這篇文章主要介紹了vue + echarts實(shí)現(xiàn)中國地圖省份點(diǎn)擊聯(lián)動,需要的朋友可以參考下

引入echarts

npm下載

npm install echarts

cdn引入

<script
  type="text/javascript"
  src="https://cdn.jsdelivr.net/npm/echarts/dist/echarts.min.js"
></script>

引入中國地圖china.js

<script
  type="text/javascript"
  src="https://cdn.jsdelivr.net/npm/echarts/map/js/china.js"
></script>

配置中國地圖

定義一個div來作為地圖的載體

render: function(createElement) {
    return createElement("div", {
      attrs: {
        id: "main",
      },
      style: {
        height: "450px",
        width:'600px',
        margin: 'auto'
      },
    });
},

設(shè)置各省份的值

定義省份數(shù)據(jù)

data() {
    return {
      dataList: [
        { name: "南海諸島" },
        { ename: "beijing", name: "北京"},
        { ename: "tianjin", name: "天津" },
        { ename: "shanghai", name: "上海" },
        { ename: "chongqing", name: "重慶" },
        { ename: "hebei", name: "河北" },
        { ename: "henan", name: "河南"},
        { ename: "yunnan", name: "云南" },
        { ename: "liaoning", name: "遼寧" },
        { ename: "heilongjiang", name: "黑龍江" },
        { ename: "hunan", name: "湖南"},
        { ename: "anhui", name: "安徽" },
        { ename: "shandong", name: "山東" },
        { ename: "xinjiang", name: "新疆" },
        { ename: "jiangsu", name: "江蘇" },
        { ename: "zhejiang", name: "浙江" },
        { ename: "jiangxi", name: "江西" },
        { ename: "hubei", name: "湖北" },
        { ename: "guangxi", name: "廣西"},
        { ename: "gansu", name: "甘肅" },
        { ename: "shanxi", name: "山西" },
        { ename: "neimenggu", name: "內(nèi)蒙古" },
        { ename: "shanxi1", name: "陜西" },
        { ename: "jilin", name: "吉林" },
        { ename: "fujian", name: "福建" },
        { ename: "guizhou", name: "貴州" },
        { ename: "guangdong", name: "廣東" },
        { ename: "qinghai", name: "青海" },
        { ename: "xizang", name: "西藏" },
        { ename: "sichuan", name: "四川" },
        { ename: "ningxia", name: "寧夏" },
        { ename: "hainan", name: "海南" },
        { name: "臺灣"},
        { ename: "xianggang", name: "香港" },
        { ename: "aomen", name: "澳門" },
      ],
    };
  },

隨機(jī)給各省份賦值

let dataList = this.dataList;
for(let i = 0; i < dataList.length; i++){
    dataList[i].value = Math.ceil(Math.random() * 1000 - 1);
}

鼠標(biāo)懸浮展示

option中的tooltip可以設(shè)置鼠標(biāo)懸浮在省份上的數(shù)據(jù)顯示

// 鼠標(biāo)懸浮提示框
series: [
  {
    name: "省份",
    type: "map",
    geoIndex: 0,
    data: this.dataList,
  },
],
tooltip: {
  //數(shù)據(jù)格式化
  formatter: function(params, callback) {
    return (
      params.seriesName + "<br />" + params.name + "：" + params.value
    );
  },
},

如下圖為鼠標(biāo)懸浮在廣東上的數(shù)據(jù)提示??

visualMap圖注配置數(shù)值映射

在min和max中，數(shù)值越大，區(qū)域顏色越深。

visualMap: {
    min: 0, //最小值
    max: 1000, //最大值
    left: "left", //位于地圖左邊
    top: "bottom",//位于地圖下方
    text: ["高", "低"], //取值范圍的文字
    inRange: {
        color: ["#e0ffff", "blue"], //取值范圍的顏色
    },
    show: true, //圖注
},

geo地圖繪制

geo: {
  map: "china", //引入地圖數(shù)據(jù)
  roam: false, //不開啟縮放和平移
  zoom: 1, //視角縮放比例
  label: {
    normal: {
      show: true,
      fontSize: "10",
      color: "rgba(0,0,0,0.7)",
    },
  },
  itemStyle: {
    normal: {
      borderColor: "rgba(0, 0, 0, 0.2)",
    },
    emphasis: { //高亮的顯示設(shè)置
      areaColor: "skyblue", //鼠標(biāo)選擇區(qū)域顏色
      shadowOffsetX: 0,
      shadowOffsetY: 0,
      shadowBlur: 20,
      borderWidth: 0,
      shadowColor: "rgba(0, 0, 0, 0.5)",
    },
  },
},

