这篇文章将为大家详细讲解有关微信小程序地图实现展示线路的方法，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
效果图：
思路：
1、首先获取一系列的坐标点，然后将这些坐标从头到尾链接起来。（参考微信小程序地图组件polyline属性）
2、在获取的坐标点上标注某一个位置，实现打点。（参考微信小程序地图组件marker属性 ）
3、使用map组件

下面直接展示代码：
wxml:
<view class="page-section page-section-gap">
<!-- longitude="{{longitude}}" latitude="{{latitude}}" scale="16" height: {{view.Height}}px;show-location-->
<map class="navi_map" include-points='{{points}}' longitude="{{longitude}}" latitude="{{latitude}}" polyline="{{polyline}}" markers="{{markers}}" bindcallouttap="bindcallouttap" bindmarkertap="markertap" wx:if="{{hasMarkers}}" scale="10" ></map>
</view>
<view class="maptext" wx:if="{{mapList!=''}}">
<view class="news">
<view wx:if="{{mapList.polylineJson!=null}}">预计<text >{{now}}</text>送达</view>
<view class="tishi">由药店提供配送服务</view>
