Solution to the last challenge from Student Record Search Challenge - it was about on how to display 2 objects

I wanted to post a solution on question from video - question was on how to print to browser 2 objects simultaneously in case those are hosting data for 2 students with the same names.

below is a code:

var message = ''; var studentA; var studentB; var searchStudent; var studentsArray = [];

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; }

for (var i = 0; i < students.length; i += 1) { studentsArray.push (students[i].name); }

while (true) { searchStudent = prompt('Type name of the student you are looking for in data base or type quit for exiting searchengine'); if ( searchStudent === null || searchStudent.toLowerCase() === 'quit' ) { break; }

if ( studentsArray.indexOf(searchStudent) === -1 ) { print('<h2>Sorry we dont have a student called <b>' + searchStudent + '</b> in our community.</h2>'); }

for (var i = 0; i < students.length; i += 1) { studentA = students[i]; if (searchStudent === studentA.name) {
for (var j = 0; j < students.length; j += 1) { studentB = students[j]; if ( studentA !== studentB && studentA.name === studentB.name) { message = getStudentReport(studentA); message += getStudentReport(studentB); print(message); }
} }
}

for (var i = 0; i < students.length; i += 1) { studentA = students[i]; if ( searchStudent === studentA.name ) { message = getStudentReport(studentA); print(message);
} }
}

Your first loop detects a duplicated name and displays both student records, but the second loop replaces that output with just the last student with that name.

Try removing the second loop (lines 83-89).
