手机上的响应菜单在滚动时消失了？

Question

我正在尝试建立一个响应网站，并且在移动菜单方面遇到一些困难。当我在移动设备上滚动浏览页面时，菜单消失了。

我试图使菜单粘在顶部，并且当用户想要关闭时，菜单只会消失。有没有一种方法可以保持菜单打开，直到单击链接或单击关闭菜单按钮？

您可以在这里看到它的实时运行：www.nhadatsonnghia.com

任何帮助将不胜感激！

非常感谢。

这是我的代码：

! function(n) {
    n.fn.menumaker = function(s) {
        var e = n(this),
            i = n.extend({
                title: "",
                format: "dropdown",
                sticky: !1
            }, s);
        return this.each(function() {
            return e.prepend('<div id="menu-button">' + i.title + "</div>"), n(this).find("#menu-button").on("click", function() {
                n(this).toggleClass("menu-opened");
                var s = n(this).next("ul");
                s.hasClass("open") ? s.hide().removeClass("open") : (s.show().addClass("open"), "dropdown" === i.format && s.find("ul").show())
            }), e.find("li ul").parent().addClass("has-sub"), multiTg = function() {
                e.find(".has-sub").prepend('<span class="submenu-button"></span>'), e.find(".submenu-button").on("click", function() {
                    n(this).toggleClass("submenu-opened"), n(this).siblings("ul").hasClass("open") ? n(this).siblings("ul").removeClass("open").hide() : n(this).siblings("ul").addClass("open").show()
                })
            }, "multitoggle" === i.format ? multiTg() : e.addClass("dropdown"), i.sticky === !0 && e.css("position", "fixed"), resizeFix = function() {
                n(window).width() > 768 && e.find("ul").show(), n(window).width() <= 768 && e.find("ul").hide().removeClass("open")
            }, resizeFix(), n(window).on("resize", resizeFix)
        })
    }
}(jQuery),
function(n) {
    n(document).ready(function() {
        n("#cssmenu").menumaker({
            title: "",
            format: "multitoggle"
        })
    })
}(jQuery);

[好吧，我明白了，我对您的建议只是编写一个附加类.show，该类应该在click事件中切换。当用户单击“ X”按钮时，应将其删除。在类'.show'中添加以下参数：

#menu-desktop .show {
    background: #ffbd2f;
    padding: 0 5px;
    display: block;
    position: fixed;
    top: 0;
    left: 0;
    height: 100%;
    width: 100%;
    z-index: 9999;
}

这将为您提供处理移动菜单的机会，用户可以一直看到它。

当然，如果您不想隐藏所有屏幕，则可以删除height属性或手动添加其他值。
