我已经搞砸了太久,试图让它工作。任何人都可以看看你是否有任何指示。
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link type="text/css" rel="stylesheet" href="autocomplete.css" />
<script src="jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="jquery-ui-1.8.21.custom.min.js" type="text/javascript"></script>
<title></title>
</head>
<body>
<style>
.ui-autocomplete-loading { background: white url('images/ui-anim_basic_16x16.gif') right center no-repeat; }
</style>
<script>
$(function() {
$( "#materials" ).autocomplete({
source: "autocomplete.php",
minLength: 2
});
});
</script>
<div class="demo">
<div class="ui-widget">
<label for="materials">Materials: </label>
<input id="materials" />
</div>
</div><!-- End demo -->
</body>
</html>
和 php 文件是
require_once "db_con.php"; // Database connection, I know this works.
$q = strtolower($_GET["q"]);
if (!$q)
return;
$sql = "SELECT * FROM materials WHERE name LIKE '%$q%'";
$rsd = mysqli_query($dbc, $sql) or die(mysqli_error($dbc));
while ($rs = mysqli_fetch_array($rsd)) {
$cname = $rs['name']; // I know this all returns correctly
echo json_encode($cname); // First time I have ever used json, error might be here.
}
我正在尝试拥有一个由 Jquery 提供支持的自动完成网页,该网页是使用 PHP 从 mysql 提供的数据。简单的。只是它不起作用...
有人知道我缺少什么吗?

为了检查这是否有效,我完成了以下操作:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link type="text/css" rel="stylesheet" href="autocomplete.css" />
<script src="jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="jquery-ui-1.8.21.custom.min.js" type="text/javascript"></script>
<title></title>
</head>
<body>
<style>
.ui-autocomplete-loading { background: white url('images/ui-anim_basic_16x16.gif') right center no-repeat; }
</style>
<script>
$(function() {
$( "#materials" ).autocomplete({
source: <?php
include_once 'db_con.php';
$sql = "SELECT name FROM materials";
$rsd = mysqli_query($dbc, $sql) or die(mysqli_error($dbc));
echo '[';
while ($rs = mysqli_fetch_array($rsd)) {
echo "'" . $rs['name'] . "', "; //add results to array
}
echo ']';
?>,
minLength: 2
});
});
</script>
<div class="demo">
<div class="ui-widget">
<label for="materials">Materials: </label>
<input id="materials" />
</div>
</div><!-- End demo -->
</body>
</html>
效果很好。太好了,我想我会保留这段代码,而不是它应该如何工作,但是......
