uniapp实现腾讯地图定位，生成点，多点连线，清空点线，卫星地图等功能

功能：

        1.地图上标点，点有内容，点击点后可以查看点的信息，详情

        2.点击地图生成点，点击多个点后可以实现点连线功能

        3.点击按钮后，可以把生成的点清空

        4.卫星地图和默认地图切换功能

1.完整代码+字段讲解

1.latitude：纬度

2.enable-satellite：卫星地图切换

3.longitude：经度

4.scale：缩放值

5.markers：标点，可以设置点内容，callout：点的文本框内容设置

6.polygons：连线用的

7.@callouttap：点击点上面的文本框可以弹出遮罩层和内容

<template>
	<view class="content">
		<map :enable-satellite="isMap" style="width: 100%; height: 100vh;" :latitude="latitude" :longitude="longitude"
			:scale="scale" :markers="markers" :polygons="polygons" @tap="mapTap" @callouttap="onCallouttap">
			<view class="btnmap" @click="isMap=!isMap">{
   
   {isMap?'腾讯地图':'卫星地图'}}</view>
			<!-- 覆盖在原生组件的文本视图 -->
			<!-- 遮罩层 -->
			<view v-if="popupShow" @click="popupShow=false" class="popup">
			</view>
			<view v-if="popupShow" class="deltail">
