做个记录

百度之给了线,圆的经纬度点获取,没给多边形
有个p.getPath().length
所以对于 多边形和矩形 是个点的轨迹数组
drawingManager.addEventListener('polygoncomplete', function(e,p){
debugger var point = p.getPath(); var str1=""; for(var i = 0;i<point.length;i++){ str1 += "("+point[i].lng+","+point[i].lat+"),"; } countOverlays++; alert("该覆盖物是多边形,"+str1); });drawingManager.addEventListener('rectanglecomplete', function(e,p){ debugger var point = p.getPath(); var str=""; for(var i = 0;i
