Loadmore

Used to display loading status at the bottom of lists.

Basic Usage

Introduce this component at the bottom of the list that needs to be loaded. When scrolling to the bottom of the list, display different text by setting state.

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

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

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

:deep(.loadmore) {
  background-color: #f4f4f4;
  margin: 20px 0;
}

Custom Text

Display different text for different states by setting loading-text, finished-text, error-text along with state

<wd-loadmore custom-class="loadmore" state="loading" loading-text="Custom Loading Text" />

<wd-loadmore custom-class="loadmore" state="finished" finished-text="Custom Finished Text" />

<wd-loadmore custom-class="loadmore" state="error" error-text="Custom Error Text" />

Click to Continue Loading

When state is error, clicking on the text will trigger the loadmore event

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

Application Implementation

Implement loading more when scrolling to the bottom with the onReachBottom event

<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">This is a test {{ index + 1 }}</view>
  </view>
  <wd-loadmore :state="state" @reload="loadmore" />
</view>

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)
}

.list-item {
  position: relative;
  display: flex;
  padding: 10px 15px;
  background: #fff;
  color: #464646;
}

.list-item:after {
