代码很整合很简单,主要记录操作思路,注意回调百度地图api的回调函数
@/utils/map.js
let Map = { BaiDuMap(ak) { return new Promise(function (resolve, reject) { window.init = function () { resolve(BMap) } const script = document.createElement("script"); script.type = "text/javascript"; script.src = "http://api.map.baidu.com/api?v=2.0&ak=" + ak + "&callback=init"; script.onerror = reject; document.head.appendChild(script); const script2 = document.createElement("script"); script2.type = "text/javascript"; script2.src = "http://api.map.baidu.com/library/CurveLine/1.5/src/CurveLine.min.js"; script2.onerror = reject; document.head.appendChild(script2); }) } } export { Map }
代码中使用(主要是覆盖物(自定义)的创建与清除)

最终可以做出点有意思的东西玩玩:
