实现过程

 

　　添加map地图组件

<map id="map" longitude="113.324520" latitude="23.099994" scale="14" controls="{{controls}}" bindcontroltap="controltap" markers="{{markers}}" bindmarkertap="markertap" polyline="{{polyline}}" bindregionchange="regionchange" show-location style="width: 100%; height: 400px;">
</map>

　　

 　　id：在控件点击事件回调会返回此id

　　　　　　markers标记点用于在地图上显示标记的位置

　　　　　　　　longitude ：经度

 　　　　　　　  latitude： 纬度

　　 scale：缩放级别，取值范围为5-18

 　　controls：控件名称

　　 bindcontroltap： 点击控件时触发，会返回control的id

　　 markers：标记点

　　 bindmarkertap：点击标记点时触发，会返回marker的id

 　　polyline：路线

 　　bindregionchange： 视野发生变化时触发

 　　show-location：显示带有方向的当前定位点

　　

　　初始化地图路线、路线

    markers: [{
