JQuery數據表按Desc od排序

Question

我正在為表使用JQuery數據表，但是我希望最后一個條目像表中的第一個出現一樣以降序顯示。 嘗試更改PHP MYSQL select語句，但不起作用。 我想，這可以是根據我的需求安排的代碼嗎？ 如果是這樣，任何人都會帶領我如何做到相同？ 謝謝...

<script type="text/javascript" language="javascript" >
        $(document).ready(function() {
            var dataTable = $('#employee-grid').DataTable( {
                "processing": true,
                "serverSide": true,
                "order": [[ 0, "desc" ]],    //add this line
                "ajax":{
                    url :"employee-grid-data.php", // json datasource
                    type: "post",  // method  , by default get

                    error: function(){  // error handling
                        $(".employee-grid-error").html("");
                        $("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
                        $("#employee-grid_processing").css("display","none");

                    }
                }
            } );
        } );

    </script>

注意：假設表格的第一列是某種自動遞增的ID

我認為您應該嘗試這樣做：

$(document).ready(function(){
    $('#employee-grid').DataTable({
        "order": [[ 1, "desc" ]]
    });
});

您需要指定默認的訂單列，如下所示：

var dataTable = $('#employee-grid').DataTable( {
        "order": [[ 1, "desc" ]],
 "processing": true,
                "serverSide": true,
        "ajax":{
            url :"employee-grid-data.php", // json datasource
            type: "post",  // method  , by default get

            error: function(){  // error handling
                $(".employee-grid-error").html("");
                $("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
                $("#employee-grid_processing").css("display","none");

            }
        }
    } );
