loadmore 加载更多

基本用法

在需要进行加载的列表的底部引入该组件即可。当滑动到列表底部时,通过设置state展示不同的文案。

html
<wd-loadmore custom-class="loadmore" state="loading" />

<wd-loadmore custom-class="loadmore" state="finished" />

<wd-loadmore custom-class="loadmore" state="error" />
scss
:deep(.loadmore) {
  background-color: #f4f4f4;
  margin: 20px 0;
}

自定义文案

通过设置loading-textfinished-texterror-text配合state展示不同状态时的文案

html
<wd-loadmore custom-class="loadmore" state="loading" loading-text="自定义加载文案" />

<wd-loadmore custom-class="loadmore" state="finished" finished-text="自定义完成文案" />

<wd-loadmore custom-class="loadmore" state="error" error-text="自定义错误文案" />

点击继续加载

当 state 为 error 时,点击文案,组件会触发loadmore事件

html
<wd-loadmore custom-class="loadmore" state="error" @reload="loadmore" />

应用实现

配合onReachBottom事件实现滚动到底部加载更多

html
<view class="container">
  <view v-for="index in num" :key="index" class="list-item">
    <image src="https://img10.360buyimg.com/jmadvertisement/jfs/t1/70325/36/14954/36690/5dcd3e3bEee5006e0/aed1ccf6d5ffc764.png" />
    <view class="right">这是一条测试{{ index + 1 }}</view>
  </view>
  <wd-loadmore :state="state" @reload="loadmore" />
</view>
typescript
import { onLoad, onReachBottom } from '@dcloudio/uni-app'


const state = ref<string>('loading')
const num = ref<number>(0)
const max = ref<number>(60)

onReachBottom(() => {
  if (num.value === 45) {
    state.value = 'error'
  } else if (num.value < max.value) {
    loadmore()
  } else if (num.value === max.value) {
    state.value = 'finished'
  }
})

onLoad(() => {
  loadmore()
})

function loadmore() {
  setTimeout(() => {
    num.value = num.value + 15
    state.value = 'loading'
  }, 200)
}
scss
.list-item {
  position: relative;
  display: flex;
  padding: 10px 15px;
  background: #fff;
  color: #464646;
}

.list-item:after {
  position: absolute;
  display: block;
  content: '';
  height: 1px;
  left: 0;
  width: 100%;
  bottom: 0;
  background: #eee;
  transform: scaleY(0.5);
}
image {
  display: block;
  width: 120px;
  height: 78px;
  margin-right: 15px;
}
.right {
  -webkit-box-flex: 1;
  -ms-flex: 1;
  flex: 1;
}
