Copied code exactly and it doesn't work..

So I cant complete a single challenge on my own. Now I copy everything exactly and it doesn't work. I really don't understand whats going on..

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

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 [Dave](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);
    }    
  } 
}

thanks

Tom, if you're having the same problem I did, also after not having the code print out. I type the code in exactly like how it was in the video, but it wouldn't print out the student records. So, I figured out the problem it was in my students.js file, the names in the name field had the first letter capitalized, I changed to lower case and after that it worked.

Thank you Gremyko, I was having the same problem and could not for the life of me figure it out!

The teacher's notes of the video say:

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.

So if the alert is what is not working, that is why.

Holy fuck, that god. I had the my data printing out, but spent fucking 30min-1hour trying to figure out why the hell it was only printing AFTER i hit QUIT (sorry for profanities but super frustrated).

You guys need to do an update on the video ASAP before people paying for this program waste 1 hour of their lives like I just did -_-

Hello, Tom,

Which part of this code does not work correctly ?