省份區(qū)域點(diǎn)擊事件

可以通過該點(diǎn)擊事件實(shí)現(xiàn)省份下鉆聯(lián)動，點(diǎn)擊跳轉(zhuǎn)到省級地圖頁面，省級地圖頁面根據(jù)傳入?yún)?shù)渲染不同的省份地圖數(shù)據(jù)即可，具體實(shí)現(xiàn)后面會講到。

myChart.on("click", function(params) {
    if(!params.data.ename){
      alert('暫無' + params.name + '地圖數(shù)據(jù)');
      return;
    }
    _this.$router.push({
      path: "/province",
      query: { provinceName: params.data.ename, province: params.name },
    });
});

配置省級地圖

前面通過中國地圖的省份區(qū)域點(diǎn)擊事件跳轉(zhuǎn)到省級地圖頁面，并傳遞對應(yīng)參數(shù)，在省級地圖頁面可以根據(jù)參入?yún)?shù)來渲染不同的地圖數(shù)據(jù)。

引入省份地圖資源

如下圖，省份地圖資源的js版數(shù)據(jù)和json版數(shù)據(jù)我都已經(jīng)放在源碼中，這里我使用的是json版數(shù)據(jù)，有需要的同學(xué)可以直接去下載。

編寫簡單頁面

返回按鈕+省級地圖。

<div>
    <div @click="goBack()">返回</div>
    <div :id="id" class="o-echarts"></div>
</div>

地圖配置

與前面中國地圖的配置規(guī)則是一樣的，按需配置即可

option: {
    title: {
      text: '',
      top: '8%',
      left: '8%',
      textStyle: {
        fontSize: 14,

    },

      // 數(shù)據(jù)格式化
      formatter: function (params, callback) {

      }
    },
    legend: {
      orient: 'vertical',
      top: '9%',
      left: '5%',
      icon: 'circle',
      data: [],
      selectedMode: 'single',
      selected: {},
      itemWidth: 12,
      itemHeight: 12,

      textStyle: {

        fontSize: 14,
        fontWeight: 300,
        padding: [0, 0, 0, 15]
      }
    },
    visualMap: {
      min: 0,
      max: 500,
      left: 'left',
      top: 'bottom',
      text: ['高', '低'], // 取值范圍的文字
      inRange: {
        color: ['#e0ffff', 'blue'] // 取值范圍的顏色
      },
      show: true // 圖注
    },
    geo: {
      map: '',
      roam: false, // 不開啟縮放和平移
      zoom: 0.6, // 視角縮放比例
      label: {
        normal: {
          show: true,
          fontSize: 10,
          color: '#000'
        },
        emphasis: {
          show: true,
          color: 'blue',
        }
      },
      itemStyle: {
        normal: {
          borderColor: 'rgba(0, 0, 0, 0.2)'
        },
        emphasis: {
          areaColor: 'skyblue', // 鼠標(biāo)選擇區(qū)域顏色
          shadowOffsetX: 0,
          shadowOffsetY: 0,
          shadowBlur: 20,
          borderWidth: 0,

      },

      right: '5%',
      top: '5%',
      bottom: '5%'
    },
    series: [
      {
        name: '年度總項目數(shù)據(jù)查詢',
        type: 'map',
        geoIndex: 0, // 不可缺少，否則無tooltip 指示效果
        data: []
      }
    ],
    provinceJSON: {},
    provinceName: ''
  }

根據(jù)參數(shù)配置不同地圖數(shù)據(jù)

const provinceName = this.$route.query.provinceName
const province = this.$route.query.province
this.provinceName = provinceName
this.provinceJSON = require('../../utils/省份數(shù)據(jù)/json(省份)/' + provinceName)
this.option.geo.map = province
this.echartObj = echarts.init(document.getElementById(this.id))
echarts.registerMap(province, this.provinceJSON)
this.echartObj.setOption(this.option);
window.addEventListener('resize', () => {
  if (this.echartObj && this.echartObj.resize) {
    this.echartObj.resize()
  }
})
