Question

请问用OpenLayers 在地图上画简单的轨迹怎么画呢！

Answer 1

//使用OpenLayers.Layer.Vector，map要先建立 var vectors,lineFeature;//存放线路//线路样式var style_green = { strokeColor: "#00FF00", strokeWidth: 3, strokeDashstyle: "dashdot", pointRadius: 6, pointerEvents: "visiblePainted"};//画线图层设置 var layer_style = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default']); layer_style.fillOpacity = 0.2; layer_style.graphicOpacity = 1;//画线图层vectors = new OpenLayers.Layer.Vector("Simple Geometry", {style: layer_style}); map.addLayer(vectors); //一下采用数组型式填充轨迹 var pointList = []; for(var i=0;i<5;i++){ newPoint = new OpenLayers.Geometry.Point(lon,lan);
