Question

我爱Reddit。我使用的是新布局，而不是旧布局。有TamperMonkey的“附加”脚本，可让您执行隐藏帖子，更改颜色注释等操作，但是其中大多数仅适用于旧版式。然后是“ Reddit增强套件”，它做了一些修改，但不是我想要的。我修改了一个发现的脚本，但无法使其正常工作。我想要一个按钮，将所有链接添加到浏览器的历史记录，本质上将其标记为已访问，这使Reddit认为您已阅读了该帖子。

“按钮”短暂显示但随后消失，有人可以帮忙下面的TamperMonkey脚本吗？

这可能对您有用。随意编辑代码。

使用setTimeout将整个代码片段插入立即执行的函数中。
使用button获取最后一个querySelectorAll。
使用insertAdjacentElement插入元素。
请勿将微调框插入for循环内。在开始循环之前将其插入。
