背景
项目中要做一个公共的附件展示列表，针对某个模块某条记录展示，因此附件不会是大数据量，采用前端分页，使用Vue.JS+ElementUI布局展示,axios请求数据。
步骤
一、Html页面中引入JS、CSS
<!-- 引入JS -->
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<!-- import element-ui JavaScript -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
<!-- import axios JavaScript -->
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<!-- 引入样式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
建议直接下载js文件到本地，在引入到页面。
二、页面中添加ElementUI的表格
根据项目的需要可以自行选择：https://element.eleme.cn/#/zh-CN/component/table
1 <el-table :data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize).filter(data => !search || data.foton_fileoldname.toLowerCase().includes(search.toLowerCase()))" border stripe fit empty-text="暂无数据" 2 style="width: 100%"> 3 <el-table-column prop="foton_obsfilesid" 4 label="ID" 5 v-if="isIDShow"> 6 </el-table-column> 7 <el-table-column label="文件名称" 8 prop="foton_fileoldname"> 9 </el-table-column> 10 <el-table-column label="附件所属类型" 11 prop="foton_type"> 12 </el-table-column> 13 <el-table-column label="上传时间" 14 prop="createdon"> 15 </el-table-column> 16 <el-table-column align="right"> 17 <template slot="header" slot-scope="scope"> 18 <el-input v-model="search" 19 size="mini" 20 placeholder="输入关键字搜索" /> 21 </template> 22 <template slot-scope="scope"> 23 <el-button size="mini" icon="el-icon-search" circle 24 @click="handleEdit(scope.$index, scope.row)"></el-button> 25 <el-button size="mini" 26 @click="handleEdit(scope.$index, scope.row)">下载</el-button> 27 <el-button size="mini" 28 type="danger" 29 @click="handleDelete(scope.$index, scope.row)">删除</el-button> 30 </template> 31 </el-table-column> 32 </el-table>
三、引入分页组件
<div class="block" style="float:right">
<span class="demonstration"></span>
<el-pagination @size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="currentPage"
:page-sizes="pageSizes"
:page-size="pageSize"
background
layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
</div>
分页组件的使用,详细见ElementUI官网
四、JS数据与方法
表格的数据绑定不必多说，通过axios请求数据绑定到tableData集合，表格列prop与集合字段保持一致即可。
前端分页相关是重点，pageSize、pageSizes、currentPage、total字段：
data: { pageSize: 10, pageSizes: [5, 10, 15, 20, 30, 40, 50], // select选项设置：条/页 currentPage: 1, total: 0, } 分页组件方法： handleSizeChange(val) { this.pageSize = val; }, handleCurrentChange(val) { this.currentPage = val; },
前端分页实现核心就是，el-table组件的data对象数组，通过数组的slice方法，从已有的数组中返回选定的元素。
:data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)“
还可以在进行过滤筛选：
:data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize).filter(data => !search || data.foton_fileoldname.toLowerCase().includes(search.toLowerCase()))"
至此，使用Vue+ElementUI实现前端分页就实现了。
效果如下:
