Drupal 7 - Automatic file upload (hiding upload button)

So, sometimes you just want to hide "upload" button and instead upload all the files people drop to website instantly. This handy snipplet will help you. It will probably work for D8 as well.

Just place it in you .js file in theme folder.

function DropUpload() {
    $('input[type="file"]').change(function() {          
        $(this).parent().find('button.form-submit').mousedown();
    }); 
}
DropUpload();
jQuery(document).ajaxComplete(function(e, xhr, settings) {
    DropUpload();
});
