全屏覆盖菜单切换

Full screen overlay menu toggle

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,但不会关闭叠加层。 我试过添加一些 jquery 但我做不到。我试图像点击十字那样切换菜单,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');
});
.container {
  position: absolute;
  width: 100%;
  height: 100%;
  text-align: center;
  top: 40%;
  left: 0;
  margin: 0 auto;
  font-family: 'Roboto', sans-serif;
}
.container p {
  font-size: 20px;
}
.container a {
  display: inline-block;
  position: relative;
  text-align: center;
  color: #FF5252;
  text-decoration: none;
  font-size: 20px;
  overflow: hidden;
  top: 5px;
}
.container a:after {
  content: '';
  position: absolute;
  background: #FF5252;
  height: 2px;
  width: 0%;
  transform: translateX(-50%);
  left: 50%;
  bottom: 0;
  transition: 0.35s ease;
}
.container a:hover:after {
  width: 100%;
}

h1 {
  position: relative;
  text-align: center;
  font-family: 'Vollkorn', sans-serif;
}

.button_container {
  position: fixed;
  top: 5%;
  right: 2%;
  height: 27px;
  width: 35px;
  cursor: pointer;

  transition: opacity 0.25s ease;
}
.button_container:hover {

}
.button_container.active .top {

我在自己这边尝试了这段代码,发现在这种情况下可以做一个小改动。

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

 $(".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。
