map

地图。

marker

支持的地图类型

marker

标记点用于在地图上显示标记的位置

marker 上的气泡 callout

marker 上的自定义气泡 customCallout customCallout存在时将忽略callout与title属性。自定义气泡采用采用cover-view定制，灵活度更高。

使用方式如下，map 组件下添加名为 callout 的 slot 节点，其内部的 cover-view 通过 marker-id 属性与 marker 绑定。当 marker 创建时，该 cover-view 显示的内容将作为 callout 显示在标记点上方。

<map>
  <cover-view slot="callout">
    <cover-view marker-id="1"></cover-view>
    <cover-view marker-id="2"></cover-view>
  </cover-view>
</map>

marker 上的气泡 label

polyline

指定一系列坐标点，从数组第一项连线至最后一项。绘制彩虹线时，需指定不同分段的颜色，如 points 包含 5 个点，则 colorList 应传入 4 个颜色值；若 colorList 长度小于 points.length - 1，则剩下的分段颜色与最后一项保持一致。

circle

在地图上显示圆

polygon

指定一系列坐标点，根据 points 坐标数据生成闭合多边形

setting

提供 setting 对象统一设置地图配置。同时对于一些动画属性如rotate和skew，通过setData分开设置时无法同时生效，需通过settting统一修改。

const setting = {
  skew: 0,
  rotate: 0,
  showLocation: false,
  showScale: false,
  subKey: '',
  layerStyle: 1,
  enableZoom: true,
  enableScroll: true,
  enableRotate: false,
  showCompass: false,
  enable3D: false,
  enableOverlooking: false,
  enableSatellite: false,
  enableTraffic: false,
}
this.setData({
  // 仅设置的属性会生效，其它的不受影响
  setting: {
    enable3D: true,
    enableTraffic: true
  }
})

regionchange 返回值

视野改变时，regionchange 会触发两次，返回的 type 值分别为 begin 和 end。

e = {causedBy, type, detail: {rotate, skew, scale, centerLocation, region}}

Tips：

• 地图组件集成了各厂家地图的 JavaScript 版本，需要开发者自行申请对应的key，使用 subKey 设置
• 根据设置的地图类型，请你使用对应地图的坐标系坐标
• subSetting 可通过此属性添加未集成的控件属性，属性值参考各地图的 JS API文档
