I have a form with two text boxes, one select drop down and one radio button. When the enter key is pressed, I want to call my JavaScript function, but when I press it, the form is submitted.
How do I prevent the form from being submitted when the enter key is pressed?
if(characterCode == 13) {
// returning false will prevent the event from bubbling up.
return false;
} else{
return true;
}
Ok, so imagine you have the following textbox in a form:
<input id="scriptBox" type="text" onkeypress="return runScript(event)" />
In order to run some "user defined" script from this text box when the enter key is pressed, and not have it submit the form, here is some sample code. Please note that this function doesn't do any error checking and most likely will only work in IE. To do this right you need a more robust solution, but you will get the general idea.
function runScript(e) {
//See notes about 'which' and 'key'
if (e.keyCode == 13) {
var tb = document.getElementById("scriptBox");
eval(tb.value);
return false;
}
}
returning the value of the function will alert the event handler not to bubble the event any further, and will prevent the keypress event from being handled further.
NOTE:
It's been pointed out that keyCode is now deprecated. The next best alternative which has also been deprecated.
Unfortunately the favored standard key, which is widely supported by modern browsers, has some dodgy behavior in IE and Edge. Anything older than IE11 would still need a polyfill.
Furthermore, while the deprecated warning is quite ominous about keyCode and which, removing those would represent a massive breaking change to untold numbers of legacy websites. For that reason, it is unlikely they are going anywhere anytime soon.
Use both event.which and event.keyCode:
function (event) {
if (event.which == 13 || event.keyCode == 13) {
//code to execute here
return false;
}
return true;
};
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("mySelect")[0];
node.addEventListener("keydown", function(event) {
if (event.key === "Enter") {
event.preventDefault();
// Do more work
}
});
Modern style, with lambda and destructuring
node.addEventListener("keydown", ({key}) => {
if (key === "Enter") // Handle press
})

If you're using jQuery:
$('input[type=text]').on('keydown', function(e) {
if (e.which == 13) {
e.preventDefault();
}
});
Detect Enter key pressed on whole document:
$(document).keypress(function (e) {
if (e.which == 13) {
alert('enter key is pressed');
}
});

Override the onsubmit action of the form to be a call to your function and add return false after it, ie:
<form onsubmit="javascript:myfunc();return false;" >
A react js solution
handleChange: function(e) {
if (e.key == 'Enter') {
console.log('test');
}
<div>
<Input type="text"
ref = "input"
placeholder="hiya"
onKeyPress={this.handleChange}
/>
</div>
So maybe the best solution to cover as many browsers as possible and be future proof would be
if (event.which === 13 || event.keyCode === 13 || event.key === "Enter")
Here is how you can do it using JavaScript:
//in your **popup.js** file just use this function
var input = document.getElementById("textSearch");
input.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
alert("yes it works,I'm happy ");
}
});
<!--Let's say this is your html file-->
<!DOCTYPE html>
<html>
<body style="width: 500px">
<input placeholder="Enter the text and press enter" type="text" id="textSearch"/>
<script type="text/javascript" src="public/js/popup.js"></script>
</body>
</html>
Below code will add listener for ENTER key on entire page.
This can be very useful in screens with single Action button eg Login, Register, Submit etc.
<head>
<!--Import jQuery IMPORTANT -->
<script src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<!--Listen to Enter key event-->
<script type="text/javascript">
$(document).keypress(function (e) {
if (e.which == 13 || event.keyCode == 13) {
alert('enter key is pressed');
}
});
</script>
</head>
Tested on all browsers.
A jQuery solution.
I came here looking for a way to delay the form submission until after the blur event on the text input had been fired.
$(selector).keyup(function(e){
/*
* Delay the enter key form submit till after the hidden
* input is updated.
*/
// No need to do anything if it's not the enter key
// Also only e.which is needed as this is the jQuery event object.
if (e.which !== 13) {
return;
}
// Prevent form submit
e.preventDefault();
// Trigger the blur event.
this.blur();
// Submit the form.
