Session.js

Gives information about the current session.

To use: include the file session.js, then access the visitor object. It uses the google javascript loader to get location data. For async loading, use the window.session_loaded callback.

Live Demo

To add more fields, add or remove included modules and options near the bottom of the js file.

Usage:

Include session.js in the head or footer.

If used in the footer (before the </body> tag), you can use the window.session_loaded = function(session){} callback).

Options:

Set window.session_opts before including session.js to change options. Default options are shown below.

window.session_opts = {
  use_html5_location: false,
  // use html5 location -- this _ONLY_ return lat/long, not an city/address
  ipinfodb_key: null,
  // attempts to use ipinfodb if provided a valid key -- get a key at http://ipinfodb.com/register.php
  gapi_location: true,
  // leaving true allows for fallback for both the html5 location and the ipinfodb
  session_days: 32,
  // how many days session information is kept in a cookie
  location_cookie_name: 'location',
  // the name of the location cookie
  //   -- warning: different providers use the same cookie
  //   -- if switching providers, remember to use another cookie or provide checks for old cookies
  session_cookie_name: 'first_session',
  // session cookie name
  location_cookie_hours: 2
  // lifetime of the location cookie
};
