如何通过 Javascript 在此 HTML 中传递 src 值
我已将代码粘贴到
<https://pastebin.com/z8q5cavm>
我将在数据表中有大量行列表，每一行都有一个特定的 href 或 mp3 文件链接。然而，代码总是打开 serm.mp3，即使我在链接中传递了任何内容。
有人可以帮我解决这个javascript吗？

由于您已将 src 值硬编码为 serm.mp3，因此您得到了它。您需要添加以下脚本，以使用您发送到模态的数据值。 <script> $('#exampleModal').on('show.bs.modal', function(e) { var value = e.relatedTarget.dataset.value; $('audio').attr('src', value); }); </script>这是演示。<!DOCTYPE html><html> <head> <title>Test</title> <meta charset="utf-8"> <link rel='manifest' href='/manifest.json'> <link rel="stylesheet" src="style.css"> <link rel="icon" type="image/png" href="icon1.png" /> <link rel='manifest' href='/manifest.json'> <meta name="theme-color" content="#ffffff"> <meta name="apple-mobile-web-app-status-bar" content="#ffffff" > <meta name="viewport" content="width=device-width, initial-scale=1.0"><!--mobile icons--><link rel='shortcut icon' type='image/x-icon' href="images/icon.png" /><link rel="apple-touch-icon" sizes="74x74" href="images/icon-74.png" /><link rel="apple-touch-icon" sizes="96x96" href="images/icon-96.png" /><link rel="apple-touch-icon" sizes="144x144" href="images/icon-144.png" /><link rel="apple-touch-icon" sizes="384x384" href="images/icon-384.png" /><link rel="apple-touch-icon" sizes="512x512" href="images/icon-512.png" /> <link href="https://fonts.googleapis.com/css?family=Montserrat:400,700|Oxygen:400,700" rel="stylesheet"> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/ekko-lightbox/5.3.0/ekko-lightbox.css"> <link rel="stylesheet" href="css/animate.css"> <link rel="stylesheet" href="css/owl.carousel.min.css"> <link rel="stylesheet" href="css/jquery.fancybox.min.css"> <link rel="stylesheet" href="fonts/ionicons/css/ionicons.min.css"> <link rel="stylesheet" href="fonts/fontawesome/css/font-awesome.min.css"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script> <!-- Theme Style --> <link href="http://vjs.zencdn.net/4.12/video-js.css" rel="stylesheet"> <script src="http://vjs.zencdn.net/4.12/video.js"></script> <link rel="stylesheet" href="css/style.css"> <link rel="stylesheet" href="https://cdn.datatables.net/1.10.21/css/jquery.dataTables.min.css"> <link rel="stylesheet" href="../../extensions/Editor/css/editor.dataTables.min.css"> <link rel="stylesheet" href="https://cdn.datatables.net/select/1.3.1/css/select.dataTables.min.css"> <link rel="stylesheet" href="https://cdn.datatables.net/buttons/1.6.2/css/buttons.dataTables.min.css"> <link rel="stylesheet" href="https://cdn.datatables.net/1.10.21/css/jquery.dataTables.min.css"> <link rel="stylesheet" href="https://cdn.datatables.net/colreorder/1.5.2/css/colReorder.dataTables.min.css"> <link rel="stylesheet" type="text/css" href="DataTables/datatables.min.css"/> <script type="text/javascript" src="DataTables/datatables.min.js"></script> <style> a.buttons-collection { margin-left: 1em;
