创建项目

使用vue-cli 创建一个vue项目

安装vux,可以参考:vux快速入门

配置

官方文档地址

打开后会看到一段话

该组件已经不再维护,也不建议使用,大部分情况下也不需要用到该组件。 建议使用第三方相关组件,相关 issue 将不会处理。

不知道作者为啥不维护了,明明需求挺多的

我没有用demo里的 LoadMore 组件,用的是 Scroller里自带的 use-pullup, use-pulldown 下面是我的配置

<!--
 height: 我用到x-header了,文档里说header高是48px,所以这里设置成-48
 -->
<scroller use-pullup :pullup-config="pullupDefaultConfig" @on-pullup-loading="loadMore"
              use-pulldown :pulldown-config="pulldownDefaultConfig" @on-pulldown-loading="refresh"
              lock-x ref="scrollerBottom" height="-48">
</scroller>

<script>
	import {Scroller, XHeader} from 'vux'

  const pulldownDefaultConfig = {
    content: '下拉刷新',
    height: 40,
    autoRefresh: false,
    downContent: '下拉刷新',
    upContent: '释放后刷新',
    loadingContent: '正在刷新...',
    clsPrefix: 'xs-plugin-pulldown-'
  }

  const pullupDefaultConfig = {
    content: '上拉加载更多',
    pullUpHeight: 60,
    height: 40,
    autoRefresh: false,
    downContent: '释放后加载',
    upContent: '上拉加载更多',
    loadingContent: '加载中...',
    clsPrefix: 'xs-plugin-pullup-'
  }

  export default {
    components: {
      XHeader,
      Scroller
    },
    mounted() {
      this.$nextTick(() => {
        this.$refs.scrollerBottom.reset({top: 0})
      })
    },
    data() {
      return {
        list: [],
        pullupDefaultConfig: pullupDefaultConfig,
        pulldownDefaultConfig: pulldownDefaultConfig
      }
    },
    methods: {
      refresh() {

      },
      loadMore() {

      }
    }
  }
</script>

请求接口遍历数据

接口服务用的是mock.js生成的数据,可以看一下这篇博客 使用mock.js随机数据和使用express输出json接口

安装 axios

yarn add axios
//...
  methods: {
    fetchData(cb) {
      axios.get('http://localhost:3000/').then(response => {
        this.$nextTick(() => {
          this.$refs.scrollerBottom.reset()
        })
        cb(response.data)
      })
    }
  }
//...

完善refresh,loadMore方法

//...
  methods: {
    refresh() {
      this.fetchData(data => {
        this.list = data.list
        this.$refs.scrollerBottom.enablePullup()
        this.$refs.scrollerBottom.donePulldown()
      })
    },
    loadMore() {
      this.fetchData(data => {
        if (this.list.length >= 10) {
          this.$refs.scrollerBottom.disablePullup()
        }
        this.list = this.list.concat(data.list)
        this.$refs.scrollerBottom.donePullup()
      })
    }
  }
//...

在组件加载的时候调用一下 loadMore 方法

//...
  mounted() {
    this.$nextTick(() => {
      this.$refs.scrollerBottom.reset({top: 0})
    })
    this.loadMore()
  }
//...

最后把html部分补全

<scroller>
  <div style="padding: 10px 0">
    <div class="box" v-for="(item, index) in list" :key="index">
      <p class="list"></p>
    </div>
  </div>
</scroller>

完整代码

<template>
	<div>
    <x-header :left-options="{'showBack': false}">上拉加载,下拉刷新</x-header>
    <scroller use-pullup :pullup-config="pullupDefaultConfig" @on-pullup-loading="loadMore"
              use-pulldown :pulldown-config="pulldownDefaultConfig" @on-pulldown-loading="refresh"
              lock-x ref="scrollerBottom" height="-48">
