how to use javascript map variable in servlet

[santaji]

I want to keep mapping of some key value pairs in javascript for that i m using a map inside javascript and want to access this map at server side in servlet where I don't know the key and value so I want to know is there anything can be done to access this var in servlet like java map where i can get both keys and corresponding values also.

var output={}

output[id1] = value1;
output[id2] = value2;
output[id3] = value3;

how can I access these stored values inside servlet?

you would need to transfer that to the server with an ajax-call or whatever request ... just create a json-string from it or xml or plain text or what you prefer and add it to a request that your servlet could handle ...

kind regards
