How to detect Ctrl + A press in a keyup event with JavaScript?
To detect Ctrl + A press in a keyup event with JavaScript, we can set the document.onkeyup
property to a function that checks for the pressing ctrl+a key combo.
For instance, we write:
document.onkeyup = (e) => {
if (e.ctrlKey && (e.keyCode == 65 || e.keyCode == 97)) {
console.log('ctrl+a pressed')
}
}
We set document.onkeyup
to a function that checks if ctrl is pressed with e.ctrlKey
.
And we check if the ‘a’ key is pressed with (e.keyCode == 65 || e.keyCode == 97)
.
If they’re both true
, then we know ctrl+a is pressed.

property to a function that checks for the pressing ctrl+a key combo.
