微信小程式實戰之天氣預報
阿新 • • 發佈：2019-01-04
這個案例是仿UC中天氣介面做的中間也有點出入，預留了顯示當前城市名字和重新整理圖示的位置，自己可以寫下，也可以新增搜尋城市。值得注意的是100%這個設定好像已經不好使了，可以通過獲取裝置的高度通過資料繫結設定高度。地址：https://github.com/shuncaigao/Weather
介面主要分為四部分：
第一部分
這裡是預留的一塊可以自行新增補充下
<view class="newTopView">
<!--左邊添加當前城市名字，點選跳轉選擇城市 右邊新增重新整理當前天氣-->
</view>第二部分：
<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！ -->
<!--汙染指數-->
<text class="centerItemText" style="margin-left: 10rpx; margin-right: 10rpx">{{aqi}}</text>
<!--汙染指數對應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">
<!--資料返回的不是陣列 在js中拼接的陣列-->
<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 == 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優先順序比class高會覆蓋class中相同屬性 -->

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
