正文单击，如果打开，请关闭菜单

Question

$('#menuToggle, .menu-close').on('click', function(){
    $('#menuToggle').toggleClass('active');
    $('body').toggleClass('body-push-toleft');
    $('#theMenu').toggleClass('menu-open');
    $('#menuToggle').find($(".fa")).toggleClass('fa-rotate-180');
    $("body").toggleClass("active");
});

这是我的导航菜单幻灯片右侧的 JavaScript 代码。它工作正常，但我想在单击或关闭菜单后关闭此菜单，单击正文上的任意位置并切换按钮？

w3schools上有很多例子，你可以使用其中任何一个。但我个人喜欢的是：

function openNav() {
    document.getElementById("mySidenav").style.width = "250px";
    document.getElementById("main").style.marginLeft = "250px";
    document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
    document.getElementById("mySidenav").style.width = "0";
    document.getElementById("main").style.marginLeft= "0";
    document.body.style.backgroundColor = "white";
}

body {
    font-family: "Lato", sans-serif;
    transition: background-color .5s;
}
.sidenav {
    height: 100%;
    width: 0;
    position: fixed;
    z-index: 1;
    top: 0;
    left: 0;
    background-color: #111;
    overflow-x: hidden;
    transition: 0.5s;
    padding-top: 60px;
}
.sidenav a {
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 25px;
    color: #818181;
    display: block;
    transition: 0.3s
}
.sidenav a:hover, .offcanvas a:focus{
    color: #f1f1f1;
}
.sidenav .closebtn {
    position: absolute;
    top: 0;
    right: 25px;
    font-size: 36px;
    margin-left: 50px;
}
#main {
    transition: margin-left .5s;
    padding: 16px;
}
@media screen and (max-height: 450px) {
  .sidenav {padding-top: 15px;}
  .sidenav a {font-size: 18px;}
}

<div id="mySidenav" class="sidenav">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
  <a href="#">About</a>
  <a href="#">Services</a>
  <a href="#">Clients</a>
  <a href="#">Contact</a>
</div>
<div id="main">
  <h2>Sidenav Push Example</h2>
  <p>Click on the element below to open the side navigation menu, and push this content to the right. Notice that we add a black see-through background-color to body when the sidenav is opened.</p>
  <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>
</div>
