微信小程序地图导航功能实现完整源代码附效果图（推荐）

正文：

一：需求及效果图展示

从后端api获取到起始地和目的地的经纬度坐标与地名。用户点击起始地便打开地图展示坐标的附近街景，路线，或者打开外部地图。

二：源代码

 <block wx:for="{{data_2}}" wx:key='index' wx:if="{{data_2.length}}">
 
     <view style='margin-left:10rpx;'>订单号： {{item.order_num}}</view>
     <view class='page_row'>
      <view class='centent'>
       <view style='margin-left:10rpx;' wx:if='{{item.server_info.linkman}}'>下单人： {{item.server_info.linkman}}
        <text style='color:#999;margin-left:40rpx;font-size:32rpx;' wx:if='{{item.server_info.tel}}'>联系电话： {{item.server_info.tel}}</text>

数据请求

   }
   var url = '/pg.php/cartrailer/roder_list';
   util.request(url, 'get', data, '正在加载', function (res) {
    res.data.reverse()
    for (var i = 0; i < res.data.length; i++) {
     res.data[i].time_xd = util.js_date_time(res.data[i].time_xd)
     switch (res.data[i].state) {
      case '1':
       that.setdata({
        data_1: that.data.data_1.concat(res.data[i]),
       })
       break;
