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）
<template>
<div class="main" :style="'height: ' + mainHeight + 'px;'">
<div class="side_bar">
清除地图上的覆盖物 <em class="ball ball-red" @click="clearOverlays()">1</em>
添加弧线 <em class="ball ball-red" @click="addCurve()">2</em>
添加自定义覆盖物 <em class="ball ball-red" @click="addNodeNumber()">3</em>
添加图片 <em class="ball ball-red" @click="addImgMarker()">4</em>
