How to disable Windows keys (logo key and menu key) using Javascript

Question

I write this Javascript code but it doesn\'t disable 2 windows keys (I mean logo key and menu key), though:

document.onkeydown = function(e) {
    document.t         


        

Answer 1

Your code looks right, try to find out real keycodes with this simple script:

document.onkeydown = checkKeycode
function checkKeycode(e) {
  var keycode;
  if (window.event) keycode = window.event.keyCode;
  else if (e) keycode = e.which;
  alert("keycode: " + keycode);
}

And to disabel certain keys you modify function (example for 'Enter'):

document.onkeydown = checkKeycode
function checkKeycode(e) {
  var event = e || window.event;
  var keycode = event.which || event.keyCode;

  if (keycode == 13) {
    // return key was pressed
  }
}
