项目需要用到上拉刷新下拉加载 所以自己手动实现了一个
组件：

<template>

    <div class="my-scroll" :class="[scrollState?'prohibit':'allow']" ref="myScroll" @scroll.passive="onScroll($event)" @touchstart="touchStart($event)" @touchmove="touchMove($event)" @touchend="touchEnd($event)"  >
        <div class="scroll-top" :style="{height:top+'px'}">
            <div v-if="aspect==2">
                <p v-if="state==6">
                    下拉刷新
                </p>
                <p v-if="state==1">
                    <i><img :src="Load"/></i>
                    <br/>
                    刷新中
                </p>
                <p v-if="state==2">松开刷新</p>
                <p v-if="state==3">
                    <i><img :src="Load"/></i>
                    <br/>
                    刷新完成
                </p>
            </div>
        </div>
        <!-- top -->
        <div class="scroll-list" :style="{ transform: 'translate3d(0, ' + top + 'px, 0)'}">
            <slot name='scrollList'></slot>
            <div class="scroll-bottom">
                <div v-if="state==4">加载中</div>
                <div v-if="state==5">加载完成</div>
                <div v-if="state==7">没有更多</div>
            </div>

上拉刷新实现思路：
1.通过touchstart获取用户第一次点击的坐标
2.通过touchmove 判断向上滑动还是向下
4.判断列表的滚动条是否在最顶部
5.然后判断在这个屏幕滑动的比例 进行状态显示
下拉加载实现思路：
1.通过判断滚动条位置实现下拉加载

样式：
