How can we restrict a user from saving the page?

请提供一些提示，以禁用文件"->保存和查看源代码"选项

Please provide some tips to disable File->Save and View Source options

显然，它不能完成，并且可能不应该尝试.但是，关于这个问题的一个更有趣的变体是:如何使用户很难以可用的格式保存页面，以致于这样做不值得他们这样做?这个问题没有价值，但是说我们正在保护一个文章订阅站点，在该站点中，用户每年需要支付几百美元来继续访问文本.

Obviously it can't be done, and probably shouldn't be attempted. But possibly a more interesting variant on this question is how can we make is sufficiently hard for a user to save a page in a usable format such that it is not worth their while doing so? The question doesn't pose a value, but say we were protecting an article subscription site where the user is paying a few hundred dollars per annum for continued access to text.

推荐答案

由于页面已发送到客户端，因此总会有一种获取该信息的方法.试图阻止用户这样做只会使他们感到沮丧.

Since the page has been sent to the client, there will always be a way to get that information. Trying to stop a user from doing this will only frustrate them.

让用户无法保存文件的唯一方法是不将其发送给他们.

The only way to have a user not be able to save a file is to not send it to them.
