 html()：
This will get you the input or cell value as in the value tag "value=?"
这将为您提供输入值或单元格值，如值标签“value=?”
$("#currentRow").val()
This will get you the actual html (data) between the tag "<td>data</td>"
这将为您提供标签“<td>data</td>”之间的实际 html（数据）
$("#currentRow").html()
