将溢出隐藏应用到绝对定位的容器

Question

我有一个 div，其中包含一些信息，例如图表。我们称它为 container。在 container 我还有另外两个 divs。一个 div 是带有日期的 header，另一个 div 是与这些日期对应的数据。我想固定 header/dates div 的位置。所以它会随着用户向下滚动。我遇到的问题是它删除了 overflow: hidden css 样式，因为它的位置。有没有办法仍然保留带有 position: fixed 或 position: absolute 样式的 div 的 overflow: hidden？

这是一个简单的 JSFiddle 示例。从 .titleSection-right 中删除 CSS 样式 position: fixed 以查看所需的截止点

Answer 1

要使 overflow:hidden on .titleSection-right 正常工作，您需要在此元素上设置一个固定的 width。在这种情况下，它的宽度需要分别等于 parents 宽度，.rightSide 具有百分比宽度。所以我在你的 JS

中添加了这段代码

var maxWidth = $(".rightSide").width()
$(".titleSection-right").width(maxWidth)

这样，.titleSection-right 将具有 .rightSide

的 width

看这里：jsfiddle

或下面的片段

$(function() {

    var maxWidth = $(".rightSide").width()
        $(".titleSection-right").width(maxWidth)
