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

Sharing code that prints details for multiple students with the same name

var message = '';
var student;
var answer;

/*
  this is the crux of my modifications, to store the student details in an array whenever the name
  (from the prompt) is encountered
  So, if I enter "Dave" at the prompt, and there are two students named Dave, the details
 for each Dave will be pushed (per the array method) onto the message array

 Note:  this code doesn't account for names not found in the students array
*/

var messageArray = [];

// changed message to messageArray as the incoming argument
function print(messageArray) {
   var outputDiv = document.getElementById('output');
   outputDiv.innerHTML = messageArray;
}


function searchForStudent(answer)  {
    for (var i = 0; i < students.length; i += 1)  {
       student = students[i];
       if (student.name === answer)  {
           message += '<h2>Student: ' + student.name + '</h2>';
           message += '<p>Track: ' + student.track + '</p>';
           message += '<p>Points: ' + student.points + '</p>';
           message += '<p>Achievements: ' + student.achievements + '</p>';
      /*
          Now I populate the messageArray with details of the student when the name matches
          but continue because there may be more students with the same name
      */

         messageArray.push(message);

      /*
         It is crucial to now reset the message variable (i.e,  details for a particular student)
         after pushing the details for a specific student into the array.

         Otherwise, the 'message' keeps growing, and each time a new student with the same name
         is found, those new details will populate the array as expected, BUT so will the details for
         students with the same name that have ALREADY been pushed to the array
     */ 

      message = '';
     } 
   }
   return messageArray;  
}

answer = prompt("Enter name of student");

while (answer !== "quit") {
     messageArray = searchForStudent(answer);
     print(messageArray);
    answer = prompt("Enter name of student");

When you format your code, if you add "js" after the 3 backticks on the top line you'll get nice syntax coloring.
