将文件另存为-具有动态数据的对话框 [英] Save file as - dialog box with dynamic data

问题描述

我知道这个问题很普遍，但是它的细节困扰着我.

I know that this question is quite common, but its specifics are stumping me.

我有一个导出"按钮，我要提取生成的数据，创建一个CSV文件，然后弹出另存为"对话框，以将该文件保存在本地计算机上.

I have an "export" button which I want to take a load of data generated, create a CSV file, then pop up a Save File As dialog box, to save that file on their local machine.

此文件的名称也是动态的.

The name of this file is dynamic, also.

我知道如何制作CSV文件，但是如何在客户端弹出一个框让用户下载它呢?

I know how to make the CSV file, but how do I then pop up a box on the client side to let the user download it?

我在Struts中使用JSP

I am using JSP with Struts

推荐答案

您需要做的就是发送一个响应，其中包含生成的带有标题的csv:

All you need to do is to send a response containing your generated csv with a header:

Content-Disposition: attachment; filename=your_file.csv
