VUE 记一次高德地图和Echarts（中国地图）

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 = true
        script.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 = reject
        document.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js
    import 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 = [];

            let classnum = ""

            if(res.data.resultObject[i].ranking == 1) {
