我有以下 html。它由 bootstrap 和 css url 文件组成。它有两个 Accordion 项目选项卡。但是打开的时候发现有javascript错误。当我单击 Accordion 时，它不显示答案。有什么错误吗？

最佳答案

该错误告诉您还需要包含 jQuery。 

<script 
  src="https://code.jquery.com/jquery-3.2.1.min.js"
  integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
  crossorigin="anonymous">
</script>

确保在包含 bootstrap.js 脚本之前包含 jQuery

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name = "viewport" content = "width = device-width, initial-scale = 1">
       <!-- Latest compiled and minified CSS -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

    <!-- Optional theme -->

<!-- Included jQuery right before bootstrap.js -->
    <script
      src="https://code.jquery.com/jquery-3.2.1.min.js"
