推荐答案

您无法强制执行JavaScript中的行为，需要在服务器端设置HTTP标头：

You can not force that behavior from JavaScript, the HTTP Headers need to be set on the server side:

Content-disposition=attachment; filename=some.file.name

解决问题的方法是让你的AJAX方法重定向用户到PDF的URL：

The way you can solve the problem is to let your AJAX method redirect the user to the URL of the PDF:

location.replace('path/to.pdf');

（必须为PDF设置上述HTTP标头）

(The above HTTP headers must be set for the PDF)
