I corrected the code but still I don't understand a thing.. when I go on
the WGS-84 map (http://www.intornoamessina.it/tracking/) and I point the
mouse at a certain point of coordinate -93.2735, 44.8349 the result is
like 4613718.1118, 1718560.9374, should not be like the coordinates before?
Many Thanks
Valerio

OpenLayers.Util.getFormattedLonLat(lat)is for formating geographic
coordinates,
but you pass projected coordinates to the function. That's the reason
for the strange output.
Util.js:
OpenLayers.Util.getFormattedLonLat = function(coordinate, axis,
dmsOption) {
if (!dmsOption) {
dmsOption = 'dms'; //default to show degree, minutes, seconds
}
coordinate = (coordinate+540)%360 - 180; // normalize for sphere
being round
...
Choose displayProjection: geographic and if you want to output your
mousemove coordinates also in the projected coordinates,
you have to transform them.
formatOutput: function(lonLat) {
var geoCoor = lonLat.clone().transform(geographic,
mercator);
var lat = lonLat.lat;
...

Cit.:
Set the displayProjection property when you create the map to the
projection (not the projection code) that you want the coordinates to
be in. (looks like it should be a projection created from EPSG:4326)
The lat/lon being passed into the mousecontrol event will be in this
projection. It look to me like you are getting in projected
coordinates but trying to use them as lat/long.
Done but the problem remains.

Hi, I'm tryng to display the coordinates on mouse over the map, on a
WGS84 map and on a Gauss-Boaga map but coordinate seems strange to
me, is there some error? I'm using the example bellow:
This is the WGS84 map
<http://www.intornoamessina.it/tracking/index.php> and this is the
Gauss-Boaga Map <http://www.intornoamessina.it/tracking/index.php?gauss>
And this is the *example code* I used:
map.addControl(
new OpenLayers.Control.MousePosition({
prefix: '<div style=\"color: green; font-size:
14px; font-weight: bold; background-color: white; width: 500px;
text-align: left;\">Coordinate: ',
suffix: '</div>',
separator: ' | ',
numDigits: 2,
emptyString: '<div style=\"color: red; font-size:
14px; font-weight: bold; background-color: white; width: 500px;
text-align: left;\">Mouse non sulla mappa.</div>'
})
);
map.events.register("mousemove", map, function(e) {
var position = this.events.getMousePosition(e);
OpenLayers.Util.getElement("coords").innerHTML =
position;
});
map.addControl(new OpenLayers.Control.Attribution());
*Thanks**
