How to handle multiple buttons enter key functionality? - javascript

In my page there are two buttons. For enter key functionality I have written the following jQuery code.
$(function () {
$("#first-button-id").keyup(function (e) {
if (e.keyCode == '13') {
e.preventDefault();
}
}).focus();
$("#second-button-id").keyup(function (e) {
if (e.keyCode == '13') {
e.preventDefault();
}
}).focus();
});
But always when click on enter key first one is firing. Please tell me how to handle the multiple button enter key functionality.

Try something like this
HTML :
<label>TextBox : </label>
<input id="textbox" type="text" size="50" />
<label>TextBox 2: </label>
<input id="textbox2" type="text" size="50" />
JQuery
$('#textbox , #textbox2').keyup(function(event){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == '13'){
alert('You pressed a "enter" key in textbox');
}
event.preventDefault();
}).focus();
DEMO
Some browser prefer keycode and other use which ... I suggest you to use both..

You do not need to focus on two buttons at the same time. Try doing something like this:
$("#button1").keypress(function(event){
if ( event.which == 13 ){
//Do something}
$("#button2").keypress(function(event){
if( event.which == 13 ){
//Do something else}
The problem i think is with your event.preventDefault() function which stops the propogation of the event once a function is executed. In your case, your first function might be getting completed before the second one and hence the second one gets aborted in the middle.

$("#first-button-id , #second-button-id ").keyup(function(event){
if ( event.which == 13 ) {
alert("you pressed enter.");
event.preventDefault();
}
}

The reason the first submit button is always firing is because that's the default behavior of a web page which you haven't actually altered with your code.
Try this:
$(function () {
$("#first-button-id, #second-button-id").keyup(function (e) {
e.preventDefault();
e.stopImmediatePropagation();
if (e.keyCode == '13') {
$(this).trigger("click");
}
});
});
What you seem to be asking about strikes me as rather odd. It looks like you want second-button to be 'clicked' if the focus is on second-button and enter is pressed. Tabbing until the focus is on the correct button is really the only practical way this could happen.

Try this.
$('#first-button-id').on("keydown", function (e)
{
if (e.keyCode == 13)
{
e.preventDefault();
$("first-button-id").click();
}
});

ie11 Detecting Enter Key pressed

I have the following piece of code in an asp mvc page
$('#regForm').submit(function (event) {
if (event.keyCode == '13') {
event.preventDefault();
}
});
The aim is to prevent the form from submitting when enter is pressed.
We have noticed that in ie 11, this is not working, and on stepping into the code via debug, event.keycode is null. I have been doing some researching on this, and it seems to be an issue because we have the IE-8 Compatibility Meta Tag present on the page, which means that event.keyCode (and event.which) returns undefined for the event, and so my form is always submitted.
So how do I rewrite this to get round the issue?
You need to use the keypress event, not form submit
$('#regForm').keypress(function (event) {
if (event.keyCode == 13) {
event.preventDefault();
}
});
Try something like this, use window.event:
$('#regForm').submit(function (e) {
var keyCode = (window.event) ? e.which : e.keyCode;
if (keyCode == '13') {
e.preventDefault();
}
});
Use type="button" attribute with <button> element
So that IE thinks the button as a simple button instead of a submit button.
So form will not submit
You can also get more details from below url
http://tjvantoll.com/2013/01/01/enter-should-submit-forms-stop-messing-with-that/
$('#regForm').keypress((event) => {
if (event.key === "Enter") {
event.preventDefault();
}
});

