1.介紹幾個組件

1.1 scroll-view 組件

注意：使用豎向滾動時，需要給一個固定高度，通過 WXSS 設(shè)置 height。

1.2 image組件

注意：mode有12種模式，其中3種是縮放模式，9種是裁剪模式。

1.3 Icon組件

iconType: [
‘success’, ‘info’, ‘warn’, ‘waiting’, ‘safe_success’, ‘safe_warn’,
‘success_circle’, ‘success_no_circle’, ‘waiting_circle’, ‘circle’, ‘download’,
‘info_circle’, ‘cancel’, ‘search’, ‘clear’
]

2.列表的上拉加載和下拉刷新的實現(xiàn)

2.2.1 detail.wxml 布局文件

<loading hidden="{{hidden}}" bindchange="loadingChange">
    加載中...
  </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"> 標(biāo)題:{{item.title}}</view>
       <view style="margin:5px;color:red;font-size:6px"> 來源:{{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>玩命的加載中...</text></view>
      <view wx:else><text>沒有更多內(nèi)容了</text></view>
    </view>
 </scroll-view>
