回答by What have you tried
You shouldn't try to do this, let me tell you why. I'm assuming you want to disable ctrl+ cbecause you don't want the user to be able to copy content from your site, well have you thought about the fact that there are a dozen of other ways to copy your content?
你不应该尝试这样做，让我告诉你为什么。我假设您想禁用ctrl+c因为您不希望用户能够从您的站点复制内容，那么您是否考虑过有很多其他方法可以复制您的内容？
- Download html file and copy in their favorite text editor
- Inspect element and copy content from there
- Use mouse to right click -> copy
- 下载 html 文件并复制到他们最喜欢的文本编辑器中
- 检查元素并从那里复制内容
- 使用鼠标右键单击 -> 复制
And for my good friend @glenatron:
对于我的好朋友@glenatron：
- Network sniffer like Fiddler between the browser and the network card
- Screenshots, Taking a photograph of the monitor
- 浏览器和网卡之间类似Fiddler的网络嗅探器
- 屏幕截图，拍摄显示器照片
... The list goes on and on.
......这个名单不胜枚举。
Also, trying to stop users from normalfunctionality will only bother and annoy them; most likely causing them to leave your site and never return.
此外，试图阻止用户使用正常功能只会让他们感到烦恼和烦恼；最有可能导致他们离开您的网站，再也不会回来。
