Question

这是我的代码： -

<html>
<head>


<script  src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous">

<!-- Latest compiled and minified JavaScript -->
<script  src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
<script>
$( function() {
 var availableTags = [
  "ActionScript",
  "AppleScript",
  "Asp",
  "BASIC",
  "C",
  "C++",
  "Clojure",
  "COBOL",
  "ColdFusion",
  "Erlang",
  "Fortran",
  "Groovy",
  "Haskell",
  "Java",
  "JavaScript",
  "Lisp",
  "Perl",
  "PHP",
  "Python",
  "Ruby",
  "Scala",
  "Scheme"
];
$( "#tags" ).autocomplete({
  source: availableTags
});
} );
$(document).ready(function($) {
alert("js is working");
});
</script>
</head>
<body>
<div class="ui-widget">
 <label for="tags">Tags: </label>
<input id="tags">
</div>
</body>
</html>

它确实给了我警报js正在工作，这意味着我的jquery正在工作，但问题是我的自动完成功能无效。当我检查元素时，我从chrome得到这个错误未捕获的TypeError：$（...）。autocomplete不是一个函数在HTMLDocument。（test.html：41）at j（jquery.min.js：2）at k（jquery.min.js：2）（匿名）@ test.html：41j @jquery.min.js：2k @jquery.min的.js：2

只需在代码中包含以下2行。

<link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