Default button on enter and popup list

I'm trying to implement a form with multiple buttons on it. When I press enter I want to have my default button submitted. This code from http://greatwebguy.com/programming/dom/default-html-button-submit-on-enter-with-jquery/ generally works:
$(function() {
$("form input").keypress(function (e) {
if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
$('button[type=submit].default').click();
return false;
} else {
return true;
}
});
});
but...
when I type in input field I have an autocomplete popup so when I press enter in this popup I expect to put this value to input field, not submit all form. Can I check somehow if this enter comes from popup? Or I should try to do this different way?
EDIT:
I think I didn't say it clear. This popup is not any part of jquery. It's standard popup that shows previously typed data into input. So it hasn't got any class nor id. Stop propagation doesn't work either. None of solutions below resolve this problem
You could use :visible to see if the dropdown div for the autocomplete is open, and then prevent the enter key action of your code completing. Something like this:
$("form input").keypress(function(e) {
var key = e.which || e.keyCode;
if (key == 13 && !$(".autocomplete").is(":visible")) {
e.preventDefault();
$('form').submit();
}
});
You could also use event.stopPropagation() on the enter key press in the autocomplete function, however you'll probably have to amend the source manually which isn't ideal.
Before return false;
write
e.preventDefault();
or/and
e.stopPropagation();
$("form input").keypress(function (e) {
if (e.target.id !== "autoCompliteId" && ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13))) {
$('button[type=submit].default').click();
return false;
} else {
return true;
}
});
I modified my code and it works now.
I have an enum called Operation in my command and I set different value of the field before every submit button eg:
<input type="submit" value="do sth" onclick="setOperationAndSubmit('DO_STH')"/>
<input type="submit" value="next" onclick="setOperationAndSubmit('DEFAULT')"/>
function setOperationAndSubmit(operation) {
if (document.myForm.elements['operation'].value === '') {
document.myForm.elements['operation'].value = operation;
}
document.myForm.submit();
}
Then I have my action that listens to keypress and it set appropriate operation on every enter key:
$(function() {
$("form input").keypress(function(e) {
if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
document.myForm.elements['operation'].value = 'DEFAULT';
}
});
});
so default action is executed when I press enter

How can I disable the ENTER key on my textarea?

<form name='qform'>
<textarea name='q' rows='3' cols='60' wrap='hard' id='q' onkeydown="if (event.keyCode == 13) document.getElementById('clickit').click()"></textarea>
<input type='button' value='search' id='clickit' onclick="get();">
</form>
I have this form... it doesn't have a submit button because I am using jquery and under this form is a div area where the results will be shown. It is a search engine that does not have an input box but instead has a textarea. This is because it will be a multiple word searcher.
The problem is that if I press enter, the query is submitted and everything is ok ... but the focus on textarea goes down one line and that is a problem for me.
Basically I want the enter to have that one function only(submit) end nothing else.
$(document).ready(function() {
$('textarea').keypress(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
}
});
});
Why not just use <input type="text"> if you don't want multiple lines? You mentioned it will be a "multiple word searcher". Why does this require a <textarea>?
Update
Try this
$('textarea').bind('keypress', function(e) {
if ((e.keyCode || e.which) == 13) {
$(this).parents('form').submit();
return false;
}
});
In the jquery function, use event.preventdefault and next do what you like.
For example
<script>
$("a").click(function(event) {
event.preventDefault();
//Do your logic here
});
</script>
http://api.jquery.com/event.preventDefault/
Pure javascript:
document.addEventListener('keypress', function (e) {
if (e.keyCode === 13 || e.which === 13) {
e.preventDefault();
return false;
}
})

Prevent form submission on Enter key press

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
})
Mozilla Docs
Supported Browsers
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');
}
});
http://jsfiddle.net/umerqureshi/dcjsa08n/3/
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 = (() => {
alert('ok');
let keyListener = document.querySelector('#searchUser');
//
keyListener.addEventListener('keypress', (e) => {
if(e.keyCode === 13){
let username = e.target.value;
console.log(`username = ${username}`);
fetch(`https://api.github.com/users/${username}`,{
data: {
client_id: 'xxx',
client_secret: 'xxx'
}
})
.then((user)=>{
console.log(`user = ${user}`);
});
fetch(`https://api.github.com/users/${username}/repos`,{

}
})
.then((repos)=>{
console.log(`repos = ${repos}`);
for (let i = 0; i < repos.length; i++) {
console.log(`repos ${i} = ${repos[i]}`);
}
});
}else{
console.log(`e.keyCode = ${e.keyCode}`);
}
});
})();
<input _ngcontent-inf-0="" class="form-control" id="searchUser" placeholder="Github username..." type="text">

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
}
});

Submitting a form on 'Enter' with jQuery?

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.
Tested on IE11 and FF61 on Server 2012 R2
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();
}
})
}
