synchronization objects and / or devices

greetings.

I want to know if there is any way that two objects are synchronized, ie if I move an object on a page also moves in the other but apart from that can be done with two different devices, ie two different laptop or what whether you connect to the site.

I do not know if I would help explain a lot but your answers, ideas and comments

thanks

One idea is to use AJAX to both send and recieve data with a server and then let the game synch to that server.

thank you very much for your response, I used a lot now going to get me to learn some ajax

looks and been reading a bit more and I found socket.io have any idea as used in this and whether I can do what I have as a purpose. I can also see that with javascript
