javascript - 下拉菜单中的 Bootstrap 4 选项卡

Question

我正在使用内部带有选项卡的 boostrap 4 下拉菜单。这是密码 我发现此链接对于停止单击事件传播很有用，这样下拉菜单不会在单击其中时关闭 Avoid dropdown menu close on click inside

但是点击标签不起作用。 密码:boostrap 4 tabs inside drop down menu

is there any solution or another approach so that tabs work inside drop down menu

JS

$('.dropdown-menu').on("click.bs.dropdown", function (e) { e.stopPropagation(); e.preventDefault(); });

有没有可能的解决方案？

Answer 1

最简单的方法是将其包装在 form 中，因为该表单会阻止 Dropdown 在单击时关闭...

<nav>
    ...
    <li class="nav-item dropdown">
             <form>
                 <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown">
                      Dropdown link
                 </a>
                 <div class="dropdown-menu">
                     ....
                 </div>
            </form>
    </li>
    ...
</nav>

另一种方法是使用 jQuery 来实现:

$('.dropdown-menu .nav-tabs .nav-link').on("click.bs.dropdown", function (e) { 
    $(this).tab('show'); 
    e.stopPropagation(); 
});
