您可以使用AJAX来从Web应用程序下载一个生成的CSV文件？如果是的话没有任何人有任何种类的参考，我可以指向了？

Can you use AJAX to download a generated csv file from a web application? If so does anyone have any kind of reference that I could be pointed towards?

编辑：对不起，我应该提到，我使用Prototype的Ajax.Request的，我看着萤火虫的反应工具和生成CSV是响应，我只需要得到它弹出的保存文件的选项已经生成后，由Ajax.Request的

Sorry I should have mentioned I am using Prototype's Ajax.Request and I looked in firebug's response tool and the generated CSV is the response, I just need to get it to pop up with the save file option after has been generated by the Ajax.Request

推荐答案

这是Ajax请求的一个已知的限制，您将需要使用JS这样的：

This is a known limitation of Ajax requests, you will need to use JS like:

window.location='download-csv.rb';

而不是使用一个Ajax请求

。另一种方法是改变一个隐藏的iframe的位置，但是这有它自己的亲的/反对的。

Instead of using an Ajax request. Another way is to change the location of a hidden Iframe, but this has it's own pro's/con's.

您将永远不会得到一个Ajax请求来显示'文件保存'对话框，不管你发送的HTTP标头。

You will never get an Ajax request to display the 'file save' dialog, no matter what HTTP headers you send.
