Random name picker with Javascript : Mijo Kristo

Random name picker with Javascript

My wife and I will become parents. I believe most of the future parents have the same issue, we cannot agree about the name for our little son. 🙂 After a few days (weeks) we have made a long list of all the names we but some names that are in my short circuit are not even close to her 🙂 In the absence of idea I decided to make a name generator with JavaScript that will help us choose the name 🙂 Sweet ha?
Below is a whole code that I wrote, maybe will be useful to somebody.

Here is HTML

<h1 id="headerNames">?</h1>
<div class="button" id="startButton">start</div>
<div class="button" id="stopButton">stop</div>

Here is CSS

body {
background: #333;
}

h1#headerNames {
margin-top: 10%;
color: #fff;
font-family: Georgia, serif;
font-size: 150px;
text-align: center;
cursor: pointer;
}

.button {
width: 150px;
margin: auto;
padding: 20px;
background: #1fa91f;
border: 3px solid #fff;
border-radius: 10px;
color: #fff;
font-family: Arial, sans-serif;
font-size: 30px;
font-weight: bold;
text-align: center;
text-transform: uppercase;
letter-spacing: 2px;
display: block;
cursor: pointer;
}

#stopButton {
background: #ff0000;
display: none;
}

#timerWrapper {
margin: 50px 0;
color: #fff;
font-family: Arial, sans-serif;
font-size: 50px;
text-align: center;
opacity: 0;
transition: opacity 1s;
}
#timerWrapper.visible {
opacity: 1;
}

Here is Javascript

"use strict";
const showTimer = true;
// Add list of names here
const namesList = [
'Ivano',
'Lovro',
'Dominik', 
'Vid',
'Roko',
'Luka',
'Niko'
];

// Default variables
let i = 0;
let x = 0;
let intervalHandle = null;
const startButton = document.getElementById('startButton');
const stopButton = document.getElementById('stopButton');
const headerOne = document.getElementById('headerNames');

// Optional countdown timer
// Add zero in front of numbers < 10
function checkSecond(sec) {
  if (sec < 10 && sec >= 0) {
sec = "0" + sec;
} 
  if (sec < 0) {
sec = "59";
}
  return sec;
}
// Start or stop the name shuffle on the button click
startButton.addEventListener('click', function() {
this.style.display = "none";
stopButton.style.display = "block";
intervalHandle = setInterval(function () {
headerNames.textContent = namesList[i++ % namesList.length];
}, 50);
if (showTimer===true) {
timerWrapper.classList.remove('visible');
}
});
stopButton.addEventListener('click', function() {
this.style.display = "none";
startButton.style.display = "block";
clearInterval(intervalHandle);
timer.innerHTML = time;
if (showTimer===true) {
timerWrapper.classList.add('visible');
}
startTimer();
});

// Allow use of spacebar to start/stop name shuffle
document.body.onkeyup = function(e) {
if (e.keyCode == 32) {
if (x%2===0) {
startButton.style.display = "none";
stopButton.style.display = "block";
intervalHandle = setInterval(function () {
headerNames.textContent = namesList[i++ % namesList.length];
}, 50);
if (showTimer===true) {
timerWrapper.classList.remove('visible');
}
} else {
startButton.style.display = "block";
stopButton.style.display = "none";
clearInterval(intervalHandle);
timer.innerHTML = time;
if (showTimer===true) {
timerWrapper.classList.add('visible');
}
startTimer();
}
x++; 
}
}
