这个想法应该是：当用户点击你识别的某个点时，应该显示弹出窗口，不是吗？

你可以这样做：

map.events.register("click", map , function(e){
   // Look for point... (your code)

   // Point detected!

   // now we need to take the popup identified by 'popupid' identifier and show it
   for(var i=0; i<map.popups.length; i++){
      if(map.popups[i].id == myid){
         map.popups[i].show();
         break;
      }
   }
});
