vue地图轨迹实现
实现Vue地图轨迹的基本步骤
安装地图库,如高德地图或百度地图的Vue组件。以高德地图为例,通过npm安装:
npm install @amap/amap-jsapi-loader --save
在Vue组件中引入并初始化地图:
import AMapLoader from '@amap/amap-jsapi-loader';
export default {
data() {
return {
map: null,
path: [
[116.478935, 39.997761],
[116.478939, 39.997825]
]
}
},
mounted() {
this.initMap();
},
methods: {
initMap() {
AMapLoader.load({
key: '你的高德地图Key',
version: '2.0'
}).then((AMap) => {
this.map = new AMap.Map('mapContainer', {
viewMode: '2D',
zoom: 13,
center: [116.397428, 39.90923]
});
this.drawPolyline();
});
}
}
}
绘制轨迹线的方法
使用高德地图的Polyline类绘制轨迹线:
drawPolyline() {
const polyline = new AMap.Polyline({
path: this.path,
isOutline: true,
outlineColor: '#ffeeff',
borderWeight: 1,
strokeColor: '#3366FF',
strokeOpacity: 1,
strokeWeight: 6,
strokeStyle: 'solid'
});
this.map.add(polyline);
this.map.setFitView([polyline]);
}
动态更新轨迹的实现
通过定时器模拟实时轨迹更新:
startTracking() {
let index = 0;
this.timer = setInterval(() => {
if (index < this.path.length) {
this.path.push([
this.path[index][0] + Math.random() * 0.01,
this.path[index][1] + Math.random() * 0.01
]);
this.drawPolyline();
index++;
} else {
clearInterval(this.timer);
}
}, 1000);
}
轨迹动画效果的添加
使用高德地图的moveAlong方法实现轨迹动画:
addMovingMarker() {
const marker = new AMap.Marker({
map: this.map,
position: this.path[0],
icon: 'https://webapi.amap.com/theme/v1.3/markers/n/mark_b.png'
});
marker.moveAlong(this.path, {
duration: 1000 * this.path.length,
autoRotation: true
});
}
轨迹点的标记处理
在关键位置添加标记点:
addMarkers() {
this.path.forEach((point, index) => {
new AMap.Marker({
position: point,
content: `<div class="marker">${index + 1}</div>`,
offset: new AMap.Pixel(-10, -10)
}).addTo(this.map);
});
}
样式优化建议
在组件的style部分添加轨迹线样式:
#mapContainer {
width: 100%;
height: 500px;
}
.marker {
background: #4CAF50;
color: white;
border-radius: 50%;
width: 20px;
height: 20px;
text-align: center;
line-height: 20px;
}
