Question

请问用OpenLayers 在地图上画简单的轨迹怎么画呢！

Answer 1

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
