使用Vue Baidu Map对百度地图实现输入框搜索定位
对新手很友好,尤其是第一次使用vue 百度地图的! 前端时间需要在页面的输入框输入地址,搜索并在百度地图上获取选定结果的坐标,前端使用了Vue + Element-ui,地图方面直接使用了封装好的百度地图vue组件-vue-baidu-map输入框使用自动完成的Input组件,在输入地址时不断更新地图搜索结果和地图当前定位。以下是demo代码<template><div cla

对新手很友好,尤其是第一次使用vue 百度地图的!
前端时间需要在页面的输入框输入地址,搜索并在百度地图上获取选定结果的坐标,前端使用了Vue + Element-ui,地图方面直接使用了封装好的百度地图vue组件-vue-baidu-map
输入框使用自动完成的Input组件,在输入地址时不断更新地图搜索结果和地图当前定位。
以下是demo代码
<template>
<div class="app-container">
<el-autocomplete
v-model="mapLocation.address"
:fetch-suggestions="querySearch"
placeholder="请输入详细地址"
style="width: 100%"
:trigger-on-focus="false"
@select="handleSelect"
/>
<div style="margin: 5px">
<baidu-map class="bm-view" :center="mapCenter" :zoom="mapZoom" :scroll-wheel-zoom="true" ak="baidu-ak" @ready="handlerBMap" />
</div>
</div>
</template>
<script>
import BaiduMap from 'vue-baidu-map/components/map/Map.vue'
export default {
name: 'BaiduMapDemo',
components: {
BaiduMap
},
data() {
return {
mapZoom: 15,
mapCenter: { lng: 0, lat: 0 },
mapLocation: {
address: undefined,
coordinate: undefined
}
}
},
methods: {
handlerBMap({ BMap, map }) {
this.BMap = BMap
this.map = map
if (this.mapLocation.coordinate && this.mapLocation.coordinate.lng) {
this.mapCenter.lng = this.mapLocation.coordinate.lng
this.mapCenter.lat = this.mapLocation.coordinate.lat
this.mapZoom = 15
map.addOverlay(new this.BMap.Marker(this.mapLocation.coordinate))
} else {
this.mapCenter.lng = 113.271429
this.mapCenter.lat = 23.135336
this.mapZoom = 10
}
},
querySearch(queryString, cb) {
var that = this
var myGeo = new this.BMap.Geocoder()
myGeo.getPoint(queryString, function(point) {
if (point) {
that.mapLocation.coordinate = point
that.makerCenter(point)
} else {
that.mapLocation.coordinate = null
}
}, this.locationCity)
var options = {
onSearchComplete: function(results) {
if (local.getStatus() === 0) {
// 判断状态是否正确
var s = []
for (var i = 0; i < results.getCurrentNumPois(); i++) {
var x = results.getPoi(i)
var item = { value: x.address + x.title, point: x.point }
s.push(item)
cb(s)
}
} else {
cb()
}
}
}
var local = new this.BMap.LocalSearch(this.map, options)
local.search(queryString)
},
handleSelect(item) {
var { point } = item
this.mapLocation.coordinate = point
this.makerCenter(point)
},
makerCenter(point) {
if (this.map) {
this.map.clearOverlays()
this.map.addOverlay(new this.BMap.Marker(point))
this.mapCenter.lng = point.lng
this.mapCenter.lat = point.lat
this.mapZoom = 15
}
}
}
}
</script>
<style>
.bm-view {
width: 100%;
height: 500px;
}
</style>
