It also respects special keys like shift etc. When a non-printable or special character is pressed, the value will be on of the defined key values like 'Shift' or 'Multiply'. I know this is an old question, but I came across it today searching for a pre-packaged solution to this problem, and found nothing that really met my needs. Here is a solution English only that correctly supports Upper Case shifted , Lower Case, punctuation, number keypad, etc.
It also allows for simple and straight-forward identification of - and reaction to - non-printable keys, like ESC, Arrows, Function keys, etc. Thanks to DaveAlger for saving me some typing - and much discovery! I recently wrote a module called keysight that translates keypress , keydown , and keyup events into characters and keys respectively.
For those of you who came here looking for the actual Unicode character values for a keycode, like I did, here is a function for that. Refer this link Get Keycode from key press and char value for any key code.

Viewed k times. I'm using jQuery. Improve this question. Casimir Crystal David Murdoch David Murdoch You must use keydown to capture character codes? You're in for a hell of a ride: quirksmode. The case of the character doesn't matter. And I need to capture up,down,left,right,esc,del,backspace for at least FF and IE; so keypress is out of the question. Thanks for the hint though. In response to this problem I just wrote a jQuery plugin: github.

It has been rightly pointed out that some keys like arrow keys, etc. But what I intended was how to convert the character to the string. Regarding the KeyCode, System. KeyEventArgs has a property KeyCode.
KeyEventArgs e. KeyEventArgs has a property KeyCode". Key is an enum with all th possible values. It contains the entire alfabet, in capital letters though, you can change them to small letters using ToLower. You can filter out any system keys with e.
Note however that the event will also be triggered for pressing any of thoses system keys. I found this code a couple years ago when looking for a solution to this question. The essential method in this class is GetCharFromKey. Found this thread when I was looking again for something that used fewer i.
See Gecko Keypress Event for details. In these cases, keyCode is set instead. To get the code of the key regardless of whether it was stored in keyCode or charCode , query the which property.

Connect and share knowledge within a single location that is structured and easy to search.
I need to figure out which character was typed into a text field from within the handler that is called by jQuery's keydown function. How do I do this? The keyPress event is what you need to get which character was entered. See below workaround for keydown event. Using jQuery e. Note I said jQuery's e. However you can write a simple workaround to get the pressed character working on keydown..

When the user releases the key, the keyup event is sent. When a key is pressed and held down, it begins to auto-repeat.
This results in a sequence of events similar to the following being dispatched:. The keydown and keyup events represent keys being pressed or released, while the keypress event represents a character being typed.
