我可以使用服务器端来填充数据表和其他工作，但单击reload_tableelement.clear 数据表后我无法刷新数据。清除数据表工作正常，但绘制不工作。

查询：

$('#reload_table').live('click',function(){
   oTable_topics.fnReloadAjax(oTable_topics.fnSettings());
   oTable_topics.fnClearTable();
   oTable_topics.fnDraw();
    $.ajax({
       url: "server_processing.php",
       success: function() {
           // if it worked, ask datatable to redraw the table with the new data
           $("#showTopics").dataTable().fnDraw();
           // if this js function does anything useful (like deleting the row), then call it:
           Success();
       },
       error: function() {
           // display any error (like server couldn't be reached...), or at least try to log it
       }
    });
});
oTable_topics =$('#showTopics').dataTable({
        "bLengthChange": false,
        "iDisplayLength": 12,

            clickRowHandler_topics();
            if ( oSettings.aiDisplay.length == 0 )
            {
                return;
            }                       
            var nTrs = $('tbody tr', oSettings.nTable);
            var iColspan = nTrs[0].getElementsByTagName('td').length;
            var sLastGroup = "";
            for ( var i=0 ; i<nTrs.length ; i++ )
            {
                var iDisplayIndex = oSettings._iDisplayStart + i;
                var sGroup = oSettings.aoData[ oSettings.aiDisplay[iDisplayIndex] ]._aData[0];
                if ( sGroup != sLastGroup )
                {
                    var nGroup = document.createElement( 'tr' );
                    var nCell = document.createElement( 'td' );
                    nCell.colSpan = iColspan;
                    nCell.className = "group";
                    nCell.innerHTML = sGroup;
                    nGroup.appendChild( nCell );
                    nTrs[i].parentNode.insertBefore( nGroup, nTrs[i] );
                    sLastGroup = sGroup;

我一直在使用 fnReloadAjax 加载新数据并使用 fnLengthChange 来更改页面长度。

oTable.fnClearTable(0);
oTable.fnReloadAjax('/' + myLocation + '/' + myCustomerId);
oTable.fnLengthChange(pageLength);
