如何在红宝石中使用pdf查看器 [英] How to have pdf viewer in ruby

问题描述

我怎样才能将PDF阅读器嵌入到ruby中？

How can I embeded pdf viewer in ruby on rail?

现在我试过
< embed src =MyPdfDocument。 pdfwidth =500height =375>
但它不起作用。
$ b

Now I tried <embed src="MyPdfDocument.pdf" width="500" height="375"> but it doesn't work. I used firebug and see the error like this

[Exception ...]组件返回的失败代码：0x80004005（NS_ERROR_FAILURE）[nsIStreamListener.onStopRequest ]nsresult：0x80004005（NS_ERROR_FAILURE）location：JS frame :: file：///home/bengasi/.mozilla/firefox/cmb1mbzu.default/extensions/[e-mail]/components/firebug-channel -listener.js :: anonymous :: line 167data：no]
[Break on this error] this.listener.onStopRequest（request，requestContext，statusCode）; \\\

推荐答案

如果您试图将PDF作为图像显示，并包含HTML内容，那么浏览器不会这样做，而您的问题在于浏览器，而不是Ruby on Rails。您可以链接到PDF，并将其全部显示出来，但不能将其嵌入到其他文档中。

If you are trying to display a PDF as an image, surrounded by HTML content... then a browser won't do that, and your problem is with the browser, not Ruby on Rails. You can link to a PDF, and display it whole, but you cannot embed it in another document.

您可以模拟效果（可能在某些浏览器中） iFrame，但这是一个HTML问题，而不是rails问题......并且您可能会花费大量时间使其在所有浏览器中都可用。

You could simulate the effect (maybe, in some browsers) with an iFrame, but that is a HTML question, not a rails question... and you would possibly spend a lot of time making it work in all browsers.
