Attribute field names

Question

Is there a way I can get just the field names of the layer. It would have made sense if layerInfo function could get attribute field names as well

Thanks Derek. Good to know that I can use feature layer with 9.31 also

You can use a Feature Layer if you're using a 2.x version of the API. Here's a simple page that uses the 2.3 version of the API and a feature layer based on a 9.31 ArcGIS Server instance: FeatureLayer On Demand

To use esri.request(), you would make a request to your map service layer endpoint and pull the info you need out of the fields array, here's an example:// use esri.request to get field info esri.request({ url: 'http://gis.apfo.usda.gov/ArcGIS/rest/services/CONUS/Overview/MapServer/1', content: { f: 'json' }, callbackParamName: 'callback', load: function(resp) { dojo.forEach(resp.fields, function(field) { console.log('field name is ', field.name, ' and field alias is ', field.alias); }); }, error: function(err) { console.log('err: ', err); } });

Hello,
      Unfortunately I have server 9.3.1, so I cannot use feature layer. Can you please tell me how to exactly use esri.request() in the javascript API, and how can I handle the response.

Thanks
