vue中使用element-ui实现分页

import ElementUI from ‘element-ui‘;
import ‘element-ui/lib/theme-chalk/index.css‘;


Vue.use(ElementUI);

<template>
    <div class="all">
        <ul>
          <li
            class="single-box"
            v-for="(goods, index) in goodsData.slice((currentPage- 
    1)*pagesize,currentPage*pagesize)"
            :key="index"
          >
           
          </li>
        </ul>
        <div class="fenye">
        <el-pagination 
          background layout="prev, pager, next" 
          :page-size="pagesize"
          @current-change="current_change"
          :current-page.sync="currentPage"
          :pager-count="5"   
          :total="goodsData.length"
        >
        </el-pagination>
      </div>
    </div>
