event.keyCode on FireFox

The event object is needed as an argument to process on Firefox.


ex1)
// Firefox
function keyCode(e)
{
    alert(e.which);
}



// IE
function KeyCode()
{
     alert(event.keyCode);
}




// cross browsing
document.onkeypress = function(e){
  var result = "";


  if (typeof(e) != "undefined")
    result = e.which;
  else
    result = event.keyCode;


  alert(result);
}




=============================





ex2)


if (window.event) {
  // IE
  var ev = window.event.keyCode;
}
else
  // Firefox, Orera etc.
  var ev = e.keyCode;
}



=============================




ex3)


function click(e) {
  if (e == null) {
    if (event.button == 2 || event.button == 3) {
      alert('Do not use the fucking right button!!');
      return false;
    }
  }
  else {
    if (e.button == 2 || e.button == 3) {
      alert('Do not use the fucking right button!');
      return false;
    }
  }
}


function keypressed(e) {
  if (e == null) {
    if (event.keyCode > 0) {
      alert('Do not use the fucking keyboard!');
    }
  }
  else {
    if (e.keyCode > 0) {
      alert('Do not use the fucking keyboard!');
    }
  }
}


document.onkeydown = function(e) {
  if (typeof(e) != "undefined")
    keypressed(e);
  else
    keypressed();
}


document.onmousedown = function(e) {
  if (typeof(e) != "undefined")
    click(e);
  else
    click();
}

Are you still using the fucking IE?

That's rubbish! You know where the rubbish should go.

Rubbish Internet Explorer.
