邪恶的PDF-等待AJAX​​请求完成 [英] Wicked PDF - Wait for AJAX request to finish

问题描述

我正在尝试使用WickedPDF生成PDF，并且我的所有静态HTML/CSS都正在加载.我在页面上有一些使用AJAX请求填充的元素，但是它们没有显示在PDF中.

I'm trying to generate a PDF using WickedPDF and all of my static HTML/CSS is loading. I have a few elements on the page that are populated using AJAX requests, but they are not showing up in the PDF.

我知道:redirect_delay可以作为参数传递，但是在等待我的AJAX调用完成的情况下这无济于事.由于我没有看到任何有关Wicked PDF和AJAX调用生成的页面的信息，所以我想问一下:

I know :redirect_delay can be passed as a parameter, but this does not help in the case of waiting for my AJAX calls to finish. Since I didn't see any mention of Wicked PDF and pages generated from AJAX calls, I figured I'd ask:

我要使用Wicked PDF(或其他项目)来做些什么吗?还是必须在生成PDF之前将所有内容传递给前端?

Is what I'm trying to do possible with Wicked PDF (or other projects), or do I have to pass everything to the front end before generating a PDF?

推荐答案

这应该有效:

render :pdf => 'out.pdf',
       :javascript_delay => 5000
