本文實例為大家分享了微信小程序實現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優先級比class高會覆蓋class中相同屬性 --> <image class="detailInfoCircle" 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" > <image class="centerItemImage" src="../../image/leaf.png" /> <!-- 相同屬性抽出來! --> <!--污染指數--> <text class="centerItemText" >{{aqi}}</text> <!--污染指數對應name--> <text class="centerItemText">{{quality}}</text> </view> <view class="centerItem" > <image class="centerItemImage" src="../../image/wind.png" /> <text class="centerItemText" >{{windPower}}</text> <!--風--> <text class="centerItemText">{{windDirection}}</text> </view> </view>
第四部分:
<!-- 底部view --> <view class="bottomView"> <!--數據返回的不是數組 在js中拼接的數組--> <block wx:for-items="{{list}}"> <view class="bottomItemView"> <image class="bottomImage" src="{{item.day_weather_pic}}" /> <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" > <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優先級比class高會覆蓋class中相同屬性 --> <image class="detailInfoCircle" src="../../image/circle.png" /> </view> </view>

PS:
開發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:
