I am trying to alert the key which was pressed on both PC and mobile devices. However, on mobile devices, it returns the value “Unidentified”. Why is that?
$(document).on("keydown", function(e) {
alert(e.key);
});
On mobile devices, the keydown event does not provide the key property. Instead, you can use the keyCode or which property to get the code of the key that was pressed.
Here is an updated code snippet that should work on both PC and mobile devices:
$(document).on("keydown", function(e) {
alert(e.key || String.fromCharCode(e.keyCode || e.which));
});
This code first tries to get the key property, and if that is not available (i.e., on mobile devices), it uses the keyCode or which property and converts it into a character using String.fromCharCode().
