我需要为我的网站提供自动完成建议，并且应该从数据库中检索数据.我想使用 JQuery 自动完成功能.这是我的代码，但它不起作用！这是我的名为 gethint.php 的 php 文件:
I need to to do autocomplete suggestion for my website and the data should be retrieved from database. I want to use JQuery autocomplete. here is my code but it doesn't work! This is my php file with the name of gethint.php:
<?php
require_once ('config.php');
$q=$_REQUEST["q"];
$sql="SELECT `fname` FROM `Property` WHERE fname LIKE '%$q%'";
$result = mysql_query($sql);
$json=array();
while($row = mysql_fetch_array($result)) {
$json[]=array(
'value'=> $row['fname'],
'label'=> $row['fname']
);
}
echo json_encode($json);
?>
然后这是我的 html 文件:
and then this is my html file :
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" />
<script type="text/javascript">
$(document).ready(function(){
$("#hint").autocomplete({
source:'gethint.php',
minLength:1
});
});
</script>
</head>
<body>
<form class="sansserif" action="view.php" method="post">
Name: <input type="text" id="hint" name="hint" >
<input type="submit" name="submit" value="View">
</form>
</html>
花了很多时间，但我找不到问题所在.我想知道是否有人可以帮助我.谢谢.
