制作下载链接DOMPDF生成的PDF同一页面上

问题描述：

我正在从数据库中的值动态生成HTML页面。用户必须隐藏的div和操作页面上的其他元素的选项。我要发送的页面，DOMPDF上的所有HTML和有它生成一个下载链接给我。

I'm making a dynamic html page generated with values from a database. The user has the option to "hide" divs and manipulate other elements on the page. I want to send all the HTML on the page to DOMPDF and have it generate a download link for me.

<a href="dl.php">Download</a>

在哪里dl.php将有这样的事情，其中的HTML被送到DOMPDF和产生的：

Where dl.php would have something like this where the html is sent to DOMPDF and generated:

$ DOMPDF =新DOMPDF（）; $ dompdf-＆GT; load_html（$ HTML）; $ dompdf-＆GT;渲染（）; $ dompdf-＆GT;流（myCV.pdf）;

$dompdf = new DOMPDF(); $dompdf->load_html($html); $dompdf->render(); $dompdf->stream("myCV.pdf");

然而，由于用户操作页面上的DOM，我想，我使用jQuery抢HTML摆脱这样的东西联系

However since the user is manipulating the DOM on the page and I want to get rid of stuff like links, I'm using jquery to grab the html

   $('a').wrap('<span style="display:none;"></span>');
   var fullhtml = $("#body").html();
   fullhtml = encodeURIComponent(fullhtml);

annnndd因为它是一个大的页面，我不能使用GET，必须使用POST发送的HTML。我将如何得到它，这样我可以做一个AJAX调用与HTML到dl.php，只是'包括'，这样它运行的页面？如果我从一个AJAX调用返回任何内容，PDF文件被转换成文本是一个烂摊子。

annnndd since it's a large page, I can't use GET, have to use POST to send the html. How would I get it so that I can just do a AJAX call with the html to dl.php and just 'include' the page so that it runs? If I return anything from a AJAX call, the pdf file gets converted into text which is a mess.

答

我不知道我理解你的问题正是，但据我了解，你正在做网页的HTML，隐藏所有的联系，然后提交POST请求里面整件事 dl.php ，对不对？因此， dl.php 会说这样的事情：

I'm not sure I understand your question exactly, but as far as I understand, you're taking the HTML of the page, hiding all the links, and then submitting the whole thing inside a POST request to dl.php, right? So dl.php would say something like this:

$html = urldecode($_POST['html']);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
//...

右？

您可以让用户通过点击一个链接，在这一点上，你有一个隐藏的输入与处理的HTML填充表单启动这个过程中（隐藏链接等）提交发生之前，即：

You could have the user initiate this process by clicking a link, at which point you populate a form with a hidden input with the processed HTML (links hidden, etc.) before the submission takes place, i.e.:

$('a#submit_link').click(function() {
  // wrap links, etc. here
  var html = $("body").html();
  $('#hidden_form_input').val($html);
  $('#hidden_form').submit();
});

这样的事情应该那么present您与生成的PDF用户。

Something like this should then present your user with the generated PDF.
