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>

数据请求

show_data: function () {
 var that = this;
 if (wx.getStorageSync('register') != '司机') {
 var data = {
 openid: app._openid,
 program_id: app.jtappid,
 only_num: app._openid,
 online_code: wx.getStorageSync('online_code')
 }
 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;
 case '2':
 that.setData({
 data_2: that.data.data_2.concat(res.data[i]),
 })
 break;
