You can either:

1) Set a cookie in JS and have your rails app read the cookie. If you're using not using DB-backed sessions, this may be sufficient. You may not need to use rails' actual sessions mechanism.

2) Have your JS do an XHR request to a special controller action which will save your data to the session.

Hi Starr,

Thank u for ur nice reply.

I have done the first part what u have mentioned by using "document.cookie". I am new to XMLHttpRequest(XHR) will you please guide me a little more on this with example. I have following code written in javascript

var selObj = document.getElementById('zone');       var i;       var count = 0;       for (i=0; i<selObj.options.length; i++) {         if (selObj.options[i].selected) {             selectedArray[count] = selObj.options[i].value;             count++;         }       }       document.cookie="zone_ids=" + selectedArray.toString();        var r = document.cookie;

    I want to pass this cookie value to my account controller method say "add"

          And after passing how can I access it in the controller?

I am googleing for the same but don't find good materials. Please help me out

Thanks and Regards, Shripad
