不用jquery，scrolltop不会不能赋值，使用 ref ，一句代码解决需求

注意：这里使用this.$nextTick是为了方便更多的人使用，在修改数据之后使用 $nextTick，可以在回调中获取更新后的 DOM

如果只是在一进入页面就滚到底部，在当前页面没有操作进行DOM更新，就可以省略this.$nextTick

<template>
      <div class="main" ref="main">
        <div ref="content">Lorem ipsum dolor sit amet consectetur adipisicing elit. Veritatis, nesciunt ea consequatur quisquam nostrum alias atque aliquam inventore expedita explicabo aspernatur doloremque distinctio necessitatibus culpa ducimus eaque accusamus. Quis, similique!
