1.介绍几个组件
注意:使用竖向滚动时,需要给一个固定高度,通过 WXSS 设置 height。
1.2 image组件
注意:mode有12种模式,其中3种是缩放模式,9种是裁剪模式。
1.3 Icon组件
iconType: [
‘success’, ‘info’, ‘warn’, ‘waiting’, ‘safe_success’, ‘safe_warn’,
‘success_circle’, ‘success_no_circle’, ‘waiting_circle’, ‘circle’, ‘download’,
‘info_circle’, ‘cancel’, ‘search’, ‘clear’
]
2.列表的上拉加载和下拉刷新的实现
2.2.1 detail.wxml 布局文件
<loading hidden="{{hidden}}" bindchange="loadingChange">
加载中...
</loading>
<scroll-view scroll-y="true" style="height: 100%;" bindscrolltolower="loadMore" bindscrolltoupper="refesh">
<view wx:if="{{hasRefesh}}" style="display: flex;flex-direction: row;align-items: center;align-self: center;justify-content: center;">
<icon type="waiting" size="45"/><text>刷新中...</text></view>
<view wx:else style="display:none" ><text></text></view>
<view class="lll" wx:for="{{list}}" wx:for-item="item" bindtap="bindViewTap"
data-title="{{item.title}}" >
<image style=" width: 50px;height: 50px;margin: 20rpx;" src="{{item.firstImg}}" ></image>
<view class="eee" >
<view style="margin:5px;font-size:8px"> 标题:{{item.title}}</view>
<view style="margin:5px;color:red;font-size:6px"> 来源:{{item.source}}</view>
</view>
</view>
<view class="tips1">
<view wx:if="{{hasMore}}" style="display: flex;flex-direction: row;align-items: center;align-self: center;justify-content: center;">
<icon type="waiting" size="45"/><text>玩命的加载中...</text></view>
<view wx:else><text>没有更多内容了</text></view>
</view>
</scroll-view>
