使用window.print内容以pdf格式下载网页 [英] Use window.print content to download a web page as pdf

问题描述

我希望有一个链接，点击时，会自动开始下载网页的可打印版本。

I would like to have a link that when is clicked, automatically starts the download of the printable version of the web page.

我正在使用Moodle。我希望它的内容完全相同如果我使用ctrl + p下载页面并保存为pdf或使用

I'm using Moodle. The content I want it's exactly the same If I download the page using ctrl + p and saving as pdf or using

<a href=\"whatever.htm\" onClick=\"window.print();return false\">Download web page</a>

我想要那个内容，因为使用这种方式，标题，侧边栏和页脚被删除了。我不想要CSS。

I want exactly that content because using this way, the header, sidebar and footer is removed. I don't want css.

我没有使用它，因为这在某些浏览器中不起作用。

I'm not using this because this doesn't work in some browsers.

我宁愿不使用像tcpdf这样的pdf库，因为Moodle以动态方式加载内容并将其发送到像这样的库中。

I'd rather not using pdf libraries like tcpdf because Moodle loads the content in a dynamic way and send this to a libraries like that is a mess.

I尝试使用像pdfcrowd.com这样的网站，但是当你想要转换为pdf的网站使用服务器端会话来识别用户时，这种网站不起作用。

I tried using sites like pdfcrowd.com but this kind of sites don't work when the site you want to convert to pdf uses a server-side session to identify the user.

推荐答案

我不相信有办法用 window.print（）来做到这一点。但是，有免费提供HTML到PDF转换器，您可以自动开始下载。这方面的一个例子是 jsPDF ，这是一个免费的库，用于使用Javascript将HTML转换为PDF

I don't believe that there is a way to do this with window.print(). However, there are HTML to PDF converters available for free, and you could automatically start a download with that. An example of this would be jsPDF, a free library for converting HTML to a PDF with Javascript
