Optional solution to Student Search Challenge, with additional changes to input.

Here is my solution to the challenge. It uses a text box rather than the window prompt. Let me know what you think.

//did not write this print function(owned by Dave McFarland - Treehouse)
function print(message) { 
  var outputDiv = document.getElementById('records');
  outputDiv.innerHTML = message;
}

var students = [
    { name: 'Chris', track: 'Full-stack developer', achievements: 50, points: 16280 },
    { name: 'Dave', track: 'Engineer', achievements: 75, points: 18722 },
    { name: 'Danny', track: 'Software QA', achievements: 150, points: 42085 },
    { name: 'Chris', track: 'Artist', achievements: 40, points: 13670 },
    { name: 'Bob', track: 'Director of photography', achievements: 110, points: 27345 },
    { name: 'Chris', track: 'Unity Developer', achievements: 130, points: 28956 },
    { name: 'Dave', track: 'Machine Learning', achievements: 77, points: 20722 },
];

var button = document.querySelector('#submit');
button.addEventListener('click', function() {
    var input = document.getElementById('txtBox').value;
    var output = document.getElementById('records');
    var html = '';
    var prevName;
    for(var i = 0; i < students.length; i++) {
        var current = students[i];
        if(current.name === input ) {
            html += '<h2>Student: ' + current.name + '</h2>';
            html += '<p>Track: ' + current.track + '</p>';
            html += '<p>Achievements: ' + current.achievements + '</p>';
            html += '<p>Points: ' + current.points + '</p>';
            print(html);
            prevName = current.name;
            current = '';
        } 

        else if(i === students.length - 1 && prevName === undefined){
            output.style.color = 'red';
            html += '<h1>' + input + ' is not a student</h1>';
            print(html);
            break;   
        }
    }
});
