If i run the code in my browser it keeps poping up dialog even if i type Jody.

My code is below. Not sure what but if i run the code and type Jody then the dialog keeps appearing but if i close the dialog i see the student jody that i searched for.

var message = '';
var student;
var search;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}

function getStudentReport(student) {
  var report = '<h2>Student: ' + student.name + '</h2>';
  report += '<p>Track: ' + student.track + '</p>';
  report += '<p>Points: ' + student.points + '</p>';
  report += '<p>Achievements: ' + student.achievements + '</p>';
  return report;
}

while(true){
  search = prompt('Search student records: type a name [Jody] (or type "quit" to end)');
  if(search === null || search.toLowerCase() === 'quit') {
    break;
  }
  for (var i = 0; i < students.length; i += 1) {
    student = students[i];
    if(student.name === search) {
      message = getStudentReport(student);
      print(message);
    } else if(student.name !== search) {
      print(search + " deosn't exist!");
      break;
    }
  }
}

Hello Mark,

by the teacher note: Since this video was shot, the behavior of most browsers has changed, so you won't see the same thing as I demonstrate in the video. In the video, you'll see that my script is able to print out to the browser using document.write( ) while inside a loop.

Most browsers no longer do that: they wait until the loop finishes and then they print to the window. So, you'll see a blank page until you type quit in the prompt window — then you'll see all the output printed to the screen.
