autocomplete+PHP+MYSQL的实现模糊查询

1、HTML网页表单部分：

<input type="text" name="course" id="course" />

2、JS代码部分：

<script type="text/javascript" src="jquery.js"></script>
<script type='text/javascript' src='jquery.autocomplete.js'></script>
<link rel="stylesheet" type="text/css" href="jquery.autocomplete.css" />

<script type="text/javascript">
$().ready(function() {
 $("#course").autocomplete("get_course_list.php", {
  width: 260,
  matchContains: true,
  selectFirst: false
 });
});
</script>

3、PHP 后台部分：

<?php
require_once('Connections/bz_conn.php');
mysql_select_db($database_bz_conn, $bz_conn);
$q = strtolower($_GET["q"]);
$sql = "select *  from  bz_user where  ucompany LIKE '%$q%'";
$rsd = mysql_query($sql);
while($rs = mysql_fetch_array($rsd)){
$ucompany = $rs['ucompany'];
$ucompany=iconv("gb2312","utf-8",$ucompany);  //注意：我的网页、php文件、数据库等 都为GB2312 编码，所以这里转了一下码
 echo "$ucompany\n";
}
?>
