prevent Save dialog to appear on Ctrl S

I want to save page changes when Ctrl-S or Ctrl-Enter is pressed
Ctrl-Enter works fine but on Ctrl-S I cannot prevent a Save dialog to appear.
$(document).on('keydown', function(e){
if (e.ctrlKey && (e.keyCode == 13 || e.keyCOde == 83)){
e.preventDefault();
// save data...
}
});
Any help?

Typo in your code
e.keyCOde == 83 ===> e.keyCode == 83 [Character "O" should be small]

This is what I use :
$(document).keydown(function(event) {
if (!((String.fromCharCode(event.which).toLowerCase() == 's' || event.keyCode == 13) && event.ctrlKey) && !(event.which == 19)) return true;
alert("Ctrl-S pressed");
event.preventDefault();
return false;
});
Another choice is that you can use Shortcut library, you can enjoy more shortcut keys than just ctrl+s. Plus, this library has short & handy code as well :
shortcut.add("Ctrl+S",function() {
alert("Hi there!");
});

Capture the event click of "Open Link in New Tab" javascript or jquery - Cloaking URL

I know that I can capture the events of click: left, right and middle button by:
contextmenu
e.which
But, I need to capture the event click of "Open Link in New Tab":
When you do right click in a link, it shows a menu with the option "Open Link in New Tab".
How can I capture that event ?
PD: is not the right click event, is the event when you do click in "Open Link in New Tab".
The main reason is, I'm trying to cloak links for affiliated sites, but when I do right click and choose the option "Open Link in New Tab", not working, it doesn't show me the real hidden url.
I found the script searching in google but I edited the script to my needs, but I have the problem that I told above.
The code:
(function ($) {
ninja_href(".ninja-href");
function ninja_href_call(e,which)
{
var ninja_url = e.target.getAttribute('data-ninja-url');
var ninja_target = e.target.getAttribute('data-ninja-target');
if(ninja_target == null || typeof ninja_target == undefined || which === 3)
{
ninja_target = "_self";
}
if(which === 2)
{
ninja_target = "_blank";
}
var win = window.open(ninja_url, ninja_target);
if (win && ninja_target == "_blank")
{
win.focus();
}
}
function ninja_href(element)
{
if(element == null || typeof element == undefined){
element = ".ninja-href";
}
if (document.addEventListener)
{
document.addEventListener('click', function(e) {
if(e.target && e.target.matches(element))
{
if (e.which === 1 || e.which === 2)
{
e.preventDefault();
ninja_href_call(e,e.which);
}
}
}, false);
document.addEventListener('mousedown', function(e) {
if(e.target && e.target.matches(element))
{
if (e.which === 2)
{
e.preventDefault();
ninja_href_call(e,e.which);
}
}
}, false);
document.addEventListener('contextmenu', function(e) {
console.warn(e);
if(e.target && e.target.matches(element))
{
}
}, false);
} else {
document.attachEvent('click', function() {
if(e.target && e.target.matches(element))
{
if (e.which === 1 || e.which === 2)
{
e.preventDefault();
ninja_href_call(e,e.which);
}
}
});
}
}
}(window.jQuery));
Any idea

Please take a look below... This is how you can handle it.
<script type='text/javascript'>
jQuery(function($){
$('a').mousedown(function(event) {
switch (event.which) {
case 1:
//alert('Left mouse button pressed');
$(this).attr('target','_self');
break;
case 2:
//alert('Middle mouse button pressed');
$(this).attr('target','_blank');
break;
case 3:
//alert('Right mouse button pressed');
$(this).attr('target','_blank');
break;
default:
//alert('You have a strange mouse');
$(this).attr('target','_self"');
}
});
});

How to disable View source and inspect element

How do you disable/ view source/ and /inspect element/, ctrl + u ctrl+shift+I f12 menu bar and right click, also ctrl + s ctrl p ctrl+v ctrl+a ctrl+c and drag select page, please answer all parts that's possible, I prefer to do this will JavaScript array keycodes or html no php or other languages.also I want to block ifram use on my site like somesites such as google.
As I understand it is not possible to completely disable view source and inspect element, so I want minification of code and rest of my question answered instead.
Edit:
I solved alot of it myself, I used onkeydown return false to disable all keys, still need the arrays, I disabled inspect element menu bar by forcing browser to window.open I still need right click, however would like to add that I need a custom right click menu, I disabled the possibility to disable Javascript in order to stop the key block by using noscript function redirects. I also still need the drag and select part. I would still like betterways to fix it...maybe even just minify the code or encrypt it. Of anyone needs some of the code I used just reply. I just need to fix it.

