引入步骤:
- 在 html 中通过引入 script 标签加载API服务
- 在一个盒子元素 div 中预先准备地图容器,并在CSS样式中定义地图(容器)显示大小
- 创建并显示地图的代码
- 创建动画和标记
1. 在 html 中通过引入 script 标签加载API服务
| <script src="https://map.qq.com/api/gljs?v=1.exp&key=你申请的腾讯地图应用key"></script> |
2. 在body中预先准备地图容器,并在CSS样式中定义地图(容器)显示大小
| <div id="container"></div> | |
| #container { | |
| width: 100%; | |
| height: calc(100vh - 280px); | |
| border-radius: 10px; | |
| overflow: hidden; | |
| } | |
3. 创建并显示地图的代码
| mounted() { | |
| this.initMap() | |
| }, | |
| methods: { | |
| initMap() { | |
| //设置地图中心点 | |
| let center = new TMap.LatLng(39.984104, 116.307503); | |
| // 初始化地图 | |
| this.map = new TMap.Map('container', { | |
| zoom: 15, | |
| center: center, | |
| // baseMap: { // 设置卫星地图 | |
| // type: 'satellite' | |
| // } | |
| }); | |
| this.polylineLayer = new TMap.MultiPolyline({ | |
| map:this.map, // 绘制到目标地图 | |
| // 折线样式定义 | |
| styles: { | |
| style_blue: new TMap.PolylineStyle({ | |
| color: '#ff8d00', // 线填充色 | |
| width: 4, // 折线宽度 | |
| borderWidth: 2, // 边线宽度 | |
| borderColor: '#FFF', // 边线颜色 | |
| lineCap: 'round', // 线端头方式 | |
| eraseColor: 'rgb(172,172,172)',//擦除路径的颜色 | |
| }), | |
| }, | |
| geometries: [ | |
| { | |
| id: 'erasePath', | |
| styleId: 'style_blue', | |
| paths: this.path, | |
| }, | |
| ], | |
| }); | |
| this.marker = new TMap.MultiMarker({ | |
| map:this.map, // 绘制到目标地图 | |
| styles: { | |
| 'car-down': new TMap.MarkerStyle({ | |
| width: 40, | |
| height: 40, | |
| anchor: { | |
| x: 20, | |
| y: 20, | |
| }, | |
| faceTo: 'map', | |
| rotate: 180, | |
| src: 'https://mapapi.qq.com/web/lbs/javascriptGL/demo/img/car.png', | |
| }), | |
| start: new TMap.MarkerStyle({ | |
| width: 25, | |
| height: 35, | |
| anchor: {x: 16, y: 32}, | |
| src: 'https://mapapi.qq.com/web/lbs/javascriptGL/demo/img/start.png', | |
| }), | |
| end: new TMap.MarkerStyle({ | |
| width: 25, | |
| height: 35, | |
| anchor: {x: 16, y: 32}, | |
| src: 'https://mapapi.qq.com/web/lbs/javascriptGL/demo/img/end.png', | |
| }), | |
| }, | |
| geometries: [ | |
| { | |
| id: 'car', | |
| styleId: 'car-down', | |
| position: new TMap.LatLng(39.98481500648338, 116.30571126937866), | |
| }, | |
| { | |
| id: 'start', | |
| styleId: 'start', | |
| position: new TMap.LatLng(39.98481500648338, 116.30571126937866), | |
| }, | |
| { | |
| id: 'end', | |
| styleId: 'end', | |
| position: new TMap.LatLng(39.978813710266024, 116.31699800491333), | |
| }, | |
| ], | |
| }); | |
| } | |
| } |
4. 创建动画和标记
| // 暂停动画 | |
| pauseMove() { | |
| this.marker.pauseMove() | |
| }, | |
| // 停止动画 | |
| resumeMove() { | |
| this.marker.resumeMove() | |
| }, | |
| // 开始动画 | |
| startCar() { | |
| // 使用marker 移动接口, https://lbs.qq.com/webApi/javascriptGL/glDoc/glDocMarker | |
| //调用moveAlong动画 执行标记点动画开始 | |
| this.marker.moveAlong( | |
| { | |
| car: { | |
| path: this.path,//移动路径的坐标串 | |
| // duration:8000,//完成移动所需的时间,单位:毫秒 | |
| speed: 250, //speed为指定速度,正整数,单位:千米/小时 | |
| }, | |
| }, | |
| { | |
| autoRotation: true,//自动旋转 | |
| } | |
| ); | |
| //监听事件名 | |
| this.marker.on('moving', (e) => { | |
| var passedLatLngs = e.car && e.car.passedLatLngs; | |
| if (passedLatLngs) { | |
| // 使用路线擦除接口 eraseTo, https://lbs.qq.com/webApi/javascriptGL/glDoc/glDocVector | |
| this.polylineLayer.eraseTo( | |
| 'erasePath', | |
| passedLatLngs.length - 1, | |
| passedLatLngs[passedLatLngs.length - 1] | |
| ); | |
| } | |
| }); | |
| }, |
