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');

}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
只能帮你到将菜单显示出来，但是应该是有css3动画效果的，需要你自己找到原来的样式加上才行了。。增加style标签中的样式就能显示出菜单了，对你有帮助可以点击采纳支持下哦，谢谢~~

click事件没有注册对；alert(1)检查一下
首先确认你的回调函数走进来了没，在function第一句打印一下，然后就是希望你可以把html代码也发出来。这么看代码很难发现问题
nav_item_1 = $('nav li').eq(1) 这么写试试呢
最主要看你有没有报错
