教程一

使用uniapp的map内置组件，适合标记比较少，可以一次性加载完的情况。在自己的VUE页面中增加map标签就可以了。

<template>
	<view>
		<view class="page-body">
			<view class="page-section page-section-gap">
				<map style="width: 100%; height: 300px;" 
                :latitude="latitude" 
                :longitude="longitude" 
                :markers="covers"
                @markertap="markertapHander"
                @callouttap="callouttapHander"
                >
				</map>
			</view>
		</view>
	</view>
</template>

<script>
export default {
	data() {
		return {
			id:0, // 使用 marker点击事件 需要填写id
			title: 'map',
			latitude: 39.909,
			longitude: 116.39742,
			covers: [{
				latitude: 39.909,
				longitude: 116.39742,
				iconPath: '../../../static/location.png',
                id:1,
                callout: {
                  content: "自己的弹出框内容1"
                }

			}, {
				latitude: 39.90,
				longitude: 116.39,
				iconPath: '../../../static/location.png',
                id:2,
                callout: {
                  content: "自己的弹出框内容2"
                }
			}]
		}
	},
	methods: {
        markertapHander(e){
            console.log("用户点击了marker");
            
            let id = e.detail.markerId;
            this.covers.forEach(function(item,index,array) {
                if(item.id == id){
                    item.callout.content="新的值";
                }
            });
            // 如果要刷新content的内容，请使用下面的方法，直接赋值是没有用的
            this.covers = this.covers.slice(0);
            // 这玩意有个BUG，第一次点击还是会显示以前的值，再点击一次才会显示新的值
            // 所以这种方法就适合一次性加载完所有的marker，直接显示就行
        },
        callouttapHander(){
            console.log("用户点击了callout");
        }
	}
}
</script>

教程二

适合marker点比较多，每次点击marker然后调用后台接口获取新的数据赋值的那种。这种技术的关键字是renderjs。

<template>
	<view class="app-container" style="padding-bottom: 0;">
		<view class="myBody">
			<uni-row>
				<uni-col :span="24">
					<view style="display: none;">
						<view :msg="userLanguage" :change:msg="renderJS.reviceLanguage"></view>
						<view :msg="markers" :change:msg="renderJS.reviceMarkers"></view>
						<view :msg="deviceInfo" :change:msg="renderJS.reviceDeviceInfo"></view>
						
					</view>
					<div id="mapDiv" ref="mapDiv"></div>
				</uni-col>
			</uni-row>
		</view>

	</view>

</template>

<script module="renderJS" lang="renderjs">
	export default {

				renderMarkers: null,
				renderDeviceInfo: null,
				infoWindow: null,
			};
		},
		mounted() {
			if (window.AMap) {
				setTimeout(() => {

			} else {
				const script = document.createElement('script');

						pngColorName = "map_gree";

					const pngColorPath = "static/assets/images/" + pngColorName + ".png";
					let marker = new AMap.Marker({

renderjs数据交互

renderjs如何与uniapp数据交互，请看下面教程

吐槽一下

hbuilder的map官方封装的真的是一坨 S H I，没见过这么烂的开发。本人也是第一次接触uniapp。最简单的封装就是用户传递一个html标签给你，你直接显示就完了。非在那里封装一堆没有用的标签，结果功能还没实现。不知道招的都是些什么牛鬼蛇神。

备注

凡是在网上看到slot="callout"，那就是小程序的写法，不要浪费时间。就像下面的写法

<map :style="mapStyle" show-location="true" :latitude="latitude" id="map" :longitude="longitude":markers="markers">
	<cover-view slot="callout">
		<block v-for="(item,index) in markers" :key="index">
			<cover-view class="customCallout" :marker-id="item.id">
				<cover-view class="content">
					{{item.id}} 内容
				</cover-view>
			</cover-view>
		</block>
	</cover-view>
</map>
