Middle click a dropdown menu

Question

I'm trying to make a dropdown menu that opens something in a new tab if you middle click. The problem is that middle click doesn't seem to trigger the onclick event.

Edit: I haven't learned JQuery, and I would prefer a method that doesn't require it.

Check out my example:

$(document).bind('mousedown', function(e) { 
   if( (e.which == 1) ) {
     alert("left button");
   }if( (e.which == 3) ) {
     alert("right button");
   }else if( (e.which == 2) ) {
      alert("middle button"); 
   }
   e.preventDefault();
}).bind('contextmenu', function(e){
 e.preventDefault();
});
