download HTML5 mp4 video using Javascript
HTML5 browsers now allow you to add the download
attribute to <a>
tags to achieve this in your DOM. You cannot do this in pure javascript.

If however, you have access to the server response, then in PHP you could do something like
<?php
header('Content-type: application/octet-stream');
readfile('myvideo.mp4');
You can use this:
$('submit').click(function() {
$('<a/>',{
"href":"The/video/src/path",
"download":"video.mp4",
id:"videoDownloadLink"
}).appendTo(document.body);
$('#videoDownloadLink').get(0).click().remove();
});
