Question

Bootstrap切换器无法正常工作。该图标是可见的，但在减小浏览器大小后，它不会丢弃链接。我也阅读了其他解决方案，但主要是说在引导之前加载javascript，我尝试在引导程序之前首先加载js，但它仍然没有工作。以下是我正在使用的代码

切换按钮上有一个拼写错误。它应该是data-toggle="collapse"而不是data-toggler="collapse"。

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportContent" aria-expanded="flase" aria-lable="Toggle navigation">
       <span class="navbar-toggler-icon"></span>
</button>

即使将js保持在最佳状态，Bootstrap导航也无法正常工作
