高德地图api之路线规划

2024-03-07 16:01:33

基本使用步骤

1.引入

 <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=你的key"></script>

2.创建并初始化实例对象

<div id="container"></div>

const map = new AMap.Map("container")

3.创建一个导航元素,用来承载导航路线(这里不要忘了,是个坑,用的啥时候踩过,文档里没有详细说)
```
<div id="panel"></div>
```

4.使用路线规划插件
这里先拿驾车路线规划举个例子

假设var start = "*", end = "人民大会堂"

AMap.plugin('AMap.Driving', function () {
    const driving = new AMap.Driving({
          // 驾车路线规划策略，AMap.DrivingPolicy.LEAST_TIME是最快捷模式
          policy: AMap.DrivingPolicy.LEAST_TIME,
          // map 指定将路线规划方案绘制到对应的AMap.Map对象上
          map: map,
          // panel 指定将结构化的路线详情数据显示的对应的DOM上，传入值需是DOM的ID
          panel: 'panel'
     })

	const points = [
		  { keyword: start },
          { keyword: end }
    ]

    // 搜索完成后，将自动绘制路线到地图上
    driving.search(points)
})

当然不只有驾车路线规划,还有其他类型:

步行规划

AMap.plugin('AMap.Walking', function () {
                const walking = new AMap.Walking({
                    map: map,
                    panel: 'panel'
                })
                const points = [
                    { keyword: start },
                    { keyword: end }
                ]
                walking.search(points)
            })

骑行规划

AMap.plugin('AMap.Riding', function () {
                const riding = new AMap.Riding({
                    map: map,
                    panel: 'panel'
                })
                const points = [
                    { keyword: start },
                    { keyword: end }
                ]
                riding.search(points)
            })

公交规划

 AMap.plugin('AMap.Transfer', function () {
                const transfer = new AMap.Transfer({
                    map: map,
                    panel: 'panel'
                })
                const points = [
                    { keyword: start },
                    { keyword: end }
                ]
                transfer.search(points)
            })

货车规划(一天只能调用100次,超过收费)

AMap.plugin('AMap.TruckDriving', function () {
                const truckDriving = new AMap.TruckDriving({
                    map: map,
                    panel: 'panel',
                    // policy: ,
                    size: 1, // 必填, 车辆大小
                })
                const points = [
                    { keyword: start },
                    { keyword: end }
                ]
                truckDriving.search(points)
            })

以上只是简单的实现,具体的属性和方法还是要看文档的
