You can use Ajaxfileupload.js to upload file:

$('input[type="file"]').ajaxfileupload({
          'action': 'save_photo.php',
          'params': {
            'extra': 'info'
          },
          'onComplete': function(response) {

           console.log('custom handler for file:');
           alert(JSON.stringify(response));

          },
          'onStart': function() {               

          },
          'onCancel': function() {
            console.log('no file selected');
          }
    });

save_photo.php :
