Simulating Key Press Events Programmatically in JavaScript

Question:

Is it feasible to simulate key press events programmatically in JavaScript?

Answer:

Non-jQuery Solution Compatible with Webkit and Gecko:

To simulate key press events without using jQuery, you can leverage the following cross-compatible solution:

var keyboardEvent = document.createEvent('KeyboardEvent');
var initMethod = typeof keyboardEvent.initKeyboardEvent !== 'undefined' ? 'initKeyboardEvent' : 'initKeyEvent';
    
keyboardEvent[initMethod](
  'keydown', // event type: keydown, keyup, keypress
  true, // bubbles
  true, // cancelable
  window, // view: should be window
  false, // ctrlKey
  false, // altKey
  false, // shiftKey
  false, // metaKey
  40, // keyCode: unsigned long - the virtual key code, else 0
  0, // charCode: unsigned long - the Unicode character associated with the depressed key, else 0
);
document.dispatchEvent(keyboardEvent);
