如何关闭侧边菜单，单击外面

Question

我们如何通过单击外部关闭侧边栏菜单？实际上，我创建了一个侧栏菜单，它可以通过切换按钮打开并关闭，但我也想通过单击外部来关闭它。我尝试了一些代码以关闭外部单击，并且可以工作，但是当我单击以打开任何子菜单时，它也关闭。单击外部关闭的任何解决方案。

a { text-decoration: none; }
div#overlay { display: none; }
a#toggle {
  position: fixed;

  display: none;

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

编辑您的JS代码以下，您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，凭借旧代码
