推荐答案

由于这是一个很大的安全风险，所有关心安全的浏览器都不允许 JS 访问剪贴板.

Since this is a big security risk, all browsers that care about safety don't allow JS to access the clipboard.

主要原因是很多人将密码放入文本文件中，然后使用剪切和粘贴来登录.然后，破解者可以通过破解一个流行网站并安装一些 JS 向他们发送剪贴板内容，从剪贴板收集密码(可能还有其他私人信息，如您刚刚复制的 word 文档).

The main reason is that many people put their passwords into a text file and then use cut&paste to login. Crackers could then collect the password (and possibly other private information like the word document which you just copied) from the clipboard by cracking a popular site and installing some JS that sends them the content of the clipboard.

这就是我一直禁用闪光灯的原因.

Which is why I have flash disabled all the time.
