Referere til et billede i en tabel

Det er i øvrigt noget vrøvl at det virker i IE. Det virker kun hvis billedet befinder sig udenfor tabeller, forms, etc.

OK...
First...Navigator and Internet Explorer both use the width and height properties to extract the element's width and height. However, they utilize different properties to determine the element's coordinates. Navigator uses x and y to retrieve these values, while Internet Explorer uses offsetLeft and offsetTop to do so.

A better way to define the image's position and dimensions is to first assign the image's reference to a variable.

IE and NS6 differ on what constitutes a container. However, the container is THE PARENT...in the case of a table the parent is the table.

For obtaining an absolute offset, a simple recursive algorithm which walks up the parents and adds up all the offsets will work in both:

<!-- This works for all browser types if using SHTML -->
function getAbsX(elt) { return (elt.x) ? elt.x : getAbsPos(elt,"Left"); }
function getAbsY(elt) { return (elt.y) ? elt.y : getAbsPos(elt,"Top"); }
function getAbsPos(elt,which) {
iPos = 0;
while (elt != null) {
  iPos += elt["offset" + which];
  elt = elt.offsetParent;
}
return iPos;
}

This would work with IE (just copy paste) and you could modify it to use variables for IE and NS

var trueOffsetLeft = 0;
var trueOffsetTop = 0;
var parentObject = document.all['bob'];
while (parentObject != null){
  trueOffsetLeft += parentObject.offsetLeft;
  trueOffsetTop += parentObject.offsetTop;
  parentObject = parentObject.offsetParent;
}

Jeg fandt selv en løsning og den er næsten identisk med din - så du får points. Men du skal lige skrive et svar.

-- og lige en, jumper har lavet:

function getPos(elm) {//jumper
    for(var zx=zy=0;elm!=null;zx+=elm.offsetLeft,zy+=elm.offsetTop,elm=elm.offsetParent);
    return {x:zx,y:zy}
}

Undskyld Speder...jeg altid glem'r at klikk "Abonnér"

roenving: Hvis jeg læse det rigtig...that only "walks up" one level (or breaks.  You need something like.

function getPos(elm){ //Jose Jeria (og mig!)
  var ref = elm;
  var elmOffsetTop = elmOffsetLeft = 0;

  while(ref != document.body) {
    elmOffsetTop += ref.offsetTop;
    elmOffsetLeft += ref.offsetLeft;
    ref = ref.offsetParent;
  }
  return {x:elmOffsetLeft,y:elmOffsetTop}
}
