I have multiple xml files that I want to download and display onto a
single map, they will be displayed using the elabel function. I have
no problem getting a single xml file to display, but I've tried
multiple ways to include the second xml file to no avail thus far.
I'm wondering if the problem lies with the variables, using the same
variable in each loop to push the elabels? Thanks for the help...
Here is my 'starting' code for loading and displaying the two xml
files...
var mm;
var mm2;
if (GBrowserIsCompatible()) {
// Display the map, with some controls and set the initial
location
var map = new GMap2(document.getElementById("map"));
map.addControl(new GLargeMapControl3D());
map.addControl(new GScaleControl);
map.enableScrollWheelZoom();
map.setCenter(new GLatLng(38.611, -93.450), 7);
map.setMapType(G_PHYSICAL_MAP);
var logo = new GScreenOverlay("http://severeplains.com/maps/
overlays/wxornot.png", new GScreenPoint(1045, 675, "pixels",
"pixels"),new GScreenPoint(300, 150),new GScreenSize(150, 75));
map.addOverlay(logo);
// read the markers from the XML
GDownloadUrl("http://severeplains.com/maps/overlays/dewp.xml";,
function (doc) {
var elabels_dewp = [];
var xmlDoc = GXml.parse(doc);
var markers =
xmlDoc.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lon = parseFloat(markers[i].getAttribute("lon"));
var point = new GLatLng(lat,lon);
var data = markers[i].getAttribute("data");
var pri = markers[i].getAttribute("pri");
// split the markers into four arrays
if (parseInt(data) > 0 && parseInt(pri) < 5) {
var label = new ELabel(point, data, "style3");
elabels_dewp.push(label);
}
}
mm = new MarkerManager(map); // NOTE: don't use
GMarkerManager()
mm.addMarkers(elabels_dewp,0,17);
mm.refresh();
});
}
// read the markers from the XML
GDownloadUrl("http://severeplains.com/maps/overlays/visib.xml";,
function (doc) {
var elabels_visib = [];
var xmlDoc = GXml.parse(doc);
var markers =
xmlDoc.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lon = parseFloat(markers[i].getAttribute("lon"));
var point = new GLatLng(lat,lon);
var data = markers[i].getAttribute("data");
var pri = markers[i].getAttribute("pri");
// split the markers into four arrays
if (parseInt(data) > 0 && parseInt(pri) < 5) {
var label = new ELabel(point, data, "style5");
elabels_visib.push(label);
}
}
mm2 = new MarkerManager(map); // NOTE: don't
use GMarkerManager()
mm2.addMarkers(elabels_dewp,0,17);
mm2.refresh();
});
}
// display a warning if the browser was not compatible
else {
alert("Sorry, the Google Maps API is not compatible with this
browser");
}
