我有一支笔，请尽量减少您的浏览器尺寸，因此它是移动尺寸，您应该看到汉堡包菜单。 这个想法是当你点击菜单时应该发生这种情况： - 汉堡图标变为＆＃39; x＆＃39;关闭图标 - 向下滑动菜单是使用班级＆＃39; isOPen＆＃39;它使用css关键帧（这是在笔上工作！）
当我点击＆＃39; x＆＃39;关闭图标应该发生：
我想要解决的问题：将关闭图标恢复为汉堡包菜单并向上滑动菜单。

使用.hasClass()检查元素是否具有类而不是.is()。
使用Javascript：
menu.on("click", function(e){
e.preventDefault();
if(menu.hasClass('active')){
closeMenu();
}else{
openMenu();
}
});
