推荐答案

execCommand 在浏览器中并未完全标准化.事实上， execCommand('SaveAs', ...) 似乎只在 IE 上受支持.强制另存为的推荐方法是使用 content-disposition: 附件标头，如 http://www.jtricks.com/bits/content_disposition.html

execCommand is not completely standardized across browsers. Indeed, execCommand('SaveAs', ...) only seems to be supported on IE. The recommended way to force a save-as would be to use a content-disposition: attachment header, as described in http://www.jtricks.com/bits/content_disposition.html

由于这是 HTTP 标头的一部分，您可以在任何文件类型上使用它.如果您使用的是 apache，则可以使用 .htaccess 文件添加标头，如 此处.例如:

Since this is part of the HTTP header, you can use it on any file type. If you're using apache, you can add headers using the .htaccess file, as described here. For example:

<FilesMatch ".pdf$">
<IfModule mod_headers.c>
Header set Content-Disposition "attachment"
# for older browsers
Header set Content-Type "application/octet-stream"
</IfModule>
</FilesMatch>