$(e.target).closest('form').submit();
});
Would be nice to get a more general version that fired all the delayed events rather than just the form submit.
A much simpler and effective way from my perspective should be :
function onPress_ENTER()
{
var keyPressed = event.keyCode || event.which;
//if ENTER is pressed
if(keyPressed==13)
{
alert('enter pressed');
keyPressed=null;
}
else
{
return false;
}
}
A little simple
Don't send the form on keypress "Enter":
<form id="form_cdb" onsubmit="return false">
Execute the function on keypress "Enter":
<input type="text" autocomplete="off" onkeypress="if(event.key === 'Enter') my_event()">
Using TypeScript, and avoid multiples calls on the function
let el1= <HTMLInputElement>document.getElementById('searchUser');
el1.onkeypress = SearchListEnter;
function SearchListEnter(event: KeyboardEvent) {
if (event.which !== 13) {
return;
}
// more stuff
}
<div class="nav-search" id="nav-search">
<form class="form-search">
<span class="input-icon">
<input type="text" placeholder="Search ..." class="nav-search-input" id="search_value" autocomplete="off" />
<i class="ace-icon fa fa-search nav-search-icon"></i>
</span>
<input type="button" id="search" value="Search" class="btn btn-xs" style="border-radius: 5px;">
</form>
</div>
<script type="text/javascript">
$("#search_value").on('keydown', function(e) {
if (e.which == 13) {
$("#search").trigger('click');
return false;
}
});
$("#search").on('click',function(){
alert('You press enter');
});
</script>
native js (fetch api)
document.onload = (() => {

let keyListener = document.querySelector('#searchUser');
//

Cross Browser Solution
Some older browsers implemented keydown events in a non-standard way.
KeyBoardEvent.key is the way it is supposed to be implemented in modern browsers.
which
and keyCode are deprecated nowadays, but it doesn't hurt to check for these events nonetheless so that the code works for users that still use older browsers like IE.
The isKeyPressed function checks if the pressed key was enter and event.preventDefault() hinders the form from submitting.
if (isKeyPressed(event, 'Enter', 13)) {
event.preventDefault();
console.log('enter was pressed and is prevented');
}
Minimal working example
JS
function isKeyPressed(event, expectedKey, expectedCode) {
const code = event.which || event.keyCode;
if (expectedKey === event.key || code === expectedCode) {
return true;
}
return false;
}
document.getElementById('myInput').addEventListener('keydown', function(event) {
if (isKeyPressed(event, 'Enter', 13)) {
event.preventDefault();
console.log('enter was pressed and is prevented');
}
});
HTML
<form>
<input id="myInput">
</form>
https://jsfiddle.net/tobiobeck/z13dh5r2/
Use event.preventDefault() inside user defined function
<form onsubmit="userFunction(event)"> ...
function userFunction(ev)
{
if(!event.target.send.checked)
{
console.log('form NOT submit on "Enter" key')
ev.preventDefault();
}
}
Open chrome console> network tab to see
<form onsubmit="userFunction(event)" action="/test.txt">
<input placeholder="type and press Enter" /><br>
<input type="checkbox" name="send" /> submit on enter
</form>
I used document on, which covers dynamically added html after page load:
$(document).on('keydown', '.selector', function (event) {
if (event.which == 13 || event.keyCode == 13) {
//do your thang
}
});

How do I make it so that when I press enter on a text input, it calls a function? I tried using this:
<input type="text" onkeypress="clickPress()">
But the problem is I only want to press enter to call that function, not press any key. How do I achieve that?
2022 Update: onkeypress is deprecated.
You can use onKeyDown instead
What you'd want to do is check whether the event's key is the enter key:
In your html, add the event argument
<input type="text" onkeypress="clickPress(event)">
And in your handler, add an event parameter
function clickPress(event) {
if (event.keyCode == 13) {
// do something
}
}
2022 Update: event.keyCode is deprecated on many browsers.
You should do this now:
function clickPress(event) {
if (event.key == "Enter") {
// do something
}
}
Use a form instead (the submit event only runs once instead of every key press):
// Attach the event handler to the form element
document.querySelector('.js-form')?.addEventListener('submit', e => {
e.preventDefault();
alert(e.currentTarget.myText.value);
});
<form class="js-form">
<input type="text" name="myText">
</form>
The Enter button has a keyCode of 13, so you can use the keypress event using jQuery
$("input").keypress(function(event) {
if (event.which == 13) {
alert("Enter was pressed");
}
});
or, in pure javascript:
<input type="text" onkeypress="clickPress(event)">
function clickPress(event) {
if (event.keyCode == 13) {
// do something
}
}
Get the event's keycode and test if it's enter (keycode 13)
<script>
function clickPress(e){
if (event.keyCode == 13) {
// Enter was pressed
alert("enter");
}
}
</script>
<input type="text" onkeypress="clickPress(event)" />
jsfiddle
There could be several "better" ways to do what you want to do but just for the sake of simplicity, you could do this:
<input type="text" id="txt">
Instead of listening to the onkeypress you could attach an event listener within the <script></script> tags and do this:
var myText = document.getElementById("txt");
myText.addEventListener("keyup", function(e) {
if (e.which === 13) {
//The keycode for enter key is 13
alert(e.target.value);
}
});
And yeah this is definitely a duplicate question.
I have an input field <input type="text" name="input" /> outside of a form so that it is not submit when the user presses enter. I want to know when the user presses enter without submitting so that I can run some JavaScript. I want this to work in all major browsers (I don't care about IE though) and be valid JavaScript.
FYI: jQuery is an option
I will not use jQuery and this is going to work in IE < 9 too. With jQuery or other frameworks you may have some simpler ways to attach event listeners.
var input = document.getElementsByName("input")[0];
if (input.addEventListener)
input.addEventListener("keypress", function(e) {
if (e.keyCode === 13) {
// do stuff
e.preventDefault();
}
}, false);
else if (input.attachEvent)
input.attachEvent("onkeypress", function(e) {
if (e.keyCode === 13) {
// do stuff
return e.returnValue = false;
}
});
$("input[name='input']").keypress(function(e) {
//13 maps to the enter key
if (e.keyCode == 13) {
doSomeAwesomeJavascript();
}
})
function doSomeAwestomeJavascript() {
//Awesome js happening here.
}
I would like to detect whether the user has pressed Enter using jQuery.
How is this possible? Does it require a plugin?
It looks like I need to use the keypress() method.
Are there browser issues with that command - like are there any browser compatibility issues I should know about?
The whole point of jQuery is that you don't have to worry about browser differences. I am pretty sure you can safely go with enter being 13 in all browsers. So with that in mind, you can do this:
$(document).on('keypress',function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
I wrote a small plugin to make it easier to bind the "on enter key pressed" 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!');
})
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!');
}
});
Link to example on JS Bin
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');
}
});
You can do this using the jQuery 'keydown' event handler:
$("#start").on("keydown", function(event) {
if(event.which == 13)
alert("Entered!");
});
Use event.key and modern JavaScript!
$(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
}
});
Mozilla documentation
Supported Browsers
I came up with this solution:
$(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');
}
});
});
There's a keypress() event method. The Enter key's ASCII number is 13 and is not dependent on which browser is being used.
A minor extension of Andrea's answer 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 using jQuery in a TEXTAREA)
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.

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.
