posting coordinates into a tooltip?

How can I get the x/y coordinates of an area and then post them into a tooltip which follows the mouse?

I can get the coordinates and show them in a <p> tag or <div> tag location by calling my function, however, I cannot get them to display to the tooltip which calls its own function. Therefore, I need help crossing the bridge from coord() into tootip().

Why don;t you show us the code that you are using and we can help you integrate the two.

I am using scripts I located at dynamicdrive.com since I don't know much about javascript. Here they are and thanks for your help:

*** This is the tooltip code****


< style type="text/css" <

#dhtmltooltip{
position: absolute;
width: 150px;
border: 2px solid black;
padding: 2px;
background-color: lightyellow;
visibility: hidden;
z-index: 100;
/*Remove below line to remove shadow. Below line should always appear last within this CSS*/
filter: progid XImageTransform.Microsoft.Shadow(color=gray,direction=135);
}

< /style <



< div id="dhtmltooltip" < < /div <


< script type="text/javascript" <

/***********************************************

var offsetxpoint=-60 //Customize x offset of tooltip
var offsetypoint=20 //Customize y offset of tooltip
var ie=document.all
var ns6=document.getElementById && !document.all
var enabletip=false
if (ie||ns6)
var tipobj=document.all? document.all["dhtmltooltip"] : document.getElementById? document.getElementById("dhtmltooltip") : ""

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

function ddrivetip(thetext, thecolor, thewidth){
if (ns6||ie){
if (typeof thewidth!="undefined") tipobj.style.width=thewidth+"px"
if (typeof thecolor!="undefined" && thecolor!="") tipobj.style.backgroundColor=thecolor
tipobj.innerHTML=thetext
enabletip=true
return false
}
}

function positiontip(e){
if (enabletip){
var curX=(ns6)?e.pageX : event.clientX+ietruebody().scrollLeft;
var curY=(ns6)?e.pageY : event.clientY+ietruebody().scrollTop;
//Find out how close the mouse is to the corner of the window
var rightedge=ie&&!window.opera? ietruebody().clientWidth-event.clientX-offsetxpoint : window.innerWidth-e.clientX-offsetxpoint-20
var bottomedge=ie&&!window.opera? ietruebody().clientHeight-event.clientY-offsetypoint : window.innerHeight-e.clientY-offsetypoint-20

var leftedge=(offsetxpoint < 0)? offsetxpoint*(-1) : -1000

//if the horizontal distance isn't enough to accomodate the width of the context menu
if (rightedge < tipobj.offsetWidth)
//move the horizontal position of the menu to the left by it's width
tipobj.style.left=ie? ietruebody().scrollLeft+event.clientX-tipobj.offsetWidth+"px" : window.pageXOffset+e.clientX-tipobj.offsetWidth+"px"
else if (curX < leftedge)
tipobj.style.left="5px"
else
//position the horizontal position of the menu where the mouse is positioned
tipobj.style.left=curX+offsetxpoint+"px"

//same concept with the vertical position
if (bottomedge < tipobj.offsetHeight)
tipobj.style.top=ie? ietruebody().scrollTop+event.clientY-tipobj.offsetHeight-offsetypoint+"px" : window.pageYOffset+e.clientY-tipobj.offsetHeight-offsetypoint+"px"
else
tipobj.style.top=curY+offsetypoint+"px"
tipobj.style.visibility="visible"
}
}

function hideddrivetip(){
if (ns6||ie){
enabletip=false
tipobj.style.visibility="hidden"
tipobj.style.left="-1000px"
tipobj.style.backgroundColor=''
tipobj.style.width=''
}
}

document.onmousemove=positiontip

< /script <

onM < ouseover="ddrivetip('JavaScriptKit.com JavaScript tutorials','yellow', 300)";
onM < ouseout="hideddrivetip()"

ddrivetip('TEXT TO DISPLAY', 'OPTIONAL BACKGROUND COLOR', OPTIONAL TIP WIDTH)


**** This is the coordinates code ****

--- this is in the td tag ---



onM < ouseMove="updateDisplay(event)"
onM < ouseOut="clearDisplay ();"

--- this is in the head ----



< SCRIPT <
// update the mouse coordinates display
function updateDisplay(event) {
c = document.getElementById("coordinates");
c.innerHTML = event.clientX + ", " + event.clientY;
}

function clearDisplay() {
c = document.getElementById("coordinates");
c.innerHTML = " X and Y coordinates";
}
< /script <



--- in the p tag to display the coordinates in a static location----

Coordinates: < span id=coordinates < X and Y coordinates
< /span <
