使用window.print内容以pdf格式下载网页

问题描述：

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

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>

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

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

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 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.

我想有一个链接点击时，会自动开始下载网页的可打印版本。 p>

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 p>

 ＆lt; a href = \“whatever.htm \”onClick  = \“window.print（）;返回false \”＆gt;下载网页＆lt; / a＆gt; 
  code>  pre> 
 
 我想要那个内容，因为使用这种方式， 标题，侧边栏和页脚已删除。 我不想要CSS。 p> 
 
 
我没有使用它，因为这在某些浏览器中不起作用。 p> 
 
 
我不想 使用像tcpdf这样的pdf库，因为Moodle以动态的方式加载内容并将其发送到类似的库中。 p> 
 
 
我尝试使用像pdfcrowd.com这样的网站但这种网站 当您要转换为pdf的站点使用服务器端会话来识别用户时，不起作用。 p>

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

**There is easy ways to use jsPDF its very simple just you will use JSpdf Library **

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

function onClick() {
  var pdf = new jsPDF('p', 'pt', 'letter');
  pdf.canvas.height = 72 * 11;
  pdf.canvas.width = 72 * 8.5;

  pdf.fromHTML(document.body);

  pdf.save('test.pdf');
};

var element = document.getElementById("clickbind");
element.addEventListener("click", onClick);
