You don't need javascript to do this. In a modern browser you can simply do <a href="somepathto.pdf" download="filename">

你不需要javascript来实现这一点。在现代浏览器中，只需执行

You can use the HTML5 attribute download :

您可以使用HTML5属性下载:

<a href="link" download="filename"/>

You can also make a PHP page that will read the PDF and force the download, by using these functions :

你也可以制作一个PHP网页，阅读PDF并强制下载，使用以下功能:

header('Content-Type: application/pdf');
header('Content-disposition: attachment; filename=filename.pdf');
exit(readfile(yourPDF));

(PHP is useful if you want to prevent the users to delete the download attribute, but it may be too much)

(如果您想防止用户删除下载属性，PHP是有用的，但是它可能太多了)

Use the download attribute:

<a download="file.pdf">Link</a>
