javascript - 即使在外部或网页上的任何地方单击也隐藏菜单

Question

这是我的菜单栏代码。它工作正常。但是，我想实现目前的一件事，当我在菜单栏外单击时，它不会隐藏或关闭。即使在菜单栏处于事件状态时单击网页上的任意位置，我也想隐藏菜单栏。

function openNav() {
    document.getElementById("mySidenav").style.width = "50%";
}
function closeNav() {
    document.getElementById("mySidenav").style.width = "0";
}
(function ($) {
    // Instantiate MixItUp:
    // $('Container').mixItUp();
    // Add smooth scrolling to all links in navbar + footer link
    $(".sidenav a").on('click', function(event) {
        event.preventDefault();
        var datanew= this.href;
        var str2 = '.html';
        if(datanew.indexOf(str2) != -1){
            window.location.href = datanew;
        }else{
            var hash = this.hash;
            $('html, body').animate({scrollTop: $(hash).offset().top}, 
            900, function(){
                alert(window.location);
                window.location.hash = hash;
            });
        }
    });
})(jQuery);

.sidenav {
    height: 100%;
    width: 0;
    position: absolute;
    z-index: 1;
    top: 0;
    right: 0;
    background-color: #ef4f50;
    overflow-x: hidden;
    padding-top: 60px;
    transition: 0.5s;
    /*max-height: 551px;*/
}
.sidenav a {
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 25px;
    color: #ffffff;
    display: block;
    transition: 0.3s
}
.sidenav a:hover, .offcanvas a:focus{
    color: #f1f1f1;
}
.closebtn {
    position: absolute;
    top: 0;
    right: 25px;
    font-size: 36px !important;
    margin-left: 50px;
}
.menu-icon
{
    color: #114576;
    font-size: 30px;
    margin-top: 40px;
    margin-left: 40px;
    cursor: pointer;
}
.control {
    margin-top: 15px;
    margin-right: 40px;
}

.menu{
    min-height: 100px;
}

Answer 1

尝试使用类似的东西

$(window).click(function(event) {
  if ($(event.target).closest('div#mySidenav').length === 0 && $(event.target).closest('.menu-icon').length === 0) {
    closeNav()
  }
})

这将检查您是否单击“openNav”或菜单中的任何位置

function openNav() {
  document.getElementById("mySidenav").style.width = "50%";
}

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
}
(function($) {
  // Instantiate MixItUp:
  // $('Container').mixItUp();
  // Add smooth scrolling to all links in navbar + footer link
  $(".sidenav a").on('click', function(event) {
    event.preventDefault();
    var datanew = this.href;
    var str2 = '.html';
    if (datanew.indexOf(str2) != -1) {
      window.location.href = datanew;
    } else {
      var hash = this.hash;
      $('html, body').animate({
          scrollTop: $(hash).offset().top
        },
        900,
        function() {
          alert(window.location);
          window.location.hash = hash;
        });
    }
  });
})(jQuery);

$(window).click(function(event) {
  if ($(event.target).closest('div#mySidenav').length === 0 && $(event.target).closest('.menu-icon').length === 0) {
    closeNav()
  }
})

.sidenav {
  height: 100%;
  width: 0;
  position: absolute;
  z-index: 1;
  top: 0;
  right: 0;
  background-color: #ef4f50;
  overflow-x: hidden;
  padding-top: 60px;
  transition: 0.5s;
  /*max-height: 551px;*/
}

.sidenav a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #ffffff;
  display: block;
  transition: 0.3s
}

.sidenav a:hover,
.offcanvas a:focus {
  color: #f1f1f1;
}

.closebtn {
  position: absolute;
  top: 0;
  right: 25px;
  font-size: 36px !important;
  margin-left: 50px;
}

.menu-icon {
  color: #114576;
  font-size: 30px;
  margin-top: 40px;
  margin-left: 40px;
  cursor: pointer;
}

.control {
  margin-top: 15px;
  margin-right: 40px;
}

.menu {
  min-height: 100px;
}
