javascript keypress multiple records problems

I would like to ask why it will have multiple response? How can i enter the input field with just one response?
Expectation : Input the data in input field and press the enter , it will execute the actions.
$("#textInput").keypress(function (e) {
console.log("123");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<input type='text' id='textInput'/>

You have syntax error in you code. closing should be }); instead of )};
$("#textInput").keypress(function (e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="textInput">

Expectation : Input the data in input field and press the enter , it will execute the actions.
In order to submit the corresponding form as soon as the user enters a text string and a final enter key you can:
test if current char is the enter key (e.which == 13)
get the closest form
submit the form
$("#textInput").on('keypress', function (e) {
if (e.which == 13) {
$(this).closest('form').submit();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/action_page.php">
Enter text and type enter to submit:<br>
<input type="text" name="textInput" value="">
</form>

I think, you should have choose other event,like onblur to fix your problem
$("#textInput").on('blur',function (e) {
console.log("123");
)};
In your code ,keypress events gives you output,in every keypress action,So this is the reason you got multiple responses
And next,if you think,if you want to press Enter button then need response,In this case little changes will helps you
$("#textInput").keypress(function (e) {
if(e.which == 13) {
console.log("123");
}
});

The keypress event is sent to an element when the browser registers keyboard input.
— jQuery Documentation link
What you really want is .submit() as they are the one that will only be triggered when the user submits info.
$("#textInput").submit(function (e) {
console.log("123");
)};
Or if you only want to detect enter keypress but not submit, use this:

jquery - add event handler on event that takes another event as argument

I am trying to call a function scheduleAdd when the enter button is hit, but I only want it to work if an input with the id 'addSchedule' is in focus. Here's what I have:
$('#addSchedule').focus(function(e) {
var evt = e || window.event;
if(evt.keyCode == 13) {scheduleAdd};
});
I know the code inside the .focus works, because I tried it on its own and it triggers the function scheduleAdd when the enter key is hit. How can I make this conditional on 'addSchedule' being in focus?
Also, more generally, I was wondering if there's a standard way to ascribe event handlers conditional on a second event, such as nesting .on() or something.
Thanks.

Demo on fiddle
HTML:
<form>
<input id="addSchedule" type="text" />
</form>
Javascript:
$('#addSchedule').keydown(function (event) {
if (event.which == 13) {
event.preventDefault(); // This will prevent the page refresh.
scheduleAdd();
}
function scheduleAdd() {
alert("Add the schedule");
}
});

Simply the keydown event, and decide to do something or nothing based on whether the current element has the specified id:
$(document).on("keydown", function() {
if (!$("#addSchedule").is(":focus")) return;
// do stuff
});
Alternatively you can also check for the identity of the focused element with document.activeElement.id === "addSchedule" if you don't mind that's not enough jQuery. ;-)

Keyup event in focused input when clicked link

I have a button and when it have clicked I show some input field.
The input field tracks keyup events itself.
When I click the button using my keyboard (focus it then hit return) the input field receives an unexpected keyup event.
Demo: http://jsfiddle.net/LpXGM/3/ (just hit return and look at the messages on the page)
But if I add a timeout everything works as expected. Demo: http://jsfiddle.net/8BRmK/1/ (no keyup event when hitting return on the button)
Why does this strange thing happen? And how can I fix it?
The code with the handlers:
$button.on("click", function(){
showModal();
});
$emailField.on("keyup", function(event) {
// process the event
});
var showModal = function() {
$modal.show();
$emailField.focus();
}

Possible solution without timeOut: http://jsfiddle.net/agudulin/3axBA/
$button.on("keypress", function(event){
if (event.keyCode == 13) {
return false;
}
});
$button.on("keyup", function(event){
if (event.keyCode == 13) {
showModal();
$status.append($("<span>enter has been pressed</span></br>"));
}
});

Try $button.on("keyup mouseup", function(){
or $emailField.on("keypress", function(event) {

try
$(document).ready(function(){
$(document).on("click",".btn",function(e){
$status.append($("<span>btn click</span></br>"));
});
$(document).on("keyup",".email",function(e){
$status.append($("<span>keyup " + event.keyCode + "</span></br>"));
});
});

yes its happens because one you click the keyboard than the button click event fire first and than as per your logic your input field take focus and your keyup event is fire. but when you give Timeout so click event is fire first but because of timeout your logic is delayed and than your your keyup event done our work so the focus in not in your input that why it not enter any word in your input.

jQuery: fire keyup on all document excluding one input text field

I have a
$(document).keyup(function(e) {
//some code is here
});
code, that works as expected: it fires when I press any key on the keyboard.
I want it to fire, but not when the cursor is in the
<input type="text" id="excludeMeFromFiring">
which is on the page.
How to modify the code above to exclude firing when typing in the input text field with a special id? So it doesn't fire if the cursor is in the input text field.
Thank you.

It's easy to do that in the keyup function:
$(document).keyup(function(e) {
if ($(e.target).closest("#excludeMeFromFiring")[0]) {
return;
}
// It's not that element, handle it
});
That's the general case; because input elements can't have any elements within them, you could just use e.target.id rather than closest:
$(document).keyup(function(e) {
if (e.target.id === "excludeMeFromFiring") {
return;
}
// It's not that element, handle it
});
I use closest whenever the element can have other elements inside it.

Try
$(document).keyup(function (e) {
if(e.target.id === 'excludeMeFromFiring'){
console.log('no');
}else{
console.log('hi');
}
});
$(document).keyup(function (e) {
if(e.target.id !== 'excludeMeFromFiring'){
console.log('hi');
}
});

Another Example:
$('#excludeMeFromFiring').keyup(function(e) {
e.stopPropagation();
});

jQuery event binding with accessibility in mind - click and keypress

Just a quick question, I seem to do this a lot:
$saveBtn.bind("click keypress", function(e)
{
if (e.type != "keypress" || e.keyCode == 13)
{
// Do something...
return false;
}
});
Is there a quicker way to bind an 'action' listener to a button? I want to always ensure my buttons with event listeners fire on both clicks and the enter key...this seems like it'd be a fairly common thing to want to do but found nothing on google. Any thoughts?
Thanks.

The click event doesn't actually handle the keypress in every case, it's the button that is making the click event work. When you use a div with a tabindex attribute to make it keyboard accessible, the click handler will not trigger when you press enter.
HTML
<div id="click-only" tabindex="0">Submit click only</div>
<div id="click-and-press" tabindex="0">Submit click and press</div>​
jQuery
$("#click-only").click(function (e) {
addToBody(); // Only works on click
});
$("#click-and-press").bind("click keypress", handleClickAndPress(function (e) {
addToBody(); // Works on click and keypress
}));
function addToBody() {
$("body").append($("<p/>").text("Submitted"));
}
function handleClickAndPress(myfunc) {
return function (e) {
if (e.type != "keypress" || e.keyCode == 13) {
myfunc(e);
}
};
}
So to answer the question, I don't think there is a better way (that works in every case) other than yoda2k's solution.

By binding it with click will do the job, no need for keep press. Example

You could create a second function which handles the additional logic and pass your function as a parameter:
function handleClickAndPress(myfunc)
{
return function (e) {
if (e.type != "keypress" || e.keyCode == 13) {
myfunc(e);
}
};
}
$saveBtn.bind("click keypress", handleClickAndPress(function (e) {
// do your stuff here
}));

If it's part of a form you could just listen for the "submit" event?
