【问题描述】：

我想创建一个全屏覆盖菜单。我无法在锚点单击时关闭菜单，例如。如果我们点击主页。它向下滚动到该部分，但不会关闭覆盖。 我尝试添加一些 jquery，但我无法做到。我试图在单击十字时切换菜单，但没有成功。

$('#toggle').click(function () 
  $(this).toggleClass('active');
  $('#overlay').toggleClass('open');
);

$(".fulloverlay a").on("click", function() 
  $('#toggle').toggleClass('active');
  $('#overlay').toggleClass('open');
);

【参考方案1】：

我尝试了这段代码，发现在这种情况下只需做一点小改动。

您正在使用错误的选择器选择锚点(a)。因为'fulloverlay'是父导航元素的ID，所以不要像这样选择它：

 $(".fulloverlay a").on("click", function() 
   $('#toggle').toggleClass('active');
   $('#overlay').toggleClass('open');
);

你可以这样写：

$("#fulloverlay a").on("click", function() 
   $('#toggle').toggleClass('active');
   $('#overlay').toggleClass('open');
);

然后就可以了。

【讨论】：

因此这是一个错字 - 可以这样关闭。
