js点击事件仅按钮可点，不显示点击后效果

 

 

本来点击这个应该出现菜单栏 如下图所示

但是现在不显示菜单栏 只有按钮可以按

这是我的js代码 （我是在vscode里写的）

$('.open-overlay').click(function() {
    var overlay_navigation = $('.overlay-navigation'),
      nav_item_1 = $('nav li:nth-of-type(1)'),
      nav_item_2 = $('nav li:nth-of-type(2)'),
      nav_item_3 = $('nav li:nth-of-type(3)'),
      nav_item_4 = $('nav li:nth-of-type(4)'),
      nav_item_5 = $('nav li:nth-of-type(5)'),
      top_bar = $('.bar-top'),
      middle_bar = $('.bar-middle'),
      bottom_bar = $('.bar-bottom');
  
    overlay_navigation.toggleClass('overlay-active');
    if (overlay_navigation.hasClass('overlay-active')) {
  
      top_bar.removeClass('animate-out-top-bar').addClass('animate-top-bar');
      middle_bar.removeClass('animate-out-middle-bar').addClass('animate-middle-bar');
      bottom_bar.removeClass('animate-out-bottom-bar').addClass('animate-bottom-bar');
      overlay_navigation.removeClass('overlay-slide-up').addClass('overlay-slide-down')
      nav_item_1.removeClass('slide-in-nav-item-reverse').addClass('slide-in-nav-item');
      nav_item_2.removeClass('slide-in-nav-item-delay-1-reverse').addClass('slide-in-nav-item-delay-1');
      nav_item_3.removeClass('slide-in-nav-item-delay-2-reverse').addClass('slide-in-nav-item-delay-2');
      nav_item_4.removeClass('slide-in-nav-item-delay-3-reverse').addClass('slide-in-nav-item-delay-3');
      nav_item_5.removeClass('slide-in-nav-item-delay-4-reverse').addClass('slide-in-nav-item-delay-4');
    } else {
      top_bar.removeClass('animate-top-bar').addClass('animate-out-top-bar');
      middle_bar.removeClass('animate-middle-bar').addClass('animate-out-middle-bar');
      bottom_bar.removeClass('animate-bottom-bar').addClass('animate-out-bottom-bar');
      overlay_navigation.removeClass('overlay-slide-down').addClass('overlay-slide-up')
      nav_item_1.removeClass('slide-in-nav-item').addClass('slide-in-nav-item-reverse');
      nav_item_2.removeClass('slide-in-nav-item-delay-1').addClass('slide-in-nav-item-delay-1-reverse');
      nav_item_3.removeClass('slide-in-nav-item-delay-2').addClass('slide-in-nav-item-delay-2-reverse');
      nav_item_4.removeClass('slide-in-nav-item-delay-3').addClass('slide-in-nav-item-delay-3-reverse');
      nav_item_5.removeClass('slide-in-nav-item-delay-4').addClass('slide-in-nav-item-delay-4-reverse');
    }
  })

这是html代码

    nav li a:hover:after {

    .open-overlay {
      right: 1rem;
    }
    nav li a:before {
      width: 25px;
    }
   
  }

     js代码部分我没改，这样已经可以出效果了。你拿去试一下，有用的话记得给个采纳。谢谢啦
