'ello...

I've been toying with this javascript to make selected text a link and it's only working in IE on the PC (haven't checked safari yet...will when I get home). In Firefox I think it's because when you click "Add Link" (which is a text link), that gets focus and the focus is never going back to the textarea (which it should).

Anyone know what's up?

Code:
function GetSelectedText(elementID) {
	var txt = '';
	
	if (window.getSelection) {
		txt = window.getSelection();
	} else if (document.getSelection) {
		txt = document.getSelection();
	} else if (document.selection) {
		txt = document.selection.createRange().text;
	}
	else return;
	
	var n = prompt("Enter the URL","http://");
	if(n) {
		// replace the variable with the html
		txt = "<a href=\"" + n + "\" target=\"_blank\">" + txt + "</a>";
		SetSelectedText(elementID, txt);
	} else {
		alert("Error : no link provided");
	}
	
}


function SetSelectedText(elementID, text) {
	var obj = document.getElementById(elementID);
	if( !obj )
	throw "Element " + elementID + " not found!";
	
	// Netscape, Mozilla, Firefox
	if( typeof(obj.selectionStart) != "undefined" ) {
		obj.focus();
		var start_selection = obj.selectionStart;
		var end_selection = obj.selectionEnd;
		if (end_selection < start_selection){
			var temp = end_selection;
			end_selection = start_selection;
			start_selection = temp;
		}
		
		var startText = (obj.value).substring(0, start_selection);
		var endText = (obj.value).substring(end_selection, obj.textLength);
		
		obj.value = startText + text + endText;
		obj.selectionStart = start_selection;
		obj.selectionEnd = start_selection + text.length;
	}
		
	// Internet Explorer
	if(obj.createTextRange) {
		obj.focus( obj.caretPos );
		obj.caretPos = document.selection.createRange().duplicate();
		obj.caretPos.text = text;
		obj.caretPos.moveStart( "character", text.length * -1 );
		obj.caretPos.select();
	}
	obj.focus();
}
