$(function(){
  $( "#frmActiontest" ).submit(function( event ) {
     var url = $(this).attr('action');
          $.ajax({
          url: url,
          data: $("#frmActiontest").serialize(),
          type: $(this).attr('method')
        }).done(function(data) {
          //window.location.href="http://neuronguru.com/MedAdmin/tests/";
          window.location.reload();
          /*$('#result').html(data);
          $('#frmActiontest')[0].reset();*/
        });
      event.preventDefault();
  });
  $( ".test" ).on("click",function(event) {
        var url = $(this).data('url');
        var actionUrl = $(this).data('actionurl');
        console.log(actionUrl);
        $("#frmActiontest").attr('action',actionUrl);
        $.ajax({
          url: url,
          type: "GET",
          dataType: 'json'
        }).done(function(data) {
          data=data[0];
          $("#myModalTestLabel").html("Update Test");
          $("#simulationId").val(data.simulationId);
          $("#testTitle").val(data.testTitle);
          $("#description").val(data.description);
          //$("#contents").val(data.contents);
