单击时如何关闭叠加层锚点链接菜单？

我的问题是，当我打开汉堡菜单并单击导航链接时，确实将我带到了锚链接部分，但重叠式导航菜单却没有关闭！

我确实尝试过关闭CSS类并将类切换到jquery导航，但是它也不起作用。

我的HTML代码是：

$(document).ready(function() {
  $('#toggle').click(function() {
    $(this).toggleClass('active');
    $('#fullnav').toggleClass('open');
  });
});

$(document).ready(function() {
  $('.hamburger-menu').click(function() {
    $(this).toggleClass('change');
  })
});
.fullnav {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #333333;
  z-index: 100;
  visibility: hidden;
  -webkit-transition: opacity .35s, visibility .35s, height .35s;
  transition: opacity .35s, visibility .35s, height .35s;
  overflow: hidden;
}

.hamburger-menu {
  width: 45px;
  height: 35px;
  position: fixed;
  top: 40px;
  right: 50px;
  display: flex;
  flex-direction: column;
  justify-content: space-between;
  cursor: pointer;
  z-index: 500;
}

.line {
  width: inherit;
  height: 5px;
  background-color: #7A7A7A;
  border-radius: 25px;
  transform-origin: right;
  transition: transform .5s;
}

.line-2 {
  height: 3px;
}

.change .line-1 {
  transform: translate(-4px, -4px) rotateZ(-45deg);
}

.change .line-2 {
  opacity: 0;
}

.change .line-3 {
  transform: translate(-4px, -3px) rotateZ(45deg);
}

.fullnav.open {
  opacity: 1;
  visibility: visible;
  height: 100%;
}

.fullnav.close {
  opacity: 0;
  visibility: visible;
  height: 0%;
}

.fullnav.open li {
  -webkit-animation: fadeInRight .5s ease forwards;
  animation: fadeInRight .5s ease forwards;
  -webkit-animation-delay: .35s;
  animation-delay: .35s;
}

.fullnav.open li:nth-of-type(2) {
  -webkit-animation-delay: .4s;
  animation-delay: .4s;
}

.fullnav.open li:nth-of-type(3) {
  -webkit-animation-delay: .45s;
  animation-delay: .45s;
}

.fullnav.open li:nth-of-type(4) {
  -webkit-animation-delay: .50s;
  animation-delay: .50s;
}

.fullnav nav {
  display: flex;
  align-items: center;
  justify-content: center;
  position: relative;
  top: 50%;
  -webkit-transform: translateY(-50%);
  transform: translateY(-50%);
  font-size: 3rem;
  font-family: Montserrat-Light;
  font-weight: 400;
  line-height: 7rem;
  text-align: center;
}

.fullnav ul {
  list-style: none;
  padding: 0;
  margin: 0 auto;
  display: inline-block;
  position: relative;
  height: 100%;
}

.fullnav ul li {
  display: block;
  height: 25%;
  height: calc(100% / 4);
  min-height: 50px;
  position: relative;
  opacity: 1;
}

.fullnav ul li a {
  display: block;
  position: relative;
  color: #FFF;
  text-decoration: none;
  overflow: hidden;
}

.fullnav ul li a:hover:after,
.fullnav ul li a:focus:after,
.fullnav ul li a:active:after {
  width: 100%;
}

.fullnav ul li a:hover::before,
.fullnav ul li a:focus::before,
.fullnav ul li a:active::before {
  width: 100%;
}

.fullnav ul li a:after {
  content: '';
  position: absolute;
  bottom: 0;
  left: 50%;
  width: 0%;
  -webkit-transform: translateX(-50%);
  transform: translateX(-50%);
  height: 3px;
  background: #FFF;
  -webkit-transition: .35s;
  transition: .35s;
}

此代码无法关闭重叠式导航菜单。请帮我解决它：

$(document).ready(function () {
$('fullnav').hide();

 });

将click事件处理程序绑定到链接。在此偶数处理程序中，删除定义菜单打开状态的类。

$("#toggle").click(function() {
  $(this).toggleClass("active");
  $("#fullnav").toggleClass("open");
});

$(".hamburger-menu").click(function() {
  $(this).toggleClass("change");
});

$("#fullnavMenu a").on("click", function() {
  $(".hamburger-menu").removeClass("change");
  $("#toggle").removeClass("active");
  $("#fullnav").removeClass("open");
});
.fullnav {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #333333;
  z-index: 100;
  visibility: hidden;
  -webkit-transition: opacity .35s, visibility .35s, height .35s;
  transition: opacity .35s, visibility .35s, height .35s;
  overflow: hidden;
}

.hamburger-menu {
  width: 45px;
  height: 35px;
  position: fixed;
  top: 40px;
  right: 50px;
  display: flex;
  flex-direction: column;
  justify-content: space-between;
  cursor: pointer;

}

.change .line-2 {
