使用javascript / ajax / jquery强制下载pdf链接 [英] Force download a pdf link using javascript/ajax/jquery

问题描述

假设我们有一个pdf链接 http://manuals.info.apple.com /en/iphone_user_guide.pdf （仅举例来说，让你知道我的服务器上没有该文件，我只有链接）...现在我必须在我的网站上提供一个下载按钮文件。

suppose we have a pdf link "http://manuals.info.apple.com/en/iphone_user_guide.pdf"(just for example and to let u know that file is not on my server, i only have the link)...now i have to provide a button on my site that will download the file.

我尝试了各种各样的东西，比如window.open，href等方法但是它打开了其他窗口上的链接。我知道这是因为现在所有的浏览器都带有一个adobe插件，可以在另一个窗口打开它，但仍然没有任何方式我给用户提供下载选项，而不是打开它，通过客户端脚本..

i have tried various things like window.open, href etc. methods but it open the link on other window. i know thats because now all browser comes with a adobe plugin which opens it in another window, but still isnt there any way i give the user the option of download rather than opening it, through client side scripting ..

plz help ..
