实现效果:new mars3d.graphic.FixedRoute({无需单击小车,即可在地图上实现默认打开弹窗的激活效果。↓↓↓↓↓↓↓↓

1.popup的示例完全开源,可参考:功能示例(Vue版) | Mars3D三维可视化平台 | 火星科技
2.绑定的矢量数据上的弹框通过代码默认激活打开参考:功能示例(Vue版) | Mars3D三维可视化平台 | 火星科技
3.实现逻辑:在该矢量数据上bindPopup(),bindPopup之后再该小车数据上openPopup()

1.直接通过new mars3d.graphic.ModelEntity({相关矢量上绑定再激活也可以,关键代码:
graphic.bindPopup(inthtml).openPopup()
