如何销毁数据表？

Question

我使用的数据表,并使用自举-daterangepicker以选择数据将在数据表中所示是一个范围.

它工作正常.

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.但是由于该表已经被创建,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

要使用DOM元素完全删除和删除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:

"bDestroy" : true,

然后,只要您想"重新创建"表,它就不会丢失错误

PS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您的需要进行调整

 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
 * @enInfo           Boolean value to show or not the records info
 * @autoWidth        Boolean value to enable or not table autowidth
 * @enTblTools       Boolean value to enable or not the table tools addin

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文档).

// 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();
