Vue+OpenLayers 创建地图并显示鼠标所在经纬度_ol & formataxirs

1、效果

2、创建地图

本文用的是高德地图
页面

 <div class="map" id="map"></div>
                    <div id="mouse-position" class="position_coordinate"></div>

初始化地图

     var gaodeLayer = new TileLayer({
          title: "高德地图",
          source: new XYZ({
            url: 'http://wprd0{1-4}.is.autonavi.com/appmaptile?lang=zh_cn&size=1&style=7&x={x}&y={y}&z={z}',
            wrapX: false
          })
        });
        this.map = new Map({
          layers: [gaodeLayer],
          target: 'map',
          view: new View({
            center: transform([123.23, 25.73], 'EPSG:4326', 'EPSG:3857'), //地图初始中心点
            projection: 'EPSG:3857',
            zoom: 4,
            minZoom: 1

          }),
        });

3、添加经纬度

   var mousePositionControl = new MousePosition({
          coordinateFormat: function (coordinate) {
            return formatAxirs(coordinate, '经度:{x} 纬度:{y}', 2);
          },
          projection: 'EPSG:4326',
          className: "custom-mouse-position",
          target: document.getElementById("mouse-position"), //将位置数据放到那里
          undefinedHTML: "",
        });
        this.map.addControl(mousePositionControl);

        draw: null,
      };
    },
    mounted() {
      this.initMap();

    },
      methods: {
     //初始化地图
      initMap() {

        });
        this.map = new Map({
          layers: [gaodeMapLayer],
          target: 'map',
          view: new View({
            center: transform([103.23, 35.33], 'EPSG:4326', 'EPSG:3857'), //地图初始中心点

            zoom: 4,
            minZoom: 1

          }),
        });

        // 获取鼠标在地图的经纬度
        var mousePositionControl = new MousePosition({
          coordinateFormat: function (coordinate) {
            return formatAxirs(coordinate, '经度:{x} 纬度:{y}', 2);
          },
          projection: 'EPSG:4326',
          className: "custom-mouse-position",
