使用vue-cli 创建一个vue项目
安装vux,可以参考:vux快速入门
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>
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>
<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">
