Did you try using using a callback function as mentioned above?

Call back is working.

Abinay, Thanks a lot.

If I try to alert countrycode outside while loop, its pop up wrong value.

function onChange(control, oldValue, newValue, isLoading) {

  if (isLoading || newValue == '') {

  return;

  }

  var gp = new GlideRecord('core_country');

  gp.addQuery('name', newValue);

  gp.query(callBack);

  function callBack(gp){

  while(gp.next()){

  countrycode = gp.iso3166_3;

  }

  }

alert(countrycode);

}

You need to put alert inside the callback function. Otherwise it will not work. Please mark my response as correct.

Abinay,

I have to call one more table to fetch the data and the alert (test1) is not working . Please help me?

function onChange(control, oldValue, newValue, isLoading) {

  if (isLoading || newValue == '') {

  return;

  }

  var gp = new GlideRecord('core_country');

  gp.addQuery('name', newValue);

  gp.query(callBack);

  function callBack(gp){

  while(gp.next()){

  countrycode = gp.iso3166_3;

  // get locations using country from the u_citrix_office_locations name

  var gp1 = new GlideRecord('u_citrix_office_locations');

  gp1.addQuery('u_country_code', countrycode);

  gp1.query();

  while(gp1.next()){

  alert('test1');

  var location = gp1.u_address_1;

  location += " , "+gp1.u_address_2;

  location += " , "+gp1.u_building_name;

  g_form.addOption('vs_location', gp1.u_address_1, location);

  }

  }

  }
