With jQuery, how do I find out which key was pressed when I bind to the keypress event?
$('#searchbox input').bind('keypress', function(e) {});
I want to trigger a submit when ENTER is pressed.
[Update]
Even though I found the (or better: one) answer myself, there seems to be some room for variation ;)
Is there a difference between keyCode
and which
- especially if I'm just looking for ENTER, which will never be a unicode key?
Do some browsers provide one property and others provide the other one?

If you are using jQuery UI you have translations for common key codes. In ui/ui/ui.core.js:
$.ui.keyCode = {
...
ENTER: 13,
...
};
There's also some translations in tests/simulate/jquery.simulate.js but I could not find any in the core JS library. Mind you, I merely grep'ed the sources. Maybe there is some other way to get rid of these magic numbers.
You can also make use of String.charCodeAt and .fromCharCode:
>>> String.charCodeAt('\r') == 13
true
>>> String.fromCharCode(13) == '\r'
true
Try this
$('#searchbox input').bind('keypress', function(e) {
if(e.keyCode==13){
// Enter pressed... do anything here...
}
});
I have just made a plugin for jQuery that allows easier keypress
events. Instead of having to find the number and put it in, all you have to do is this:
$(document).keydown(function(e) {
if (getPressedKey(e) == theKeyYouWantToFireAPressEventFor /*Add 'e.ctrlKey here to only fire if the combo is CTRL+theKeyYouWantToFireAPressEventFor'*/) {
// Your Code To Fire When You Press theKeyYouWantToFireAPressEventFor
}
});
It's that simple. Please note that theKeyYouWantToFireAPressEventFor
is not a number, but a string (e.g "a"
to fire when A is pressed, "ctrl"
to fire when CTRL (control) is pressed, or, in the case of a number, just 1
, no quotes. That would fire when 1 is pressed.)
function getPressedKey(e){var a,s=e.keyCode||e.which,c=65,r=66,o=67,l=68,t=69,f=70,n=71,d=72,i=73,p=74,u=75,h=76,m=77,w=78,k=79,g=80,b=81,v=82,q=83,y=84,j=85,x=86,z=87,C=88,K=89,P=90,A=32,B=17,D=8,E=13,F=16,G=18,H=19,I=20,J=27,L=33,M=34,N=35,O=36,Q=37,R=38,S=40,T=45,U=46,V=91,W=92,X=93,Y=48,Z=49,$=50,_=51,ea=52,aa=53,sa=54,ca=55,ra=56,oa=57,la=96,ta=97,fa=98,na=99,da=100,ia=101,pa=102,ua=103,ha=104,ma=105,wa=106,ka=107,ga=109,ba=110,va=111,qa=112,ya=113,ja=114,xa=115,za=116,Ca=117,Ka=118,Pa=119,Aa=120,Ba=121,Da=122,Ea=123,Fa=114,Ga=145,Ha=186,Ia=187,Ja=188,La=189,Ma=190,Na=191,Oa=192,Qa=219,Ra=220,Sa=221,Ta=222;return s==Fa&&(a="numlock"),s==Ga&&(a="scrolllock"),s==Ha&&(a="semicolon"),s==Ia&&(a="equals"),s==Ja&&(a="comma"),s==La&&(a="dash"),s==Ma&&(a="period"),s==Na&&(a="slash"),s==Oa&&(a="grave"),s==Qa&&(a="openbracket"),s==Ra&&(a="backslash"),s==Sa&&(a="closebracket"),s==Ta&&(a="singlequote"),s==B&&(a="ctrl"),s==D&&(a="backspace"),s==E&&(a="enter"),s==F&&(a="shift"),s==G&&(a="alt"),s==H&&(a="pause"),s==I&&(a="caps"),s==J&&(a="esc"),s==L&&(a="pageup"),s==M&&(a="padedown"),s==N&&(a="end"),s==O&&(a="home"),s==Q&&(a="leftarrow"),s==R&&(a="uparrow"),s==S&&(a="downarrow"),s==T&&(a="insert"),s==U&&(a="delete"),s==V&&(a="winleft"),s==W&&(a="winright"),s==X&&(a="select"),s==Z&&(a=1),s==$&&(a=2),s==_&&(a=3),s==ea&&(a=4),s==aa&&(a=5),s==sa&&(a=6),s==ca&&(a=7),s==ra&&(a=8),s==oa&&(a=9),s==Y&&(a=0),s==ta&&(a=1),s==fa&&(a=2),s==na&&(a=3),s==da&&(a=4),s==ia&&(a=5),s==pa&&(a=6),s==ua&&(a=7),s==ha&&(a=8),s==ma&&(a=9),s==la&&(a=0),s==wa&&(a="times"),s==ka&&(a="add"),s==ga&&(a="minus"),s==ba&&(a="decimal"),s==va&&(a="devide"),s==qa&&(a="f1"),s==ya&&(a="f2"),s==ja&&(a="f3"),s==xa&&(a="f4"),s==za&&(a="f5"),s==Ca&&(a="f6"),s==Ka&&(a="f7"),s==Pa&&(a="f8"),s==Aa&&(a="f9"),s==Ba&&(a="f10"),s==Da&&(a="f11"),s==Ea&&(a="f12"),s==c&&(a="a"),s==r&&(a="b"),s==o&&(a="c"),s==l&&(a="d"),s==t&&(a="e"),s==f&&(a="f"),s==n&&(a="g"),s==d&&(a="h"),s==i&&(a="i"),s==p&&(a="j"),s==u&&(a="k"),s==h&&(a="l"),s==m&&(a="m"),s==w&&(a="n"),s==k&&(a="o"),s==g&&(a="p"),s==b&&(a="q"),s==v&&(a="r"),s==q&&(a="s"),s==y&&(a="t"),s==j&&(a="u"),s==x&&(a="v"),s==z&&(a="w"),s==C&&(a="x"),s==K&&(a="y"),s==P&&(a="z"),s==A&&(a="space"),a}_x000D_

