javascript - 用 JS 关闭汉堡菜单

Question

单击链接时如何关闭我的汉堡包菜单，我需要它进行一页导航。菜单工作正常，但只需要一种关闭它的方法。我对 JS 知之甚少。

我有 HTML 和 CSS，没有任何 JS:

index.html 文件中的 HTML

<nav>
<div id="menuToggle">
    <input type="checkbox"/>
    <span></span>
    <span></span>
    <span></span>

<ul id="menu" class="navbar-collapse">
        <li><a href="#1">idi na 1</a></li>
        <li><a href="#2">idi na 2</a></li>
        <li><a href="#3">idi na 3</a></li>
</ul>
</div>
</nav>

style.css 文件中的 CSS

*{
    margin:0;
    padding:0;
}
nav{
    position:fixed;
    z-index: 99999;
}
a{
    text-decoration: none;
    font-family: 'Lato', sans-serif;
    color: #000000;
    transition: color 0.3s ease;
}
a:hover{
    color: #999999;
}
#menuToggle{
    display: block;

    z-index: 1;
    -webkit-user-select: none;

#menuToggle input{

    opacity 0.55s ease;
}
#menuToggle span:first-child{
    transform-origin: 0% 0%;
}
#menuToggle span:nth-last-child(2){
    transform-origin: 0% 100%;
}
#menuToggle input:checked ~ span{
    opacity: 1;
    transform: rotate(45deg) translate(-2px, -1px);
    background: #000000;
}
#menuToggle input:checked ~ span:nth-last-child(3){
    opacity: 0;
    transform: rotate(0deg) scale(0.2, 0.2);
}
#menuToggle input:checked ~ span:nth-last-child(2){
    opacity: 1;
    transform: rotate(-45deg) translate(0, -1px);
}
#menu{
    background-size:cover;

    background-color: rgba(255,255,255,1);
    list-style-type: none;

    transform-origin: 0% 0%;
    transform: translate(-100%, 0);
    transition: transform 0.5s cubic-bezier(0.77,0.2,0.05,1.0);
}
#menu li{
    padding: 10px 0;
    font-size: 60px;
    text-align: center;
}
#menuToggle input:checked ~ ul{
    transform: scale(1.0, 1.0);
    opacity: 1;
}

@media only screen and (max-width:480px) { 
    #menuToggle input {
        top: 2px;
        left: -5px;
    }
}

非常感谢您提供的任何帮助!

使用触发器。

$('#menu > li > a').on('click', function() {
  $("#menuToggle").find('input').trigger("click");
});

*{
margin:0;
padding:0;
}
nav{
position:fixed;
z-index: 99999;
}
a{
text-decoration: none;
font-family: 'Lato', sans-serif;
color: #000000;
transition: color 0.3s ease;
}
a:hover{
color: #999999;
}
#menuToggle{
display: block;
position: relative;
top: 50px;
left: 50px;
z-index: 1;
-webkit-user-select: none;
user-select: none;
}
#menuToggle input{
display: block;
width: 40px;
height: 32px;
position: absolute;
top: -7px;
left: -5px;
cursor: pointer;
opacity: 0;
z-index: 2;
-webkit-touch-callout: none;
}
#menuToggle span{
display: block;
width: 33px;
height: 4px;
margin-bottom: 5px;
position: relative;
background: #000000;
border-radius: 3px;
z-index: 1;
transform-origin: 4px 0px;
transition: transform 0.5s cubic-bezier(0.77,0.2,0.05,1.0),
background 0.5s cubic-bezier(0.77,0.2,0.05,1.0),
opacity 0.55s ease;
}
#menuToggle span:first-child{
transform-origin: 0% 0%;
}
#menuToggle span:nth-last-child(2){
transform-origin: 0% 100%;
}
#menuToggle input:checked ~ span{
opacity: 1;
transform: rotate(45deg) translate(-2px, -1px);
background: #000000;
}
#menuToggle input:checked ~ span:nth-last-child(3){
opacity: 0;
transform: rotate(0deg) scale(0.2, 0.2);
}
#menuToggle input:checked ~ span:nth-last-child(2){
opacity: 1;
transform: rotate(-45deg) translate(0, -1px);
}
#menu{
background-size:cover;
background-repeat:no-repeat;    
position: absolute;
width: 100vw;
height:100vh;
margin: -77px 0 0 -50px;
padding: 50px;
padding-top: 125px;
background-color: rgba(255,255,255,1);
list-style-type: none;
-webkit-font-smoothing: antialiased;
transform-origin: 0% 0%;
transform: translate(-100%, 0);
transition: transform 0.5s cubic-bezier(0.77,0.2,0.05,1.0);
}
#menu li{
padding: 10px 0;
font-size: 60px;
text-align: center;
}
#menuToggle input:checked ~ ul{
transform: scale(1.0, 1.0);
opacity: 1;
}

@media only screen and (max-width:480px) { 
#menuToggle input {
top: 2px;
left: -5px;
}
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="menuToggle">
  <input type="checkbox" />
  <span></span>
  <span></span>
  <span></span>

  <ul id="menu" class="navbar-collapse">
    <li><a href="#1">idi na 1</a></li>
    <li><a href="#2">idi na 2</a></li>
    <li><a href="#3">idi na 3</a></li>
  </ul>
</div>

注意:不要忘记将您的 js 代码放在 document.ready 中。

$(function() {
 $('#menu > li > a').on('click', function() {
      $("#menuToggle").find('input').trigger("click");
    });
});
