效果图

1.在util下建一个map.js

export function mymap(ak) {
  return new Promise(function(resolve, reject) {
    window.init = function() {
      resolve(mymap)
    }
    var script = document.createElement('script')
    script.type = 'text/javascript'    
    script.src = `http://api.map.baidu.com/api?v=1.0&type=webgl&ak=${ak}&mcode=35:81:1C:D3:2A:63:FB:6B:6E:1C:D4:F7:81:DF:A5:1B:89:57:83:91;uni.UNI342DC80&callback=init`	
    script.onerror = reject
    document.head.appendChild(script)
  })
}

2.在要显示地图的页面map.vue  引入    import { mymap } from "@/util/map.js";

<template>
	<view class="global">
		<view class="header">															
			<view id="allmap" class="map"></view>
		</view>		
	</view>
</template>

<script>	
	export default {		
		data() {
			return {
							
			}
		},		
		mounted() {
						
		},
		methods: {			
			
		}
	}
</script>

<script module="map" lang="renderjs">
	import { mymap } from "@/util/map.js";	
	var bmap = null;
	export default {
		data() {
			return {
				ak: '百度密钥'
			}
		},
		mounted() {				
				// ================百度地图==================
				mymap(this.ak).then((mymap) => {
					// 创建百度地图实例				
					bmap = new BMapGL.Map("allmap");
					console.log(bmap, 'this.map ')
					var point = new BMapGL.Point(120.52679016380534, 31.304840401001357);
					bmap.centerAndZoom(point, 10); //设置缩放级别	
					bmap.setTilt(43);//设置倾斜角度
					bmap.setHeading(24.5);   //设置地图旋转角度		
					bmap.enableScrollWheelZoom();
					bmap.setMapStyleV2({
						styleId: '自定义样式的id' //百度开放平台搜搜个性化地图
					});											
				});
		},
		methods: {			
			updateEcharts(newValue, oldValue, ownerInstance, instance) {
				// 监听 service 层数据变更
				
				// app端监听数据变化调用方法								
			},			
			onClick(event, ownerInstance) {
				// 调用 service 层的方法					
			},			
		}
	}
</script>
<style>	
<style lang="scss" scoped>
	.map {
		width: 100%;
		height: 500px;
	}
	
</style>
