是否可以提取用户在pdf中选择的文本？ [英] Is it possible to extract the text selected by the user in a pdf?

问题描述

我找到了这个帖子，它解释了如何从中提取文本一个PDF在JavaScript中，但我想知道是否有可能提取只有用户选择的文本。

不能。

除非JavaScript呈现器（as-in，pdf.js）呈现PDF，否则浏览器的javascript无法访问PDF。

这是因为它是由浏览器插件呈现的，故意不允许javascript访问。

您的文章标有google-chrome-extension和google-chrome，但您的问题没有提及这些。您可能不会提出具体的问题。

I have found this post that explains how to extract the text from a pdf in javascript, but I would like to know if it's possible to extract only the text selected by the user.

解决方案

You can not.

The PDF, unless it's being rendered by a javascript renderer (as-in, pdf.js), can not be accessed at all by the browser's javascript.

This is because it's being rendered by a browser plugin that the javascript is intentionally not allowed to access.

Your post is tagged with "google-chrome-extension" and "google-chrome" but your question does not mention these. You might not be asking a specific enough question.
