Jquery: detect if middle or right mouse button is clicked, if so, do this:

You may want to trap the mousedown event, and you also need to prevent the oncontextmenu event to stop the context menu from coming up during the right click event.

$("h2").live('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();
}).live('contextmenu', function(e){
   e.preventDefault();
});

UPDATE: .live() has been deprecated since jQuery 1.9. Use .on() instead.

$("h2").on('mousedown', function(e) { 
  if (e.which == 1) {
    alert("left button");
  } else if (e.which == 3) {
    alert("right button");
  } else if (e.which == 2) {
    alert("middle button");
  }
  e.preventDefault();
});
