Send List Data

Send List Data

Hi,
I´m making and app that the user is adding element and I show is to the user in a Main View with a List (as a shopping cart) and I want to know the way to send it to the server.
My first idea is a button binded to a JS Function that will access to the dom, search for all li items, get the data, send to the server and if it is successfull, them navigate to other action.

Is there any more simple for doing this?

Thanks
