Javascript

I'm at a loss, I've got 4 buttons on my game: north, south, east and west. They are <input type="button"..... You can click them and they work. How do I use javascript to trigger the same function when I press the arrow keys. I'm using jquery if that helps/hinders. I was originally just going to use the 'accesskey' attribute but had various problems doing that...

It depends how you're doing it. I assume you're using jQuery to bind "click" events on the buttons to call a named function (perhaps $(".east").bind("click", move("east")) or something to that effect?)

You could do something like:

$("body").bind('keydown', function(e){
    triggerKeydown(e);
});

var triggerKeydown = function(e){
switch(e.keyCode){
  case 38:
    move("north");
    break;
  case 40:
    move("south");
    break;
  case 37:
    move("east");
    break;
  case 39:
    move("west");
    break;
}

}

Thanks, I'll have to wait until Sunday to look at this properly

Shouldn't east and west be reversed ?
