Hello all,

First let me tell you that I have searched this group and the internet
and have not been able to find the answer to my problem. It is probably
because I don't know what to look for. I did though find my question
asked in 1997 by a guy in this group but it seems that noone answered
his(my) question. As a very last resort I ask my question now.

I have a function to handle many divs. How do I pass that function the
'object' of the div, so that I may change its style.

---
<div id="layer1" style="position :absolute;top:0 ;left:0;"></div>
<script language="javas cript">
function move(divname){
divname.style.t op = 100;
}

move(window.doc ument.all.layer 1);
</script>
---

If you could give me any help it would be very much appreciated!

The code I posted results in the creation of one of three functions. The
first is a simple wrapper around the document.getEle mentById method. The
second uses the document.all collection to emulate gEBI by filtering the
results that the all collection might return. The final function simply
returns null, and will be used if the host supports neither gEBI nor the
all collection.

Part of the purpose of this code is to create a slightly more guaranteed
environment. That is, getReferenceByI d will always exist, so you can
rely on your ability to call it. All you need to do is check the return
value to make sure you have an object reference.

So, instead of:

var obj = document.getEle mentById('myEle ment');

if(obj) ...

you'd write:

var obj = getReferenceByI d('myElement');

if(obj) ...

Mike, thanks for the explanation.
You can tell, I had some understanding problems :)

function move(divname,le ft,top){
if(document.get ElementById) {
var d = document.getEle mentById(divnam e).style;
if(top) d.top = top+'px';
if(left) d.left = left+'px';
}
}

This code is not completely safe. There is no guarantee that
document.getEle mentById() will return a non-null object reference. Any
attempt to access the -style- attribute of a null object reference will
result in an error. Also, your tests -if (top)- and -if (left)- will
never allow you to set your move() to [0,y] or [x,0].

function move(divId, left, top) {
var d;
if (document.getEl ementById &&
(d = document.getEle mentById(divId) ) &&
(d = d.style)) {
if ('number' == typeof top) d.top = top + 'px';
if ('number' == typeof left) d.left = left + 'px';
}
}

will provide a slightly more robust implementation, although it still
doesn't guarantee that setting d.top/d.left will actually do anything.
