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]
);
}
});