It is not possible to prevent the user from inspecting code running on their machine. At the end of the day the HTMl they are getting delivered will be readable in plain text. You can cause a nuisance for most people, but this will not be a valid security measure - chrome extensions will still run, for instance, so if someone is using the NoScript extension it will disable all javascript.
A much better option would be to handle your logic serverside, and only send the client the information they need to know/requested.
There are some free javascript obfuscators, such as https://javascriptobfuscator.com/. Please remember that it is not a secure method, though.

I mean no matter how much you block it a person can just type
view-source:https://example.com

document.onkeydown = function(e)
{
if(event.keyCode == 123)
{
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0))
{
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0))
{
return false;
}
if(e.ctrlKey && e.keyCode == 'U'.charCodeAt(0))
{
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'C'.charCodeAt(0))
{
return false;
}
}
e is a keyboard event. e.[key] returnes true if key pressed.
If document.onkeydown returns false, key doesn't count.
This programm seeing if code view combination pressed and returning false.
Example. if ctrl, shift and 'J' pressed - return false.

Bump
To the people saying it isn't possible, how would you recon this website managed to do so?
The following website disabled, view source, right click and the dev console.
I am genuinely interested.
https://www.techgyd.com/contact-facebook-directly/6579/
Edit:
all input from keyboard is disabled, but by adding "view-source:" before the httpps:// to the url to become:
view-source:https://www.techgyd.com/contact-facebook-directly/6579/
makes me able to see.
If you would like to know how they did that then take a look at their JS, raw copy/paste:
<script type="text/javascript">
//<![CDATA[
var show_msg = '';
if (show_msg !== '0') {
var options = {view_src: "View Source is disabled!", inspect_elem: "Inspect Element is disabled!", right_click: "Right click is disabled!", copy_cut_paste_content: "Cut/Copy/Paste is disabled!", image_drop: "Image Drag-n-Drop is disabled!" }
} else {
var options = '';
}
function nocontextmenu(e) { return false; }
document.oncontextmenu = nocontextmenu;
document.ondragstart = function() { return false;}
document.onmousedown = function (event) {
event = (event || window.event);
if (event.keyCode === 123) {
if (show_msg !== '0') {show_toast('inspect_elem');}
return false;
}
}
document.onkeydown = function (event) {
event = (event || window.event);
//alert(event.keyCode); return false;
if (event.keyCode === 123 ||
event.ctrlKey && event.shiftKey && event.keyCode === 73 ||
event.ctrlKey && event.shiftKey && event.keyCode === 75) {
if (show_msg !== '0') {show_toast('inspect_elem');}
return false;
}
if (event.ctrlKey && event.keyCode === 85) {
if (show_msg !== '0') {show_toast('view_src');}
return false;
}
}
function addMultiEventListener(element, eventNames, listener) {
var events = eventNames.split(' ');
for (var i = 0, iLen = events.length; i < iLen; i++) {
element.addEventListener(events[i], function (e) {
e.preventDefault();
if (show_msg !== '0') {
show_toast(listener);
}
});
}
}
addMultiEventListener(document, 'contextmenu', 'right_click');
addMultiEventListener(document, 'cut copy paste print', 'copy_cut_paste_content');
addMultiEventListener(document, 'drag drop', 'image_drop');
function show_toast(text) {
var x = document.getElementById("amm_drcfw_toast_msg");
x.innerHTML = eval('options.' + text);
x.className = "show";
setTimeout(function () {
x.className = x.className.replace("show", "")
}, 3000);
}
//]]>

I hope it helps

prevent default 'F1' event in iE11

When the user press F1 key,I am planning to display our application help and suppress default action.
I tried with different options not to show help popup of IE.
Here is my Code:
document.addEventListener('keydown', function (e) {
if (e.key === 'F1' || e.keyCode == 112) {
e.cancelBubble = true;
e.cancelable = true;
e.stopPropagation();
e.preventDefault();
e.returnValue = false;
//my help menu code goes here
}
});
Please let me know how can i achieve in showing the help page of my application instead of IE help.
I am using IE11 version.

