Question

试图弄清楚这一个几个小时，没有运气。根据firebug的确切错误是：TypeError：items [0]为null http://localhost:81/tab/resources/jquery-ui.js 第8488行

，代码是：

<html>
<head>
<link rel="stylesheet" href="resources/jquery-ui.css">
<script src="resources/jquery-3.1.1.js"></script>
<script src="resources/jquery-ui.js"></script>
  <script>
  $(function() {
    $( "#skills" ).autocomplete({
      source: 'search.php',
      minLength: 3
    });
  });
  </script>
</head>
<body>

<div class="ui-widget">
<label for="skills">Skills: </label>
<input id="skills">
</div>
</body>
</html>

的search.php：

<?php
require("db.php");

$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);

$key = $_GET['term'];
$query = mysqli_query($connection, "SELECT * FROM sz55 WHERE name LIKE '%{$key}%' AND ejszakak BETWEEN 1 AND 100");
while($row = mysqli_fetch_assoc($query)) {
    $data[] = $row['name'];
}

echo json_encode($data);

mysqli_close($connection);
?>

请帮助：D

事实证明，问题是我的数组中有特殊字符来自查询。只需添加mysqli_set_charset（$ connection，“utf8”）;到search.php解决了这个问题。

jQuery自动完成不断给出TypeError
