Question

我想从外部页面链接打开bootstrap 4的特定选项卡。

 <script src="assets/bootstrap/js/bootstrap.min.js"></script>
</body>
</html>

我在我的页面中使用bootstrap 4。

Answer 1

您只需将以下代码添加到index.html页面的底部：

<script>
    jQuery(document).ready(function ($) {
        let selectedTab = window.location.hash;
        $('.nav-link[href="' + selectedTab + '"]' ).trigger('click');
    })
</script>

Answer 2

我使用了您的所有代码，并在index.html页面的底部添加了一个小脚本。但是我不知道这个/css/styles.css文件是什么，因此我忽略了它。

这段代码工作正常，没有错误。

nav.html页面：

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>

<a href="index.html#tab-1">tab 1</a>
<a href="index.html#tab-2">tab 2</a>
<a href="index.html#tab-3">tab 3</a>