You could subscribe to the window.onhelp event:
window.onhelp =function() {
alert();
return false;
}

Try doing this
<script>
$(document).ready(function () {
removedefaulthelp();
function removedefaulthelp()
{
window.onhelp = function () {
return false;
alert();
}
}
document.addEventListener('keydown', function (e) {
if (e.key === 'F1' || e.keyCode == 112) {
removedefaulthelp();
e.cancelBubble = true;
e.cancelable = true;
e.stopPropagation();
e.preventDefault();
e.returnValue = false;
//my help menu code goes here
}
});
}
</script>
Refer this for more information.

Here is an example similar to Sukanya's answer, but my solution shows how to extend for the F2-F12 keys, and purposely disregards F-combination keys, such a CTRL + F1.
<html>
<head>
<!-- Note: reference your own JQuery library here -->
<script type="text/javascript" src="jquery-1.6.2.min.js"></script>
</head>
<body>
<h1>F-key trap example</h1>
<div><h2>Example: Press the 'F1' key to open help</h2></div>
<script type="text/javascript">
//uncomment to prevent on startup
//removeDefaultFunction();
/** Prevents the default function such as the help pop-up **/
function removeDefaultFunction()
{
window.onhelp = function () { return false; }
}
/** use keydown event and trap only the F-key,
but not combinations with SHIFT/CTRL/ALT **/
$(window).bind('keydown', function(e) {
//This is the F1 key code, but NOT with SHIFT/CTRL/ALT
var keyCode = e.keyCode || e.which;
if((keyCode == 112 || e.key == 'F1') &&
!(event.altKey ||event.ctrlKey || event.shiftKey || event.metaKey))
{
// prevent code starts here:
removeDefaultFunction();
e.cancelable = true;
e.stopPropagation();
e.preventDefault();
e.returnValue = false;
// Open help window here instead of alert
alert('F1 Help key opened, ' + keyCode);
}
// Add other F-keys here:
else if((keyCode == 113 || e.key == 'F2') &&
!(event.altKey ||event.ctrlKey || event.shiftKey || event.metaKey))
{
// prevent code starts here:
removeDefaultFunction();
e.cancelable = true;
e.stopPropagation();
e.preventDefault();
e.returnValue = false;
// Do something else for F2
alert('F2 key opened, ' + keyCode);
}
});
</script>
</body>
</html>

jQuery Crashes on .live("keyup")

I have some code here:
$(document).ready(function() {
$("#querybox").live("keyup", function(e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 13) {
$("#querybox").blur();
}
else {
search(document.getElementById('querybox').value);
}
/*if (document.getElementById('querybox').value == "") {
$("center").removeHighlight();
}*/
});
});
that detects a keyUp and uses it to search something. The problem is: when the #querybox is backspaced to the point where it is empty, the entire page crashes and I get the "Awwww, Snap!" message from Google Chrome.
I am using jQuery v1.7.2
Thx a million!
EDIT
I should also point out that the search() function highlights text in the body (notice the commented section). I am using the highlight plugin...
Search Fn:
function search(query) {
$("center").removeHighlight();
$(".paragraph").highlight(query);
$(".highlight").each(function (index) {
$(this).attr("id", "tmpforgoToByClassScrollhighlight" + index);
});
}

Try using .on(...) instead:
$("#querybox").on("keyup", function(e) {
var code = (e.keyCode ? e.keyCode : e.which);
var queryBox = this;
if (code === 13) { // PRESSED ENTER
queryBox.blur();
}
else {
search(queryBox.val());
}
});
After your update:
You might want to look better into how you do your search functiom.
Cache some of those jQuery elements so you do not keep selecting them over and over on each keyup.
Also, I am not going through all of the .highlight code, but there probably is a bug in there that does not allow for an empty string, and that is why the website is causing the browser to crash.

You should use .delegate() instead
$(document).ready(function() {
//It will be a good advice to replace body with a parent element of #querybox
$("body").delegate("#querybox","keyup", function(e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 13) {
$("#querybox").blur();
}
else {
search(document.getElementById('querybox').value);
}
/*if (document.getElementById('querybox').value == "") {
$("center").removeHighlight();
}*/
});
});
