如何销毁数据表？

Question

我正在使用datatables并使用bootstrap-daterangepicker选择数据将在数据表格中显示的范围。

工作正常。

问题是当我在daterangepicker中选择一个新范围时，它为我提供了一个回调函数，我可以在其中完成我的工作。 在那个回调函数中，我再次调用Datatables。但是由于该表已经创建，我如何销毁上一个表并在其中显示一个新表？

请帮助。我被卡住了。 ：（

编辑： 我有以下代码：

$(element).daterangepicker({options},
function (startDate, endDate) { //This is the callback function that will get called each time
$('#feedback-datatable').dataTable({
                        "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
                        "sPaginationType": "bootstrap",
                        "oLanguage": {
                            "sLengthMenu": "_MENU_ records per page",
                            "oPaginate": {
                                "sPrevious": "Prev",
                                "sNext": "Next"
                            }
                        },
                        "aoColumnDefs": [{
                            'bSortable': false,
                            'aTargets': [2,4]
                        }],
                        "bAutoWidth": false,
                        "aoColumns": [
                                      {"sWidth": "20%"},
                                      {"sWidth": "15%"},
                                      {"sWidth": "45%"},
                                      {"sWidth": "15%"},
                                      {"sWidth": "5%"}
                                      ]
                    });
}

Answer 1

要完全删除和删除带有DOM元素的datatable对象，您需要：

//Delete the datable object first
if(oTable != null)oTable.fnDestroy();
//Remove all the DOM elements
$('#feedback-datatable').empty();

Answer 2

只需将此参数添加到您的声明中：

"bDestroy" : true,

然后，只要你想重新创造＆＃34;它赢得的表格不会丢失错误

P.S。您可以创建一个函数来获取所需的参数，然后在运行时使用不同的选项重新初始化表。

例如，我在我的程序中使用这个，如果它可以帮助您根据需要调整它

 initDataTable($('#tbl1'), 2, 'asc', false, false, 25, false, false, false, 'landscape', rptHdr);  /* Initialize Table */

/*---------------------- Datatable initialization  --------------------------- */
/*
 * @$table           Table id which be initialized
 * @sortCol          Column number that will be initially sortered 
 * @sorOrder         Ascendant (asc) or Descendant (desc)
 * @enFilter         Boolean value to enable or not the filter option
 * @enPaginate       Boolean value to enable or not the filter option
 * @dplyLength       Number of records contained per page when pagination is enabled

Answer 3

我知道这是一个老问题，但是因为我碰到了类似的问题并解决了它。

以下应该做的伎俩（评论来自DataTable API doc）。

// Quickly and simply clear a table
$('#feedback-datatable').dataTable().fnClearTable();

// Restore the table to it's original state in the DOM by removing all of DataTables enhancements, alterations to the DOM structure of the table and event listeners
$('#feedback-datatable').dataTable().fnDestroy();

Answer 4

对于DataTables 1.10，调用是：

// Destroy dataTable
$('#feedback-datatable').DataTable.destroy();

// Remove DOM elements
$('#feedback-datatable').empty();

Answer 5

对于Google搜索者

我很难设法销毁Datatable，在加载新数据之前清空所有以前的数据，并通过这样做重新初始化Datatable，

if ($.fn.DataTable.isDataTable("#myTbl")) {
      ("#myTbl").DataTable().destroy();
}
$('#myTbl tbody > tr').remove();

...

// Load table with new data and re-initialize Datatable

Answer 6

$('#feedback-datatable').dataTable().fnDestroy();

这应该破坏dataTable，然后你将不得不重新初始化dataTable。

Answer 7

在DataTables 1.10及更高版本上，您可以使用"destroy": true

Answer 8

来自DataTable

var table = $('#myTable').DataTable();
$('#tableDestroy').on( 'click', function () {
table.destroy();
});

从服务器重新加载完整的表格描述，包括列：

var table = $('#myTable').DataTable();
$('#submit').on( 'click', function () {
    $.getJSON( 'newTable', null, function ( json ) {
        table.destroy();
        $('#myTable').empty(); // empty in case the columns change

        table = $('#myTable').DataTable( {
            columns: json.columns,
            data:    json.rows
        } );
    } );
});

希望它会有所帮助
