梳理清楚的echarts地图下钻和标点信息组件

效果图

说明

默认数据没有就是全国地图，
$bus.off("onresize")是地图容器变化刷新地图适配的，可以你们自己写
getEchartsFontSize是适配字体大小的，getEchartsFontSize(0.12) === 12
mapScatter是base64图片就是图上那个标点的底图
GetMapGeoJson是获取地图json的，这里的是我公司的，可以用阿里云的代替
还有不明白的可以看是之前的文章，echart5.x地图下钻和地图标点(vue3+ts)

// 地图2--阿里云地图
function GetMapGeoJson2(cityCN: string, citylevel: string) {var uploadedDataURL = "";if (citylevel == "china") {//全国地图return "https://geo.datav.aliyun.com/areas_v3/bound/100000_full.json";}if (citylevel != "district" && (cityCN + "").substring(4) != "00")citylevel = "district";if (citylevel == "district") {uploadedDataURL ="https://geo.datav.aliyun.com/areas_v3/bound/" + cityCN + ".json";} else if (citylevel == "city") {uploadedDataURL ="https://geo.datav.aliyun.com/areas_v3/bound/" + cityCN + "_full.json";} else {uploadedDataURL ="https://geo.datav.aliyun.com/areas_v3/bound/" + cityCN + "_full.json";}return uploadedDataURL;
}

使用

<!-- :defaultMap="defaultMap" -->
<mapChart :list="scatterList" @changeMapData="changeMapData" />import mapChart from "@/views/universal-visuali/components/charts/map/mapChart.vue";// 默认的地图数据
let defaultMap = {// prefix: "china",// adcode: "110000",// name: "全国",prefix: "province",adcode: "150000",name: "内蒙古自治区",
};
// 标点
let scatterList = ref<any>([{FarmName: "养殖场一场",Admin: "小王",Livestock: 10000,Address: "江苏省连云港市",Long: 109.494324,Lati: 19.598813,},{FarmName: "向东养殖户",Admin: "向东",Livestock: 0,Address: "长虹科技大厦",Long: 113.964139785699,Lati: 22.544018837551,},{FarmName: "牧养殖种植合作社",Admin: "马胜军",Livestock: 91,Address: "广东省云浮市新兴县",Long: 112.231496832189,Lati: 22.701890082606,},{FarmName: "苏垦牧场",Admin: "小刘",Livestock: 8080,Address: "江苏省连云港连云区农场",Long: 119.43188,Lati: 34.62367,},
]);
const changeMapData = (info: any) => {console.log(info);
};
