I would like to detect whether the user has pressed Enter using jQuery.
How is this possible? Does it require a plugin?
EDIT: It looks like I need to use the keypress()
method.
I wanted to know if anyone knows if there are browser issues with that command - like are there any browser compatibility issues I should know about?
This question is related to

Try this to detect the Enter key pressed.
$(document).on("keypress", function(e){
if(e.which == 13){
alert("You've pressed the enter key!");
}
});
See demo @ detect enter key press on keyboard
$(function(){
$('.modal-content').keypress(function(e){
debugger
var id = this.children[2].children[0].id;
if(e.which == 13) {
e.preventDefault();
$("#"+id).click();
}
})
});
I used $(document).on("keydown")
.
On some browsers keyCode
is not supported. The same with which
so if keyCode
is not supported you need to use which
and vice versa.
$(document).on("keydown", function(e) {_x000D_
const ENTER_KEY_CODE = 13;_x000D_
const ENTER_KEY = "Enter";_x000D_
var code = e.keyCode || e.which_x000D_
var key = e.key_x000D_
if (code == ENTER_KEY_CODE || key == ENTER_KEY) {_x000D_
console.log("Enter key pressed")_x000D_
}_x000D_
});

event.key
and modern JS!$(document).keypress(function(event) {
if (event.key === "Enter") {
// Do something
}
});
or without jQuery:
document.addEventListener("keypress", function onEvent(event) {
if (event.key === "Enter") {
// Do something better
}
});
I spent sometime coming up with this solution i hope it helps someone.
$(document).ready(function(){
$('#loginforms').keypress(function(e) {
if (e.which == 13) {
//e.preventDefault();
alert('login pressed');
}
});
$('#signupforms').keypress(function(e) {
if (e.which == 13) {
//e.preventDefault();
alert('register');
}
});
});
this my how I solved you shoud give return false;
$(document).on('keypress',function(e) {
if(e.which == 13) {
$('#sub_btn').trigger('click');
alert('You pressed a "enter" key in somewhere');
return false;
}
});

In some cases, you may need to suppress the ENTER key for a certain area of a page but not for other areas of a page, like the page below that contains a header <div>
with a SEARCH field.
It took me a bit to figure out how to do this, and I am posting this simple yet complete example up here for the community.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Test Script</title>
<script src="/lib/js/jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$('.container .content input').keypress(function (event) {
if (event.keyCode == 10 || event.keyCode == 13) {
alert('Form Submission needs to occur using the Submit button.');
event.preventDefault();
}
});
</script>
</head>
<body>
<div class="container">
<div class="header">
<div class="FileSearch">
<!-- Other HTML here -->
</div>
</div>
<div class="content">
<form id="testInput" action="#" method="post">
<input type="text" name="text1" />
<input type="text" name="text2" />
<input type="text" name="text3" />
<input type="submit" name="Submit" value="Submit" />
</form>
</div>
</div>
</body>
</html>
Link to JSFiddle Playground: The [Submit]
button does not do anything, but pressing ENTER from one of the Text Box controls will not submit the form.
The easy way to detect whether the user has pressed enter is to use key number the enter key number is =13 to check the value of key in your device
$("input").keypress(function (e) {
if (e.which == 32 || (65 <= e.which && e.which <= 65 + 25)
|| (97 <= e.which && e.which <= 97 + 25)) {
var c = String.fromCharCode(e.which);
$("p").append($("<span/>"))
.children(":last")
.append(document.createTextNode(c));
} else if (e.which == 8) {
// backspace in IE only be on keydown
$("p").children(":last").remove();
}
$("div").text(e.which);
});
by pressing the enter key you will get result as 13 . using the key value you can call a function or do whatever you wish
$(document).keypress(function(e) {
if(e.which == 13) {
console.log("User entered Enter key");
// the code you want to run
}
});
if you want to target a button once enter key is pressed you can use the code
$(document).bind('keypress', function(e){
if(e.which === 13) { // return
$('#butonname').trigger('click');
}
});
Hope it help
I think the simplest method would be using vanilla javacript:
document.onkeyup = function(event) {
if (event.key === 13){
alert("enter was pressed");
}
}
I couldn't get the code posted by @Paolo Bergantino to work but when I changed it to $(document)
and e.which
instead of e.keyCode
then I found it to work faultlessly.
$(document).keypress(function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
As the keypress
event isn't covered by any official specification, the actual behavior encountered when using it may differ across browsers, browser versions, and platforms.
$(document).keydown(function(event) {_x000D_
if (event.keyCode || event.which === 13) {_x000D_
// Cancel the default action, if needed_x000D_
event.preventDefault();_x000D_
//call function, trigger events and everything tou want to dd . ex : Trigger the button element with a click_x000D_
$("#btn").trigger('click');_x000D_
}_x000D_
})
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>_x000D_
<button id="btn" onclick="console.log('Button Pressed.')"> </button>
_x000D_
I hope it would be useful!
A minor extension of Andrea's answer above makes the helper method more useful when you may also want to capture modified enter presses (i.e. ctrl-enter or shift-enter). For example, this variant allows binding like:
$('textarea').enterKey(function() {$(this).closest('form').submit(); }, 'ctrl')
to submit a form when the user presses ctrl-enter with focus on that form's textarea.
$.fn.enterKey = function (fnc, mod) {
return this.each(function () {
$(this).keypress(function (ev) {
var keycode = (ev.keyCode ? ev.keyCode : ev.which);
if ((keycode == '13' || keycode == '10') && (!mod || ev[mod + 'Key'])) {
fnc.call(this, ev);
}
})
})
}
(see also Ctrl+Enter jQuery in TEXTAREA)
You can do this using the jquery 'keydown' event handle
$( "#start" ).on( "keydown", function(event) {
if(event.which == 13)
alert("Entered!");
});
I wrote a small plugin to make it easier to bind the "on enter key pressed" a event:
$.fn.enterKey = function (fnc) {
return this.each(function () {
$(this).keypress(function (ev) {
var keycode = (ev.keyCode ? ev.keyCode : ev.which);
if (keycode == '13') {
fnc.call(this, ev);
}
})
})
}
Usage:
$("#input").enterKey(function () {
alert('Enter!');
})
There's a keypress() event method. The Enter key's ascii number is 13 and is not dependent on which browser is being used.
$(document).keyup(function(e) {
if(e.key === 'Enter') {
//Do the stuff
}
});
$(document).keydown(function (event) {
//proper indentiation of keycode and which to be equal to 13.
if ( (event.keyCode || event.which) === 13) {
// Cancel the default action, if needed
event.preventDefault();
//call function, trigger events and everything tou want to dd . ex : Trigger the button element with a click
$("#btnsearch").trigger('click');
}
});
I found this to be more cross-browser compatible:
$(document).keypress(function(event) {
var keycode = event.keyCode || event.which;
if(keycode == '13') {
alert('You pressed a "enter" key in somewhere');
}
});
