// 高德key申请和hbuilder的manifest.json配置教程
https://blog.csdn.net/pleasantsheep_/article/details/132469712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。

<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。

https://blog.csdn.net/Smile_ping/article/details/131991041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
html
<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>
