I think, I've found a bug in MochiKit.Style.getElementPosition on Opera.
When selecting the position of an element, contained in a table cell,
the position isn't calculated correctly.
Quirksmode findPos function gets the right result, for reference:
http://www.quirksmode.org/js/findpos.html
Test below:
<html>
<head>
<title>getElementPosition vs Opera</title>
<script type="text/javascript" src="mochikit.js"></script>
<style type="text/css">
html, body { margin:0; padding:0; }
</style>
<script type="text/javascript">
quirksmode = {};
quirksmode.findPos = function(obj) {
var curleft = curtop = 0;
if (obj.offsetParent) {
curleft = obj.offsetLeft
curtop = obj.offsetTop
while (obj = obj.offsetParent) {
curleft += obj.offsetLeft
curtop += obj.offsetTop
}
}
return {x: curleft, y: curtop, __repr__:
MochiKit.Style.Coordinates.prototype.__repr__ };
}
addLoadEvent(function() {
$("debug").innerHTML = repr(getElementPosition($("street")));
$("debug").innerHTML += "<br>";
$("debug").innerHTML += repr(quirksmode.findPos($("street")));
});
</script>
</head>
<body>
<table>
<tbody>
<tr><td style="height:100px"> </td></tr>
<tr><td><img src="#" id="street" alt="Element to get position
from" /></td></tr>
</tbody>
</table>
<div id="debug" style="font-size:100pt;font-family:'trebuchet ms'"></div>
<div
style="height:100px;width:10px;background-color:red;position:absolute;top:0;right:0;"> </div>
</body>
</html>
