How to make the event when the Esc key is pressed; please give me an example of an alert ();.
document.body.onkeyup = function(e){
if(e.keyCode == 27){
alert('Yay');
}
}
if your interested in using jquery,
check this code
<script type="text/javascript">
$("CssSelector").on("keyup", HandleKeyEvent(e));
function HandleKeyEvent(e)
{
if ( e.keyCode == 27 && e.key == "Escape" )
{
//--> Do Something
alert("It Works");
}
} );
</script>
Sorry I have just realized that this is an old question from 2011.

I am trying to detect enter key press inside tinmyce editor and it's working fine for all the keys but its not working for enter key.
setup : function (instance) {
instance.on("keypress", function(e) {
var Keycode = (e.keyCode ? e.keyCode : e.which);
alert(Keycode);
});
}
In above code its alerting all the keys except ENTER. i don't know whats the issue there.
keypress wasn't working for me , but keydown worked for me.
setup : function (instance) {
instance.on("keydown", function(e) {
var Keycode = (e.keyCode ? e.keyCode : e.which);
alert(Keycode);
});
}
I think this will work, i've tested it and it works in this fiddle with jquery 2.24
$(document).keypress(function(e) {
if (e.which == 13) {
console.log('You pressed enter!');
} else {
console.log('You pressed ' + e.which);
}
});
body {
height: 500px;
width:500px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
</body>
EDIT: Sorry i only noticed after that this was also tagged as tinymce
I think you can do this by slightly adjusting your function
//tinyMCE.init({
setup : function(instance) {
instance.onKeyDown.add(function(instance, event) {
if (event.keyCode == 13) { //enter
event.preventDefault();
event.stopPropagation();
//do stuff here
//alert("Enter!");
}
else{ alert (event.keyCode);}
});
}
//});
EDIT 2:
In the current tiny mce docs, there is an example of a function [in setup].
maybe try
tinymce.init({
selector: 'textarea', // change this value according to your HTML
setup: function(instance) {
instance.on('keypress', function(e) {
if (event.keyCode == 13) { //enter
event.preventDefault();
event.stopPropagation();
//do stuff here
//alert("Enter!");
}
else{ alert (event.keyCode);}
});
}
});
note the tinymce is now all lowercase..
Try this :
$(function () {
$("#MYTEXTBOX").keyup(function (e) {
alert(e.keyCode);
});
});
onkeypress does not detect some special keys like ctrl, shift arrow keys etc. Use onkeypress or onekyup instead.
Application I am going to implement have a shortcut key-f4(Client Request).When I click f4 all the previous url's is listed.I want to disable this..Pls help me....
Try this
document.onkeydown = keydown;
function keydown(evt){
if (!evt) evt = event;
if (evt.keyCode==115){
return false;
}
}
<script type="text/javascript">
document.onkeydown=function(e) {
e=e||window.event;
if (e.keyCode === 115 ) {
e.keyCode = 0;
alert("This action is not allowed");
if(e.preventDefault)e.preventDefault();
else e.returnValue = false;
return false;
}
}
</script>
You can use the keydown event of jscript.
$(document).ready(function () {
$(window).keydown(function(event){
if (event.keyCode == 115) {
event.preventDefault();
}
});
}); //Document .ready closed
document.addEventListener('keydown', function (e) {
if (e.keyCode == 115) {
console.log('F4 pressed');
e.preventDefault();
}
});
$("#username,#password").keypress(function(e)
{
//alert('');
if(e.keyCode == 13)
{
signIn();
}
});
The keypress event not calling if the enter button is pressed.
Try using keyUp event.
Live Demo
$("#username,#password").keyup(function(e){
//alert('');
if(e.keyCode == 13)
{
signIn();
}
});
This is also working with keypress
Live Demo
$("#txt1").keypress(function(e) {
if (e.keyCode == 13) {
//signIn();
alert("keypress");
}
});
Key down is more appropriate:
$("#username,#password").keydown(function(e){
if(e.keyCode == 13)
{
signIn();
}
});
Use e.which instead of e.keyCode because this is what jQuery guarantees to be on event
Try e.preventDefault(), because without it (if they are in a form) the form submits
Maybe the best would be listening on form's submit event
Are you sure it's not the signIn (); function that's faulty? Because this seems to work just fine; http://jsfiddle.net/vDkBs/1/
Use keypress and which statement:
$("#username,#password").keypress(function(e) {
if (e.which == 13) {
//call here your function
}
});
I have one text box when user enter in text box and hit enter it should alert the value, and also if user change the value it should also alert. So there will be two events keypress and change. And I want call this with minimum code. no duplicate codes.
