如何让superfish下拉菜单响应?

标签: javascript jquery html css responsive-design

我正在使用带有skelton框架的superfish下拉菜单。我希望它也适用于手机。默认情况下,它会显示下拉项,但会将鼠标悬停在其下方的项目上。我想以某种方式让它在它下方推送父项。有解决方案吗

我能够将Superfish的相同HTML转换为响应式抽屉菜单。 JS非常简单,整个过程基本上都是使用CSS完成的。看看它,让我知道你们的想法!

<强>更新 请参阅Ryan Brackett的答案

下拉菜单在移动设备上无效。我建议在移动设备上隐藏superfish菜单并用其他东西替换它。

移动导航模式

对于寻找解决方案的其他人,请确保您使用的是最新的jQuery。我有一些较旧的网站,我发现使用更新版本的jQuery使Superfish菜单适用于移动设备。

正如Ed指出的那样,为响应式菜单解决所有不同的superfish / css问题似乎存在问题。

在查看了这里和其他地方的选项之后,我发现了一个Pure CSS响应菜单,它比superfish更快更容易修改,并且没有jquery或javascript的开销。它还有二级菜单。

我使用screenfly检查the demo以检查响应性和移动布局,然后再使用它。与codepen演示页面不同,CSSscript.com版本(上面的链接)为移动设备提供了水平响应式布局。

Pure Responsive CSS menu

mobile view from screenfly,  320px wide

代码位于单个HTML文件中,您可以轻松地将其拆分为链接的CSS文件,只有2个媒体查询可以管理响应式更改,即使只有最少的更改。可以删除“+”符号而不会出现问题。

只有一个微小缺点:第一个链接下载HTML底部有一个javascript,添加了明显的谷歌分析跟踪功能,可以轻松删除,而不是代码集。

这就是我使用的:

    isMobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent);

$(".menu a").click(function(event){
        if($(this).parents("ul").length == 1 && !$(this).hasClass("lastClick") && isMobile)
            event.preventDefault();     

        $(".menu a").removeClass("lastClick");
        $(this).addClass("lastClick");
    });

将“.menu a”替换为您的导航链接,此片段将在第二次点击后将用户导航到点击的网站,第一次点击只会向他显示子页面。

转发:只需更改您的CSS:

.xpopdrop > ul {
        display: block!important;
}

你会没事的。
