使用uni-app开发list列表，实现上拉加载下拉刷新的功能。

list列表使用官方推荐的uni-list组件：

上拉加载使用的官方推荐的组件uni-load-more，并使用了页面生命周期中的onReachBottom（页面滚动到底部的事件）

下拉刷新使用了页面生命周期中的onPullDownRefresh，使用onPullDownRefresh时需要在pages.json中使用到下拉刷新的页面中配置一下，并重新运行，才能起作用。

                {
			"path": "pages/personnel/personnelList",
			"style": {
				"navigationBarTitleText": "人员管理",
				"enablePullDownRefresh":true,
				"app-plus": {
					"pullToRefresh": {
						"style": "circle",
						"offset": "88px"
					}
				}
			}
		},

注意：

1。使用onPullDownRefresh时需要在pages.json中使用到下拉刷新的页面中配置enablePullDownRefresh，并且需要重新运行才能起作用。

2。默认的下拉刷新的loading从标题栏上方开始显示，如果从标题栏下方显示，需要在pages.json中配置"offset": "88px"

具体代码：

<template>
	<view>
		<uni-nav-bar left-icon="back" title="人员管理" backgroundColor="#074498" color="white" fixed="true"
			statusBar='true' @clickLeft="goBack" @clickRight="searchPerson">
			<view slot="right" class="flex_vcenter">
				<image src="../../static/images/workbeach/icon_search.png" style="width: 25px; height: 25px;"></image>
			</view>
		</uni-nav-bar>
		<uni-list :border="false">
			<uni-list-item v-for="(item,index) in personList" :key="index" :border="false" direction="column" class="item" clickable @click="gotoDetail(item)">
				<template v-slot:header>
