5,712 PointsCan't figure out why do I get a repeated "Sorry, we don't find xxx in the list". Thanks for help :-)
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) {
search = prompt("Search student records: type a name[Jody](or type βquitβ to end)");
if (search === null || search.toLowerCase() === 'quit') {
break;
}
else{
print("Sorry, we don't find " + search + " in the list.");
}
for (var i = 0; i < students.length; i += 1) {
student = students[i];
if(search === student.name) {
message = getStudentReport( student );
print(message);
}
}
}

if (search === null || search.toLowerCase() === 'quit') {
break;
}
else {
print("Sorry, we don't find " + search + " in the list.");
}
An "if...else
" always does one of two things. As you have constructed it, if the input is empty or the word "quit", you break out of the loop.
In all other cases ("else
"), you print the "Sorry..." message.
You probably want to restructure the code so the loop that checks the input against student names occurs first, and the "Sorry..." message is only printed when nothing is found.

5,712 PointsAh... I see, that's why even I have Jody in the student list it still gets printed out. Thanks a lot for the answer :-)
