// <![CDATA[

// Special thanks to: Kevin Reed http://www.tnetweather.com/
// Kevin was the first to decode the clientraw in PHP
// Special thanks to: Pinto http://www.joske-online.be/
// Pinto wrote the basic AJAX code for this page!
// Cheerfully borrowed from Tom at CarterLake.org and adapted by
// Ken True - Saratoga-weather.org  21-May-2006
// --- added flash-green on data update functions - Ken True  24-Nov-2006
//
// --- Version 2.00 - 13-Dec-2006 -- Ken True -repackaged AJAX function, added metric/english units
//     also included Mike Challis' counter script to display seconds since last update and error
//     handling for the fetch to fix to fix random error: NS_ERROR_NOT_AVAILABLE
//     Mike's site: http://www.carmosaic.com/weather/index.php
//     Thanks to FourOhFour on wxforum.net ( http://skigod.us/ ) for replacing all the
//     x.responseText.split(' ')[n] calls with a simple array lookup.. much better speed and
//     for his streamlined version of getUVrange.
// --- Version 2.01 - 17-Dec-2006 -- Corrected cloud height calculation
// --- Version 2.02 - 20-Dec-2006 -- added unescape to set_ajax_obs comparison for lastobs
// --- Version 2.03 - 07-Jan-2006 -- added wind m/s or km/h for metric variables
// --- Version 2.04 - 08-Jan-2006 -- use epoch time for get (thanks to johnnywx on WD forum)
//                                   so a numeric time without HTMLencoded characters is used
// --- Version 2.05a - 30-Jan-2006 -- added new 'anti-NaN' check from johnnywx to make sure full
//                                   clientraw.txt is read by looking for
//                                   '12345' at start and '!!' at end of record
// --- Version 2.06 - 24-Jun-2007 -- added '/' as delimiter for currentcond
// --- Version 2.07 - 21-Sep-2007 -- added support for dynamic thermometer.php display refresh
// --- Version 2.08 - 07-Nov-2007 -- added useMPH to force wind display in Miles-per-hour and
//                                   added optional Wind-Rose, optional new current icon display graphics
// --- Version 2.09 - 23-Dec-2007 -- added maxupdates feature, new ajax variables from K. Reed www.tnetweather.com
// --- Version 2.10 - 18-Jan-2008 -- fixed icon=34 for ra1.jpg
// --- Version 2.11 - 21-Feb-2008 -- added icon=35 for windyrain.gif/.jpg
// --- Version 2.12 - 07-Mar-2008 -- added fix for 'flashing icon/thermometer' from Jim at jcweather.us
// --- Version 2.13 - 11-Mar-2008 -- changed Wind-rose defaults to .png type (Carterlake/AJAX/PHP templates)
//
// for updates to this script, see http://saratoga-weather.org/scripts-WD-AJAX.php
// announcements of new versions will be on weather-watch.com and wxforum.net
