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:

        <map class="navi_map"  include-points='{
       {points}}' longitude="{

       {latitude}}" polyline="{
       {polyline}}" markers="{
       {markers}}" bindcallouttap="bindcallouttap" bindmarkertap="markertap" style="width: 100%; height: {
       {view.Height}}px;" wx:if="{
       {hasMarkers}}" scale="10" ></map>
      </view>
      <view class="maptext" wx:if="{
       {mapList!=''}}">
        <view  class="news">
            <view wx:if="{
