openlayers 构造 feature 数组

  var point1 = new OpenLayers.Geometry.Point(106,29.15);

    var myObj =
    {
        'deviceId': 101,        //属性名用引号括起来，属性间由逗号隔开
        'address': 'myName'
    };   

var fea1 = new OpenLayers.Feature.Vector(point1,myObj);
    var point2 = new OpenLayers.Geometry.Point(106,29.05);
    var fea2 = new OpenLayers.Feature.Vector(point2,my);
    var point3 = new OpenLayers.Geometry.Point(106.21,29.05);
   var fea3 = new OpenLayers.Feature.Vector(point3,myObj1);
    var v = new Array();
    v[0]=fea1;
    v[1]=fea2;
    v[2]=fea3;

var fstore = new GeoExt.data.FeatureStore({
          layer: vecLayer,
feature:v,
fields: [
              {name: 'deviceId', type: 'int'},
              {name: 'address', type: 'string'}
          ],
autoLoad: true
}）；
