Question

如何通过单击外部关闭侧边栏菜单？实际上，我创建了一个侧边栏菜单，并通过切换按钮打开和关闭它，但是我也想通过单击外部将其关闭。我尝试在外部单击时关闭一些代码，它可以正常工作，但是当我单击以打开任何子菜单时，它也会关闭。在外部点击即可关闭的任何解决方案。



a { text-decoration: none; }

div#overlay { display: none; }

a#toggle {
  position: fixed;
  top: 50px;
  left: 1px;
  width: 40px;
  height: 40px;
  background-color: rgba(0, 0, 0, 0.4);
  text-align: center;
  color: white;
  display: none;
}

a#toggle i {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

main#content { padding: 10px; }

#menu {
  text-align: center;
  transition: all ease-out 0.3s;
}

#menu a { color: white; }

#menu ul {
  margin: 0;

  display: inline-block;

编辑您的js代码以遵循，也可以根据需要自定义

(function($){
  var ico = $('<i class="fa fa-caret-right"></i>');
  $('nav#menu li:has(ul) > a').append(ico);

  $('nav#menu li:has(ul)').on('click',function(){
    console.log('1');
    $(this).toggleClass('open');
  });

  $('a#toggle').on('click',function(e){
    console.log('2');
    $('html').toggleClass('open-menu');
    return false;
  });

  $('body,html').on('click',function(){
    console.log('3');
  $('html').toggleClass('open-menu');
});


  $('div#overlay').on('click',function(){
    console.log('5');
    $('html').removeClass('open-menu');
  })

})(jQuery)

这是您的工作代码被旧代码所取代
