fusion table insert or update from javascript

My purpose is to plot data from fusiontable into google map using FusionTablesLayer and to insert or update the fusion table with user created information from map. I am not ab开发者_运维问答le to locate how can I do that from javascript. Is not it possible ?

In case I can not insert or update a fusion table using javascript, what are the other alternatives available ?

I was going through CouchDB with node.js and this appears to be a good alternative. Any expert advise is most welcome.

Fusion tables have an API

Since authentication is required for inserts and updates to Fusion Tables, it's not super easy to do this through JavaScript alone. It might be possible using a JavaScript OAuth library. I haven't tested this approach, but in theory it could work.
