BB-Codes & Opera & Cursorposition

[Orlando]

Werte Gemeinde,

ich poste regelmäßig in einem Board, das hinsichtlich der BB-Codes furchtbar antiquierten JS-Rotz nutzt. Im Grunde müsste man alles neu schreiben oder das System upgraden, das spielt's aber nicht.

Mir geht's nur um die Nutzung mit Opera. Alle BB-Codes werden nämlich am Ende der textarea eingefügt und nicht wie gewünscht an der aktuellen Position des Cursors. Irgendwie muss also die Funktionalität der BBCodes angeflanscht werden, ich Antiscripter krieg's nicht hin.

Über den Rest (navigator.userAgent :-)) will ich explizit nicht diskutieren, da offensichtlich und dennoch sinnlos. Bin nämlich kein Admin, sondern als Nutzer auf der Suche nach einem möglichst kleinen "Patch". Wo muss man schrauben?

Hier kommt die ungekürzte Wurst:

var bbtags   = new Array();  
  
// browser detection  
var myAgent   = navigator.userAgent.toLowerCase();  
var myVersion = parseInt(navigator.appVersion);  
var is_ie   = ((myAgent.indexOf("msie") != -1)  && (myAgent.indexOf("opera") == -1));  
var is_win   =  ((myAgent.indexOf("win")!=-1) || (myAgent.indexOf("16bit")!=-1));

 	document.cookie = "bbcodemode="+modeValue+"; path=/; expires=Wed, 1 Jan 2020 00:00:00 GMT;";  
}  
  
function normalMode(theForm) {  
	if (theForm.mode[0].checked) {

	}  
}  
  
function getArraySize(theArray) {  
 	for (i = 0; i < theArray.length; i++) {  
  		if ((theArray[i] == "undefined") || (theArray[i] == "") || (theArray[i] == null)) return i;  
	}  
 	  
 	return theArray.length;  
}  
  
function pushArray(theArray, value) {  
 	theArraySize = getArraySize(theArray);  
 	theArray[theArraySize] = value;  
}  
  
function popArray(theArray) {  
	theArraySize = getArraySize(theArray);
