offset top calculation problem

[Michael Hill]

If I have a button defined as:
<input type="button" name="zzz">

I can determine the top position using the function getOffsetTop below
like:
var tableTop = getOffsetTop(zz zz); //and I get a valid
value

However if I have another function involved where the button name is
being passed to it I'm having a problem not knowing how to call this.

onclick=temp(zz zz);

function temp(mybutton)
{
var tableTop = getOffsetTop(my button);
}

function getOffsetTop (el)
{
var ot = el.offsetTop;
while ( ( el = el.offsetParent ) != null )
{
ot += el.offsetTop;
}
return ot;
}

I'm sorry I didn't mean a button, I meant a link

should have been:
