// HISTORY
// ------------------------------------------------------------------
// December 9, 2003: Added script to the Javascript Toolbox
// December 10, 2003: Added the preProcessTrees variable to allow user
//      to turn off automatic conversion of UL's onLoad
// March 1, 2004: Changed it so if a <li> has a class already attached
//      to it, that class won't be erased when initialized. This allows
//      you to set the state of the tree when painting the page simply
//      by setting some <li>'s class name as being "liOpen" (see example)

// Namn: ajax(inControl, inURL)
// Kort beskrivning: Funktionen anropar valfri fil via ajax
// Indata: 
// inControl : id på det input, span eller div som skall tilldelas output av den anropade filen
// inURL: sökvägen till den fil som ska anropas, skickas med GET, dvs. vi kan lägga till ?func=callme&id=54 om vi vill.
// Version: 1.0
// Senast ändrad: Michael Melander 2006-11-02
//	- Lade till funktionalitet för div, span och button (kan möjligen fungera för andra också)
//
// Tidigare ändrad: Bernt Johansson 2006-09-21
//
// Exempel: 	<input type="button" onClick="ajax('elementId', 'anropadFil.php');" value="Tryck här" />
//				<input type="button" onClick="ajax('elementId', 'anropadFil.asp?func=callMe');" value="Tryck här" />
