vue3.0引入百度地图并标记点的实现代码

首先新建一个js,主要用来引入百度地图的js,代码如下:

export function baiduMap() { return new Promise(function(resolve, reject) { window.baiduMap = function() { resolve() } var script2 = document.createElement('script') script2.type = 'text/javascript' script2.src = `http://api.map.baidu.com/library/SearchInfoWindow/1.5/src/SearchInfoWindow_min.js` var link = document.createElement('link') link.rel = 'stylesheet' link.href = `http://api.map.baidu.com/library/SearchInfoWindow/1.5/src/SearchInfoWindow_min.css` document.head.appendChild(link) document.head.appendChild(script2) var script = document.createElement('script') script.type = 'text/javascript' script.src = `http://api.map.baidu.com/api?v=3.0&ak=你的ak&callback=baiduMap` script.onerror = reject document.head.appendChild(script) }) }

获取生成密匙: ak密匙(百度地图)

其次,创建baidu-map.vue,代码如下:

<template> <el-dialog title="门店地图分布" v-model="open" width="70%" draggable> <div id="map" :style="{height:mapHeight}"> <div id="allmap" ref="allmap" ></div> </div> </el-dialog> </template> <script setup name="BaiduMap"> import {baiduMap} from '@/api/post/baiduMap' import {getLineShopMap} from '@/api/post/line' import {nextTick} from "vue"; const mapHeight = ref('70vh') const open = ref(false) const allmap = ref(null) function map(id) { open.value = true getLineShopMap(id).then(res => { var markerArr = [] var data = res.data for (var i = 0; i < data.length; i++) { var point = data[i].lng + "," + data[i].lat; var shop = '{ title: "' + data[i].shopname + '",areaname: "' + data[i].name + '", point: "' + point + '", receiver: "' + data[i].receiver + '", mobile: "' + data[i].mobile + '" }'; var shopobj = eval('(' + shop + ')'); markerArr.push(shopobj); } nextTick(res => { baiduMap().then(thatMap => { // 创建地图实例 var map = new BMap.Map("map"); var point = new BMap.Point(113.312213, 23.147267); //地图中心点,广州市 map.centerAndZoom(point, 13); // 初始化地图,设置中心点坐标和地图级别。 map.enableScrollWheelZoom(true); //启用滚轮放大缩小 //地图、卫星、混合模式切换 map.addControl(new BMap.MapTypeControl({mapTypes: [BMAP_NORMAL_MAP, BMAP_SATELLITE_MAP, BMAP_HYBRID_MAP]})); //向地图中添加缩放控件 var ctrlNav = new window.BMap.NavigationControl({ anchor: BMAP_ANCHOR_TOP_LEFT, type: BMAP_NAVIGATION_CONTROL_LARGE }); map.addControl(ctrlNav); //向地图中添加缩略图控件 var ctrlOve = new window.BMap.OverviewMapControl({ anchor: BMAP_ANCHOR_BOTTOM_RIGHT, isOpen: 1 }); map.addControl(ctrlOve); //向地图中添加比例尺控件 var ctrlSca = new window.BMap.ScaleControl({ anchor: BMAP_ANCHOR_BOTTOM_LEFT }); map.addControl(ctrlSca); var point = new Array(); //存放标注点经纬信息的数组 var marker = new Array(); //存放标注点对象的数组 var info = new Array(); //存放提示信息窗口对象的数组 var searchInfoWindow = new Array();//存放检索信息窗口对象的数组 for (var i = 0; i < markerArr.length; i++) { var p0 = markerArr[i].point.split(",")[0]; // var p1 = markerArr[i].point.split(",")[1]; //按照原数组的point格式将地图点坐标的经纬度分别提出来 point[i] = new window.BMap.Point(p0, p1); //循环生成新的地图点 marker[i] = new window.BMap.Marker(point[i]); //按照地图点坐标生成标记 map.addOverlay(marker[i]); marker[i].setAnimation(BMAP_ANIMATION_BOUNCE); //跳动的动画 //显示marker的title,marker多的话可以注释掉 var label = new window.BMap.Label(markerArr[i].title, {offset: new window.BMap.Size(20, -10)}); marker[i].setLabel(label); // 创建信息窗口对象 receiver: "'+data[i].receiver+'", mobile: info[i] = "<p style='font-size:14px;line-height:20px'>" + "</br>门店名称:" + markerArr[i].title + "</br>所在区域:" + markerArr[i].areaname + "</br>接收人:" + markerArr[i].receiver + "</br> 门店电话:" + markerArr[i].mobile + "</br></p>"; //创建百度样式检索信息窗口对象 searchInfoWindow[i] = new BMapLib.SearchInfoWindow(map, info[i], { title: markerArr[i].title, //标题 width: 290, //宽度 // height : 40, //高度 panel: "panel", //检索结果面板 enableAutoPan: true, //自动平移 searchTypes: [ BMAPLIB_TAB_SEARCH, //周边检索 // BMAPLIB_TAB_TO_HERE, //到这里去 // BMAPLIB_TAB_FROM_HERE //从这里出发 ] }); //添加点击事件 marker[i].addEventListener("click", (function (k) { // js 闭包 return function () { //将被点击marker置为中心 // map.centerAndZoom(point[k], 13); // console.log(searchInfoWindow[k]) //在marker上打开检索信息窗口 searchInfoWindow[k].open(marker[k]); } })(i) ); } }); }) }) } defineExpose({ map }) </script> <style> #allmap { height: 100%; overflow: hidden; } </style>

最后,在你需要用到的界面引用

引用界面的script的代码

import BaiduMap from "./baidu-map"; const mapRef = ref(null); /** * 查看地图 * @param selection */ function openMap() { mapRef.value.map(form.value.id) }

最终效果
