html - 当菜单为 "closed"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，但遇到一个问题，即导航栏链接仍然存在于页面上，并且即使导航栏“关闭”时也可单击。

我正在考虑也许用脚本更改类，修改现有的类，但实际上我不知道该怎么做。

关闭导航栏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,
li {
  list-style-type: none;
}

.clearfix:before,
.clearfix:after {
  content: "";
  display: table;
}

.clearfix:after {
  clear: both;
}

.l-left {
  float: left;
}

.l-right {
  float: right;
}

.end {

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，但内容仍然溢出，并且其不可见的唯一原因是 opacity: 0 属性，这只是使其透明，因此仍然可点击。
