add a download with javascript on a website code example

Example 1: html download link

<a href="path/to/file.ext" download rel="noopener noreferrer" target="_blank">
   Download File
</a>

<!-- Please keep in mind that the dowload attribute is not supported by IE11. This why we need a target="_blank" fallback -->

Example 2: javascript download file

$('a#someID').attr({target: '_blank', 
                    href  : 'http://localhost/directory/file.pdf'});