$('#txt').keydown(function (e){
if(e.keyCode == 13){
alert('you pressed enter ^_^');
}
})
Online Demo
You can list multiple events as the first parameter (though you still have to handle each event):
$('#txt').bind('keypress change', function (e){
if(e.type === 'change' || e.keyCode == 13) {
alert('you pressed enter ^_^');
}
});
I'm using bind on purpose, because the OTs fiddle uses jQ 1.5.2
This is how I would approach this problem.
http://jsfiddle.net/tThq5/3/
Notes: I'm using $.live() (v.1.3) rather than $.on() (v1.7) and also returning false so I don't get more than 1 event fired.
$('#txt').live('keypress change', function(e) {
if (e.type === 'keypress' && e.keyCode == 13) {
alert('you pressed enter');
return false;
} else if (e.type === 'change') {
alert('you made a change');
return false;
}
});
Something like this?
$('#txt')
.keydown(function (e) {
if(e.keyCode == 13){
alert('you pressed enter ^_^');
}
})
.change(function(e) {
alert('you changed the text ^_-');
});
Try the live approach:
$("#txt").live({
change: function(e) {
alert('you changed the value');
},
keydown: function(e) {
if (e.keyCode == 13) {
alert('you pressed enter ^_^');
}
}
});

I'm trying to do a function if enter is pressed while on specific input.
What I'm I doing wrong?
$(document).keyup(function (e) {
if ($(".input1").is(":focus") && (e.keyCode == 13)) {
// Do something
}
});
Is there a better way of doing this which would say, if enter pressed on .input1 do function?
$(".input1").on('keyup', function (e) {
if (e.key === 'Enter' || e.keyCode === 13) {
// Do something
}
});
// e.key is the modern way of detecting keys
// e.keyCode is deprecated (left here for for legacy browsers support)
// keyup is not compatible with Jquery select(), Keydown is.
event.key === "Enter"
More recent and much cleaner: use event.key. No more arbitrary number codes!
NOTE: The old properties (.keyCode and .which) are Deprecated.
const node = document.getElementsByClassName("input1")[0];
node.addEventListener("keyup", function(event) {
if (event.key === "Enter") {
// Do work
}
});
Modern style, with lambda and destructuring
node.addEventListener("keyup", ({key}) => {
if (key === "Enter") {
// Do work
}
})
If you must use jQuery:
$(document).keyup(function(event) {
if ($(".input1").is(":focus") && event.key == "Enter") {
// Do work
}
});
Mozilla Docs
Supported Browsers
$(document).keyup(function (e) {
if ($(".input1:focus") && (e.keyCode === 13)) {
alert('ya!')
}
});
Or just bind to the input itself
$('.input1').keyup(function (e) {
if (e.keyCode === 13) {
alert('ya!')
}
});
To figure out which keyCode you need, use the website http://keycode.info
Try this to detect the Enter key pressed in a textbox.
$(function(){
$(".input1").keyup(function (e) {
if (e.which == 13) {
// Enter key pressed
}
});
});
The best way I found is using keydown ( the keyup doesn't work well for me).
Note: I also disabled the form submit because usually when you like to do some actions when pressing Enter Key the only think you do not like is to submit the form :)
$('input').keydown( function( event ) {
if ( event.which === 13 ) {
// Do something
// Disable sending the related form
event.preventDefault();
return false;
}
});
It may be too late to answer this question. But the following code simply prevents the enter key. Just copy and paste should work.
<script type="text/javascript">
function stopRKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 13) && (node.type=="text")) {return false;}
}
document.onkeypress = stopRKey;
</script>
The solution that work for me is the following
$("#element").addEventListener("keyup", function(event) {
if (event.key === "Enter") {
// do something
}
});
Try this to detect the Enter key pressed in a textbox.
$(document).on("keypress", "input", function(e){
if(e.which == 13){
alert("Enter key pressed");
}
});
DEMO
A solution that worked for me is this:
<input onkeydown="if (event.key == 'Enter'){//do logic}else{}">
$(document).ready(function () {
$(".input1").keyup(function (e) {
if (e.keyCode == 13) {
// Do something
}
});
});
This code handled every input for me in the whole site. It checks for the ENTER KEY inside an INPUT field and doesn't stop on TEXTAREA or other places.
$(document).on("keydown", "input", function(e){
if(e.which == 13){
event.preventDefault();
return false;
}
});
Here is what I did for my angular project:
HTML:
<input
class="form-control"
[(ngModel)]="searchFirstName"
(keyup)="keyUpEnter($event)"
/>
TypeScript:
keyUpEnter(event: KeyboardEvent) {
if (event.key == 'Enter') {
console.log(event);
}
}