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
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) {
if (event.keyCode || event.which === 13) {
// Cancel the default action, if needed
event.preventDefault();
// Call function, trigger events and everything you want to do. Example: Trigger the button element with a click
$("#btn").trigger('click');
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<button id="btn" onclick="console.log('Button Pressed.')"> </button>
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) {
const ENTER_KEY_CODE = 13;
const ENTER_KEY = "Enter";
var code = e.keyCode || e.which
var key = e.key
if (code == ENTER_KEY_CODE || key == ENTER_KEY) {
console.log("Enter key pressed")
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
$(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');
}
});
This my how I solved it. You should use return false;
$(document).on('keypress', function(e) {
if(e.which == 13) {
$('#sub_btn').trigger('click');
alert('You pressed the "Enter" key somewhere');
return false;
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

I think the simplest method would be using vanilla JavaScript:
document.onkeyup = function(event) {
if (event.key === 13){
alert("Enter was pressed");
}
}
The easy way to detect whether the user has pressed Enter is to use the key number. The Enter key number is equal to 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 Internet Explorer only is 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("The user pressed the Enter key");
// The code you want to run
}
});
If you want to target a button once the Enter key is pressed, you can use the code:
$(document).bind('keypress', function(e) {
if(e.which === 13) { // Return
$('#buttonname').trigger('click');
}
});
$(document).keyup(function(e) {
if(e.key === 'Enter') {
//Do the stuff
}
});
$(function(){
$('.modal-content').keypress(function(e){
debugger
var id = this.children[2].children[0].id;
if(e.which == 13) {
e.preventDefault();
$("#"+id).click();
}
})
});
I have a bog-standard login form - an email text field, a password field and a submit button on an AIR project that's using HTML/jQuery. When I hit Enter on the form, the entire form's contents vanish, but the form isn't submitted. Does anyone know if this is a Webkit issue (Adobe AIR uses Webkit for HTML), or if I've bunged things up?
I tried:
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
}
});
But that neither stopped the clearing behavior, or submitted the form. There's no action associated with the form - could that be the issue? Can I put a javascript function in the action?
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
return false; //<---- Add this line
}
});
Check out this stackoverflow answer:
event.preventDefault() vs. return false
Essentially, "return false" is the same as calling e.preventDefault and e.stopPropagation().
In addition to return false as Jason Cohen mentioned. You may have to also preventDefault
e.preventDefault();
Don't know if it will help, but you can try simulating a submit button click, instead of directly submitting the form. I have the following code in production, and it works fine:
$('.input').keypress(function(e) {
if(e.which == 13) {
jQuery(this).blur();
jQuery('#submit').focus().click();
}
});
Note: jQuery('#submit').focus() makes the button animate when enter is pressed.
Return false to prevent the keystroke from continuing.
Is there any reason you have to hook and test for the enter key?
Couldn't you simply add a
<input type="submit" />
to your form and have it naturally be submitted when enter is pushed? You could even then hook the form's onsubmit action and call a validation function from there if you wanted...
You could even use the onsubmit as a test to see if your form is being submitted, but it won't work if you call form.submit().
Here's a way to do this as a JQuery plugin (in case you want to re-use the functionality):
$.fn.onEnterKey =
function( closure ) {
$(this).keypress(
function( event ) {
var code = event.keyCode ? event.keyCode : event.which;
if (code == 13) {
closure();
return false;
}
} );
}
Now if you want to decorate an <input> element with this type of functionality it's as simple as this:
$('#your-input-id').onEnterKey(
function() {
// Do stuff here
} );
You can also simply add onsubmit="return false" to the form code in the page to prevent the default behaviour.
Then hook (.bind or .live) the form's submit event to any function with jQuery in the javascript file.
Here's a sample code to help:
HTML
<form id="search_form" onsubmit="return false">
<input type="text" id="search_field"/>
<input type="button" id="search_btn" value="SEARCH"/>
</form>
Javascript + jQuery
$(document).ready(function() {
$('#search_form').live("submit", function() {
any_function()
});
});
This is working as of 2011-04-13, with Firefox 4.0 and jQuery 1.4.3
This is my code:
$("#txtMessage").on( "keypress", function(event) {
if (event.which == 13 && !event.shiftKey) {
event.preventDefault();
$("#frSendMessage").submit();
}
});
Also to maintain accessibility, you should use this to determine your keycode:
c = e.which ? e.which : e.keyCode;
if (c == 13) ...
