vue项目实现百度离线地图开发

vue项目结合百度离线地图开发

百度地图(布标记点,标记点聚合,标记点详情,标记点轨迹)

注意:标记点和详情弹框以及点的轨迹图没有展示出来,没数据没办法!!!!!

第一步

首先下载好 百度离线地图包,解压好的文件放在指定目录下public。

第二步

然后在public目录下的index.html引入离线地图所需的文件。

第三步

接着就是地图展示的主要代码

<template><div class="app-container"><el-row :gutter="24"><el-col :xs="24" :sm="24" :md="24" :lg="24" :xl="24"><div class="head-container"><divid="map"class="baiduMap"></div><el-tooltip content="刷新地图" placement="bottom"><el-button class="refresh" type="primary" icon="el-icon-refresh" size="mini" circle @click="onClickRefreshMap"></el-button></el-tooltip></div></el-col></el-row></div></template><script>export default {name: "MapShows",components: {},data() {return {markerArr: [],orgId: "",map: null,dataListShow: false,polyline: null,formInline: {planCode: "",workTaskName: "",},centrePoint: []};},created() {},mounted() {this.getMapZfysByOrgId();},methods: {getMapZfysByOrgId() {this.$api.getMxxxxxxxrgIds().then((response) => {this.markerArr = response;this.initMap();});},initMap() {let self = this;//初始化坐标点信息this.$api.getAllBxxxxxxxionaryName("MapSetting").then((response) => {// 获取系统地图参数设置var markersArr = [];const mapSetting = response.items;let defaultCenterX = 87.36,defaultCenterY = 43.45,defaultLevel = 12,maxLevel = 16,minLevel = 4;mapSetting.forEach((m) => {if (m.label == "默认中心点" && m.value) {let point = m.value.split(";");defaultCenterX = parseFloat(point[0]);defaultCenterY = parseFloat(point[1]);} else if (m.label == "默认层级" && m.value) {defaultLevel = parseInt(m.value);} else if (m.label == "最大层级" && m.value) {maxLevel = parseInt(m.value);} else if (m.label == "最小层级" && m.value) {minLevel = parseInt(m.value);}});this.$nextTick(() => {self.map = new BMap.Map("map", {mimZoom: minLevel,maxZoom: maxLevel,});

第四步

注意事项:如果内网项目地图展示要提前下载好地图瓦片数据,还有就是别把瓦片数据也放在public里,因为vue项目在build打包的时候也会将其打包进去,就会造成打包非常慢还有包非常之大,建议内网项目把瓦片数据存放在项目外,瓦片做nginx代理链接: 瓦片下载器,具体存放在哪里后台实现。

这就是前端百度离线地图的实现方法,希望能帮到相同需求的人,同时哪里不对地方也希望多多指点!
