前端实现增删查改+分页，不调用后端。
大概就是对数组内的数据进行增删查改+分页
没调什么样式，不想写后端，当做练习
在这里插入图片描述

<template><div><!-- 查询 --><el-form :inline="true" :model="formQuery"><el-form-item label="时间" :label-width="formLabelWidth"><el-date-pickerv-model="formQuery.date"type="daterange"value-format="yyyy-MM-dd"start-placeholder="开始日期"end-placeholder="结束日期":default-time="['00:00:00', '23:59:59']"></el-date-picker></el-form-item><el-form-item label="姓名" :label-width="formLabelWidth"><el-inputv-model="formQuery.name"style="width: 240px"placeholder="Please input"clearable /></el-form-item><el-form-item label="地址" :label-width="formLabelWidth"><el-inputv-model="formQuery.address"style="width: 240px"placeholder="Please input"clearable /></el-form-item><el-form-item><el-button type="primary" @click="query()">查询</el-button></el-form-item><el-form-item><el-button type="success" @click="add()" class="addButton">添加</el-button></el-form-item></el-form><!-- 表格展示 --><el-table :data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)" style="width: 100%"><el-table-column type="index" label="id" width="50" /><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="180" /><el-table-column prop="address" label="Address" /><el-table-column label="操作"><template slot-scope="scope"><!--插槽知识点--><el-button type="primary" @click="onEdit(scope.$index)">编辑</el-button><!-- <el-button type="primary" @click="dialogFormEditVisible = true">编辑</el-button> --><!-- <el-button type="danger" @click="onDelete(scope.$index)">删除</el-button> --><!-- 删除二次确认 --><el-popover placement="top" width="160" v-model="scope.row.visible"><p>确定删除吗？</p><div style="text-align: right; margin: 0"><el-button size="mini" type="text" @click="scope.row.visible = false">取消</el-button><el-button type="primary" size="mini" @click="onDelete(scope.$index)">确定</el-button></div><el-button slot="reference" type="danger">删除</el-button></el-popover></template></el-table-column></el-table><!-- 分页 --><div class="block" style="margin-top: 15px"><el-paginationalign="center"@size-change="handleSizeChange"@current-change="handleCurrentChange":current-page="currentPage":page-sizes="[1, 3, 5, 7]":page-size="pageSize"layout="total, sizes, prev, pager, next, jumper":total="tableData.length"></el-pagination></div><!-- 修改弹出框 --><el-dialog :visible.sync="dialogFormEditVisible" title="修改" width="500"><el-form :model="formEdit"><el-form-item label="时间" :label-width="formLabelWidth"><el-date-pickerv-model="formEdit.date"type="date"format="yyyy-MM-dd"value-format="yyyy-MM-dd"placeholder="Pick a day" /></el-form-item><el-form-item label="姓名" :label-width="formLabelWidth"><el-inputv-model="formEdit.name"style="width: 240px"placeholder="Please input"clearable /></el-form-item><el-form-item label="地址" :label-width="formLabelWidth"><el-inputv-model="formEdit.address"style="width: 240px"placeholder="Please input"clearable /></el-form-item></el-form><template #footer><div class="dialog-footer"><el-button @click="dialogFormEditVisible = false">Cancel</el-button><el-button type="primary" @click="editConfirm()"> Confirm </el-button></div></template></el-dialog><!-- 添加弹出框 --><el-dialog :visible.sync="dialogFormAddVisible" title="添加" width="500"><el-form :model="formAdd"><el-form-item label="时间" :label-width="formLabelWidth"><el-date-pickerv-model="formAdd.date"type="date"format="yyyy-MM-dd"value-format="yyyy-MM-dd"placeholder="Pick a day" /></el-form-item><el-form-item label="姓名" :label-width="formLabelWidth"><el-inputv-model="formAdd.name"style="width: 240px"placeholder="Please input"clearable /></el-form-item><el-form-item label="地址" :label-width="formLabelWidth"><el-inputv-model="formAdd.address"style="width: 240px"placeholder="Please input"clearable /></el-form-item></el-form><template #footer><div class="dialog-footer"><el-button @click="dialogFormAddVisible = false">Cancel</el-button><el-button type="primary" @click="addConfirm()"> Confirm </el-button></div></template></el-dialog></div>
