调整窗口大小时切换菜单

Question

此菜单应放置在网站的中心，以适应浏览器窗口大小的调整。 现在它位于中间，动画就可以了。 但是，每当我尝试使菜单响应时，以便在我调整大小时将其保留在网站中间，动画将停止。 任何帮助请..

脚本

$(".menu").on("click", function () {
      $(".menu").addClass('permahover');

Answer 1

您所需要的只是在调整窗口大小时删除类。 请尝试以下操作：

$(window).resize(function(){ 
    $(".menu").removeClass("permahover")
});

我还想提及一下，您的菜单实际上不在屏幕右侧，并且用户实际上可以滚动到该位置。 将整个内容包装到一个盒子中，并隐藏其溢出内容以确保这不是问题。
