Code doesnt work completely

Any ideas why the prompt keeps repeating the request for a name and does not give the student info? Code comes up clean in the console. txs.

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 [Pete] into the search, or enter "quit" to exit the program'); 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); }

}

The same thing also is happening for me. Is it something with the browser...I am using Chrome? My solution was working except it wasn't printing out the search result until I exited with quit.

Hi Immanuel,

You are checking if the students name is actually "search", and not if it's the variable 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 [Pete] into the search, or enter "quit" to exit the program'); 
  if (search === null || search.toLowerCase() === 'quit') break; 
} for (var i = 0; i < students.length; i += 1) { 
  student = students[i];

  if ( student.name === 'search') { // Look at this statement
    message = getStudentReport(student); 
    print(message); 
  }

}

------ EDIT -------

You are also not closing your loops and ifs properly. I should've caught that the first time around. Solution works here through workspaces. Though it doesn't print out the information in the background as in the video, and I can't see why.

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 [Pete] into the search, or enter "quit" to exit the program'); 
 if (search === null || search.toLowerCase() === 'quit') {break};

 for (var i = 0; i < students.length; i += 1) { 
  student = students[i];

    if ( student.name === search) { // Look at this statement
      message = getStudentReport(student); 
      print(message); 
    }


  } // Closing for loop
} // Closing while loop

Hey thanks. Unfortunately, after making the change, the prompt continues to act up. :(
