Summary

Javascript is often used on the browser client side to perform simple tasks that would otherwise require a full postback to the server. Many of those simple tasks involve processing text or characters entered into a form element on a web page, and it is often necessary to know the javascript keycode associated with a character. Here is a reference.

Press a key in the text box below to see the corresponding Javascript key code. Or scroll down to see the full list.

"Prnt Scrn SysRq " key code equals ?

joy

Reply 2007 Mar 01 22:59 PM by steve.

Ah, right. I forgot about that and had to go back and check.

The "Print Screen/SysRq" key appears to be a special case. All the keycodes above fire in at least the onKeyDown event. However the Print Screen Key does not fire the onKeyDown or onKeyPress events. It does sometimes fire the onKeyUp event when the page is freshly loaded. This behavior appears the same in IE6 and Firefox.

When it does fire (intermittently) the keycode is 44.

what is mean by keycode in javascript?

Great list! But I don't see the space bar. It is 32

Pat Markland

Reply 2007 Mar 13 21:31 PM by steve.

Thanks for the kudos! Somehow it missed the list. I'll have to update that. If you enter the space bar in the textbox above it works and the keycode is 32.

There's a whole lot of punctuation missing - !@#$%^&*()_+{}|:"<>?

Bill

Replied 2007 May 17 14:28 PM by Adam.

That is because punctuation doesn't let off a key code of their own. A key code refers to the key the user pushed, not the output of the key. Example: a period (.) is keycode 190. If you make a > that would be the same keycode because it is triggered off the same key.

      <table style="border: 1px solid black;" id="tabela1">

               <td colspan="2">Tabela de CharCodes</td>
            </tr>
         </thead>
         <TBODY></TBODY>
      </table>
   <body>
<html>
<script type="Text/Javascript">
   var tabela = document.getElementById("tabela1");
   var tbody = tabela.getElementsByTagName("TBODY")[0];

for (var i = 0; i <= 1000; i++) {
      var row = document.createElement("TR");
      var td1 = document.createElement("TD");
      td1.appendChild(document.createTextNode(i + " "));

      var td2 = document.createElement("TD");
      td2.appendChild(document.createTextNode(String.fromCharCode(i) + " "));

      row.appendChild(td1);
      row.appendChild(td2);
      tbody.appendChild(row);

Semi-colon is "59" on Firefox, not "186", so you need to capture both for compatibility. (Not that many folks need to capture ";", but I did for navigational reasons... umbrare.com)

Derek Detweiler

Reply 2007 Aug 02 21:38 PM by steve.

Good point. I see that the text box above gets it right for both cases, but the table does not include 59 for Firefox. Thanks!

how about the left click mouse button key?

Replied 2007 Nov 22 07:42 AM by lotuzwine.

dont think that may be a keycode, but another event property

Replied 2008 Jan 09 11:15 AM by Quaza.

its not, instead of a keycode, use on(press) or on(release) if its a button, and onDown if its a movie clip. If its a click anywhere activator, then use onMouseDown.

Replied 2008 Mar 14 15:52 PM by Jason Miller.

This isn't flash/ActionScript, you dolt. textarea.onmousedown=function(e){ if(!e) e=window.event; if((e.which&&e.which!=2) || (e.button&&e.button!=2)) // Left click (actually, just a *non* right-click. };

Is it possible to capture scrolling up, down or clicking down with the scroll wheel on a mouse?

Will

Replied 2008 Sep 17 08:34 AM by Benjamin M. A'Lee.

You might check mouse buttons 3 (middle-click) 4 (scroll up), and 5 (scroll down). At least, that's what they appear as outside of Javascript.

Posted 2008 Oct 19 13:57 PM.

Key codes are heavily dependent upon browsers. There's a full table available at:

http://unixpapa.com/js/key.html

There's also a library that normalizes keycodes into a consistent set, available at:

You could use the function
charCodeAt
to get the code of a character
ex:
alert(String.charCodeAt('c'));
will alert 99

This list is only for keycodes not characters. It identifies your keyboard keys, not key combinations. Shift-c for example does not belong in this list.

Posted 2009 May 24 06:27 AM.

forward slash : 191 notcorect
forward slash : 47 is corect

amir

Posted 2009 Aug 05 06:04 AM.

The position of the special characters depends on the language of the keyboard, so that might have an effect on which key gives which code. For example the Finnish keyboard has / (backslash) where this code presents ' (semicolon), and American keyboards naturally don't have å, ä or ö. You should keep in mind that hard-coding the positions of the special characters is language dependent. Think of it like this: Javascript can only determine "this is the 13th key on the second row on the keyboard", it can't tell what character is actually printed on that key.

press 5 on numpad (numlock off)

Anonymous

Reply 2010 Jan 27 13:08 PM by steve.

I wouldn't call it missing. Your keyboard doesn't give the num5 on the keypad any meaning when the numlock is off so we don't show a "name." But the keycode of 12 is shown so the key could still be handled by javascript code.

key code for @ and _?

Why if i insert ,in javascript ,the block of the forward slash (char code 191) i can't use the key 7 ?

I would like to point out that these are not standard across browsers for example:
- or _ is:

firefox: 109
IE : 189
Opera : 45
Chrome/Safari : 45(without shift) / 95 (with shift)

As you can see many keys can be drastically different.

there is a great article here about the maddness that is javascript key events:

How to set the NULL value in textbox if user press any key from 0-9..
Thanks in advance

Dharmendra

Posted 2011 Aug 29 20:07 PM.

I'm assuming no key press has a Javascript key code that equals zero?

I have a mask over a text field that ensures the only text entered is numeric. For automated testing, trying to put characters here only recognises the key code truncated to a single digit, not the character. So 1 = 4, z = 9 and so on and so forth. If there were some way to get a 0 I would be set.

(fixing the issue in flash would be more work)

Posted 2011 Dec 01 08:43 AM.

Key codes only represent individual keys - not combinations. They also can vary greatly depending on the layout of your keyboard. At work I use a Dell QWERTY 12-function keyboard with 3 sections, and this list is accurate for that.

This is an awesome article...I appreciate your effort for creating such a nice utility. Here we have a problem with Shift key combination. When ever you press Shift + <!> = Shift + 1 which is not an expected output. All special special characters which are on top of numerics are treated as numerics and given same KeyCode. Please help us in this matter.
