Not sure what i'm doing wrong!

Hi!

I've been trying to follow along with the challenge solutions, but can't seem to get anything to work even though i thought i had the same code as the instructor!

Can anyone take a look? Here's my code below. 

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);
    }
  }
}

Thanks for your help! R

Hi Rahim,

There are a few things. Firstly, there is nothing wrong with your code above. It does assume 2 things though, one is that you must have a container 'div' with id of 'output'. The second that you are checking in an array of 'students' for the name enterred.

<div id="output"></div>

Add this to the top of your Javascript:

var students = [];
students.push(new studentObject("John","Front End Development",3,820));
students.push(new studentObject("Theresa","Design",1,430));
students.push(new studentObject("Jules","PHP",4,140));
students.push(new studentObject("Kate","iOS",6,540));
students.push(new studentObject("Bob","Android",2,520));

function studentObject (name, track, achievements, points) {
    this.name = name;
    this.track = track;
    this.achievements = achievements;
    this.points = points;
}
