*最近在做一个需要有地图下钻的项目，考虑用ECharts实现，需要每个省的数据太大，所以此处谨以广东省为例，其他数据可自己添加，先上效果图*

*用的是Vue1.0先看代码结构：*

因为ECharts3不再内置地图数据，需要自己下载所需的地图ECharts地图下载,index.js将所有的地图文件引进来

再看chinaOption.js文件,这是一个混合文件，将地图的设置全部写在这文件

export default{
  data(){
    return{
      provinceList: ["河北","山西","内蒙古","辽宁","吉林","黑龙江","江苏","浙江","安徽","福建","江西","山东","河南","湖北","湖南","广东","广西","海南","四川","贵州","云南","西藏","陕西","甘肃","青海","宁夏","新疆","北京","天津","上海","重庆","香港","澳门","台湾",],
      cityList:["广州市","深圳市","珠海市","汕头市","韶关市","佛山市","江门市","湛江市","茂名市","肇庆市","梅洲市","汕尾市","河源市","阳江市","清远市","东莞市","中山市","潮州市","揭阳市","云浮市","惠州市","梅州市"],
      option:{
          title: {
              text: '全国分布图',
              left: 'left'
          },
          tooltip: {
              trigger: 'item'
          },
          legend: {
              orient: 'vertical',
              left: 'left',
              top:'bottom',
              data:['企业数']
          },
          visualMap: {
              min: 0,
              max: 2500,
              left: 'left',
              top: 'bottom',
              text: ['高','低'],
              calculable: true,
              show:false,
          },
          series: [{
                  name: '企业数',
                  type: 'map',
                  mapType: 'china',
                  roam: false,
                  width:'100%',
                  label: {
                      normal: {show: true},
                      emphasis: {show: true}
                  },
                  data:[]
              },
          ]
      }
    }
  },
  methods:{
    randomData() {
        return Math.round(Math.random()*1000);
    },
    //为每个省市虚构数据
    setData(){
        this.provinceList.forEach((item)=>{
          this.option.series[0].data.push({name:item,value:this.randomData()})
        })
        this.cityList.forEach((item)=>{
          this.option.series[0].data.push({name:item,value:this.randomData()})
        })
    }
  },
  ready(){
    this.setData()
  }
}

最后是index.vue文件，用了jq,ivew和ES6,

<template>
<div id="chinaMap">
    <!-- iview组件，也可以用其他的图标 -->
    <Icon type="arrow-shrink" size="40" v-if="option.series[0].mapType!='china'" @click="toChina"></Icon>
    <div class="map" v-el:map></div>
</div>
</template>
<script>
import echarts from 'echarts/lib/echarts';
import 'echarts/lib/chart/map';
import '../../assets/themes/shine.js'
import '../../assets/maps/index.js'
import chinaOption from './chinaOption.js'
export default {
    mixins: [chinaOption],
    data() {
        return {
            myChart: '',
        }
    },
    ready() {
        this.myChart = echarts.init(this.$els.map, 'shine');
        this.myChart.setOption(this.option);
        this.myChart.on("click", this.chartClick);
    },
    methods: {
        chartClick(param) {
            this.myChart.setOption(this.option, false);
            //防止地图继续下钻，若需要继续下钻可以注释掉，敲黑板，此处是同一个元素，不是冒泡，
            if (this.provinceList.indexOf(param.name) == -1) return
            this.option.title.text =  param.name + "分布图"
            Object.assign(this.option.series[0], {
                mapType: param.name,
                width: '70%',
            })
            this.myChart.setOption(this.option, true);
        },
        toChina(){
          this.myChart.setOption(this.option, false);
          this.option.title.text = "全国分布图"
          Object.assign(this.option.series[0], {
              mapType: 'china',
              width: '100%',
          })
          this.myChart.setOption(this.option, true);
        }
    }
}
</script>

<style lang="sass">
#chinaMap {
    position:relative;
    .map {
        width: 500px;
        height: 500px;
    }
    .ivu-icon {
      cursor:pointer;
        position: absolute;
        left: 480px;
        top:20px;
        z-index:2;
    }
}
</style>
