ElementUI 分页

    一、概述

    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

    二、完整代码

    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>

          <div class="cantainer">
            <el-table style="width: 100%;"
                      :data="userList.slice((currentPage-1)*pagesize,currentPage*pagesize)"

    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>
