JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge Solution

One Solution for the extended Student Record Search Challange

Here is a possible solution to Dave's challenge. The way it works is that I created an empty array called "matchingSearchResults".

Then if the program finds a match it pushes the properties and values of the matching object into the array.

After this it checks whether the array is empty. If yes you get an alert, if not it prints out the data you requested.

Here is the student_report.js file

// Declaring the functions
var message = '';
var matchingSearchResults = [];

function print(message) {
    var outputDiv = document.getElementById('output');
    outputDiv.innerHTML = message;
}

// Starting the search loop
while (true) {
    var search = prompt("Type in the student's name you are looking for. If you want to stop, type in QUIT!")
    if (search === null || search.toUpperCase() === "QUIT") {
        break;
    }
// If we find a matching name the matching object's properties and values are pushed into the matchingSearchResults array
    for (var i = 0; i < students.length; i ++) {
        if (search === students[i].name) {
            matchingSearchResults.push(students[i]);
        }
    }
// If the matchingSearchResults array is empty we get an alert
    if (matchingSearchResults.length < 1){
        alert("We don't have any student named like that!")
    }
// Otherwise we print out the array's content
    for (var j = 0; j < matchingSearchResults.length; j ++) {
        message += '<h2>Student: ' + matchingSearchResults[j].name + '</h2>';
        message += '<p>Track: ' + matchingSearchResults[j].track + '</p>';
        message += '<p>Points: ' + matchingSearchResults[j].points + '</p>';
        message += '<p>Points: ' + matchingSearchResults[j].achievements + '</p>';
        print(message);
    }
// Resetting the array otherwise every time we would type a new name into the box it would print out the entire content of the array rather than working properly
    matchingSearchResults = [];
