高德地图海量点

1.先建个js文件

import AMapLoader from "@amap/amap-jsapi-loader";

const initMap = async (config) => {

return new Promise((resolve, reject) => {

AMapLoader.load({

key: "0650fbe85c708dc3388fe803d0e5d861",

// key: config.key,

version: "2.0", // 指定要加载的 JSAPI 的版本，缺省时默认为 1.4.15

plugins: [],

Loca: {

// 是否加载 Loca，缺省不加载

version: "2.0.0", // Loca 版本，缺省 1.3.2

}).then((AMap) => {

resolve(AMap)

}).catch(err => {

reject(err)

})

}

export default initMap

2. vue组件
