Reference Text and Strings Javascript Web Browsers
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 ?
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.
127 and 155 are key codes of what keys
154
44
what is mean by keycode in javascript?
Great list! But I don't see the space bar. It is 32
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.

Thank you, I also needed that.
Thanks I needed it too!
Thanks me too :)
There's a whole lot of punctuation missing - !@#$%^&*()_+|:"<>?
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.
You can just block all !@# ... with e.shiftKey that will block once the user has pressed trhe shit key
thus you dont need to worry about those special characters
Excellent & very useful, thanks!!
I've made a script to create a full Javascript charcode table; see below:
<html>
<head>
<title>CharCodes do Javascript</title>
</head>
<body>
<table style="border: 1px solid black;" id="tabela1">
<thead>
<tr>
<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);
</script>

at last! it will work or no???
anyway - to fix code, is needed to add table with proper id.
Thank You Rafael! It's helpful script.
Very nice code I have added some color and borders to the table to make things stand out a bit
better. This is the code: <html> <head> <title>Javascript Char Codes</title> </head> <body>
<table id="tabela1" border="2"> <thead bgcolor="yellow"> <tr> <td colspan="2">Javascript

Thanks
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)
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?
dont think that may be a keycode, but another event property
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.
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?
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.
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:
http://jonathan.tang.name/code/js_keycode
The way you capture all the browser shortcut key is really nice.
How does that work?

I need the key code for the reload button in browser help me please! send email to
[email protected] Thanks in advance
You could use the function
charCodeAt
to get the code of a character
ex:
alert(String.charCodeAt('c'));
will alert 99
the code missing ascii value of some letters example Captial letters and print screen etc
any way it is helpful thnx
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.
forward slash : 191 notcorect
forward slash : 47 is corect
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)
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 ?
the forward slash is the combo of shift+number7.
What is char code for Mouse click
What is char code for Mouse click
Why don't you try typing a mouse click in the test box at the top of the page...
keys[173]="mute";
keys[174]="vol. down";
keys[175]="vol. up";
keys[176]="forward";
keys[177]="back";
keys[178]="stop";
keys[179]="play/pause";
this is very good
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:
http://unixpapa.com/js/key.html
I want the char code of Y and y, I don't know wheather the both are same or not.

This is wrong...
For Hyphen -> the key code is 45.
But here 45 is given for "insert" key.
:(
these are used like this
window.onkeydown=function(e)
;
works with keyup too

% and left arrow gives key code as 37. how to differenciate. i have different condition for

How can I write litte 2 on the top(for square function)?
char code 31?
How to set the NULL value in textbox if user press any key from 0-9..
Thanks in advance
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)

Hope you can help please. Require my Java script web page to transmit a CONTROL-F9. This
triggers a text to speech program to speak aloud complex, program created message. I think I
can use this script: function find() x = new ActiveXObject("WScript.Shell") x.SendKeys
(0x6600); I have been unable to confirm the VALUE of CONTROL-F9. Can you help?
Char code for comma is 44 also.... It works in both firefox and IE.
Hi, Thank for this great job. Anyone can help me ? I need to write the script to distinguish
upper from lower case letters ? I see that the Keycode for shift is 16 but how do I know
it's released ?
Use the onKeyUp event handler and test for keycode 16.
Using 74 for j doesn't work for me. I use 106 in my script and it works as j. Anyone know
why?
I have the same case as you! I am using this code to detect period and decimal point but it doesn't
work for me. I am using a Samsung laptop.
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.
Very useful content. Thanks a lot.!
How do I handle "shift"? like ")" = "shift 0"
great information .Thanks a lot for this http://csharpektroncmssql.blogspot.com

Please Provide the key code testing textbox for Combination keys. As of now the textbox is
jst taking single character. If shift + 0 is pressed to get the output of ) key code it does
not givs desired output
Key codes differ from character codes
u r download a nice coding
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.
