Answer 1

if(timeup)
{
  alert("welcome to time up.");
  var id = document.getElementById("test_id").value;
  var no = document.getElementById("noq").value;

  //use encodeURIComponent()
  var action = encodeURIComponent('result.php?id='+id+'&no='+no+'');

  //get the form
  var exercisenew = document.getElementById("exercisenew")
  exercisenew.action = action;

  alert("form"+exercisenew.action);
  exercisenew.submit();
  alert("form submitted.");
}
