得到了这个代码： var sitePoints = []; var siteStyle = { // style_definition }; var epsg4326 = new OpenLayers.Projection("EPSG:4326"); for (var i in coordinates) { var coord = coordinates[i]; var point = new OpenLayers.Geometry.Point(coord.lng, coord.lat); // transform from WGS 1984 to Spherical Mercator point.transform(epsg4326, map.getProjectionObject()); sitePoints.push(point); } sitePoints.push(sitePoints[0]); var linearRing = new OpenLayers.Geometry.LinearRing(sitePoints); var geometry = new OpenLayers.Geometry.Polygon([linearRing]); var polygonFeature = new OpenLayers.Feature.Vector(geometry, null, siteStyle); vectors.addFeatures([polygonFeature]);... 展开详请
