This is bugging me for more than two moths so any help would be appreciated.
1) Script Title: Rich HTML Balloon Tooltip

2) Script URL (on DD):here (http://www.dynamicdrive.com/dynamicindex5/balloontooltip.htm)

3) Describe problem:
I have a div with a scrollbar and links inside it. for links appearing without scrolling the div the ballontip show fine but as you scroll the div the balloontip goes further and further down, it is as if the javascript calculates the position the link would have if it weren't inside the div, a friend suggested adding the scrollTop property but I am cluless where. I have searching two months for a solution and founded nothing can anyone help?
Surely the problem lies with the ballontip.js which code follows


//Rich HTML Balloon Tooltip: http://www.dynamicdrive.com/dynamicindex5/balloontooltip.htm
//Created: September 10th, 2006

var disappeardelay=250 //tooltip disappear delay (in miliseconds)
var verticaloffset=0 //vertical offset of tooltip from anchor link, if any
var enablearrowhead=1 //0 or 1, to disable or enable the arrow image
var arrowheadimg=["arrowdown.gif", "arrowup.gif"] //path to down and up arrow images
var arrowheadheight=11 //height of arrow image (amount to reveal)

/////No further editting needed

var ie=document.all
var ns6=document.getElementById&&!document.all
verticaloffset=(enablearrowhead)? verticaloffset+arrowheadheight : verticaloffset

function getposOffset(what, offsettype){
var totaloffset=(offsettype=="left")? what.offsetLeft : what.offsetTop;
var parentEl=what.offsetParent;
while (parentEl!=null){
totaloffset=(offsettype=="left")? totaloffset+parentEl.offsetLeft : totaloffset+parentEl.offsetTop;
parentEl=parentEl.offsetParent;
}
return totaloffset;
}

function showhide(obj, e){
dropmenuobj.style.left=dropmenuobj.style.top="-500px"
if (e.type=="mouseover")
obj.visibility="visible"
}

function iecompattest(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}

function clearbrowseredge(obj, whichedge){
if (whichedge=="rightedge"){
edgeoffsetx=0
var windowedge=ie && !window.opera? iecompattest().scrollLeft+iecompattest().clientWidth-15 : window.pageXOffset+window.innerWidth-15

return edgeoffsetx
}
else{

var topedge=ie && !window.opera? iecompattest().scrollTop : window.pageYOffset

dropmenuobj.contentmeasure=dropmenuobj.offsetHeight
if (windowedge-dropmenuobj.y < dropmenuobj.contentmeasure) //move up?
edgeoffsety=dropmenuobj.contentmeasure+obj.offsetHeight+(verticaloffset*2)
return edgeoffsety
}
}

function displayballoontip(obj, e){ //main ballooon tooltip function
if (window.event) event.cancelBubble=true
else if (e.stopPropagation) e.stopPropagation()
if (typeof dropmenuobj!="undefined") //hide previous tooltip?
dropmenuobj.style.visibility="hidden"

displaytiparrow()
}

function displaytiparrow(){ //function to display optional arrow image associated with tooltip
tiparrow=document.getElementById("arrowhead")
tiparrow.src=(edgeoffsety!=0)? arrowheadimg[0] : arrowheadimg[1]
var ieshadowwidth=(dropmenuobj.filters && dropmenuobj.filters[0])? dropmenuobj.filters[0].Strength-1 : 0
//modify "left" value depending on whether there's no room on right edge of browser to display it, respectively
tiparrow.style.left=(edgeoffsetx!=0)? parseInt(dropmenuobj.style.left)+dropmenuobj.offsetWidth-tiparrow.offsetWidth-10+"px" : parseInt(dropmenuobj.style.left)+5+"px"
//modify "top" value depending on whether there's no room on right edge of browser to display it, respectively
tiparrow.style.top=(edgeoffsety!=0)? parseInt(dropmenuobj.style.top)+dropmenuobj.offsetHeight-tiparrow.offsetHeight-ieshadowwidth+arrowheadheight+"px" : parseInt(dropmenuobj.style.top)-arrowheadheight+"px"

}

function delayhidemenu(){
delayhide=setTimeout("dropmenuobj.style.visibility='hidden'; dropmenuobj.style.left=0; if (enablearrowhead) tiparrow.style.visibility='hidden'",disappeardelay)
}

function clearhidemenu(){
if (typeof delayhide!="undefined")
clearTimeout(delayhide)
}

function reltoelement(linkobj){ //tests if a link has "rel" defined and it's the ID of an element on page
var relvalue=linkobj.getAttribute("rel")
return (relvalue!=null && relvalue!="" && document.getElementById(relvalue)!=null && document.getElementById(relvalue).className=="balloonstyle")? true : false
}

function initalizetooltip(){
var all_links=document.getElementsByTagName("a")
if (enablearrowhead){
tiparrow=document.createElement("img")
tiparrow.setAttribute("src", arrowheadimg[0])
tiparrow.setAttribute("id", "arrowhead")
document.body.appendChild(tiparrow)
}
for (var i=0; i<all_links.length; i++){
if (reltoelement(all_links[i])){ //if link has "rel" defined and it's the ID of an element on page
all_links[i].onmouseover=function(e){
var evtobj=window.event? window.event : e
displayballoontip(this, evtobj)
}
all_links[i].onmouseout=delayhidemenu
}
}
}

if (window.addEventListener)
window.addEventListener("load", initalizetooltip, false)
else if (window.attachEvent)
window.attachEvent("onload", initalizetooltip)
else if (document.getElementById)
window.onload=initalizetooltip


After some mods in lines 17 and 20 where substracted the scrollTop property (in the function getposOffset when putting a value in totalofset) the javasrcipt runs fine in IE but not on firefox/safari. Why?
Themodificated ballontip.js now is

If you want to see the problem go (with anything besides IE) here (http://www.generalmusic.gr/index.php?var=&page=7&kwd=9.00009), scroll the div and hover above a link the futher down the link the further out of place is the ballon showing.

Plz help and many thanks for your time

Hi,

I'm having this same problem with the same exact code, did you find a solution?

Thanks...
