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
最终效果

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>
