vue引入百度地图api组件封装（根据地址定位）

<template>
  <div class="Map" :style="{
    height: this.height+'px',
    this.width+ 'px'
    }">
    <div  attribute to limit CSS to this component only -->
<style scoped>
  #allmap {
    height: 100%;
     100%;
  }
</style>

export function MP(ak) {
  return new Promise(function (resolve, reject) {
    window.init = function () {
      resolve(BMap)
    }
    var 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);
  })
}
