Help with JSON please

RobertoS — GMT

Hello I am trying to obtain the toponymName from http://ws.geonames.org/findNearbyPlaceNameJSON?lat=47.3&lng=9. Here is my code: Code:

$.getJSON("http://ws.geonames.org/findNearbyPlaceNameJSON?lat=47.3&lng=9", function(data){
alert(data.toponymName);
});

What am I doing wrong? Thank you. roberto

It is better to use $.ajax() with dataType:'jsonp' Have a look to geotree.html : view-source:http://geotree.geonames.org/geotree.html

OK, this is the best I can do after spending the afternoon reverse-engineering :roll: the sample script: Code:

var geonames;
function getLocation(jData)
{
  if (jData == null) {
    return;
  }
  geonames = jData.geonames;
	var placeInput = document.getElementById("placeInput").value = jData.geonames.toponymName;
}


function placeLookup()
{
  request = 'http://ws.geonames.org/findNearbyPlaceNameJSON?lat=47.3&lng=9&callback=getLocation';
  aObj = new JSONscriptRequest(request);
  aObj.buildScriptTag();
  aObj.addScriptTag();
}

What am I missing? Thanks!

$(function() { $.ajax({ url: 'http://ws.geonames.org/findNearbyPlaceNameJSON', dataType:'jsonp', data: { lat: '47.3', lng: '9', }, success:function(response) { alert(response.geonames.length); alert(response.geonames[0]); } }); }); OK, so this is giving me an array of length 1 (good). But how do I retrieve the "toponymName"? Thanks for your help. Roberto

This is the power of json : javascript data from 'response' array have exactly the same name as in the json demo output : view-source:http://ws.geonames.org/findNearbyPlaceNameJSON?formatted=true&lat=47.3&lng=9&style=full Code:

success: function(response) {
	// ws returns an error message
	if (response.status) {
		alert(response.status.message+response.status.value);
	}
	// ws returns an array of data
	if (response.geonames && response.geonames.length) {
		$.each(response.geonames, function() {
			alert(this.fcode);
			alert(this.toponymName);
			etc...
		}
	}
}

Once again, have a look to geotree.html : view-source:http://geotree.geonames.org/geotree.html
