Arrays on mouseover displayed in tooltip?

Hi,

I have 3 textboxes A B C
The user can only enter single digit numbers in the textboxes, and if
they hover over a blank textbox it would give them the options through
a tooltip of what numbers are left over.
For instance if A =1, tooltip over B & C would = "2,3,4,5,6,7,8,9"
and B = 4, tooltip over C= "2,3,5,6,7,8,9"

I worked out a solution in vb, but that needs page postbacks, and I
would like to move away from that and make it smoother

So, how do I:
Write an array in javascript and calculate what is misssing if the
mouse hovers over a blank textbox and transfer whats missing to a
tooltip?


I suppose it would share the same logic of a sodoku puzzle thinking
about it, but sadly its not as exciting as that.

hover over the textbox? Use the onFocus to make it show, the onBlur to
make it go away.

onFocus="showTooltip(this)"

function showTooltip(elem){
var a = elem.form.elements['textbox1'].value;
var b = elem.form.elements['textbox2'].value;
var c = elem.form.elements['textbox3'].value;
var masterString = "0123456789";
var notUsed = masterString.replace(a,'').replace(b,'').replace(c ,'');
var notUsedArray = notUsed.split()
alert(notUsedArray)
//use the reference to elem to know where/which tooltip to display
//the results of notUsed
}

Use a simple string, replace what is used so far with blank space, then
split it to get an Array.

Thanks for the answer, I have used your code and the following code:
<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>

and written this in the pageload
C.Attributes.Add("onMouseover", "ddrivetip(showTooltip(C,'yellow',
300)")

and it works great apart from I can't transfer the notUsedArray to
appear in the textbody.
Can you help?
