一个人怎么可以检测复制在浏览器中的链接？ [英] How can one detect copying a link in a browser?

问题描述

昨天，我曾与一名出租车司机，并在提的是，我是一个程序员，他告诉我说，几天前，他曾经历了以下几个聊天：在试图将URL从他的浏览器的地址栏复制，一个消息框出现像的请不要复制此链接，而注册的

Yesterday I had a chat with a taxi driver and upon mentioning that I am a programmer, he told me that a couple of days earlier he had experienced the following: upon trying to copy the URL from the address bar of his browser, a messagebox appeared with a message like "Please don't copy this link, rather register".

我不是一个web开发人员，所以这可能是一个蹩脚的问题:-)但我不知道如何这样的事情是完成的？什么技术或语言给人一种这个水平的控制权事件在浏览器中？

I am not a web developer, so this might be a lame question :-) but I wonder how such a thing is accomplished? What technology or language gives one this level of control over the events within the browser?

该网站是某种电影下载服务的，据我的理解。我没有问他用什么浏览器，但他的平台是WinXP的所以大部分可能是IE浏览器。因为我没有实现此功能的技术的想法，我不能添加任何技术特定的标签，但如果你知道一个适当的，随意添加它。

The site was some sort of a movie downloading service, as far as I understood. I failed to ask him what browser he used, but his platform was WinXP so most probably it was IE. Since I have no idea of the technology implementing this feature, I can't add any technology specific tags, but if you know an appropriate one, feel free to add it.

在阅读的答案，最似乎收敛于认为

Upon reading the answers, most seem to converge on the opinion that

• 在浏览器页面上是相当容易实现，但


• 地址栏上没有，如果有可能的话。

我特意问回，以确保他的意思，他被复制从地址栏中的网址，他证实。尽管如此，它仍可能是两边的误解。我还没有看到的情况下发生的，从而为我听到它，我只能重复其描述。

I specifically asked back to make sure that he meant he was copying the URL from the address bar, and he confirmed that. Nevertheless, it might still be a misunderstanding on either side. I haven't seen the event happening, so I can only repeat its description as I heard it.

推荐答案

这曾经是可能的IE7和旧版本的Flash 10。

This used to be possible with IE7 and older versions of Flash 10.

在IE7（8我认为），你可以简单的：

In IE7 (and 8 I think), you can simply:

var vulnerability = window.clipboardData.getData("Text");

这是一个漏洞，并在IE9是默认不允许的。在Firefox挂钩到剪贴板接口也默认不允许的。在Safari /铬这不是在 onPaste 处理要么允许，除非明确。

This is a vulnerability, and in IE9 is disallowed by default. In Firefox hooking into the Clipboard interface is also disallowed by default. In Safari/Chrome this not allowed either, EXCEPT explicitly in onPaste handlers.

在Flash中，你可以简单地做 Clipboard.getData（）前几个月前。剪贴板现在已经在Flash中只写访问（但仍保留它在空气全部功能）。

In Flash, you could simply do Clipboard.getData() prior to several months ago. The Clipboard now has write-only access in Flash (but still retains it's full capability in Air).

在IE浏览器，你可以看到琐碎会做的。只需拨打 window.clipboardData.getData（文本）每隔几秒钟。使用Flash，它不会一直更难。只需简单勾一个Javascript功能到您的Flash视频和环路视频。

In IE, you can see how trivial this would be to do. Simply call window.clipboardData.getData("Text") every couple of seconds. With Flash, it wouldn't have been much harder. Simply hook a Javascript function into your Flash video and loop the video.

在上述类型特设的方式访问剪贴板是$ P $上的所有主流浏览器psently不可能的。

Accessing the clipboard in the aforementioned type of ad hoc manner is presently impossible on all major browsers.
