Get KML featureData Field Attributes

[Tyler Waring]

I am trying to get access to the field attributes for a clicked on feature in a KML file with the ultimate goal of populating an info window. 

What call is necessary to get information from the KML file? 

Thanks, Tyler

Does this help?

That's kind of where I dead ended.

google.maps.event.addListener(kmlLayer, 'click', function(kmlEvent) {
  var name = kmlEvent.featureData.name;
  var text = kmlEvent.featureData.description;
  var pos = kmlEvent.latLng;
  var offset = kmlEvent.pixelOffset;
  alert(name);
  showInFormatedInfoWindow(name, text, pos, offset);
  });

function showInFormatedInfoWindow(name, text, position, offset) {
  iw.setOptions({
  content: "<div class='infowindow'><b>" + name + "<\/b><p>" + text + "<\/p><\/div>",
  position: position,
  pixelOffset: offset });
  iw.open(map);
 }

I ended up getting undefined values for kmlEvent.featureData.name and kmlEvent.featureData.description.

Not sure if there is a problem with my kml file or not. I converted it from a standard ESRI shapefile using QGIS.

If you provide a link to your map and kml file (as requested in the
posting guidelines) it would be easier to help.

Thanks Larry. 

I have a kml site up at https://sites.google.com/site/geogodesigns/kmlservices/newParcelKML.kml . I do not have a map site set up yet. I am just testing locally at this point and trying to make the switch from the ESRI/Flex world to that of the GoogleMaps/JavaScript. I'm still trying to connect all the dots. 

Thanks, Tyler

The placemarks in that kml don't have name or description tags
associated with them.

You might find the kml reference useful (if you haven't found it
already):

Thanks Larry.

If I wanted to access the attribute value for "PID", how would I do that with the Google Maps JavaScript API. I am completely missing the linkage between the JavaScript world and the kml world.

Thanks, Tyler

The documentation for google.maps.KmlFeatureData suggests it only
gives the standard KML content of its choice, and gives you no access
to <ExtendedData> content. That's not too suprising.

I think you might have to look into client-side KML parsing and
probably customise it to get at that data.

Here is an example of the US map, displaying the <name> and
<description> data in the sidebar.

Hi 

is there a way to get all feature data name on the laod complete event.

Also I wanted to display the feature data name on the left hand side and when the user clicks the name, it should position to that record on screen

can this be done
