我正在通过数据表为我的 php 脚本实现排序和搜索功能。对于排序它的好。对于搜索，我有 3 个文本字段、1 个年龄范围字段和 1 个下拉菜单。下拉框的不同值是“所有者”、“超级管理员”、“管理员”和“代理”。因此，当我选择值“admin”时，记录列表将显示其中包含“admin”和“superadmin”。我可以理解这是在“superadmin”一词中显示的，“admin”一词在那里。所以只有这个下拉框，我怎么能限制确切的词。我的代码是这样的：
<script type="text/javascript" >
(function($) {
$.fn.dataTableExt.oApi.fnGetColumnData = function ( oSettings, iColumn, bUnique, bFiltered, bIgnoreEmpty ) {
// check that we have a column id
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
// set up data array
var asResultData = new Array();
for (var i=0,c=aiRows.length; i<c; i++) {
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>';
}
function fnFilterColumn ( i )
{
$('#example').dataTable().fnFilter(
$("#col"+(i+1)+"_filter").val(),
i
