Question

因此，我决定为以前未设置动画的汉堡菜单设置动画，因此从一开始就没有此问题。

动画从标准汉堡包样式菜单开始，该菜单具有指向首页不同区域的几个链接。单击后，我将菜单动画化，从汉堡包变成x，向访问者指示他们可以通过单击x来关闭菜单。不过，在点击汉堡包菜单中的链接后，我遇到了一个问题，该图标没有从x重置为汉堡包，这弄乱了第二次打开菜单的方式。如果访客再次打开它，则在单击x时x会变成汉堡包，这没有任何意义。

无论如何，我只是想知道是否有办法做到这一点，以便在单击菜单中的链接时，x返回其未打开的汉堡包形式。这是我的代码：

var links = document.querySelectorAll('.menu a');
    var linksLength = links.length

    for(var i = 0; i < linksLength; i++) {
      links[i].addEventListener('click', function() {
        document.getElementById('toggle').checked = false;
      });
    }

    $(document).ready(function(){
	$('.icon').click(function(){
		$(this).toggleClass('open');
	});
});

Answer 1

只需在$(document).ready()函数内部添加此单击处理程序，即可在单击菜单链接之一时从汉堡包图标中删除open CSS类：

    $('.menu a').click(function() {
       $('.icon').removeClass('open');
    });

您也可以通过PURE CSS来

.navigation__checkbox {
    display: none
}

.navigation__button {
    height: 7rem;
    width: 7rem;
    position: fixed;
    top: 1rem;
    left: 1rem;
    border-radius: 50%;
    z-index: 2000;
    box-shadow: 0 1rem 3rem rgba(0, 0, 0, 0.1);
    text-align: center;
    cursor: pointer
}

.navigation__icon {
    position: relative;
    margin-top: 3.5rem;
    user-select: none;
}

.navigation__icon,
.navigation__icon::before,
.navigation__icon::after {
    width: 3rem;
    height: 2px;
    background-color: #333;
    display: inline-block
}

.navigation__icon::before,
.navigation__icon::after {
    content: "";
    position: absolute;
    left: 0;
    transition: all .2s
}

.navigation__icon::before {
    top: -.8rem
}

.navigation__icon::after {
    top: .8rem
}

.navigation__button:hover .navigation__icon::before {
    top: -1rem
}

.navigation__button:hover .navigation__icon::after {
    top: 1rem
}

.navigation__checkbox:checked+.navigation__button .navigation__icon {
    background-color: transparent
}

.navigation__checkbox:checked+.navigation__button .navigation__icon::before {
    top: 0;
    transform: rotate(135deg)
}

.navigation__checkbox:checked+.navigation__button .navigation__icon::after {
    top: 0;
    transform: rotate(-135deg)
}

<div class="navigation">
    <input type="checkbox" class="navigation__checkbox" id="navi-toggle">
    <label for="navi-toggle" class="navigation__button">
        <span class="navigation__icon">&nbsp;</span>
    </label>
</div>
