vue基于vant实现上拉加载下拉刷新的示例代码

<template>
    <div>
        <!-- van-pull-refresh：下拉刷新 -->
        <van-pull-refresh v-model="isLoading" @refresh="onRefresh">
            <!-- 上拉加载 -->
            <van-list v-model="loading" :finished="finished" :immediate-check="false" finished-text="没有更多了"
                @load="onLoad" :offset="20">
                <div class="outerBox" v-for="(item,index) in list" :key="index">
                    <div>公司名称：{{item.gsmc}}</div>
                    <div>行业类别：{{item.hylb}}</div>
                    <div>进车限值：{{item.jcxz}}</div>
                </div>
            </van-list>
        </van-pull-refresh>
