我正在嘗試為輸入框提前輸入。為此，我正在使用typeahead.js 。我正在使用相同的代碼來學習此功能。雖然我沒有收到任何錯誤，但它沒有顯示建議。我還包含了所有需要的腳本，如下所示：<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-3-typeahead/4.0.2/bootstrap3-typeahead.min.js"></script>  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />  <script src="the-basics.js"></script>Html 如下：<div class="container"><div id="the-basics">  <input class="typeahead" type="text" placeholder="States of USA"></div>  </div>js如下：var substringMatcher = function(strs) {console.log('strs', strs);return function findMatches(q, cb) {  console.log('q', q);  var matches, substringRegex;  // an array that will be populated with substring matches  matches = [];  console.log('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)) {      matches.push(str);    }  });    console.log('matches', matches);  cb(matches);};};    var states = ['Alabama', 'Alaska', 'Arizona', 'California',    'Colorado', 'Connecticut', 'Delaware', 'Florida'  ];    $('#the-basics .typeahead').typeahead({    hint: true,    highlight: true,    minLength: 1  },  {    name: 'states',    source: substringMatcher(states)  });請幫我解決這個問題。
