valori ID in una text box

[lferdinando]

Ho una tabella

<table bgcolor="#FFFFCC" width="170">
<tr>
<td width="80">Latitudine</td>
<td width="10"> </td>
<td width="80">Longitudine</td>
</tr>
<tr>
<td width="80" id="lat"></td>
<td width="10">,</td>
<td width="80" id="lng"></td>
</tr>
</table>
i cui valori ID lat e Ing

derivano da questo javascritp

<script type="text/javascript">

function load() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map"));

map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
map.addMapType(G_PHYSICAL_MAP);
var center = new GLatLng(43.508721, 10.821533);
map.setCenter(center, 8);
geocoder = new GClientGeocoder();
var marker = new GMarker(center, {draggable: true});
map.addOverlay(marker);
document.getElementById("lat").innerHTML = center.lat().toFixed(5);
document.getElementById("lng").innerHTML = center.lng().toFixed(5);

GEvent.addListener(marker, "dragend", function() {
var point = marker.getPoint();
map.panTo(point);
document.getElementById("lat").innerHTML = point.lat().toFixed(5);
document.getElementById("lng").innerHTML = point.lng().toFixed(5);

});


GEvent.addListener(map, "moveend", function() {
map.clearOverlays();
var center = map.getCenter();
var marker = new GMarker(center, {draggable: true});
map.addOverlay(marker);
document.getElementById("lat").innerHTML = center.lat().toFixed(5);
document.getElementById("lng").innerHTML = center.lng().toFixed(5);

var point =marker.getPoint();
map.panTo(point);
document.getElementById("lat").innerHTML = point.lat().toFixed(5);
document.getElementById("lng").innerHTML = point.lng().toFixed(5);

});

});

}
}

var map = new GMap2(document.getElementById("map"));
map.addControl(new GLargeMapControl());

Vorrei inserire i due valori LAT e LNG in una text box da inviare successivamente con un form ad un DB
Come faccio a passare queste due variabili ad una textbox?

ciao, puoi procedere così:

document.getElementById('idtxtlat').value = center.lat().toFixed(5);
document.getElementById('idtxtlng').value = center.lng().toFixed(5);

dove idtxtlat e idtxtlng sono gli id dei textfield che dovranno memorizzare i valori di latitudine e longitudine, rispettivamente.

saluti

E' perfetto ... con qualche piccolo accorgimento funziona.
Grazie
