[OpenLayers-Users] Make vector layer from JSON

[Robert Sanson]

Thanks Atle - this is what is working for me from the returned JSON:
 
var myObject = JSON.parse(response.responseText); //JSON.parse is a parser based on json2.js
var x_nztm = (+myObject.results[0].attributes.x_nztm);
var y_nztm = (+myObject.results[0].attributes.y_nztm);
var mggeom = new OpenLayers.Geometry.Point(x_nztm,y_nztm);
var mgfeat = new OpenLayers.Feature.Vector(mggeom);
mgfeat.attributes.farm_id = myObject.results[0].attributes.farm_id;
mgfeat.attributes.rapid_no = myObject.results[0].attributes.rapid_no;
mgfeat.attributes.road_name = myObject.results[0].attributes.road_name;
mgfeat.attributes.locality = myObject.results[0].attributes.locality;
var maingatewfs = new OpenLayers.Layer.Vector("Main Gate 2",
     {isBaseLayer: false,
       styleMap: style_gate, 
       extractAttributes: true });
maingatewfs.addFeatures(mgfeat);
map.addLayer(maingatewfs);

As long as you are able to parse the data, putting them on the map is a
no-brainer, pseudo-code something like:

for each feature
     - fetch x and y
     - create an OpenLayers Geometry
     - create a OpenLayers Vector feature
     - add attributes to feature if required

then add features to a layer
