wish helps you The spacebar inserts a ..... wait for it ....... space, so why not just add a space to the value
code :
$( "textarea" ).val(function(_, val) { return val + ' '; }).focus();
var e = $.Event("keyup", { which: 32 });

$("textarea").trigger( e );

Hope that helps First: there's a problem with your HTML. You're using the short syntax for the A -- meaning that the text isn't actually part of the A content. Many browsers don't like the short syntax for A tags anyway -- not your fault, but it's our job to be more tolerant than browsers are.
Here's the corrected version:
code :
<a tabindex="7" style="cursor: pointer;" class="button" id="saveTocAddNew" onClick="saveTdsAddNew();"><span>Save & Add Another</span></a>
function addNewKeys(event) {
    if(!event) var event = window.event; // cross-browser shenanigans
    if(event.keyCode === 32) { // this is the spacebar
        saveTdsAddNew(event);
    }
    return true; // treat all other keys normally;
}

will help you There are a few potential causes to your unresponsive behaviour:
You're waiting for the keyup event, so no matter how fast they push the spacebar, your code will only respond when they release it. Inside your event you are doing a few slow things which can also call a (tiny) delay finding elements by selector is slow, cache the results where possible In my example I avoided caching $('.chosen-search input') as I wasn't sure whether that dynamically changes. Either way, to speed it up you could still cache: var $chosenSearch = $('.chosen-search') and then later on select with: $('input', $chosenSearch) any code which executes in an event handler should return ASAP unless it intends on delaying the native behaviour (and other handlers) It's complete overkill in this case, but I've shown how you can use setTimeout() to execute your code asynchronously so that the event handler returns, and then your code executes. whilst it might not be obvious why you'd do this, imagine that your code took (say) 1.5 seconds to execute - in that case there would be a 1.5second delay before every key the user typed showed up in the input box by sticking it in a setTimeout() you ensure that no matter how long your processing takes, the key will at least react first.
code :
$(function() {

  // cache the selectors to avoid re-scanning inside the event handler
  var $inputSwitch = $('#inputSwitch');
  var $cbProduct = $('#cbProduct');
  var $barcodeIn = $('#barcodeIn');

  // Not strictly necessary, but saves the messiness of callback-in-callback
  function swapContext() {
      // SHOW CHOSEN MENU INSTEAD OF BARCODE INPUT BECAUSE WE'RE TYPING A PRODUCT NAME
      $inputSwitch.trigger("click");

      // AUTOMATICALLY OPEN THE CHOSEN MENU
      $cbProduct.trigger("chosen:open");

      // GRAB WHAT WAS ENTERED INTO THE BARCODE INPUT
      var input = $("#barcodeIn").val()+" ";

      // ENTER THE INPUT TEXT INTO THE CHOSEN SELECT MENU
      $(".chosen-search input").val(input);

      // CLEAR THE BARCODE INPUT BECAUSE WE"RE USING THE CHOSEN SELECT MENU INSTEAD
      $barcodeIn.val("");    
  }

  $("input#barcodeIn").on('keydown', function(e){
  // CHECK FOR SPACEBAR PRESS IN THE BARCODE INPUT FIELD

  if (e.keyCode == 32) {
      // Ensures we can return from the handler quickly
      setTimeout( swapContext, 0 );
      return false;
  }});  

});

I hope this helps . If I understood well this will add a space char to the textarea data when you hit the button:
code :
app.controller('dummy', function($scope) {
  $scope.spaceevent = function () {
    $scope.mydata += " ";
  };
});

<div ng-app="app" ng-controller="dummy">
  <textarea id="areadata" ng-model="mydata"></textarea>
  <button type="button" class="btn btn-danger" ng-click="spaceevent()">Add Space Bar Event</button>
</div>

it should still fix some issue The example on that question is pretty good. You don't need the focus. You just need to call the button "action" function.
Here is the solution anyway, for that same example linked above:
code :
var presscount = 0;
var sendEvery = 5000; //in milliseconds
$(document).ready(function() {
  $("#test").on("keypress", function(e) {
    if (e.which == 32) {
      presscount++;
    }
    $("#output").text("The space key was pressed " + presscount + " times");
  });
     setInterval(pressKey, sendEvery);  
});

function pressKey() {
  var e = jQuery.Event("keypress");
  e.which = 32; // # space
  $("#test").trigger(e);
}

Hope that helps Here is a plunker that demonstrates sending a keypress to an element every 750ms, but you can configure the time as appropriate
