当我们向后台请求大量数据的时候,并要在页面展示出来,请求的数据可能上百条数据或者更多的时候,并不想在一个页面展示,这就需要使用分页功能来去完成了。
本次所使用的是vue2.0+element-ui实现一个分页功能,element-ui这个组件特别丰富,分页中给我提供了一个Pagination 分页,使用Pagination 快速完成分页功能
最终效果

test.vue
<template>
  <div class="deit">
    <div class="crumbs">
      <el-breadcrumb separator="/">
        <el-breadcrumb-item><i class="el-icon-date"></i> 数据管理</el-breadcrumb-item>
        <el-breadcrumb-item>用户列表</el-breadcrumb-item>
      </el-breadcrumb>
      <div class="cantainer">
        <el-table style="width: 100%;"
                  :data="userList.slice((currentPage-1)*pagesize,currentPage*pagesize)"
        >
          <el-table-column label="id" prop="id" width="180">

代码解释
:data="userList.slice((currentPage-1)*pagesize,currentPage*pagesize)" //对数据请求的处理,最为重要的一句话
<el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="currentPage" :page-sizes="[5, 10, 20, 40]" //这是下拉框可以选择的,每选择一行,要展示多少内容 :page-size="pagesize" //显示当前行的条数 layout="total, sizes, prev, pager, next, jumper" :total="userList.length"> //这是显示总共有多少数据, </el-pagination>
