9,760 PointsSolution 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);
}
}
}

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