Jquery: Enter to blur - javascript

Please check out this fiddle: http://jsfiddle.net/7wp9rs2s/ this is how far I have come with this project.
Basically, in the above fiddle you can double click on one of the 4 items and when you do, you get a textbox where you can edit it. Then you click out and it goes back to being a text. Most users wont click out but will instead press enter (like SO's comment function) so if the user presses enter, while making the edit, I want the script to react in the same way as if the user clicked out of the box.
I know how to capture the Enter key:
$(document).keypress(function(e) {
if(e.which == 13) {
alert("in Enter");
}
});
But I do not know how to make the function do what I need :(

Your functions are called on blur, so simply trigger a blur on the input :
$(document).keypress(function(e) {
if(e.which == 13) {
$(e.target).blur();
}
});

Manually triggering jquery keyup event passing wrong keycode

I have an input that I want to allow the user to save the text either by pressing enter or by clicking anywhere else on the screen. Getting the code to process when the user presses enter is no problem. But I want to process the same code by triggering the jquery keyup event when the user clicks away just as if they pressed Enter on the input box instead. The theory isn't giving me an issue, but the keycode is either not being passed correctly or interpreted correctly when clicking away. When I alert the interpreted keycode, I get a "1" which doesn't equate to any keypress. What am I doing wrong?
$(document).on("click","body",function(e){
if(e.target.id!="openInput"){ //Indicates user has clicked out away from the input
if($(".attributeEdit")[0]){ //This is a unique class added
var i = $.Event('keyup');
i.which = 13;
$(".attributeEdit").trigger(i); //Have also tried triggering off #openInput, too with no success
}
}
});
$(document).on("keyup",".attributeEdit",function(){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == '13'){
do stuff;
}
else{
alert("keycode: " + keycode); //This results in a "1" every time user clicks away
}
});
I found a solution to the end objective using Hiren Raiyani's suggestion of a function call. It doesn't actually answer the original question, but since it solved my problem, I'm hoping this will be useful to others that search. I created a function to "do stuff" and that way, I can call that function both after the Enter key is pressed and after the mouse is clicked.
function doStuff(x,y){
do stuff
}
$(document).on("click","body",function(e){
if(e.target.id!="openInput"){ //Indicates user has clicked out away from the input
if($(".attributeEdit")[0]){ //This is a unique class added
doStuff(x,y);
}
}
});
$(document).on("keyup",".attributeEdit",function(){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == '13'){
doStuff(x,y);
}
});

Count the number of times enter is pressed in a webpage

Is there really a way with which i could count the number of times, the enter key is pressed in a webpage. Not within an element say, a text box for an example, but rather the whole webpage. say if i open google.com and type something in the search box and hit enter, so the count is one. as such, another search would give 2 enters pressed.any suggestions or ideas?
You can achieve this by using following approach:
var noOfCounts = 0;
$(document).on('keyup', function(e){
if (e.which == 13){
noOfCounts ++;
}
});
You want a JS event listener
MDN Docs
Specifically keydown.
window.addEventListener('keydown', function(e){
console.log(e.keycode);
});
Then figure out which keycode you need and run your validation and other functions from there.

How to prevent moving to next page on clicking enter key using javascript in html?

I'am having the following code in javascript in order to navigate from textboxes and textareas. The issue is the functionality is working fine but, when clicking on enter it is navigating to next textbox, at the same time it is navigating to next page, how to prevent to navigate to next page when clicking on enter key. Can someone help me thanks.
$('input[type="text"],textarea').keyup(function(e){
if(e.which==39 || e.which==13)
$(this).closest('td').next().find('input[type="text"],textarea').focus();
else if(e.which==37 || e.which==8)
$(this).closest('td').prev().find('input[type="text"],textarea').focus();
else if(e.which==40 || e.which==13)
$(this).closest('tr').next().find('td:eq('+$(this).closest('td').index()+')').find('input[type="text"],textarea').focus();
else if(e.which==38 || e.which==8)
$(this).closest('tr').prev().find('td:eq('+$(this).closest('td').index()+')').find('input[type="text"],textarea').focus();
});
On keyDown for your text input, catch the input if it's the enter key and prevent the default behavior:
$('input[type="text"],textarea').keydown(function () {
if(event.keyCode == 13){
event.preventDefault();
}
});
If I recall correctly, keyDown is necessary to prevent the default enter action, rather than keyUp. But give both a try and see which works.

Unfocusing textbox with jQuery when key pressed

I have a textbox that displays an alert when you click outside the textbox. I'm trying to also display the alert if the user presses Enter. Here's what I have:
<input id="txtInput" type="text" onblur="alert('Hello');" />
<script type="text/javascript">
$(document).ready(function () {
$("#txtInput").keyup(function (event) {
if (event.keyCode == 13) {
$(this).blur();
return false;
}
});
});
If I click inside the textbox and then click outside it, the alert shows correctly.
But if I'm inside the textbox and push Enter, it shows the alert - when I dismiss the alert, another alert shows (I assume because onblur is being called on the textbox).
Why doesn't calling $(this).blur() remove the focus from the textbox? Or is there a better way to do this?
Why this works, I can't tell you, but if you remove the onblur event from your HTML and put it into your js, it works.
http://jsfiddle.net/ERdaa/4/
$("#txtInput").keyup(function (event) {
if (event.keyCode == 13) {
$(this).blur();
return false;
}
}).blur(function(){
alert('Hello');
});
[edit] cleaned up code to use chaining instead of using selector twice.

Prevent Enter key works as mouse click

I noticed that if you focus on an element that mouse clic can be triggered, the Enter keys acts like as you left click the mouse. I want to avoid this running since it comes into conflict in other pieces of my code.
In the following example if I focus on this imageButton and I clic once, the next clicks can be "done" with the Enter key, so I don't want this because this button fires a slideToggle() and shows a hidden div, so IMO it's pointless toggle this div with the keyboard.
Is there any way to make it global way?
Thank you.
Try this:
$(".myElements").keypress(function(e) {
if (e.which == 13) {
e.preventDefault();
}
});
It will stop the enter key behaviour only, allowing the other key functions to work as usual.
Listen for "keypress" and .preventDefault()
ex. with <myelm class="nokey"/>
function noKeyPressing(){
var elms = document.getElementsByClassName('nokey'),
stop = function stop(e){ return e.preventDefault(), false; },
i = elms.length;
while(--i >= 0){
elms[i].addEventListener('keypress', stop, true);
}
}
noKeyPressing()
If you just want to prevent Enter then the keyCode to look for is 13.
try
.unbind('keydown');
to disable all key events on your element
You can return false to prevent the default action.
<input type="submit" onkeypress="return false;" value="Submit" />
An other possible way i think:
$('.elems').on('click',function(){$(this).blur()});
try this code
$('body *').keypress(function (e) {
if (e.which == 13) {
e.preventDefault();
}
});
the above code will prevent pressing enter for every element in page
,You can change the selector $('body *') to something else depending to your case
