I have created a ASP script using geotools now which should loop
through all of the grid references in a database.
response.write("<script type=""text/javascript"">" & vbcrlf)
response.write("function initialize() {" & vbcrlf)
response.write("if (GBrowserIsCompatible()) {" & vbcrlf)
response.write("var map = new GMap2(document.getElementById
(""map_canvas""));" & vbcrlf)
response.write("//map.setMapType(G_SATELLITE_MAP);" & vbcrlf)
response.write("map.setCenter(new GLatLng(54.228719,
-1.027345), 6);" & vbcrlf)
response.write("}" & vbcrlf)
response.write("}" & vbcrlf)
response.Write("</script>")
i = 1
do while not rs.eof
id = rs.fields("id")
'response.Write(i & "<br />")
response.write("<script langauge=""javascript"">" &
vbcrlf)
response.write("var gr=""" &
rs.fields("grid_ref") & """;" &
vbcrlf)
response.write("var osgb = new GT_OSGB();" &
vbcrlf)
'response.write("document.write(gr)" & vbcrlf)
response.write("if (osgb.parseGridRef(gr))" &
vbcrlf)
response.write("{" & vbcrlf)
response.write("var wgs84 =
osgb.getWGS84();" & vbcrlf)
response.write("var lat =
wgs84.latitude;" & vbcrlf)
response.write("var long =
wgs84.longitude;" & vbcrlf)
'response.Write("document.write(long+""
""+lat)")
response.Write("initialize();") & vbcrlf
response.write("var info = new GMarker(new
GLatLng(wgs84.latitude,
wgs84.longitude));" & vbcrlf)
response.write("map.addOverlay(info);" & vbcrlf)
response.write("info.openInfoWindowHtml(""<strong>" & rs.fields
("grid_ref") & "</strong>"");" & vbcrlf)
response.write("}" & vbcrlf)
response.Write("</script>" & vbcrlf)
i = i + 1
rs.movenext
loop
now once i run the page it loops through them all ok except that the
GLatLng in the GMarker is blank.
the source code looks like this
var gr="SD 80558 71330";
var osgb = new GT_OSGB();
if (osgb.parseGridRef(gr))
{
var wgs84 = osgb.getWGS84();
var lat = wgs84.latitude;
var long = wgs84.longitude;
initialize();
var info = new GMarker(new GLatLng(wgs84.latitude, wgs84.longitude));
map.addOverlay(info);
info.openInfoWindowHtml("<strong>SD 80558 71330</strong>");
}
any help to get these being filled in correectly?
many thanks.
