JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge Solution

Can't understand some parts in this video. Can someone who did it well help me please?

Here are some parts in this video that I need help. First, I included toLowerCase function in my code, but when I type the name 'sarah' in the prompt it won't work, unless I type 'Sarah', with the first letter being capital. Can someone tell me what's wrong? Second, does someone have the solution for the last challenge where Dave asked us to display the data for both person if they have the same name.

Thanks.

Here is my code:

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

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

function studentReport(student) {
  var report = '<h2>Student: ' + student.name + '</h2>';
    report += '<p>Track: ' + student.track + '</p>';
    report += '<p>Achievement: ' + student.achievement + '</p>';
    report += '<p>Point: ' + student.points + '</p>';
  return report;
}



while (true) {
  search = prompt("Enter a name in the search here. We'll display the person's info if we find it in our database.");

  if (search === null || search.toLowerCase() === 'quit') {
    break;
  }

    for (var i = 0; i < students.length; i++) {

      student = students[i];
      if (student.name === search) {
        message = studentReport(student);
        print(message);
      }
    }
}

My code is almost the same as Dave.

Hi Jason,

It looks like you only included the toLowerCase method for when the user types "quit".

Here's how I did the last project in this course:

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

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)');
  studentFound = false;
  if (search === null || search.toLowerCase() === 'quit') {
    break;
  }
  for (var i = 0; i < students.length; i += 1) {
    student = students[i];
    if (student.name.toLowerCase() === search.toLowerCase() ) {
      message += getStudentReport( student );
      studentFound = true;
    }
    if (i === students.length - 1 && studentFound !== true){
      message += '<p>Sorry, there is no student registered by the name of ' + search + '</p>';
    }
  }
  print(message);
}

try this, Jason.

if ( student.name.toLowerCase() === search.toLowerCase() ) {