Because the long version is so... well... long, I have made a PasteBin link for it:

... this example prevents form submission (regularly the basic intention when capturing keystroke #13):
$('input#search').keypress(function(e) {
if (e.which == '13') {
e.preventDefault();
doSomethingWith(this.value);
}
});
According to Kilian's answer:
If only enter key-press is important:
<form action="javascript:alert('Enter');">
<input type=text value="press enter">
</form>
// in jquery source code...
if (!event.which && ((event.charCode || event.charCode === 0) ? event.charCode : event.keyCode)) {
event.which = event.charCode || event.keyCode;
}
// So you have just to use
$('#searchbox input').bind('keypress', function(e) {
if (e.which === 13) {
alert('ENTER WAS PRESSED');
}
});
event.key
and modern JS!No number codes anymore. You can check key directly. For example "Enter"
, "LeftArrow"
, "r"
, or "R"
.
const input = document.getElementById("searchbox");
input.addEventListener("keypress", function onEvent(event) {
if (event.key === "Enter") {
// Submit
}
else if (event.key === "Q") {
// Play quacking duck sound, maybe...
}
});
Add hidden submit, not type hidden, just plain submit with style="display:none". Here is an example (removed unnecessary attributes from code).
<form>
<input type="text">
<input type="submit" style="display:none">
</form>
it will accept enter key natively, no need for JavaScript, works in every browser.
Here's a jquery extension that will handle the enter key being pressed.
(function ($) {
$.prototype.enterPressed = function (fn) {
$(this).keyup(function (e) {
if ((e.keyCode || e.which) == 13) {
fn();
}
});
};
}(jQuery || {}));
$("#myInput").enterPressed(function() {
//do something
});

Okay, I was blind:

Some browsers use keyCode, others use which. If you're using jQuery, you can reliably use which as jQuery standardizes things. Actually,
$('#searchbox input').bind('keypress', function(e) {
if(e.keyCode==13){
}
});
Given that you are using jQuery, you should absolutely use .which. Yes different browsers set different properties, but jQuery will normalize them and set the .which value in each case. See documetation at http://api.jquery.com/keydown/ it states:
To determine which key was pressed, we can examine the event object that is passed to the handler function. While browsers use differing properties to store this information, jQuery normalizes the .which property so we can reliably use it to retrieve the key code.

I realize this is an old posting, but someone might find this useful.
The key events are mapped, so instead of using the keycode value you can also use the key value to make it a little more readable.
$(document).ready( function() {
$('#searchbox input').keydown(function(e)
{
setTimeout(function ()
{
//rather than using keyup, you can use keydown to capture
//the input as it's being typed.
//You may need to use a timeout in order to allow the input to be updated
}, 5);
});
if(e.key == "Enter")
{
//Enter key was pressed, do stuff
}else if(e.key == "Spacebar")
{
//Spacebar was pressed, do stuff
}
});
Here is a cheat sheet with the mapped keys which I got from this blog
Okay, I was blind:
e.which
will contain the ASCII code of the key.

I have just made a plugin for jQuery that allows easier keypress
events. Instead of having to find the number and put it in, all you have to do is this:
$(document).keydown(function(e) {
if (getPressedKey(e) == theKeyYouWantToFireAPressEventFor /*Add 'e.ctrlKey here to only fire if the combo is CTRL+theKeyYouWantToFireAPressEventFor'*/) {
// Your Code To Fire When You Press theKeyYouWantToFireAPressEventFor
}
});
It's that simple. Please note that theKeyYouWantToFireAPressEventFor
is not a number, but a string (e.g "a"
to fire when A is pressed, "ctrl"
to fire when CTRL (control) is pressed, or, in the case of a number, just 1
, no quotes. That would fire when 1 is pressed.)

Because the long version is so... well... long, I have made a PasteBin link for it:

you should have firbug to see a result in console

Try this:
jQuery('#myInput').keypress(function(e) {
code = e.keyCode ? e.keyCode : e.which;
if(code.toString() == 13) {
alert('You pressed enter!');
}
});
Here is an at-length description of the behaviour of various browsers http://unixpapa.com/js/key.html
Given that you are using jQuery, you should absolutely use .which. Yes different browsers set different properties, but jQuery will normalize them and set the .which value in each case. See documetation at http://api.jquery.com/keydown/ it states:
To determine which key was pressed, we can examine the event object that is passed to the handler function. While browsers use differing properties to store this information, jQuery normalizes the .which property so we can reliably use it to retrieve the key code.
The easiest way that I do is:
$("#element").keydown(function(event) {
if (event.keyCode == 13) {
localiza_cep(this.value);
}
});