Just adding for easy implementation. You can simply make a form and then make the submit button hidden:
For example:
<form action="submit.php" method="post">
Name : <input type="text" name="test">
<input type="submit" style="display: none;">
</form>
I use now
$("form").submit(function(event){
...
}
At first I added an eventhandler to the submit button which produced an error for me.
I found out today the keypress event is not fired when hitting the Enter key, so you might want to switch to keydown() or keyup() instead.
My test script:
$('.module input').keydown(function (e) {
var keyCode = e.which;
console.log("keydown ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keyup(function (e) {
var keyCode = e.which;
console.log("keyup ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keypress(function (e) {
var keyCode = e.which;
console.log("keypress ("+keyCode+")");
if (keyCode == 13) {
console.log("Enter");
return false;
}
});
The output in the console when typing "A Enter B" on the keyboard:
keydown (65)
keypress (97)
keyup (65)
keydown (13)
enter
keyup (13)
enter
keydown (66)
keypress (98)
keyup (66)
You see in the second sequence the 'keypress' is missing, but keydown and keyup register code '13' as being pressed/released.
As per jQuery documentation on the function keypress():
Note: 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.

As it may be late
but you can add below line in html:-
<input onkeyup="submitForm(event)" oninput="addTextName(this)" type="text" id="name-val">
and add this on js file
function submitForm(e) {
var keyCode = e.keyCode ? e.keyCode : e.which;
if (keyCode == 13){
toggleNextScreen();
}
}
keycode 13 means enter
In HTML codes:
<form action="POST" onsubmit="ajax_submit();return false;">
<b>First Name:</b> <input type="text" name="firstname" id="firstname">
<br>
<b>Last Name:</b> <input type="text" name="lastname" id="lastname">
<br>
<input type="submit" name="send" onclick="ajax_submit();">
</form>
In Js codes:
function ajax_submit()
{
$.ajax({
url: "submit.php",
type: "POST",
data: {
firstname: $("#firstname").val(),
lastname: $("#lastname").val()
},
dataType: "JSON",
success: function (jsonStr) {
// another codes when result is success
}
});
}
$('form#login').keypress(function (e) {
var keyCode = e.keyCode ? e.keyCode : e.which;
if (keyCode == 13)
{
e.preventDefault();
$('form#login').submit();
return false;
}
});
Try this:
var form = document.formname;
if($(form).length > 0)
{
$(form).keypress(function (e){
code = e.keyCode ? e.keyCode : e.which;
if(code.toString() == 13)
{
formsubmit();
}
})
}
I have one text input and one button (see below). How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box?
There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the Enter key to click this specific button if it is pressed from within this one text box, nothing else.
<input type="text" id="txtSearch" />
<input type="button" id="btnSearch" value="Search" onclick="doSomething();" />
In jQuery, the following would work:
$("#id_of_textbox").keyup(function(event) {
if (event.keyCode === 13) {
$("#id_of_button").click();
}
});
$("#pw").keyup(function(event) {
if (event.keyCode === 13) {
$("#myButton").click();
}
});
$("#myButton").click(function() {
alert("Button code executed.");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Username:<input id="username" type="text"><br>
Password: <input id="pw" type="password"><br>
<button id="myButton">Submit</button>
Or in plain JavaScript, the following would work:
document.getElementById("id_of_textbox")
.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
document.getElementById("id_of_button").click();
}
});
document.getElementById("pw")
.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
document.getElementById("myButton").click();
}
});
function buttonCode()
{
alert("Button code executed.");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Username:<input id="username" type="text"><br>
Password: <input id="pw" type="password"><br>
<button id="myButton" onclick="buttonCode()">Submit</button>
Then just code it in!
<input type = "text"
id = "txtSearch"
onkeydown = "if (event.keyCode == 13)
document.getElementById('btnSearch').click()"
/>
<input type = "button"
id = "btnSearch"
value = "Search"
onclick = "doSomething();"
/>
Figured this out:
<input type="text" id="txtSearch" onkeypress="return searchKeyPress(event);" />
<input type="button" id="btnSearch" Value="Search" onclick="doSomething();" />
<script>
function searchKeyPress(e)
{
// look for window.event in case event isn't passed in
e = e || window.event;
if (e.keyCode == 13)
{
document.getElementById('btnSearch').click();
return false;
}
return true;
}
</script>
Make the button a submit element, so it'll be automatic.
