微信小程序地图实现展示线路

本文实例为大家分享了微信小程序地图实现展示线路的具体代码，供大家参考，具体内容如下

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" 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="{{mapList.polylineJson!=null}}">预计<text style="color:#FF6565">{{now}}</text>送达</view>
  <view class="tishi">由药店提供配送服务</view>
 </view>
 <view class="phone_box">
  <view style="" class="right_box" data-phone="{{mapPhone}}" bindtap="makeCallPhone" wx:if="{{mapPhone!=null}}">
  <image src="{{imgUrl}}mapshop_phone.png"></image><view style="line-height:96rpx">联系商家</view>
  </view>
  <view class="left_box" data-deliverhone="{{deliverPhone}}" bindtap="makesCallPhone" wx:if="{{deliverPhone!=null}}">
