arcgisforjs轨迹回放
1、原理讲解:将点一个一个放入到线中的(需要直接加入实例化的poleline中),单独的用实例对象添加是无效的(1、obj.addPath或2、pl.insertpoint(x,y)也是无效的,要求实例化中的数组不能为空)例子:varmPoint=newesri.geometry.Point(45.92639474162,-18.54517187499);varmPoint1=newesri.geometry.Point(45.68131754058,44.20834374984);1、varpl=newesri.geometry.Polyline(ary);
