Keydown will give you the keyCode of the key pressed, without any modifications. $(“#keypresser”).keydown(function(e){ var keycode = e.keyCode; var valid = (keycode > 47 && keycode < 58) || // number keys keycode == 32 || keycode == 13 || // spacebar & return key(s) (if you want to allow carriage returns) (keycode > 64 … Read more

Below is a list of the common key codes for quick reference, taken from Events.h. If you need to use these keycodes in an application, you should include the Carbon framework: Objective-C: #include <Carbon/Carbon.h> Swift: import Carbon.HIToolbox You can then use the kVK_ANSI_A constants directly. WARNING The key constants reference physical keys on the keyboard. … Read more
In my experience String.fromCharCode(e.keyCode) is unreliable. String.fromCharCode expects unicode charcodes as an argument; e.keyCode returns javascript keycodes. Javascript keycodes and unicode charcodes are not the same thing! In particular, the numberpad keys return a different keycode from the ordinary number keys (since they are different keys) while the same keycode is returned for both upper … Read more
For instance if you want to detect whether the “Enter”-key was clicked or not: Instead of event.keyCode === 13 Do it like event.key === ‘Enter’
