当菜单“关闭”时，导航栏链接仍然可点击但不可见

Question

我正在使用导航栏模板，但我遇到了一个问题，即导航栏链接仍然存在于页面上，并且即使导航栏“关闭”也可以点击。

我正在考虑用脚本更改类，修改现有的类，但实际上我不知道该怎么做。

当导航栏关闭时，隐藏链接或暂时删除链接的最佳方法是什么？

var $header_top = $('.header-top');
var $nav = $('nav');

$header_top.find('a').on('click', function() {
  $(this).parent().toggleClass('open-menu');
});

  a {
  text-decoration: none;
  color: white;

ul,

.clearfix:after {

Answer 1

只需将overflow: hidden 添加到nav 即可修复；

nav {
    overflow: hidden;
}

您已经设置了height: 0 和opacity: 0，但是内容仍然溢出并且它不可见的唯一原因是因为opacity: 0 属性，它只是使它透明，所以它仍然可以点击。

Answer 2

您应该将pointer-events: none 添加到.nav 和pointer-events: auto 到.open-menu ~ nav

自动

元素的行为与pointer-events 属性相同 未指定。在 SVG 内容中，这个值和值 visiblePainted 效果一样。

无

元素永远不是指针事件的target；然而， 指针事件可能以它的后代元素为目标，如果这些后代 将pointer-events 设置为其他值。在这些情况下， 指针事件将触发此父元素上的事件侦听器 在活动期间适合他们往返后代的途中 捕获/bubble 阶段。
