如何向 Lightbox 中的图像添加第二个水平滚动条？

Question

我正在尝试向 Lightbox 生成的弹出图像添加第二个水平滚动条。我知道滚动条并不是 Lightbox 的预期用途。 Lightbox 中的图像传统上受窗口大小的限制。但是，滚动条是客户想要的，现在，图像底部有一个滚动条，我想在图像顶部添加第二个滚动条。

在我的jsfiddle中https://jsfiddle.net/mrgfvwd1/1/弹出图像底部有一个滚动条（当然，我们忽略jsfiddle添加的水平和垂直滚动条）。

我想在图像上方添加第二个水平线，我正在遵循之前的答案表格顶部和底部的水平滚动条及其jsfiddlehttps://jsfiddle.net/TBnqw/1/

但是我无法弄清楚在 Lightbox 中使用哪个 div 或容器来定位，无论是使用将滚动条“回显”到顶部的 jQuery 函数（在上面问题的可接受答案中），还是纯 CSS 解决方案。我可以使用 jQuery 附加或前置将 div .wrapper1 添加到 Lightbox 的标记输出吗？

我正在小提琴中本地加载 Lightbox 脚本，以防需要修改。我知道这不是一个好主意，但最坏的情况下，我们可以。

Answer 1

可以添加

      <div id="upper-scroll" style="width:100%;height:10px;background-color:red;overflow-x:scroll;"><div id="inner-scroll" style="height:1px;"></div></div>

到图像上方的灯箱，然后添加这些卷轴：

$(function () {
  $("#upper-scroll").scroll(function () {
    $("#lightbox").scrollLeft($("#upper-scroll").scrollLeft())
  })
  $("#lightbox").scroll(function () {
    $("#upper-scroll").scrollLeft($("#lightbox").scrollLeft())
  })
})

您基本上为

scroll

创建一个

#upper-scroll

事件，以便将类似的

scroll

作为事件应用到

#lightbox

，反之亦然。最后，您需要确保您的卷轴大小相似，因此添加以下内容：

$("#inner-scroll").css("width", $(".lb-image").width());

到

showImage

。
