效果图:
NPM 安装 Loader:
javascript
npm i @amap/amap-jsapi-loader --save
并设置 key 和安全密钥:
javascript
import AMapLoader from '@amap/amap-jsapi-loader';//引入高德地图
window._AMapSecurityConfig = {
securityJsCode: "「你申请的安全密钥」",
};
AMapLoader.load({
key: "替换为你申请的 key", //申请好的 Web 端开发 Key,首次调用 load 时必填
version: "2.0", //指定要加载的 JS API 的版本,缺省时默认为 1.4.15
plugins: ["AMap.Scale"], //需要使用的的插件列表,如比例尺'AMap.Scale',支持添加多个如:['AMap.Scale','...','...']
AMapUI: {
//是否加载 AMapUI,缺省不加载
version: "1.1", //AMapUI 版本
plugins: ["overlay/SimpleMarker"], //需要加载的 AMapUI ui 插件
},
Loca: {
//是否加载 Loca, 缺省不加载
version: "2.0", //Loca 版本
},
})
.then((AMap) => {
var map = new AMap.Map("container"); //"container"为 <div> 容器的 id
map.addControl(new AMap.Scale()); //添加比例尺组件到地图实例上
})
.catch((e) => {
console.error(e); //加载错误提示
});
