Question

我有一个有大桌子的网站，它非常高，因此要进入水平滚动条，我必须滚动到页面底部。

反正是否有水平滚动条漂浮在窗口底部并始终可以访问而无需先滚动到网页底部？

Answer 2

有一个很好的jQuery插件floatingscroll可以解决这个问题。

示例：

$(document).ready(function () {
    $(".spacious-container").floatingScroll();
});

使用演示here

Answer 3

<强> R上。奥斯特霍尔特的回答非常美好。但是因为我是菜鸟，所以它耗尽了我的4个小时才能让它发挥作用。为了节省其他时间：你必须在div上添加以下样式：

.spacious-container {
    overflow: auto;
    width: 100%;
}

然后致电

$(document).ready(function () {
    $(".spacious-container").floatingScroll();
});

注意： attachScroll()是旧方法，将在以后的版本中删除。

可以找到插件的详细信息here (floating-scroll)

Answer 4

将table放入div。设置div＆＃39; height，并在其上设置overflow: auto。

可以有一个浮动水平滚动条？
