esri.layers.FeatureLayer is not a constructor error

BenReilly — Mon, 27 Jun 2011 15:47:00 GMT

I'm trying to add a layer to a javascript map, but I keep getting an error that esri.layers.FeatureLayer is not a constructor. I can only find one post about this, where that person was not using dojo.addOnLoad. I've included my code- what is causing this?

<head>
<script src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.3" type="text/javascript"></script>
<link href="http://serverapi.arcgisonline.com/jsapi/arcgis/2.3/js/dojo/dijit/themes/claro/claro.css" rel="stylesheet" type="text/css" >

<script type="text/javascript">
  dojo.require("esri.map");
  dojo.require("esri.layers.FeatureLayer");
  var map;
  var campus;
function init() {
  map = new esri.Map("mapDiv");
  var spatialRef = new esri.SpatialReference({wkid:4326});
  var startExtent = new esri.geometry.Extent();
  startExtent.xmin = -88.7491;
  startExtent.ymin = 42.8345;
  startExtent.xmax = -88.7368;
  startExtent.ymax = 42.8433;
  startExtent.SpatialReference = spatialRef;


  map.setExtent(startExtent);
  var mapServiceURL = "http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer";
  map.addLayer(new esri.layers.ArcGISTiledMapServiceLayer(mapServiceURL));
  
  campus = new esri.layers.FeatureLayer("http://[SERVER]/ArcGIS/rest/services/campusjava1/MapServer/0");


}


  dojo.addOnLoad(init);
  
</script>
</head>
<body OnLoad="init()" class="claro">
  <div id="mapDiv" style="width:1000px; height:800px; border:1px solid #000;"></div>
</body>

Remove the "OnLoad="init()"" from your body tag.

I took that bit out, but my layer still isn't showing up.

Still getting the same error?

The constructor error went away. I guess it might be a problem with our server, since no other errors are showing up. Thanks for the quick help!

It's working now? Glad to help!

No, it's still not showing up, but the original error went away.

You'll also want to add your feature layer to the map after you create it:

map.addLayer(campus);

That's got it showing up! Thank you again, I appreciate it!