<input type = "submit"
id = "btnSearch"
value = "Search"
onclick = "return doSomething();"
/>
Note that you'll need a <form> element containing the input fields to make this work (thanks Sergey Ilinsky).
It's not a good practice to redefine standard behaviour, the Enter key should always call the submit button on a form.
Since no one has used addEventListener yet, here is my version. Given the elements:
<input type = "text" id = "txt" />
<input type = "button" id = "go" />
I would use the following:
var go = document.getElementById("go");
var txt = document.getElementById("txt");
txt.addEventListener("keypress", function(event) {
event.preventDefault();
if (event.keyCode == 13)
go.click();
});
This allows you to change the event type and action separately while keeping the HTML clean.
Note that it's probably worthwhile to make sure this is outside of a <form> because when I enclosed these elements in them pressing Enter submitted the form and reloaded the page. Took me a few blinks to discover.
Addendum: Thanks to a comment by #ruffin, I've added the missing event handler and a preventDefault to allow this code to (presumably) work inside a form as well. (I will get around to testing this, at which point I will remove the bracketed content.)
In plain JavaScript,
if (document.layers) {
document.captureEvents(Event.KEYDOWN);
}
document.onkeydown = function (evt) {
var keyCode = evt ? (evt.which ? evt.which : evt.keyCode) : event.keyCode;
if (keyCode == 13) {
// For Enter.
// Your function here.
}
if (keyCode == 27) {
// For Escape.
// Your function here.
} else {
return true;
}
};
I noticed that the reply is given in jQuery only, so I thought of giving something in plain JavaScript as well.
Use keypress and event.key === "Enter" with modern JS!
const textbox = document.getElementById("txtSearch");
textbox.addEventListener("keypress", function onEvent(event) {
if (event.key === "Enter") {
document.getElementById("btnSearch").click();
}
});
Mozilla Docs
Supported Browsers
One basic trick you can use for this that I haven't seen fully mentioned. If you want to do an ajax action, or some other work on Enter but don't want to actually submit a form you can do this:
<form onsubmit="Search();" action="javascript:void(0);">
<input type="text" id="searchCriteria" placeholder="Search Criteria"/>
<input type="button" onclick="Search();" value="Search" id="searchBtn"/>
</form>
Setting action="javascript:void(0);" like this is a shortcut for preventing default behavior essentially. In this case a method is called whether you hit enter or click the button and an ajax call is made to load some data.
To trigger a search every time the enter key is pressed, use this:
$(document).keypress(function(event) {
var keycode = (event.keyCode ? event.keyCode : event.which);
if (keycode == '13') {
$('#btnSearch').click();
}
}
Try it:
<input type="text" id="txtSearch"/>
<input type="button" id="btnSearch" Value="Search"/>
<script>
window.onload = function() {
document.getElementById('txtSearch').onkeypress = function searchKeyPress(event) {
if (event.keyCode == 13) {
document.getElementById('btnSearch').click();
}
};
document.getElementById('btnSearch').onclick =doSomething;
}
</script>
onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('btnSearch').click();}};"
This is just something I have from a somewhat recent project... I found it on the net, and I have no idea if there's a better way or not in plain old JavaScript.
Although, I'm pretty sure that as long as there is only one field in the form and one submit button, hitting enter should submit the form, even if there is another form on the page.
You can then capture the form onsubmit with js and do whatever validation or callbacks you want.
This is a solution for all the YUI lovers out there:
Y.on('keydown', function() {
if(event.keyCode == 13){
Y.one("#id_of_button").simulate("click");
}
}, '#id_of_textbox');
In this special case I did have better results using YUI for triggering DOM objects that have been injected with button functionality - but this is another story...
