嗨,我正在使用带有multi_filter_select单个列过滤的jquery 数据表插件(与单个列过滤相同,只是它们是选择框)。我有=隐藏的前 2 列,这导致过滤框显示在错误的列下,因为前 2 个过滤框用于隐藏列,将所有内容向下推 2 列。
这是我的代码:
用于单独过滤的 api 函数
(function($) {
/*
* Function: fnGetColumnData
* Purpose: Return an array of table values from a particular column.
* Returns: array string: 1d data array
* Inputs: object:oSettings - dataTable settings object. This is always the last argument past to the function
* int:iColumn - the id of the column to extract the data from
* bool:bUnique - optional - if set to false duplicated values are not filtered out
* bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
* bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array
* Author: Benedikt Forchhammer <b.forchhammer@mind2.de>
*/
$.fn.dataTableExt.oApi.fnGetColumnData = function ( oSettings, iColumn, bUnique, bFiltered, bIgnoreEmpty ) {
// check that we have a column id
// alert(iColumn);
// alert(oSettings);
if ( typeof iColumn == "undefined" ) return new Array();
// by default we only wany unique data
if ( typeof bUnique == "undefined" ) bUnique = true;
// by default we do want to only look at filtered data
if ( typeof bFiltered == "undefined" ) bFiltered = true;
// by default we do not wany to include empty values
if ( typeof bIgnoreEmpty == "undefined" ) bIgnoreEmpty = true;
// list of rows which we're going to loop through
var aiRows;
// use only filtered rows
if (bFiltered == true) aiRows = oSettings.aiDisplay;
// use all rows
else aiRows = oSettings.aiDisplayMaster; // all row numbers
//alert(aiRows);
// set up data array
var asResultData = new Array();
for (var i=0,c=aiRows.length; i<c; i++) {
// alert("inloop");
iRow = aiRows[i];
var aData = this.fnGetData(iRow);
var sValue = aData[iColumn];
// ignore empty values?
if (bIgnoreEmpty == true && sValue.length == 0) continue;
// ignore unique values?
else if (bUnique == true && jQuery.inArray(sValue, asResultData) > -1) continue;
// else push the value onto the result data array
else asResultData.push(sValue);
}
return asResultData;
}}(jQuery));
function fnCreateSelect( aData )
{
var r='<select><option value=""></option>', i, iLen=aData.length;
for ( i=0 ; i<iLen ; i++ )
{
r += '<option value="'+aData[i]+'">'+aData[i]+'</option>';
}
return r+'</select>';
}
这是准备好的文件:
$(document).ready(function() {
var customerId = $("#customer").text();
var fleetT = $('#fleetsTable').dataTable( {
"bProcessing": true,
"bServerSide": false,
"sAjaxSource": "/fleet_processing.php",
"aoColumns": [{"bVisible":false},{"bVisible":false},null,null,null,null,null],
"fnInitComplete": function() {
$("tfoot th").each( function ( i ) {
this.innerHTML = fnCreateSelect( fleetT.fnGetColumnData(i) );
$('select', this).change( function () {
//var realIndex = fleetT.oApi._fnVisibleToColumnIndex( fleetT.fnSettings(), jQuery('tfoot select').index(this));
fleetT.fnFilter( $(this).val(), i);
} );
} );
}
} );
和html:
<table cellpadding="0" cellspacing="0" border="0" class="display" id="fleetsTable">
<thead>
<tr>
<th width="20%">fleet id</th>
<th width="20%">customer id</th>
<th width="20%">Equipo</th>
<th width="25%">Marca y Modelo</th>
<th width="25%">Filter Type</th>
<th width="15%">Model Number</th>
<th width="15%">quantity</th>
</tr>
</thead>
<tbody>
<tr>
<td colspan="5" class="dataTables_empty">Loading data from server</td>
</tr>
</tbody>
<tfoot>
<tr>
<th>fleet id</th>
<th>customer id</th>
<th>Equipo</th>
<th>Marca y Modelo</th>
<th>Filter Type</th>
