微信小程序實現(xiàn)天氣預報功能

更新時間：2018年07月18日 17:13:52 作者：順子_RTFSC

這篇文章主要為大家詳細介紹了微信小程序實現(xiàn)天氣預報功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了微信小程序實現(xiàn)天氣預報功能的具體代碼，供大家參考，具體內容如下

這個案例是仿UC中天氣界面做的中間也有點出入，預留了顯示當前城市名字和刷新圖標的位置，自己可以寫下，也可以添加搜索城市。值得注意的是100%這個設置好像已經不好使了，可以通過獲取設備的高度通過數(shù)據綁定設置高度。地址：weather

界面主要分為四部分：

第一部分

這里是預留的一塊可以自行添加補充下

<view class="newTopView">
<!--左邊添加當前城市名字，點擊跳轉選擇城市 右邊添加刷新當前天氣-->
</view>

第二部分：

 <view class="topView">
 <view class="degreeView">
 <!--當前溫度-->
 <text class="degree">{{currentTemperature}}</text>
 <!--度數(shù)圖標-->
 <image class="circle" src="../../image/circle.png"></image>
 </view>
 <view class="detailInfo">
 <view class="degreeView">
 <!--夜間天氣情況-->
 <text class="detailInfoDegree">{{nightAirTemperature}}</text>
 <image class="detailInfoCircle" src="../../image/circle.png" />
 <text class="detailInfoLine">/</text>
 <!--白天天氣-->
 <text class="detailInfoDegree">{{dayAirTemperature}}</text>
 <!-- style優(yōu)先級比class高會覆蓋class中相同屬性 -->
 <image class="detailInfoCircle" style="margin-left: 57rpx; margin-right: 40rpx" src="../../image/circle.png" />
 <!-- 當前天氣名字 -->
 <text class="detailInfoName">{{weather}}</text>
 </view>
 </view>
 </view>

第三部分：

 <!-- 中間部分 -->
 <view class="centerView">
 <view class="centerItem" style="margin-right: 25rpx;">
 <image class="centerItemImage" src="../../image/leaf.png" />
 <!-- 相同屬性抽出來！ -->
 <!--污染指數(shù)-->
 <text class="centerItemText" style="margin-left: 10rpx; margin-right: 10rpx">{{aqi}}</text>
 <!--污染指數(shù)對應name-->
 <text class="centerItemText">{{quality}}</text>
 </view>
 <view class="centerItem" style="margin-left: 25rpx">
 <image class="centerItemImage" src="../../image/wind.png" />
 <text class="centerItemText" style="margin-left: 10rpx; margin-right: 10rpx">{{windPower}}</text>
 <!--風-->
 <text class="centerItemText">{{windDirection}}</text>
 </view>
 </view>

第四部分：

<!-- 底部view -->
 <view class="bottomView">
 <!--數(shù)據返回的不是數(shù)組 在js中拼接的數(shù)組-->
 <block wx:for-items="{{list}}">
 <view class="bottomItemView">
 <image class="bottomImage" src="{{item.day_weather_pic}}" style="margin-bottom: 15rpx;" />
 <text wx:if="{{item.weekday == 1}}" class="bottomText">星期一</text>
 <text wx:elif="{{item.weekday == 2}}" class="bottomText">星期二</text>
 <text wx:elif="{{item.weekday == 3}}" class="bottomText">星期三</text>
 <text wx:elif="{{item.weekday == 4}}" class="bottomText">星期四</text>
 <text wx:elif="{{item.weekday == 5}}" class="bottomText">星期五</text>
 <text wx:elif="{{item.weekday == 6}}" class="bottomText">星期六</text>
 <text wx:else="{{item.weekday == 7}}" class="bottomText">星期日</text>
 <view class="degreeView" style="margin-top: 20rpx;">
  <text class="detailInfoDegree">{{item.night_air_temperature}}</text>
  <image class="detailInfoCircle" src="../../image/circle.png" />
  <text class="detailInfoLine">/</text> 
  <text class="detailInfoDegree">{{item.day_air_temperature}}</text>
  <!-- style優(yōu)先級比class高會覆蓋class中相同屬性 -->
  <image class="detailInfoCircle" style="margin-left: 57rpx; margin-right: 40rpx" src="../../image/circle.png" />
 </view>
</view>

PS：

開發(fā)者工具無法顯示問題：是因為View沒有獲得高度，默認個高度或者直接修改wxml中height高度即可。

另外，本站在線工具小程序上有一款天氣查詢工具，還添加了城市選擇的功能，感興趣的朋友可以掃描如下小程序碼查看：