In modern, undeprecated (without keyCode or onkeydown) Javascript:
<input onkeypress="if(event.key == 'Enter') {console.log('Test')}">
In Angular2:
(keyup.enter)="doSomething()"
If you don't want some visual feedback in the button, it's a good design to not reference the button but rather directly invoke the controller.
Also, the id isn't needed - another NG2 way of separating between the view and the model.
Short working pure JS
txtSearch.onkeydown= e => (e.key=="Enter") ? btnSearch.click() : 1
txtSearch.onkeydown= e => (e.key=="Enter") ? btnSearch.click() : 1
function doSomething() {
console.log('💩');
}
<input type="text" id="txtSearch" />
<input type="button" id="btnSearch" value="Search" onclick="doSomething();" />
This in-case you want also diable the enter button from Posting to server and execute the Js script.
<input type="text" id="txtSearch" onkeydown="if (event.keyCode == 13)
{document.getElementById('btnSearch').click(); return false;}"/>
<input type="button" id="btnSearch" value="Search" onclick="doSomething();" />
Nobody noticed the html attibute "accesskey" which is available since a while.
This is a no javascript way to keyboard shortcuts stuffs.
The accesskey attributes shortcuts on MDN
Intented to be used like this. The html attribute itself is enough, howewer we can change the placeholder or other indicator depending of the browser and os. The script is a untested scratch approach to give an idea. You may want to use a browser library detector like the tiny bowser
let client = navigator.userAgent.toLowerCase(),
isLinux = client.indexOf("linux") > -1,
isWin = client.indexOf("windows") > -1,
isMac = client.indexOf("apple") > -1,
isFirefox = client.indexOf("firefox") > -1,
isWebkit = client.indexOf("webkit") > -1,
isOpera = client.indexOf("opera") > -1,
input = document.getElementById('guestInput');
if(isFirefox) {
input.setAttribute("placeholder", "ALT+SHIFT+Z");
} else if (isWin) {
input.setAttribute("placeholder", "ALT+Z");
} else if (isMac) {
input.setAttribute("placeholder", "CTRL+ALT+Z");
} else if (isOpera) {
input.setAttribute("placeholder", "SHIFT+ESCAPE->Z");
} else {'Point me to operate...'}
<input type="text" id="guestInput" accesskey="z" placeholder="Acces shortcut:"></input>
This onchange attempt is close, but misbehaves with respect to browser back then forward (on Safari 4.0.5 and Firefox 3.6.3), so ultimately, I wouldn't recommend it.
<input type="text" id="txtSearch" onchange="doSomething();" />
<input type="button" id="btnSearch" value="Search" onclick="doSomething();" />
event.returnValue = false
Use it when handling the event or in the function your event handler calls.
It works in Internet Explorer and Opera at least.
To add a completely plain JavaScript solution that addressed #icedwater's issue with form submission, here's a complete solution with form.
NOTE: This is for "modern browsers", including IE9+. The IE8 version isn't much more complicated, and can be learned here.
Fiddle: https://jsfiddle.net/rufwork/gm6h25th/1/
HTML
<body>
<form>
<input type="text" id="txt" />
<input type="button" id="go" value="Click Me!" />
<div id="outige"></div>
</form>
</body>
JavaScript
// The document.addEventListener replicates $(document).ready() for
// modern browsers (including IE9+), and is slightly more robust than `onload`.
// More here: https://stackoverflow.com/a/21814964/1028230
document.addEventListener("DOMContentLoaded", function() {
var go = document.getElementById("go"),
txt = document.getElementById("txt"),
outige = document.getElementById("outige");
// Note that jQuery handles "empty" selections "for free".
