7. I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section). Here's the link:
Otherwise, the code of the pressed key is stored in keyCode. keyCode is always set in the keydown and keyup events. In these cases, charCode is never set. To get the code of the key regardless of whether it was stored in keyCode or charCode, query the which property. Characters entered through an IME do not register through keyCode or charCode.
Here was proposed to use key value instead of keyCode and if it fails then use keyCode. Though this is not enough, because values in this attributes are not compatible. Thing is new key contains the string for control keys, like: ArrowUp, but keyCode will contain just code which with trivial. String.fromCharCode(event.keyCode)
If browser supprts e.keyCode then take e.keyCode else e.charCode. It is similar to. var code = event.keyCode || event.charCode event.keyCode: Returns the Unicode value of a non-character key in a keypress event or any key in any other type of keyboard event. event.charCode: Returns the Unicode value of a character key pressed during a keypress ...
5. If you are looking for an online tool, https://keyjs.dev is probably the best option available: By default, it displays e.key, e.code, e.which and e.keyCode for the keydown event. If you need more than that, you can expand it and you will get a table with more properties for keydown, keypress and keyup. If you still need more than that, open ...
In the case of this question: event.key will return the same output ("Enter") for both the 'carriage return' and 'numpad enter'keys, while event.code will return "Enter" and "NumpadEnter" respectively. In this case, if you wanted to differentiate between numpad and keyboard keys, you could use event.code. If you wanted their operation to be the ...
To add to some of the other answers, note that: keyup and keydown differ from keypress; if you want to use String.fromCharCode() to get the actual digit from keyup, you'll need to first normalize the keyCode.
118. 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.
Nov 22, 2016 at 6:09. 1. There is a really simple trick to find out whichever keyCode you want. Just open a new tab, put document.addEventListener("keydown", e => console.log(e.keyCode)) into your browser console, click into the window and press the key you are looking for. – Wu Wei.
For values of keyCode <= 96 it seems to map using the function: chrCode = keyCode - 48 * Math.floor(keyCode / 48) For values of keyCode > 96 it seems to map using the function: chrCode = keyCode. If this seems like odd behavior then well..I agree. Sadly enough, it would be very far from the weirdest thing I've seen in the JS core.
