【问题描述】：

我想使用this 示例所以创建follow html 页面：

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap 101 Template</title>

    <!-- Bootstrap -->
    <link href="css/bootstrap.min.css" rel="stylesheet">
    <script src="js/typeahead.bundle.js"></script>
    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
    <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
    <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
    <![endif]-->
    <script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
    <script src="http://cdn.datatables.net/1.10.4/js/jquery.dataTables.min.js"></script>

    <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

    <!-- Include all compiled plugins (below), or include individual files as needed -->
    <script src="js/bootstrap.min.js"></script>
  </head>
  <body>
    <div id="the-basics">
    <input class="typeahead" type="text" placeholder="States of USA">
    </div> 
    <script type="text/javascript">
      var substringMatcher = function(strs) {
    return function findMatches(q, cb) {
    var matches, substrRegex;

    // an array that will be populated with substring matches
    matches = [];

    // regex used to determine if a string contains the substring `q`
    substrRegex = new RegExp(q, 'i');

    // iterate through the pool of strings and for any string that
    // contains the substring `q`, add it to the `matches` array
    $.each(strs, function(i, str) {
    if (substrRegex.test(str)) {
    // the typeahead jQuery plugin expects suggestions to a
    // JavaScript object, refer to typeahead docs for more info
    matches.push({ value: str });
    }
    });

    cb(matches);
    };
    };

    var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
    'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',
    'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana',
    'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota',
    'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire',
    'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota',
    'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island',
    'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont',
    'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'
    ];

    $('#the-basics .typeahead').typeahead({
    hint: true,
    highlight: true,
    minLength: 1
    },
    {
    name: 'states',
    displayKey: 'value',
    source: substringMatcher(states)
    }); 
    </script>
  </body>
</html>

并从官方引导网站下载所有链接文件，typeahead.bundle.min.js 来自here 和其他文件。但我得到了跟随错误

Uncaught TypeError: Cannot read property 'isArray' of undefined
Uncaught TypeError: undefined is not a function

你能帮我如何使用这个例子吗？

【解决方案1】：

您的问题是加载 JS 库的顺序。

放

<script src="js/typeahead.bundle.js"></script>

之后

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

或之后

<script src="js/bootstrap.min.js"></script>

无论哪种方式都可以解决您的问题。

非常感谢，您能告诉我为什么 CSS 不起作用吗？现在我有一个简单的文本框，而不是引导文本框。
没问题。引导 css 文件实际上是否在您的项目 css 文件夹中？
是的，但是 bootstrap.min.css 中没有 typeahead 类。我也尝试从 stackoverflow.com/questions/18059161/… 复制 typeahead 类，但仍然无法正常工作。再次感谢...
