I can't find the mistake

I copied the code exactly from the video. When it loads, the prompt box doesn't close even when the typed answer is correct. Quit works, though. 

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

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

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

}

while (true) {
  search = prompt('Search student records: Enter student name. Type "quit" to exit.');
  if ( search === null || search.toLowerCase() === 'quit' ) {
    break;
  } 
  for (var i = 0; i < students.length; i += 1) {
    student = students[i];
    if ( search === student.name ) {
    message = getStudentReport( student );
    print(message);
  }
 }
}

Hi Jamie,

while (true) will execute forever, unless there is a break statement.

Put a condition that can evaluate to true or false based on how you want to control the flow of the loop :)

Cheers,

Eric

The prompt box should close as soon as you enter any answer. Whether it is "correct" or not shouldn't matter. That's how it performed for me, but then I had only this part of the code.

Looking at the complete code might reveal more. You can share it easily by using the "snapshot" function in the workspace (the camera icon), and then posting the link it gives you her.e

i use var message empty string as a while loop "true or false" condition.

while(message === ''){
  search = prompt('type Students Name for Search or type "Quit" for exit from search');
  if(search === null || search.toLowerCase() === 'quit' ){
    break;
  }
for (var i = 0; i < students.length; i += 1){
  student = students[i];
  if(student.name === search){
    message = sTudentReport( student );
    print(message);
}
}
}
