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 来做到这一点。在现代浏览器中，你可以简单地做<a href="somepathto.pdf" download="filename">

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 :
您还可以使用以下函数制作一个 PHP 页面来读取 PDF 并强制下载：
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)
（如果你想阻止用户删除下载属性，PHP 很有用，但可能太多了）
