html - 如何在外部单击时关闭侧边栏菜单？

Question

我们如何通过单击外部来关闭侧边栏菜单？实际上我创建了一个侧边栏菜单，它通过切换按钮打开和关闭，但我也想通过点击外部来关闭它。我尝试了一些代码来关闭外部点击并且它有效但是当我点击打开任何子菜单时它也会关闭。任何关闭点击外部的解决方案。

a { text-decoration: none; }

div#overlay { display: none; }

  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%);
}

修改你的js代码如下，你也可以根据你的需要定制

(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)

这是你的工作代码王者替换你的旧代码
