前提条件：
谷歌地图需要翻墙，否则无法加载
谷歌地图说明
- 设置地图语言
<script async
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&language=ja&callback=initMap">
</script>第一种方法(web-view)：
web-view 是一个 web 浏览器组件，可以用来承载网页的容器，会自动铺满整个页面（nvue 使用需要手动指定宽高）,一般都会用nvue，否则默认占满页面
- 展示目录结构:
index.nvue
<template>
<view>
<view style="height: 100rpx;">222222222</view>
<view class="" v-if="isShow">
<web-view style="background-color: #fafafa;" ref="webview" :style="{ height: statusBarHeight + 'px'}"
@onPostMessage="getMessage" :src="webUrl"></web-view>
</view>
</view>
</template>
<script>
/**

* source :来源 根据上个界面传来的type值 实现不同的功能
*
* */
import Vue from 'vue';
export default {
data() {
return {
statusBarHeight: 500, //可视屏幕的高度
webUrl: '',
isShow: false,
lat:'',
lng:'' ,
source: "",
};
},
onLoad(e) {
console.log(e.type)
this.source = e.type;
// #ifdef APP-PLUS
this.getlocetion();
// #endif
},
methods: {
getlocetion() {
const self = this;
self.lat = '39.906217';
self.lng = '116.3912757';
self.webUrl = '/hybrid/html/maps/index' + self.source + '.html?lat=' + self.lat +
'&lng=' +
self.lng;
self.isShow = true
}
}
};

}- <script type="text/javascript" src="https://js.cdn.aliyun.dcloud.net.cn/dev/uni-app/uni.webview.1.5.2.js"></script>是什么
uni.webview.1.5.2.js 这个 JavaScript 文件为开发者提供了在 Uni-app 中使用 Webview 组件的丰富功能和接口，方便开发者在应用中集成和控制 web 页面
- <link href="http://fonts.googleapis.com/css?family=Roboto:300" rel="stylesheet" type="text/css"> 是什么
在网页中引入 Google Fonts 中的 Roboto 字体。Google Fonts 提供了大量免费的网页字体供开发者使用
上面代码就可以生成一个谷歌地图示例了
第二种方法(render.js)
renderjs是一个运行在视图层的js。它比WXS更加强大。它只支持app-vue和web；
在视图层操作dom，运行 for web 的 js库
googleMap.vue
app繁体语言加载地图，绘制marker，绘制轨迹
