5,499 PointsHow can I stop this from printing 'Student Not Found' for each iteration of [i] where student.name != search?
I think I understand why the if...else statements in the for loop are causing the problem, but nothing I've tried seems to fix it. Does anyone have any suggestions?
I really just want it to print "Student Not Found" once if the name isn't in the students.js file.
var message = '';
var student;
var search;
function print(message) {
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.");
document.getElementById('output').innerHTML = "";
if (search === null || search.toLowerCase() === 'quit') { break;}
for (var i=0; i<students.length; i++) {
student = students[i];
if (student.name.toLowerCase() === search.toLowerCase()) {
message = getStudentReport(student);
print(message);
} else {
print('Student Not Found');
}
}
}

You can set a boolean in the loop if you find anything, and test it to see if the message should be used at all:
var notfound = true; // assume none will be found
for (var i=0; i<students.length; i++) {
student = students[i];
if (student.name.toLowerCase() === search.toLowerCase()) {
message = getStudentReport(student);
print(message);
notfound = false; // remember we found at least one
}
}
if (notfound) {
print('Student Not Found');
}

231,272 PointsThe "link to source" was a good idea, but...
You can't share a direct URL to your workspace, it's temporary and only exists while you are using it.
But you can use the snapshot function in the workspace and provide the link to that.
