微信小程序map组件设置属性不起作用

<map 
    name="mapto" 
    longitude="{{longitude}}" 
    scale="18" 
    latitude="{{latitude}}"
    show-compass="{{showCompass}}"
    enable-3D="{{enable3D}}"
    enable-overlooking="{{enableOverlooking}}"
    skew="{{skew}}"></map>

data: {
        latitude:0,
        longitude:0,
        scale:18,
        showCompass:true,
        enable3D:true,
        enableOverlooking:true,
        skew:20,

        setting:{
        }
    },

是对接的哪个地图，引入相关js了嘛
