我正在使用带有服务器端获取数据的 jquery 数据表,我的问题是当数据表为空时,数据表隐藏表并且不显示,我想在表消息中显示没有任何数据的表,如何使用此选项?
oTable_topics =$('#showTopics').dataTable({
"bLengthChange": false,
"bStateSave": true,
"iDisplayLength": 12,
"bScrollCollapse": true,
"bJQueryUI": true,
"bAutoWidth": false,

"sPaginationType": "full_numbers",
"bProcessing": true,
// "fnCreatedRow": function( nRow, aData, iDataIndex ) {
// $('td:eq(5)', nRow).html("<ul class='styledlist' style='width:80px !important;'><img src='http://localhost/shirazee/UI/images/icons/publish.png' style='border:none;'/></ul>");
// },
"fnDrawCallback": function(oSettings) {
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;
}
}
},

{ "bVisible": false, "aTargets": [ 0 ] }
],
"aaSortingFixed": [[ 0, 'asc' ]],
"aaSorting": [[ 1, 'asc' ]],
"fnServerParams": function ( aoData ) {
aoData.push(

)}
});
function clickRowHandler_topics() {
$('#showTopics tbody tr').bind('click', function () {
var aData = oTable_topics.fnGetData( this );
iId_topics = aData[1];
});
}
