微信小程序实战之天气预报

为什么80%的码农都做不了架构师？>>>   

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：https://github.com/shuncaigao/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>

/*最近七天样式*/
.bottomImage { width: 70rpx; height: 70rpx; }

.bottomText { font-size: 28rpx; color: white; }

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
