单击时，Bootstrap下拉列表无法在移动设备上运行
[英]Bootstrap dropdown not working on mobile on click
问题描述
我在我的网站上添加了一个下拉菜单，但当导航栏折叠时，它在移动设备上无法正常工作。 当我点击下拉列表时，它会关闭导航栏，而不是显示下拉列表下的项目。
.dropdown-submenu { position: relative; } .dropdown-submenu .dropdown-menu { top: 0; left: 100%; margin-top: -1px; }

这是你在找什么？ 带有子菜单的导航栏
(function($) { $(document).ready(function() { $('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) { event.preventDefault(); event.stopPropagation(); $(this).parent().siblings().removeClass('open'); $(this).parent().toggleClass('open'); }); }); })(jQuery);
.dropdown-submenu { position: relative; } .dropdown-submenu>.dropdown-menu { top: 0; left: 100%; margin-top: -6px; margin-left: -1px; -webkit-border-radius: 0 6px 6px 6px; -moz-border-radius: 0 6px 6px 6px; border-radius: 0 6px 6px 6px; } .dropdown-submenu>a:after { display: block; content: " "; float: right; width: 0; height: 0; border-color: transparent; border-style: solid; border-width: 5px 0 5px 5px; border-left-color: #cccccc; margin-top: 5px; margin-right: -10px; } .dropdown-submenu:hover>a:after { border-left-color: #555; } .dropdown-submenu.pull-left { float: none; } .dropdown-submenu.pull-left>.dropdown-menu { left: -100%; margin-left: 10px; -webkit-border-radius: 6px 0 6px 6px; -moz-border-radius: 6px 0 6px 6px; border-radius: 6px 0 6px 6px; } /* @media (min-width: 768px) { } @media (min-width: 992px) { } @media (min-width: 1200px) { } */

您的script和link标记放在代码段中。 这些标记应放在HTML文件中。 链接标记必须放在head标记中。 我对您的问题进行了编辑，认为您犯了一个错误，但将这些标记放在他们所属的位置可以达到预期的效果：
.dropdown-submenu { position: relative; } .dropdown-submenu .dropdown-menu { top: 0; left: 100%; margin-top: -1px; }
