浏览器使用JavaScript下载文件提示 [英] Browser download file prompt using JavaScript

问题描述

我想知道是否有任何方法可以使用JavaScript实现浏览器的下载文件提示。

I was wondering if there was any method to implement browser's download file prompt using JavaScript.

我的理由 - 用户将上传文件到本地文件服务器，无法从网络服务器访问。换句话说，两者都将在不同的领域！

My reason - well users will be uploading files to a local fileserver which cannot be accessed from the webserver. In other words, both will be on different domains!

例如，假设网站托管在 www.xyz.com 上，但文件将驻留在本地文件服务器上地址如 \\10.10.10.01\Files\file.txt 。如何使用ActiveX和VBscript上传/传输文件到本地文件服务器！ （不要问： - ）

For example, let’s say websites hosted on www.xyz.com, but files would reside on local file server with address like \\10.10.10.01\Files\file.txt. How am I uploading/transferring file to local fileserver... using ActiveX and VBscript! (don’t ask :-)

所以我在我的数据库中存储本地文件路径并将数据绑定到网格。当用户单击该链接时，该文件将在窗口中打开（使用JavaScript）。

So I am storing local file path in my database and binding that data to a grid. When the user clicks on that link, the file opens in a window (using JavaScript).

问题是浏览器窗口中打开的某些文件类型，如text，jpg，pdf等。如何使用客户端脚本实现 content-type 或 content-disposition ？这甚至可能吗？

Problem is certain file types like text, jpg, pdf, etc. open inside browser window. How would I be able to implement content-type or content-disposition using client side scripting? Is that even possible?

编辑：
本地文件服务器有一个窗口的共享文件夹，文件保存在该文件夹中。

the local file server has a window's shared folder on which the files are saved.

推荐答案

content-disposition：attachment几乎是强制执行此操作的唯一方法，必须在响应标头中设置。

"content-disposition: attachment" is pretty much the only way to force that, and this MUST be set in the response header.
