Hi!
I am a beginner in GIS and maps programming. I try to do a certain
project but I have some problems. Here is my code:
OpenLayers.Control.Click = OpenLayers.Class(OpenLayers.Control, {
defaultHandlerOptions: {
'single': true,
'double': false,
'pixelTolerance': 0,
'stopSingle': false,
'stopDouble': false
},
initialize: function(options) {
this.handlerOptions = OpenLayers.Util.extend(
{}, this.defaultHandlerOptions
);
OpenLayers.Control.prototype.initialize.apply(
this, arguments
);
this.handler = new OpenLayers.Handler.Click(
this, {
'click': this.trigger
}, this.handlerOptions
);
},
trigger: function(e) {
var lonlat = map.getLonLatFromViewPortPx(e.xy);
document.getElementById('lat').value =
lonlat.lat.toString();
document.getElementById('lng').value =
lonlat.lon.toString();
}
});
var map;
function init(){
map = new OpenLayers.Map('map');
var layerMapnik = new
OpenLayers.Layer.OSM.Mapnik("Mapnik");
var ol_wms = new OpenLayers.Layer.WMS( "OpenLayers
WMS",
"http://labs.metacarta.com/wms/vmap0?";, {layers:
'basic'} );
map.addLayers([layerMapnik, ol_wms]);
map.addControl(new OpenLayers.Control.LayerSwitcher());
// map.setCenter(new OpenLayers.LonLat(0, 0), 0);
map.zoomToMaxExtent();
var click = new OpenLayers.Control.Click();
map.addControl(click);
click.activate();
}
On click event(only on Mapnik layer) I received some data, but it is
not longitude and latitude. And my question is how to convert it to
get properly values(lat, lon)?
With kind regards
snipe
