+ Initial: June 22, 2006 - Last Revised: March 24, 2008\r
+ Wrapper function set for getting and using the responseText and / or\r
+ responseXML from a GET or POST XMLHttpRequest, which can be used to\r
+ generate dynamic content for overlib or overlib2 calls, or to modify\r
+ the content of a displayed STICKY popup dynamically.\r
+\r
+ For GET Use:\r
+ onmouseover="return OLgetAJAX(url, command, delay, css);"\r
+ onmouseout="OLclearAJAX();" (if delay > 0)\r
+ or:\r
+ onclick="OLgetAJAX(url, command, 0, css); return false;"\r
+ or:\r
+ onload="OLgetAJAX(url, command, 0, css);\r
+ \r
+ Where:\r
+ url (required)\r
+ is a quoted string, or unquoted string variable name or array entry, with\r
+ the full, relative, or partial URL for a file or a server-side script (php,\r
+ asp, or cgi, e.g. perl), and may have a query string appended (e.g.,\r
+ 'http://my.domain.com/scripts/myScript.php?foo=bar&life=grand').\r
+ And:\r
+ command (required)\r
+ is the function reference (unquoted name without parens) of a function to\r
+ be called when the server's response has been received (it could instead be\r
+ an inline function, i.e., defined within the 2nd argument, or a quoted string\r
+ for a function with parens and any args)\r
+ And:\r
+ delay (may be omitted unless css is included)\r
+ is an unquoted number indicating the number of millisecs to wait before\r
+ initiating an XMLHttpRequest GET request. It should be 0 when using onclick\r
+ or onload, but may be a modest value such as 300 for onmouseover to avoid\r
+ any chatter of requests. When used with onmouseover, include:\r
+ onmouseout="OLclearAJAX();"\r
+ to clear the request if the user does not hover for at least that long. If\r
+ the popup is not STICKY, include an nd or nd2 call, e.g.,\r
+ onmouseout="OLclearAJAX(); nd();"\r
+ And:\r
+ css (may be omitted)\r
+ is a quoted string with the CSS class (e.g. 'ovfl510' for\r
+ .ovfl510 {width:510px; height:145px; overflow:auto; ...} ) for a div to\r
+ encase the responseText and set the width, height and scrollbars in the\r
+ main text area of the popup, or the unquoted number 0 if no encasing div\r
+ is to be used.\r
+\r
+ For POST substitute OLpostAJAX(url, qry, command, delay, css);\r
+ Where\r
+ qry (required)\r
+ is the string to be posted, typically a query string (without a lead ?)\r
+ and the other arguments are as above.\r
+\r
