请添加图片描述

一、引入amap地图库 - public/index.html

<script type="text/javascript">window._AMapSecurityConfig = {securityJsCode: '地图密钥' }</script><scripttype="text/javascript"src="https://webapi.amap.com/maps?v=1.4.8&key=111111111111111111111111"></script>

二、组件 - DzvScatterMap

<template><div class="container-box"><div id="container"></div></div>
</template>
<script>
import { containerType, getLocation } from '@/utils/alipay'
import locationImg from '@/assets/images/location.png'const { AMap } = windowconst iconSize = 56
const defaultZoom = 12export default {name: 'DzvScatterMap',props: {lngLat: {type: Array,default: () => []},// 点位列表list: {type: Array,default: () => []},// 样式列表styles: {type: Array,default: () => []}},data() {return {map: null,cluster: null,mass: null,styleList: []}},watch: {lngLat: function(value) {if (value && value.length > 0) {this.initAMap()}},list: {deep: true,handler: function(newVal) {if (this.map) {this.markerMyPosition(this.lngLat)}}},styles: {deep: true,handler: function(newVal) {this.styleList = newVal?.map(it => ({...it,url: it?.src,anchor: new AMap.Pixel(6, 6),size: new AMap.Size(iconSize, 56),zIndex: 3}))}}},created() {},mounted() {this.initAMap()},methods: {// 初始化地图initAMap() {this.map = new AMap.Map('container', {zoom: defaultZoom, // 级别resizeEnable: true,center: [113.67621, 34.74499], // 默认中心点坐标viewMode: '2D' // 使用2D视图,使用3D在amap2.0中会旋转})this.markerMyPosition(this.lngLat)},// 标记自己的位置markerMyPosition(lngLat) {if (lngLat && lngLat.length > 0) {if (this.locationMarker) {this.map.remove(this.locationMarker)}this.locationMarker = new AMap.Marker({offset: new AMap.Pixel(-10, -10),position: new AMap.LngLat(lngLat[0], lngLat[1]),zoom: 13,content: `<div style="background-size: 100% 100%; height: 30px; width: 30px; background-image:url(${locationImg});"></div>`})if (this.map) {this.map.add(this.locationMarker) // 添加位置markerthis.map.setCenter(lngLat) // 设置中心this.map.setZoom(defaultZoom) // 重置缩放this.panBy() // 设置地图平移量，将marker移到中心}}// 地图加载完成后，进行撒点this.asyncMarker()},// 地图的平移panBy() {const refList = document.getElementById('refList')const height = refList?.offsetHeightif (height > 50) {// 地图中心点平移this.map.panTo(this.lngLat)// 像素值平移this.map.panBy(0, -height / 2)}},// 撒点getMarkerList(allPoints = {}, currentType = '') {// 洒点之前清除上次的洒点if (this.mass) this.mass.clear()if (this.list) {const serviceHall = this.list.map(item => {return {...item,lnglat: [item.siteCoordinateY, item.siteCoordinateX],style: item.typeId}})this.mass = new AMap.MassMarks(serviceHall, {opacity: 0.8,zIndex: 111,cursor: 'pointer',style: this.styleList})this.mass.on('click', this.markerClick)this.mass.setMap(this.map)this.$forceUpdate()}},// 类型和全部定位数据修改的时候进行延迟撒点，展示列表中的loading效果asyncMarker() {const _this = thissetTimeout(() => {const { allPoints, currentType } = _this_this.getMarkerList(allPoints, currentType)}, 5)},// 点击事件markerClick(e) {// const curentPoint = e.target.getExtData() || {}const currentPoint = e.data || {}this.$emit('changePoint', currentPoint)},// 获取当前位置async location() {if (containerType() === 'xcx' || containerType() === 'wechat') {// this.$emit('changeLngLat', this.lngLat)this.markerMyPosition(this.lngLat)} else {const lngLat = await getLocation()// this.$emit('changeLngLat', lngLat)this.markerMyPosition(lngLat)}}}
}
</script>
<style lang="scss" scoped>
.container-box {padding: 0px;margin: 0px;width: 100vw;height: calc(100vh - 50px);position: relative;
}
#container {padding: 0px;margin: 0px;width: 100%;height: 100%;position: absolute;
}
.location-icon {width: 40px;height: 40px;background: $white;border-radius: 10px;display: flex;justify-content: center;align-items: center;position: absolute;z-index: 20;right: 10px;top: 10px;
}
h3 {position: absolute;left: 10px;z-index: 2;color: white;
}
::v-deep {.amap-logo {z-index: -1;}.amap-copyright {z-index: -1;}
}
</style>

三、使用

2.1.home/index.vue

<template><div><HomePickers:types="types"@updateInfo="updateInfo":class="{ 'home-pickers': true, 'fade-out-picker': fadeOutPicker, 'fade-in-picker': fadeInPicker }"/><DzvScatterMapref="map":isInit="isInit":lngLat="lngLat":styles="styles":list="itemList"@changePoint="changePoint"><div id="container" slot="container"></div></DzvScatterMap><HomeBtns @btn="btnClick" ref="refList" id="refList" /><HomeSearch :class="{ 'home-search': true, 'fade-out-search': fadeOutSearch, 'fade-in-search': fadeInSearch }" /><HomeModal v-if="showModal" @changeShow="changeShow" :item="currentPoint" /></div>

}
</script>
<style lang="scss" scoped>
.home-pickers {width: 100%;position: absolute;top: 0;z-index: 1000;
}
.home-search {width: 100%;position: absolute;bottom: 0;z-index: 999;
}
.fade-out-picker {animation: fadeOutPicker 1s ease forwards;