// Since we're plain JavaScripting it, we need to make sure this DOM exists first.
if (txt && go) {
txt.addEventListener("keypress", function (e) {
if (event.keyCode === 13) {
go.click();
e.preventDefault(); // <<< Most important missing piece from icedwater
}
});
go.addEventListener("click", function () {
if (outige) {
outige.innerHTML += "Clicked!<br />";
}
});
}
});
For jQuery mobile, I had to do:
$('#id_of_textbox').live("keyup", function(event) {
if(event.keyCode == '13'){
$('#id_of_button').click();
}
});
For those who may like brevity and modern js approach.
input.addEventListener('keydown', (e) => {if (e.keyCode == 13) doSomething()});
where input is a variable containing your input element.
document.onkeypress = function (e) {
e = e || window.event;
var charCode = (typeof e.which == "number") ? e.which : e.keyCode;
if (charCode == 13) {
// Do something here
printResult();
}
};
Heres my two cents. I am working on an app for Windows 8 and want the button to register a click event when I press the Enter button. I am doing this in JS. I tried a couple of suggestions, but had issues. This works just fine.
To do it with jQuery:
$("#txtSearch").on("keyup", function (event) {
if (event.keyCode==13) {
$("#btnSearch").get(0).click();
}
});
To do it with normal JavaScript:
document.getElementById("txtSearch").addEventListener("keyup", function (event) {
if (event.keyCode==13) {
document.getElementById("#btnSearch").click();
}
});
In jQuery, you can use event.which==13. If you have a form, you could use $('#formid').submit() (with the correct event listeners added to the submission of said form).
$('#textfield').keyup(function(event){
if(event.which==13){
$('#submit').click();
}
});
$('#submit').click(function(e){
if($('#textfield').val().trim().length){
alert("Submitted!");
} else {
alert("Field can not be empty!");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="textfield">
Enter Text:</label>
<input id="textfield" type="text">
<button id="submit">
Submit
</button>
These day the change event is the way!
document.getElementById("txtSearch").addEventListener('change',
() => document.getElementById("btnSearch").click()
);
My reusable Vanilla JS solution. so you can change which button gets hit depending on what element/textbox is active.
<input type="text" id="message" onkeypress="enterKeyHandler(event,'sendmessage')" />
<input type="button" id="sendmessage" value="Send"/>
function enterKeyHandler(e,button) {
e = e || window.event;
if (e.key == 'Enter') {
document.getElementById(button).click();
}
}
You can try below code in jQuery.
$("#txtSearch").keyup(function(e) {
e.preventDefault();
var keycode = (e.keyCode ? e.keyCode : e.which);
if (keycode === 13 || e.key === 'Enter')
{
$("#btnSearch").click();
}
});
I have developed custom javascript to achieve this feature by just adding class
Example: <button type="button" class="ctrl-p">Custom Print</button>
Here Check it out Fiddle
// find elements
var banner = $("#banner-message")
var button = $("button")
// handle click and add class
button.on("click", function(){
if(banner.hasClass("alt"))
banner.removeClass("alt")
else
banner.addClass("alt")
})
$(document).ready(function(){
$(document).on('keydown', function (e) {
if (e.ctrlKey) {
$('[class*="ctrl-"]:not([data-ctrl])').each(function (idx, item) {
var Key = $(item).prop('class').substr($(item).prop('class').indexOf('ctrl-') + 5, 1).toUpperCase();
$(item).attr("data-ctrl", Key);
$(item).append('<div class="tooltip fade top in tooltip-ctrl alter-info" role="tooltip" style="margin-top: -61px; display: block; visibility: visible;"><div class="tooltip-arrow" style="left: 49.5935%;"></div><div class="tooltip-inner"> CTRL + ' + Key + '</div></div>')
});
}
if (e.ctrlKey && e.which != 17) {
var Key = String.fromCharCode(e.which).toLowerCase();
if( $('.ctrl-'+Key).length == 1) {
e.preventDefault();
if (!$('#divLoader').is(":visible"))
$('.ctrl-'+Key).click();
console.log("You pressed ctrl + "+Key );
}
}
});
$(document).on('keyup', function (e) {
if(!e.ctrlKey ){
$('[class*="ctrl-"]').removeAttr("data-ctrl");
$(".tooltip-ctrl").remove();
}
})
});
