准备:

1、注册百度地图api账号,地址:百度地图开放平台

2、进入控制台 - 应用管理 - 我的应用 - 创建应用,填写相关信息

开始:

1、新建页面,在script标签中引入百度地图的api数据,把自己在控制台创建的应用的ak替换上去
    <script type="text/javascript" src="https://api.map.baidu.com/api?v=1.0&&type=webgl&ak=这里替换成自己的ak">
    </script>
2、创建一个dom对象,设置宽高
<div id="map" class="mapBox"></div>
3、在js中初始化地图
// 初始化地图
initMap(){
    var map = new BMapGL.Map("map");//绑定创建的dom元素的id
    var point = new BMapGL.Point(116.404, 39.915);  // 创建点坐标 
    map.centerAndZoom(point, 15); // 初始化地图,设置中心点坐标和地图级别
    map.enableScrollWheelZoom(true);     //开启鼠标滚轮缩放
},

完成以上步骤就能看到基础的一张地图了

进阶:

1、地图标注

实现效果,点击地图弹出弹框,输入信息,添加一个标注点。

要实现该效果首先要监听点击事件

this.map.addEventListener('click', this.addLabel);

点击添加标注点

// 添加地图标点
addLabel(e) {
    let that = this
    var point =  new BMapGL.Point(e.latlng.lng, e.latlng.lat)
    var mk = new BMapGL.Marker(point);
    console.log(mk);
    this.$prompt('请输入内容', '提示', {
    confirmButtonText: '确定',
    cancelButtonText: '取消',
    }).then(({ value }) => {
        mk.id = Math.random()*100000000000000000
        mk.text = value?value:''
        console.log(mk);
        this.mkList.push({id:mk.id,text:mk.text,latLng:mk.latLng})
        this.map.addOverlay(mk);
        var opts = {
            width : 200,     // 信息窗口宽度
            height: 100,     // 信息窗口高度
            title : "" , // 信息窗口标题
            message:""
        }
        var infoWindow = new BMapGL.InfoWindow(value?value:'', opts);  // 创建信息窗口对象 
        mk.addEventListener("click", function(e){
            that.map.openInfoWindow(infoWindow, point); //开启信息窗口
        });
    }).catch(() => {
        
    });
},

删除标点(根据添加时生成的id去标点集合里匹配,删除对应id 的数据)

// 删除地图标点
deleteLabelById(id){
    var allOverlay = this.map.getOverlays();
    for (var i = 0; i < allOverlay.length ; i++){
        if(allOverlay[i].id&&allOverlay[i].id==id){
            this.map.removeOverlay(allOverlay[i]);
        }
    }
},
2、定位
// 获取定位
var geolocation = new BMapGL.Geolocation();
geolocation.getCurrentPosition(function(r){
    if(this.getStatus() == BMAP_STATUS_SUCCESS){
        map.centerAndZoom(r.point, 15); //r.point就是当前定位坐标,设置为地图中心点
        var mk = new BMapGL.Marker(r.point); 
        map.addOverlay(mk);//添加标点
        map.panTo(r.point);
        console.log('您的位置:' + r.point.lng + ',' + r.point.lat);
        that.city = r.address.city
        that.address = `${r.address.province}-${r.address.city}-${r.address.district}-${r.address.street}-${r.address.street_number}号` //中文 详细地址
    }
    else {
        alert('failed' + this.getStatus());
    } 
});
3、导航

(this.p1是终点坐标,this.p2是起点坐标)

if(this.type==1){
    // 行车导航路线规划
    var output = ''
    this.driving = new BMapGL.DrivingRoute(this.map, {
        renderOptions:{map: this.map, autoViewport: true},
        onSearchComplete: function(results){
            if (that.driving.getStatus() != BMAP_STATUS_SUCCESS){
                return ;
            }
            var plan = results.getPlan(0);
            output += '总时长:' + plan.getDuration(true);  //获取时间
            output += '总路程:' + plan.getDistance(true);  //获取距离
            that.output = output
            console.log(output)
        },
    });
    // p2,p1为起点和目标点的坐标
    this.driving.search(this.p2, this.p1);
}else if(this.type==2){
    // 公交路线规划
    var output = ''
    this.transit = new BMapGL.TransitRoute(this.map,{
    renderOptions: {map: this.map,panel:'panel'},
    onSearchComplete: function(results){
            if (that.transit.getStatus() != BMAP_STATUS_SUCCESS){
                return ;
            }
            var plan = results.getPlan(0);
            output += '总时长:' + plan.getDuration(true);  //获取时间
            output += '总路程:' + plan.getDistance(true);  //获取距离
            that.output = output
            console.log(output)
        },
    });
    this.transit.search(this.p2, this.p1);
}else{
    // 步行路线规划
    var output = ''
    this.walking = new BMapGL.WalkingRoute(this.map, {
        renderOptions:{map: this.map, autoViewport: true},
        onSearchComplete: function(results){
            if (that.walking.getStatus() != BMAP_STATUS_SUCCESS){
                return ;
            }
            var plan = results.getPlan(0);
            output += '总时长:' + plan.getDuration(true);  //获取时间
            output += '总路程:' + plan.getDistance(true);  //获取距离
            that.output = output
            console.log(output)
        },
    });
    this.walking.search(this.p2, this.p1);
}
4、公交路线规划

注意:公交车导航可以配置以下参数获取公交路线规划

<div id="panel"></div>

renderOptions: {map: this.map,panel:'panel'},

6、坐标转化

目前国内主要有以下三种坐标系:

WGS84:为一种大地坐标系,也是目前广泛使用的GPS全球卫星定位系统使用的坐标系。

GCJ02:又称火星坐标系,是由中国国家测绘局制订的地理信息系统的坐标系统。由WGS84坐标系经加密后的坐标系。

BD09:为百度坐标系,在GCJ02坐标系基础上再次加密。其中bd09ll表示百度经纬度坐标,bd09mc表示百度墨卡托米制坐标。

非中国地区地图,服务坐标统一使用WGS84坐标。

百度地图需要用BD09坐标,如果是天地图坐标(WGS84),则需要作转化

WGS84 – 转–> BD09

var convertor = new BMapGL.Convertor();
let point = new BMapGL.Point(intitude,latitude) //intitude,latitude为天地图坐标
convertor.translate([point], COORDINATES_WGS84, COORDINATES_BD09, (data)=>{
    if(data.status === 0) {
        let point = data.points[0]
        if(point){
            // 此时得到的就是百度地图坐标
            console.log(point)
        }
    }
})
