利用uniapp开发一个简单的地图导航

    this.covers = [         {            id: 1,            latitude: 34.7486,            longitude: 113.6709,            iconPath: '../../static/shop.png',            title: "目的地"        }    ];

    // 连线    this.polyline = [        // 第一条线        {            // 每个点的经纬度            points: [{34.7486, 113.6709}, {28.7486, 113.6709}],            // 颜色            color: "#000",            // 宽度            width: 10        }    ]

// 回到定位点goBackToLocation() {   uni.createMapContext("map").moveToLocation({34.7486, 113.6709});},

    // 导航 会打开导航菜单供用户选择    openNavigation(longitude, latitude, name) {        let url = ""; // app url        let webUrl = ""; // web url 用来为用户未安装导航软件时打开浏览器所使用url        plus.nativeUI.actionSheet({ //选择菜单            title: "选择地图应用",            cancel: "取消",            buttons: [{title: "高德地图"}] // 可选的地图类型        }, (e)=> {                // 判断用户选择的地图            switch (e.index) {                //下面是拼接url,不同系统以及不同地图都有不同的拼接字段                case 1:                    // 安卓                    if(plus.os.name == "Android") {                        url = `androidamap://viewMap?sourceApplication=appname&poiname=${name}&lat=${latitude}&lon=${longitude}&dev=0`;                    }else {                        url = `iosamap://viewMap?sourceApplication=applicationName&poiname=${name}&lat=${latitude}&lon=${longitude}&dev=0`;                    }                    webUrl = `https://uri.amap.com/marker?position=${longitude},${latitude}&name=${name}&src=mypage&coordinate=gaode`                    break;            }                // 如果选中            if (url != "") {                url = encodeURI(url);                // 打开 app 导航                 plus.runtime.openURL(url, (err)=>{ // 失败回到                    // 如果失败则说明未安装 直接 打开网页版进行导航                    // 毕竟用户可能没有安装app但一定安装的有浏览器                    plus.runtime.openURL(webUrl);                });            }    })}
