用vue去实现一个地图线路

Vue 可以通过引入百度地图 API 和相关组件来实现地图线路,具体步骤如下:
1. 在 `index.html` 中引入百度地图 API:
```html
<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=百度地图API密钥"></script>
```
2. 在 Vue 组件中引入 `BMap` 和 `BMap.RouteSearch` 组件:
```javascript
import BMap from 'BMap';
import BMapRouteSearch from 'BMap.RouteSearch';
```
3. 在 `mounted` 生命周期中初始化地图和路线搜索对象:
```javascript
mounted() {
const map = new BMap.Map('map-container');
const routeSearch = new BMap.RouteSearch();
this.map = map;
this.routeSearch = routeSearch;
}
```
4. 在 `methods` 中编写路线搜索方法,将搜索结果存储在 `routes` 数组中:
```javascript
searchRoute() {
const startPoint = new BMap.Point(起点经度, 起点纬度);
const endPoint = new BMap.Point(终点经度, 终点纬度);
this.routeSearch.search(startPoint, endPoint, {
onSearchComplete: (result) => {
const routes = [];
const plan = result.getPlan(0);
for (let i = 0; i < plan.getNumRoutes(); i++) {
const route = plan.getRoute(i);
const path = route.getPath();
const polyline = new BMap.Polyline(path, {
strokeColor: 'blue',
strokeWeight: 6,
strokeOpacity: 0.5
});
routes.push(polyline);
this.map.addOverlay(polyline);
}
this.routes = routes;
}
});
}
```
5. 在模板中渲染地图和路线:
```html
<template>
<div>
<div id="map-container"></div>
<button @click="searchRoute">搜索路线</button>
</div>
</template>
```
完整代码示例:
```javascript
<template>
<div>
<div id="map-container"></div>
<button @click="searchRoute">搜索路线</button>
</div>
</template>
<script>
import BMap from 'BMap';
import BMapRouteSearch from 'BMap.RouteSearch';
export default {
data() {
return {
map: null,
routeSearch: null,
routes: []
};
},
mounted() {
const map = new BMap.Map('map-container');
const routeSearch = new BMap.RouteSearch();
this.map = map;
this.routeSearch = routeSearch;
},
methods: {
searchRoute() {
const startPoint = new BMap.Point(起点经度, 起点纬度);
const endPoint = new BMap.Point(终点经度, 终点纬度);
this.routeSearch.search(startPoint, endPoint, {
onSearchComplete: (result) => {
const routes = [];
const plan = result.getPlan(0);
for (let i = 0; i < plan.getNumRoutes(); i++) {
const route = plan.getRoute(i);
const path = route.getPath();
const polyline = new BMap.Polyline(path, {
strokeColor: 'blue',
strokeWeight: 6,
strokeOpacity: 0.5
});
routes.push(polyline);
this.map.addOverlay(polyline);
}
this.routes = routes;
}
});
}
}
};
</script>
```
