微信小程序实现天气预报功能

顺子_RTFSC 人气:0

本文实例为大家分享了微信小程序实现天气预报功能的具体代码,供大家参考,具体内容如下

这个案例是仿UC中天气界面做的中间也有点出入,预留了显示当前城市名字和刷新图标的位置,自己可以写下,也可以添加搜索城市。值得注意的是100%这个设置好像已经不好使了,可以通过获取设备的高度通过数据绑定设置高度。地址:weather

界面主要分为四部分:

第一部分

这里是预留的一块可以自行添加补充下

<view class="newTopView">
<!--左边添加当前城市名字,点击跳转选择城市 右边添加刷新当前天气-->
</view>

第二部分:

 <view class="topView">
 <view class="degreeView">
 <!--当前温度-->
 <text class="degree">{{currentTemperature}}</text>
 <!--度数图标-->
 <image class="circle" src="../../image/circle.png"></image>
 </view>
 <view class="detailInfo">
 <view class="degreeView">
 <!--夜间天气情况-->
 <text class="detailInfoDegree">{{nightAirTemperature}}</text>
 <image class="detailInfoCircle" src="../../image/circle.png" />
 <text class="detailInfoLine">/</text>
 <!--白天天气-->
 <text class="detailInfoDegree">{{dayAirTemperature}}</text>
 <!-- style优先级比class高会覆盖class中相同属性 -->
 <image class="detailInfoCircle" style="margin-left: 57rpx; margin-right: 40rpx" src="../../image/circle.png" />
 <!-- 当前天气名字 -->
 <text class="detailInfoName">{{weather}}</text>
 </view>
 </view>
 </view>


第三部分:

 <!-- 中间部分 -->
 <view class="centerView">
 <view class="centerItem" style="margin-right: 25rpx;">
 <image class="centerItemImage" src="../../image/leaf.png" />
 <!-- 相同属性抽出来! -->
 <!--污染指数-->
 <text class="centerItemText" style="margin-left: 10rpx; margin-right: 10rpx">{{aqi}}</text>
 <!--污染指数对应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>
 <!--风-->
 <text class="centerItemText">{{windDirection}}</text>
 </view>
 </view>

第四部分:

<!-- 底部view -->
 <view class="bottomView">
 <!--数据返回的不是数组 在js中拼接的数组-->
 <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优先级比class高会覆盖class中相同属性 -->
  <image class="detailInfoCircle" style="margin-left: 57rpx; margin-right: 40rpx" src="../../image/circle.png" />
 </view>
</view>

PS:

开发者工具无法显示问题:是因为View没有获得高度,默认个高度或者直接修改wxml中height高度即可。

另外,本站在线工具小程序上有一款天气查询工具,还添加了城市选择的功能,感兴趣的朋友可以扫描如下小程序码查看:
