我正在使用数据表插件，因此我正在搜索一个名为“特权”的字段。prvilege 的值是“superadmin”和“admin”。对于通配符搜索，每当我按“管理员”搜索时，都会显示管理员和超级管理员的记录。如何解决这个问题。我的代码是这样的：
function fnFilterColumn ( i )
{
$('#example').dataTable().fnFilter(
$("#col"+(i+1)+"_filter").val(),i,true,false);
}
$(document).ready(function(){
var oTable = $('#example').dataTable( {
"bProcessing": true,
"sAjaxSource": "datatabledb.php",
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"sDom": 'T<"clear">lfrtip',
"oTableTools": {
"aButtons": [
{
"sExtends": "csv",
"sButtonText": "Save to CSV"
}
]
},
"oLanguage": {
"sSearch": "Search all columns:"
},
"aoColumns": [
null,
{ "bSortable": false }, // disable the sorting property for checkbox header
null,null,null,null,null,null,null,null
]
} );
在 datatabledb.php 文件中，我写下了我的数据库代码，例如：
<?php
include('library/function.php');
