1. 当将时间轴手柄拖到末尾时，页面会跳转到页面底部。如果您的视口较短，这意味着您可能会完全跳过最后一篇帖子，直接跳转到推荐主题或页脚。

2. 相比之下，点击最后一篇帖子的日期时，您会被带到最后一篇帖子的顶部（我认为这样是合理的）

最近已针对移动设备对此进行了调整（[https://meta.discourse.org/t/jump-to-last-post-does-not-jump-to-correct-position-and-does-not-hide-jump-tool-after-scrolling/130600），但该问题在桌面端仍然存在。](https://meta.discourse.org/t/jump-to-last-post-does-not-jump-to-correct-position-and-does-not-hide-jump-tool-after-scrolling/130600%EF%BC%89%EF%BC%8C%E4%BD%86%E8%AF%A5%E9%97%AE%E9%A2%98%E5%9C%A8%E6%A1%8C%E9%9D%A2%E7%AB%AF%E4%BB%8D%E7%84%B6%E5%AD%98%E5%9C%A8%E3%80%82)

我支持这一更改，它能简化操作并保持一致性。

@martin 你能将这个更改应用到移动端和桌面端吗？（请务必在包含一篇非常非常非常长的帖子的主题上进行测试）

在此期间，您只需 **点击** 滑块底部，即可跳转到最后一篇帖子。手动将其向下拖动确实会带您到达页面底部……即最后一篇帖子之后。

从另一个话题来看，似乎并不清楚当初为何要实现这个跳转到末尾的功能。那么，我是否应该直接假设它并不需要，并移除 @pmusaraj 的变通方案以及 @daniel 的原始功能？

主要原因在于，如果你有一个巨大的帖子，即使你拖动滚动条到底部，仍然会卡在帖子的顶部，这非常令人沮丧。

啊，谢谢提供额外的上下文。所以在某些情况下确实还需要它。我会把这一点考虑进去 👍

我在此处为此问题添加了一个修复方案。

On my laptop my window height for Chrome is ~811 so any post taller than that will make the slider jump to the end of the page. I am not sure how to make this rule more dynamic without adding arbitrary heights to the window height in the comparison or doing ranges e.g. if your window height is 800-1200 the post must be \> 1400 height to jump to end of the page etc.

请查看我的拉取请求说明。我认为它运行良好，但可能仍有改进空间，以使限制不那么严格。

@awesomerobot 能否确认现在是否运行得更好/符合您的预期？🙂
