1. 步骤

1) 全局变量

          var map, layer0, pointLayer;

2) 添加地图容器

//            创建地图容器
            map = new OpenLayers.Map('map1',
                    {
                        controls: [
                            new OpenLayers.Control.PanZoomBar(),//缩放面板的工具控件
                            new OpenLayers.Control.LayerSwitcher(), //图层切换控件
                            new OpenLayers.Control.Navigation(),    //此控件处理伴随鼠标事件的地图浏览
                            new OpenLayers.Control.MousePosition()//此控件显示鼠标移动时，所在点的地理坐标
                        ]
                    }
            );

3) 添加第三方地图图层

//            添加图层0
            layer0 = new Zondy.Map.GoogleLayer("Google Map VEC",
                    {
//                        添加GoogleMap的矢量图层
                        layerType: Zondy.Enum.GoogleLayerType.VEC,
//                        设为底图
                        isBaseLayer: true
                    }
            );

4) 将图层添加到地图容器中

          map.addLayers([layer0,layer1,layer2]);

5) 在地图上创建点图层

          pointLayer = new OpenLayers.Layer.Vector("MDZZ");

6) 创建几何点并生成点要素

         //传入坐标创建几何点           
          var pointGeom = new OpenLayers.Geometry.Point(858585,154654) ;
          //生成点要素
          var pointFeature = new OpenLayers.Feature.Vector(pointGeom);
 
          var pointGeom1 = new OpenLayers.Geometry.Point(9893585,4344069);//创建几何点
          var pointFeature1 = new OpenLayers.Feature.Vector(pointGeom1);//生成点要素

          var pointGeom2 = new OpenLayers.Geometry.Point(9314310, 3717894);//创建几何点
          var pointFeature2 = new OpenLayers.Feature.Vector(pointGeom2);//生成点要素

7) 将点添加到图层中

          pointLayer.addFeatures([pointFeature,pointFeature1,pointFeature2]);//点添加到图层中

8)

        //将点图层添加到地图上
        map.addLayer(pointLayer);

6) 设置地图显示中心坐标,地图缩放等级

           <!--设置地图显示中心坐标,地图缩放等级-->
           map.setCenter(new OpenLayers.LonLat(0, 0), 2);
