Question

对于此linkify plus脚本，我正在尝试使用href将GM_Setclipboard链接一键复制到剪贴板。

如果相关网页仅查找并“链接”一个文本字符串，则脚本可以正常工作。如果它链接两个字符串，则单击复制功能适用于两个链接，但只会复制最后一个字符串以进行“链接”。

我甚至不确定我想要做什么是可能的。找到了一些使用flash + jQuery + zeroClipboard的类似问题/解决方法。但不确定我是否可以将其实现为Greasemonkey脚本。

使用Anthony Lieuallen最新的脚本v2.0.2。 GM_setClipboard现在就像魅力一样。见下文：

// @namespace   http://arantius.com/misc/greasemonkey/
// @description Turn plain text URLs into links.    Supports http, https, ftp, email addresses.
// @grant GM_setClipboard
// ==/UserScript==

看看这是否有帮助。我现在正在打电话，所以不能探索太多。一旦我上系统，我会尝试。
