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> </view> <view style='color:#999;margin-top:15rpx;' wx:if='{{item.car_info.title}}'> <view style='color:#999;margin-left:10rpx;font-size:28rpx' bindtap='apen_add'data-name='{{item.server_info.address}}' data-latitude_siji='{{item.server_info.coordinate_start}}'><image style='width:32rpx;height:32rpx' src='../../image/location.png'/> 导航至起始地：{{item.server_info.address}} </view> </view> <view style='color:#999;margin-top:15rpx;' wx:if='{{item.car_info.title}}'> <view style='color:#999;margin-left:10rpx;font-size:28rpx' bindtap='apen_add' data-name='{{item.server_info.address_end_text}}' data-longitude_siji='{{item.server_info.coordinate_end}}'><image style='width:32rpx;height:32rpx' src='/image/location.png'/> 导航至目的地： {{item.server_info.address_end_text}} </view> </view> <view style='color:#999;margin-top:15rpx;' wx:if='{{item.car_info.title}}'> <view style='color:#999;margin-left:10rpx;font-size:28rpx'> 分配时间：{{item.time_tired}}</view> </view> </view> </view> <view class='xxx'></view> </block> apen_add: function (e) { var that = this var latitude, longitude var name = e.currentTarget.dataset.name if (e.currentTarget.dataset.latitude_siji) { var latitude_siji = e.currentTarget.dataset.latitude_siji.split(',') latitude = Number(latitude_siji[0]) longitude = Number(latitude_siji[1]) } if (e.currentTarget.dataset.longitude_siji) { var longitude_siji = e.currentTarget.dataset.longitude_siji.split(',') latitude = Number(longitude_siji[0]) longitude = Number(longitude_siji[1]) } wx.getSetting({ success: (res) => { if (res.authSetting['scope.userLocation'] != undefined && res.authSetting['scope.userLocation'] != true) { wx.showModal({ title: '是否授权当前位置', content: '需要获取您的地理位置，请确认授权，否则地图定位功能将无法使用', success: function (res) { if (res.cancel) { console.info("1授权失败返回数据"); } else if (res.confirm) { //village_LBS(that); wx.openSetting({ success: function (data) { if (data.authSetting["scope.userLocation"] == true) { wx.showToast({ title: '授权成功', icon: 'success', duration: 5000 }) wx.openLocation({ latitude: latitude, longitude: longitude, name: name, scale: 28 }) } else { wx.showToast({ title: '授权失败', icon: 'success', duration: 5000 }) } } }) } } }) } else { wx.openLocation({ latitude: latitude, longitude: longitude, name: name, scale: 28 }) } } }) },

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; case '3': that.setData({ data_3: that.data.data_3.concat(res.data[i]), }) break; case '4': that.setData({ data_4: that.data.data_4.concat(res.data[i]), }) break; } } }) } else { var data = { openid: app._openid, program_id: app.jtappid, online_code: wx.getStorageSync('online_code') } var url = '/pg.php/CarTrailer/driver_order_list'; util.request(url, 'get', data, '正在加载', function (res) { for (var i = 0; i < res.data.length; i++) { res.data[i].time_tired = util.js_date_time(res.data[i].time_tired) } res.data.reverse() that.setData({ siji: true }) for (var i = 0; i < res.data.length; i++) { 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; case '3': that.setData({ data_3: that.data.data_3.concat(res.data[i]), }) break; case '4': that.setData({ data_4: that.data.data_4.concat(res.data[i]), }) break; } } }) } },
