Thanks Andrew,
My peoblem to place label of county name on county boudries center.
all three county boudries place on map perfectly with for loop but
same time I need to find center of boudries nad want to place Label on
it.
If you add map.addOverlay(geoXml) in side callback
function ,everytime only one county boudry display.If you look at tmy
code you will notice that county is displaying correctly but problem
is with label.
var county=new Array(3);
county[0]="Adams_IL";
county[1]="Cook_IL";
county[2]="Lake_IL";
for(var i=0;i<county.length;i++){
var name=county[i].split("_");
var geoXml = new GGeoXml(""http://vconsign.net/
images/"+county[i]+".kml",function() {
if (geoXml.loadedCorrectly()) {
geoXml.gotoDefaultViewport(map);
var label = new ELabel(geoXml.getDefaultCenter(),name
[0], "style1");
map.addOverlay(label); }
});
map.addOverlay(geoXml);
}
I search lot on how to place lable on google map in center of boudries
and I found this solution which is grt for me but now its looks like
its not working with for loop.
