div placering

<script type="text/javascript" language="javascript">

function initPage(){
    posDiv();
}

function posDiv(){
    objDiv = document.getElementById("divPlace");
    objDiv.style.left = document.documentElement.offsetWidth/2 - 100;
    objDiv.style.top = document.documentElement.offsetHeight/2 - 100 + document.body.scrollTop;
}


window.onload = initPage;
window.onscroll = posDiv;
window.onresize = posDiv;

</script>

<div style="position:absolute;" id="divPlace">
    <font style="background-color:#FF0033; width:200px;height:200px;">Hello World</font>
</div>

Mangler lige x.scroll:

<script type="text/javascript" language="javascript">

function initPage(){
    posDiv();
}

function posDiv(){
    objDiv = document.getElementById("divPlace");
    objDiv.style.left = document.documentElement.offsetWidth/2 - 100 + document.body.scrollLeft;
    objDiv.style.top = document.documentElement.offsetHeight/2 - 100 + document.body.scrollTop;
    document.getElementById("test").innerText = "Left: " +objDiv.style.left + ", Top: " +objDiv.style.top;
}


window.onload = initPage;
window.onscroll = posDiv;
window.onresize = posDiv;

</script>

<div style="position:absolute;" id="divPlace">
    <font style="background-color:#FF0033; width:200px;height:200px;">Hello World</font>
</div>
