需要突出显示并将文档从Google文档查看器复制到剪贴板 [英] Need to highlight and copy text from google doc viewer to clipboard

问题描述

我必须创建一个流程，向用户显示文档，用户可以突出显示文本并复制（并最终粘贴）文档某些部分的文本。

I have to create a process where a document is shown to the user and the user can highlight text and copy (and eventually paste) the text from some portions of the document.

我在iframe中使用谷歌文档查看器（因为我需要一个免费的通用文档查看器 - 虽然我对观众的其他想法持开放态度）。谷歌文档查看器做我需要的，但似乎我无法访问iframe的内部以获得突出显示的内容。

I am using google doc viewer in an iframe (since I need a universal doc viewer that's free - although I'm open to other ideas on viewers). Google doc viewer does what I need but it seems that I don't have access to the internals of the iframe to get the highlighted contents.

我看过很多与在javascript中触发副本（cntl-c）相关的链接，但在此过程中没有任何确定。

I've looked at many links related to triggering a copy (cntl-c) in javascript, but nothing firm in the process.

理想情况下，我想在iframe外部点击一个按钮，将按钮复制到剪贴板中，用户在google doc viewer内部进行选择。

Ideally I would like a button outside of the iframe to click on which would copy to the clipboard the selection a user made inside of the google doc viewer.

有关如何实现此目的的任何建议吗？

Any suggestion on how to achieve this?

推荐答案

利用 window.getSelection（）; 。
