// var adId = window.setInterval(function () {
//   var win = window.parent || window;
//   var ele = win.document.querySelector('#exampleTop') || win.document.getElementById('exampleTop');
//   if (ele) {
//     ele.setAttribute('style', 'display:none;');

function GetDetails(event) {
  var text = document.getElementById("myInput");
  if ('detail' in event) {
