配置:

Steam 4 |更新的 beta 版本和软件包 | macOS Catalina v.10.15.3 | XCode 11.4 测试版 2 | Bootstrap CDN 4.4.1

我无法切换导航栏按钮。我不确定这是否是 Leaf 中的错误。我以正确的顺序实现了 Bootstrap 和 CSS。尝试运行此代码。不要忘记将浏览器窗口的大小调整为移动设备或平板电脑 View 以显示导航栏切换按钮。
这是我的叶子代码:

// base.leaf

#extend("base"):
#export("main"):
<div class="container mt-3">

#endexport
#endextend

在 Safari 的 Inspect 元素中,我的 html 文档以正确的顺序呈现。但是,我不知道为什么单击导航栏切换不起作用。

最佳答案

据我记得使用 Vapor 4 叶渲染器有一个关于 # 的错误。 .它们总是被解释为叶子标签的开始。

最简单的解决方法是使用 \ 转义它们。 : data-target="#navbarCollapse"成为data-target="\#navbarCollapse"
