Bootstrap : 导航栏在我们点击时没有关闭，响应问题

Question

我在响应时隐藏导航栏时遇到了一些问题。

当我们点击按钮时，导航栏不会每次都关闭..

如果有人能帮助我，我正在进行 Angular 9 项目。

我真的不知道如何解决这个问题

Answer 1

你需要找到为什么你的 aria-expanded="false" 即使你点击它也保持为真。检查您的网站，您可以看到所有类都在变化，但 aria-expanded 正在从 true 变为 true... 然后所有类返回 true 而不是 false。

无论如何，如果我是你，我会在 Angular 上将这些库之一与 bootstrap 一起使用，以避免此类问题。

Ng bootstrap

Ngx bootstrap
