JavaScript to detect the key code number of a key that was pressed on the keyboard
Mark
you can use JavaScript to detect the key code number of a key that was pressed on the keyboard. Here is a basic example:
<script>
document.addEventListener('keydown', logKey);
function logKey(e) {
var keyCodeElement = document.getElementById("keyCode");
keyCodeElement.textContent = e.keyCode;
}
</script>
<p>Press a key to see its key code:</p>
<p>Key code: <span id="keyCode"></span></p>
In this example, we've added a span
element with an id
of keyCode
to the HTML markup. When a key is pressed, the logKey()
function updates the text content of the span
element with the key code value using the textContent
property.
Note that the keyCode
property is deprecated in newer versions of JavaScript, and it is recommended to use the key
property instead. However, the keyCode
property is still widely supported in current browsers, so it should work for your needs.
