TypeError: $(...).easyAutocomplete is not a function

Question

我正在尝试遵循 jquery easyAutocomplete docs 并收到此错误。我知道这是一个非常常见的问题，并且已经在 SO 中被问过一些。但是 none 似乎消除了我的错误。这是我的代码

test.js

var options = {
  url: "places.json",
  getValue: "name",

  list: {
    match: {
      enabled: true
    }
  },

  theme: "square"
};

$("#textbox").easyAutocomplete(options);

html

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <title>test</title>

    <link
      rel="stylesheet"
      href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/smoothness/jquery-ui.css"
    />
  </head>
  <body>
    <div>
      Location: <br />
      <br />
      <input type="text" name="enterlocation" id="textbox" />
      <button>enter</button>
    </div>
  </body>

  <script src="https://code.jquery.com/jquery-3.4.1.js"></script>
  <script async src="http://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
  <script src="test.js"></script>
</html>

json:

[
  { "name": "Afghanistan", "code": "AF" },
  { "name": "Aland Islands", "code": "AX" },
  { "name": "Albania", "code": "AL" },
  { "name": "Algeria", "code": "DZ" },
  { "name": "American Samoa", "code": "AS" }
]

在EasyAutocomplete guide中，它说：

In order to use EasyAutocomplete, add these files in header section of your page.

<script src="path/to/jquery.easy-autocomplete.min.js"></script> 


<link rel="stylesheet" href="path/to/easy-autocomplete.min.css"> 


<link rel="stylesheet" href="path/to/easy-autocomplete.themes.min.css"> 
Remember to include jQuery file. You can download library from the jQuery website. Best practice is to use CDN server:

<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>

基于此，您需要在 jQuery 之后和您自己的代码之前包含 jquery.easy-autocomplete.min.js。您还应该包括 easy-autocomplete.min.css.
