vue实现搜索附近医院

2026-02-22 10:40:03VUE

实现思路

通过Vue结合高德地图API或百度地图API实现搜索附近医院功能。核心步骤包括获取用户位置、调用地图API搜索附近医院、展示结果。

获取用户位置

使用浏览器Geolocation API获取用户经纬度坐标。需注意https环境下才能正常调用。

navigator.geolocation.getCurrentPosition(
  position => {
    const { latitude, longitude } = position.coords
    this.userLocation = { lat: latitude, lng: longitude }
  },
  error => {
    console.error('获取位置失败:', error)
  }
)

调用地图API

以高德地图为例，需先引入AMap SDK：

<script src="https://webapi.amap.com/maps?v=2.0&key=你的高德Key"></script>

创建地图实例并搜索：

const map = new AMap.Map('map-container', {
  center: [this.userLocation.lng, this.userLocation.lat],
  zoom: 15
})

AMap.plugin('AMap.PlaceSearch', () => {
  const placeSearch = new AMap.PlaceSearch({
    type: '医院',
    pageSize: 20
  })
  placeSearch.searchNearBy('', [this.userLocation.lng, this.userLocation.lat], 5000, (status, result) => {
    this.hospitals = result.poiList.pois
  })
})

展示搜索结果

在Vue模板中渲染医院列表：

<div v-for="hospital in hospitals" :key="hospital.id">
  <h3>{{ hospital.name }}</h3>
  <p>{{ hospital.address }}</p>
  <p>距离：{{ hospital.distance }}米</p>
  <p>电话：{{ hospital.tel || '暂无' }}</p>
</div>

完整组件示例

<template>
  <div>
    <div id="map-container" style="width:100%;height:300px"></div>
    <div v-if="hospitals.length">
      <div v-for="hospital in hospitals" :key="hospital.id">
        <h3>{{ hospital.name }}</h3>
        <p>{{ hospital.address }}</p>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      userLocation: null,
      hospitals: []
    }
  },
  mounted() {
    this.initMap()
  },
  methods: {
    initMap() {
      if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(
          position => {
            this.userLocation = {
              lat: position.coords.latitude,
              lng: position.coords.longitude
            }
            this.loadAMap()
          },
          error => {
            console.error('获取位置失败:', error)
          }
        )
      }
    },
    loadAMap() {
      const script = document.createElement('script')
      script.src = `https://webapi.amap.com/maps?v=2.0&key=你的高德Key`
      script.onload = () => this.searchHospitals()
      document.head.appendChild(script)
    },
    searchHospitals() {
      const map = new AMap.Map('map-container', {
        center: [this.userLocation.lng, this.userLocation.lat],
        zoom: 15
      })

      AMap.plugin('AMap.PlaceSearch', () => {
        const placeSearch = new AMap.PlaceSearch({
          type: '医院',
          pageSize: 20
        })
        placeSearch.searchNearBy('', [this.userLocation.lng, this.userLocation.lat], 5000, (status, result) => {
          this.hospitals = result.poiList.pois
        })
      })
    }
  }
}
</script>
