Detect Key Pressed – Javascript onkeypress keycode
Hey friends, today we will see how to make this cool fun project. Let’s see how it works.
When the page is displayed, an interface like the below appears:
The user can then click any key on their keyboard and it will be captured/detected by the software. For example, when I click the shift key, it will display the following interface:
Now let’s see the source codes!
HTML & JS CODES
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>Detect Pressed Key in JavaScript</title>
<link rel="stylesheet" href="style.css">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div class="box">
<p class="text">Press any key</p>
<div class="content">
<div class="key-code"></div>
<div class="key-name"></div>
<div class="details">
<p class="key">Key: <span></span></p>
<p class="code">Code: <span></span></p>
</div>
</div>
</div>
<script>
const box = document.querySelector(".box");
document.addEventListener("keydown", e =>{
let keyName = e.keyCode === 32 ? "Space" : e.key;
box.querySelector(".key-code").innerText = e.keyCode;
box.querySelector(".key-name").innerText = keyName.toUpperCase();
box.querySelector(".key span").innerText = keyName;
box.querySelector(".code span").innerText = e.keyCode;
box.classList.add("active");
});
</script>
</body>
</html>
</body>
</html>
The output would be:
It will still work since we have added JavaScript, but we use CSS for styling it.
