Which Keycode for Escape Key with Jquery

Which keycode for escape key with jQuery

Try with the keyup event:

$(document).on('keyup', function(e) {
  if (e.key == "Enter") $('.save').click();
  if (e.key == "Escape") $('.cancel').click();
});

How to detect escape key press with pure JS or jQuery?

Note: keyCode is becoming deprecated, use key instead.

function keyPress (e) {
    if(e.key === "Escape") {
        // write your logic here.
    }
}

Code Snippet:

var msg = document.getElementById('state-msg');

document.body.addEventListener('keypress', function(e) {
  if (e.key == "Escape") {
    msg.textContent += 'Escape pressed:'
  }
});

Press ESC key <span id="state-msg"></span>

How to send Escape key using JQuery

function pressEsc() {
    $('body').trigger({
        type: 'keyup',
        which: 27 // Escape key
    });
}

$(function () {
    $('body').on('keyup', function (e) {
        alert(e.which + ' key was pressed');
    });

    // Press the escape key
    pressEsc();
});

Invoke Escape key press event by jquery

You can use $.Event() to create an Event object containing a keydown event with the keyCode of 27 (which should be Esc) like:

var esc = $.Event("keydown", { keyCode: 27 });
$("body").trigger(esc); // change body to the element where you'd like to execute the escape key press.

See this working demo and the docs at jquery.com

Also note that, as stated by Christofer, this might not be working in all browsers and environments as it might be considered shady behavior that could be used in a malicious manner - just like triggering a click event on an <a> with an external href will not happen. I successfully tested this (the Esc) in Chrome, Safari, Opera, FF & IE9 though.

Why the keyCode event for escape alone not working?

use $(document).keyup instead of $(document).keypress

the following code works fine:

$(document).keyup(function(e) 
{
  alert(e.keyCode);

  if(e.keyCode==27)
  {
      alert ("Esc key");
      hide_menu();
  }
});

Key code does not hold the ESC key

Try with keyup instead of keypress

jQuery Esc Keypress bind

#pannel
{
    position:fixed;
    width:100%;
    height:200px;
    background-color:#ddd;
}

<div id="pannel"></div>

$(document).keyup(function(e){

    if(e.keyCode === 27)
        $("#pannel").slideToggle();

});

Try that?

How to catch escape key press event inside while loop in jquery?

You need to use .setTimeout, which you can cancel with.clearTimeout once you recognise a press of the escape key. The example below works.

Let me know if you needed something else.

// Start your playLoop after document is ready$(document).ready(function() {  playLoop();});

function playLoop() {
  // Append a dot so you know it's working  $(".dots").append(".");
  // Set a new timeout to count down  playLoopCountdown = setTimeout(playLoop, 1000);
}

// Attach escape key cancel$(document).on("keyup", function(e) {
  if (e.key === "Escape") {
    // Stop playLoop    clearTimeout(playLoopCountdown);
    // Tell user the timeout has been stopped    $(".dots").append("STOPPED");
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>You need to click within this iframe for the escape keypress to be registered.</p><div class="dots"></div>
