Hello, guys In this tutorial we will try to solve above mention query. and also we will learn how to create a Stopwatch using HTML CSS and JavaScript.
First, we need to create three files index.html and style.css then we need to do code for it.
Step:1
Add below code inside index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Create a Stopwatch in JavaScript</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta https-equiv="X-UA-Compatible" content="ie=edge" />
<link rel="stylesheet" href="style.css" />
<link rel="preconnect" href="https://fonts.gstatic.com">
<link href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@200;300;400&display=swap" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<div class="wrapper">
<div id="stopwatch">00:00:00:00</div>
<ul id="buttons">
<li><button id="start">Start</button></li>
<li><button id="pause">Stop</button></li>
<li><button id="reset">Reset</button></li>
</ul>
</div>
<script>
const watch = document.querySelector("#stopwatch");
let millisecound = 0;
let timer;
function timeStart(){
watch.style.color = "#0f62fe";
clearInterval(timer);
timer = setInterval(() => {
millisecound += 10;
let dateTimer = new Date(millisecound);
watch.innerHTML =
('0'+dateTimer.getUTCHours()).slice(-2) + ':' +
('0'+dateTimer.getUTCMinutes()).slice(-2) + ':' +
('0'+dateTimer.getUTCSeconds()).slice(-2) + ':' +
('0'+dateTimer.getUTCMilliseconds()).slice(-3,-1);
}, 10);
}
function timePaused() {
watch.style.color = "red";
clearInterval(timer);
}
function timeReset(){
setInterval(timer)
millisecound = 0;
watch.innerHTML = "00:00:00:00";
}
document.addEventListener('click', (e) => {
const el = e.target;
if(el.id === 'start') timeStart();
if(el.id === 'pause') timePaused();
if(el.id === 'reset') timeReset();
})
</script>
</body>
</html>
Step:2
Then we need to add code for style.css which code I provide in the below screen.
* {
padding: 0;
margin: 0;
-webkit-box-sizing: border-box;
box-sizing: border-box;
font-family: 'IBM Plex Sans', sans-serif;
}
body {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
background: #f2f4f6;
}
.wrapper {
width: 400px;
padding: 20px;
background: #fff;
box-shadow: 0 10px 20px rgb(64 64 64 / 5%);
border: 1px solid rgb(64 64 64 / 5%);
}
div#stopwatch {
font-size: 50px;
line-height: 60px;
text-align: center;
padding: 0 0 50px 0;
}
ul#buttons {
list-style: none;
display: flex;
align-items: center;
justify-content: space-between;
}
ul#buttons button {
background: #0f62fe;
border: transparent;
width: 100px;
color: #fff;
font-size: 18px;
text-align: left;
display: block;
padding: 10px 0 10px 20px;
cursor: pointer;
}
