$("#btnShow").on('click', function () {
  $("#ulList").empty();
  var fp = $("#fUpload");
  var lg = fp[0].files.length; // get length
  var items = fp[0].files;
  var fragment = "";

  if (lg > 0) {
    for (var i = 0; i < lg; i++) {
      var fileName = items[i].name; // get file name
      var fileSize = items[i].size; // get file size 
      var fileType = items[i].type; // get file type

      // append li to UL tag to display File info
      fragment += "<li>" + fileName + " (<b>" + fileSize + "</b> bytes) - Type :" + fileType + "</li>";
    }
