准备工作

• 高德地图申请key
• 安装Echarts 中国地图

高德地图

• 官方API：点我进入
• 创建AMap.js

export default function MapLoader () {return new Promise((resolve, reject) => {if (window.AMap) {resolve(window.AMap)} else {// 动态创建script标签var script = document.createElement('script')script.type = 'text/javascript'script.async = truescript.src = 'https://webapi.amap.com/maps?v=1.4.9&callback=initAMap&key=Key&plugin=AMap.DistrictSearch,AMap.Circle,AMap.LngLat,AMap.Polyline,AMap.LngLat,AMap.Text,AMap.Geocoder';// plugin后的是需要的插件script.onerror = rejectdocument.head.appendChild(script)}window.initAMap = () => {resolve(window.AMap)}})
}

Echarts 中国地图

• 安装Echarts

npm install echarts -S
复制代码

开始使用

• 创建组件 distribution.vue
• 写入Echarts 需要的DOM

    <div class="main_wrap" ><div ref="main" class="main_box"></div><div class="Rankingtips"><p>分布指数</p><div class="color_tip"><span style="float: left">高</span><div></div><div></div><div></div><div></div><div></div><span style="margin-left: 5px">低</span></div></div></div>
复制代码

• 写入高德地图需要的DOM

    <div class="main_wrap" v-show="activeState2"><div id="container" style="height: 100%"></div></div>
复制代码

• 引入高德地图、Echarts

    import 'echarts/map/js/china'; //中国地图jsimport MapLoader from 'components/home/AMap'
复制代码

• Echarts方法

generateEcharts() {var echarts = require('echarts');var myChart = echarts.init(this.$refs.main);  // 基于准备好的dom，初始化echarts实例this.$ajax.get(this.HOST + "/redesign/home/findEnterpriseistribution").then( (res) => {// 数据格式// [//   {name: "北京", value: 3, ranking: 1},//   {name: "河北", value: 2, ranking: 2},//   {name: "上海", value: 1, ranking: 3},//   {name: "广东", value: 1, ranking: 4}//   ...// ]this.homebution = res.data.resultObject;var data = [];for (let i = 0; i < res.data.resultObject.length; i++) {this.homebutionnum += res.data.resultObject[i].value;let classnum = ""// 排名显示样式if(res.data.resultObject[i].ranking == 1) { classnum = "#1669e6"}else if(res.data.resultObject[i].ranking > 1 && res.data.resultObject[i].ranking <= 4) {classnum = "#31a4ed"}else if(res.data.resultObject[i].ranking > 4 && res.data.resultObject[i].ranking <= 10) {classnum = '#2cccfd'}else if(res.data.resultObject[i].ranking > 10 && res.data.resultObject[i].ranking <= 20) {classnum = '#7fe2fd'}else {classnum = '#d9f4fe'}data.push({name: res.data.resultObject[i].name,itemStyle: {normal: {areaColor: classnum,// borderWidth: 2},emphasis: {//高亮状态下的多边形和标签样式borderWidth: 1,// borderColor: '#d9f4fe',areaColor: '#d9f4fe',label: {shadowColor: '#d9f4fe', //默认透明shadowBlur: 10,show: true,textStyle: {fontSize: 12,color: '#3db77f'}}}},label: {normal: {show: true,textStyle: {fontSize: 12,color: '#0d6fb8'}},emphasis: {show: true,color: '#3db77f'}},value: res.data.resultObject[i].value ? res.data.resultObject[i].value: "",ranking: res.data.resultObject[i].ranking ? res.data.resultObject[i].ranking: ""})}// 准备提示数据var option = {tooltip: {formatter:  (params) => {var info = "";if(params.data) {info = `<div style="width: 60px;height: 60px"><p style="font-size:12px">${ params.name }</p><p style="font-size:12px">${ params.data.value }</p><p style="font-size:12px">排名：${ params.data.ranking }</p></div>`}else {info = `<div style="width: 60px;height: 60px"><p style="font-size:12px">${ params.name }</p></div>`}return info;},backgroundColor: "rgba(0,0,0,.6)",//提示标签背景颜色textStyle: { color: "#fff" } //提示标签字体颜色},//配置属性series: [{  name: '数据',  type: 'map',  mapType: 'china',   roam: true,  label: {  normal: {  show: false  //省份名称  },  emphasis: { show: false  }  },  data: data  //数据}],};//使用制定的配置项和数据显示图表myChart.setOption(option);})
