Capture keyDown for current page only

I have forms on different pages of my applications. Upon pressing 'Enter' or 'Esc', the form on the current page must be 'Submitted' or 'Cancelled'. The keydown() function should be triggered anywhere on the page and not tied to a specific DOM element.
.js
$(document).keydown(function(e) {
if(e.which == 13) {
// enter pressed
$('#submitCreateAccountForm').click();
$('#submitForm').click();
$('#submitNewSubmissionForm').click();
}
if(e.which == 27) {
// esc pressed
$('#submitCreateAccountFormCancel').click();
$('#submitFormCancel').click();
$('#submitNewSubmissionFormCancel').click();
}
});
What should 'document' be replaced by? Thanks

try this
$(function(){
$('html').bind('keypress', function (e) {
if (e.keyCode == 13) {
//do somethings
}
else if (e.keyCode == 27) {
return false;
}
});
});

You can try this code:
$("body").keyup(function(event){ // bind keyup event to body
if(event.keyCode == 13){ // 13 - code of enter key (find for ESC)
$("#enter").click(); // bind enter press for clicking botton with id="enter" and corresponding actions
}
});

esc key event for jquery dialog

Have jquery dialog as closeOnescape as false. want to trigger an event based on esc key press how do i achieve it?
this on also not working
$(document).on("keypress","#popupid",function(e) {
debugger;
if (e.keycode === 27) {
alert("esc key triggered");
}
});

Replace keypress by keyup function
$(document).on('keyup', function(e) {
if (e.keyCode === 27) { // escape key maps to keycode `27`
alert("esc key triggered");
}
});
Explanations :
Here

$(document).keypress(function(e) {
if (e.keyCode==27){
//do smth
}});

Why does keyup doesn't return false while keydown do? [duplicate]

I have the following code:
$(document).on('keyup', 'p[contenteditable="true"]', function(e) {
if(e.which == 13) {
e.preventDefault();
$(this).after('<p contenteditable = "true"></p>');
$(this).next('p').focus();
} else if((e.which == 8 || e.which == 46) && $(this).text() == "") {
e.preventDefault();
alert("Should remove element.");
$(this).remove();
$(this).previous('p').focus();
};
});
I would like to prevent the default action when a key is pressed. preventDefault works for keypress but not keyup. Is there a way to prevent the defualt for $(document).on('keyup')?

No. keyup fires after the default action.
keydown and keypress are where you can prevent the default.
If those aren't stopped, then the default happens and keyup is fired.

We can prevent the action by using following code snippet.
e.stopPropagation();
e.preventDefault();
e.returnValue = false;
e.cancelBubble = true;
return false;
keyup fires after keydown/keypress. we can prevent default action in anyone of those events.

javascript avoid enter key press

I'm trying to detect an Enter key press event when a button has been clicked.
I'm new in javascript and don't know the good way to go...
HTML:
<div id="div"> Only execute javascript on click, not enter key press </div>
JAVASCRIPT:
$("#div").click(function () {
/* IF ENTER KEY PRESSED, RETURN FALSE */
$("#div").keypress(
function(event){
if (event.which == '13') {
event.preventDefault();
alert('clicked');
}
});
/* Div has been clicked, continue code... */
});
This doesn't work...
Maybe there is a better way:
$("#div").MOUSE_CLICK_EVENT(function () {});

You need to stopPropagation like:
$('#div').keydown(function(event){
if (event.which == '13') {
event.preventDefault();
event.stopPropagation();
}
});
stopPropagation: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.

As others have noted, you need stopPropagation in addition to preventDefault, and you should be listening for the keydown event rather than keypress.
The pure JavaScript way to do this is:
document.getElementById('div').onkeydown = function (evt) {
if (evt.which === 13) {
evt.preventDefault();
evt.stopPropagation();
return false;
}
};
document.getElementById('div').onclick = function (evt) {
// do whatever you want here
};

try this if still needs anybody. Quick solution.
$("form").keypress(function(e) {
//Enter key
if (e.which == 13) {
return false;
}
});

Also you need to consider 3 key events: keydown, keypress and keyup.
$("#ID").keydown (function (e) {
if ( e.key == 'Enter') {
e.preventDefault();
e.stopPropagation();
return false;
}
});
$("#ID").keyup (function (e) {
if (e.key == 'Enter') {
e.preventDefault();
e.stopPropagation();
return false;
}
});
$("#ID").keypress (function (e) {
if (e.key == 'Enter') {
e.preventDefault();
e.stopPropagation();
return false;
}
});

How to simulate tab key with enter key on javascript

<script type="text/javascript">
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
if (event.keyCode == 13) {
event.keycode=9;
return event.keycode;
}
});
});
}
</script>
here i'm using above script to fire tab key press event when i press the enter key.but it doesn't behave as tab key pressed when i press the enter key.
please help me here..

return event.keycode is effectively return 9, and even return event will not help, as returning the event does not mean that will be handled properly, what you probably want to do instead is to take the enter event and then manually change focus to the next required field:
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
event.preventDefault();
if (event.keyCode == 13) {
$(this).next("input, textarea").focus()
}
});
});
}

It will not simulate until you prevent the default enter key event.
event.preventDefault(); should be the first command of your function.Then implement the tab key event.Your code should be something like this :
<script type="text/javascript">
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
event.preventDefault();
if (event.keyCode == 13) {
event.keycode=9;
return event.keycode;
}
});
});
}
</script>
Hope it will work.
