How I can detect Key "Enter" on "input" event? [duplicate]

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);
}
}

Javascript - How to create a keypress event?

I've looked on the internet for this and all I can find are depreciated functions so before posting please check to make sure that the code you suggest isn't depreciated.
I've found this and tried it:
https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/KeyboardEvent
$(document).ready(function () {
var x = new KeyboardEvent("FormatCode", deprectiatedArgument);
});
But after further inspection the KeyboardEventInit is depreciated.
I would like to create an event on pres of the CTRL + K keys.

You have a specific key code for every button on the keyboard.
All of them are here http://keycode.info/.
$(document).keyup(function(e) {
if (e.keyCode === 13) function(); // enter
if (e.keyCode === 27) function(); // esc
});

Here's a vanilla JS solution to detect a CTRL + k keypress event:
UPDATED to also trigger the event.
document.addEventListener("keypress", function(e) {
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 11 || e.keyCode == 75)) {
alert("ctrl+k!");
}
});
document.getElementById("trigger").addEventListener("click", function(){
//trigger a keypress event...
var e = document.createEvent('HTMLEvents');
e.initEvent("keypress", false, true);
e.ctrlKey = true;
e.keyCode = 75;
document.dispatchEvent(e);
});
Press <kbd>ctrl+k</kbd> or
trigger the event

you can use a library called shortcut.js .. here is a link to their source code for downloading:
http://www.openjs.com/scripts/events/keyboard_shortcuts/shortcut.js
then run ur code by making this function:
shortcut.add("Ctrl+K",function() {
alert("Hi there!");
});
and here is the documentation : http://www.openjs.com/scripts/events/keyboard_shortcuts/
hope that can help.

$(document).ready(function () {
var bool = false;
$(document).keydown(function (e) {
if (e.keyCode === 17) {
bool = true;
}
if (bool == true && e.keyCode == 75) {
alert("");
}
});
$(document).keyup(function (e) {
if (e.keyCode === 17) {
bool = false;
}
});
});
This is how me and a friend got it working

Add keypress or eventlistener to input, "TypeError: ...addEventListener is not a function"

I'm working on a form where I do not want enter/return to submit the form so I used a function like this.
$('[name="form"]').keypress(function(e) {
var charCode = e.charcode || e.keyCode || e.which;
if (charCode === 13) {
e.preventDefault();
return false;
}
});
That works, but now I want to assign the enter/return to perform functions on two inputs on the form. I'm totally stuck.
To get the inputs I've tried vanilla js calling by id, jQ calling by id and then a mixer of the two with variables. I've also tried .keypress, .keydown, .keyup instead of the attachEventListener method. No matter what I do, I get this error in console.
"TypeError: ...addEventListener is not a function" (or keypress, keydown etc.)
I've also researched a good deal but can't find any solution. I appreciate any suggestions.
Here is this block of code in it's current form that's giving the trouble.
var yelpInput = $('#inputURL');
var googleInput = $('#googleURL');
yelpInput.addEventListener("keydown", function(e) {
if (e.keyCode === 13 ) {
alert('do stuff!');
}
});
// Google
googleInput.addEventListener("keydown", function(e) {
if (e.keyCode === 13 ) {
alert('do stuff!');
}
});
Thanks

var yelpInput = $('#inputURL');
var googleInput = $('#googleURL');
yelpInput.keydown(function(e) {
if (e.keyCode === 13 ) {
alert('do stuff!');
}
});
// Google
googleInput.keydown(function(e) {
if (e.keyCode === 13 ) {
alert('do stuff!');
}
});

yelpInput is jQuery wrapped object which does not have addEventListener method.
Use .on to attach event-handler on jQuery wrapped object or yelpInput[0].addEventListener/yelpInput.get(0).addEventListener to attach event using JavaScript as yelpInput[0] will be an DOMElement not jQuery-wrapped object.
var yelpInput = $('#inputURL');
var googleInput = $('#googleURL');
yelpInput.on("keydown", function(e) {
//-----^^^
if (e.keyCode === 13) {
alert('do stuff!');
}
});
googleInput.on("keydown", function(e) {
//-------^^^
if (e.keyCode === 13) {
alert('do stuff!');
}
});

Meteor Key Up event

I was using
Template.foo.rendered
$(document).keyup(function(e){
code here
})
But now I'm trying to use this!!
Template.foo.events
'keyup .overlay': function(e) {
if (e.keycode == 27) {
e.preventDefault();
$(".overlay").removeClass('overlay-open');
$(".overlay").addClass('overlay-hide');
}
}
However, it won't work... Any ideas?

Try this:
'keyup .overlay': function(e) {
if (e.keyCode == 27) {
e.preventDefault();
$(".overlay").removeClass('overlay-open');
$(".overlay").addClass('overlay-hide');
}
}

Jquery KeyPress Doesn't work

Any idea why this doesn't work whatsoever on any browser?
If i try it in jsfiddle it works.
$('#input_area').keypress(function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
HTML
<script type="text/javascript" src="counts.js"></script>
<script type="text/javascript" src="jquery-1.6.2.min.js"></script>
</head>
<body>
<input type="text" id="input_area"/>
</body>
JS
$(document).ready(function() {
$('#input_area').keypress(function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
});

I am ready to bet 5 bucks that you didn't wrap it in a document.ready handler in your actual application which jsfiddle does by default:
$(function() {
$('#input_area').keypress(function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
});
Another possibility is you forgot to reference jQuery or you referenced it from a wrong url.

Depending on the browser, the which property might not be implemented. You should also check for keyCode:
$(document).ready(function() {
$("#input_area").keypress(function (e) {
if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
alert('You pressed enter!');
}
});
});

If it works when running in jsfiddle, then it works. I suspect you're trying to register the keypress listener when the dom is not loaded yet, and input_area is not available yet. Wrap it inside $(document).ready :
$(document).ready(function() {
$('#input_area').keypress(function(e) {
if (e.which == 13) {
alert('You pressed enter!');
}
});
});

Try to use binding,
$('#input_area').bind('keypress', function(e){
alert(e.which);
});
