Solution to challenge

Hi everybody,

I have difficult about the work Dave assigned to us!

I've tried to make the exercise but it doesn't work. In particular, how can I solve the problem if there are two person with the same name?

This is my code. Can you help me? I'm really curious to have the solution. Thanks

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

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) { var reportFound = false; search = prompt('Search student records: type a name [Jody] (or type "quit" to end)'); if (search === null || search.toLowerCase() === 'quit') { break; } for (var i = 0; i < students.length; i += 1) { student = students[i]; if (student.name === search) { message = getStudentReport(student); print(message); reportFound = true; } } if ( !reportFound ) { message = "<p>There is no student with the name " + search.toUpperCase() + ".</p>"; print( message ); } } '''

Sorry, there were some mistakes...

This is the right code:

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

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) { var reportFound = false; search = prompt('Search student records: type a name [Jody] (or type "quit" to end)'); if (search === null || search.toLowerCase() === 'quit') { break; } for (var i = 0; i < students.length; i += 1) { student = students[i]; if (student.name === search) { message = getStudentReport(student); print(message); reportFound = true; } } if ( !reportFound ) { message = "<p>There is no student with the name " + search.toUpperCase() + ".</p>"; print( message ); } } '''

Please fork your Workspace or use JS Beautify for us to understand your solution better :)

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

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) {
    var reportFound = false;
    search = prompt(
        'Search student records: type a name [Jody] (or type "quit" to end)'
    );
    if (search === null || search.toLowerCase() ===
        'quit') {
        break;
    }
    for (var i = 0; i < students.length; i +=
        1) {
        student = students[i];
        if (student.name === search) {
            message = getStudentReport(
                student);
            print(message);
            reportFound = true;
        }
    }
    if (!reportFound) {
        message =
            "<p>There is no student with the name " +
            search.toUpperCase() +
            ".</p>";
        print(message);
    }
}
