篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了批量导入数据（excel模板文件方式）相关的知识，希望对你有一定的参考价值。
批量导入数据： 1.在webapp下的template文件下导入excel模板文件 1.前端：提供下载模板文件 <!DOCTYPE html> <html> <head> <!-- 页面meta --> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title>传智健康</title> <meta name="description" content="传智健康"> <meta name="keywords" content="传智健康"> <meta content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no" name="viewport"> <!-- 引入样式 --> <link rel="stylesheet" href="../plugins/elementui/index.css"> <link rel="stylesheet" href="../plugins/font-awesome/css/font-awesome.min.css"> <link rel="stylesheet" href="../css/style.css"> <link rel="stylesheet" href="../css/orderset.css"> <!-- 引入组件库 --> <script src="../js/vue.js"></script> <script src="../plugins/elementui/index.js"></script> <script type="text/javascript" src="../js/jquery.min.js"></script> <script src="../js/axios-0.18.0.js"></script> </head> <body class="hold-transition"> <div id="app"> <div class="content-header"> <h1>预约管理<small>预约设置</small></h1> <el-breadcrumb separator-class="el-icon-arrow-right" class="breadcrumb"> <el-breadcrumb-item :to="{ path: ‘/‘ }">首页</el-breadcrumb-item> <el-breadcrumb-item>预约管理</el-breadcrumb-item> <el-breadcrumb-item>预约设置</el-breadcrumb-item> </el-breadcrumb> </div> <div class="app-container"> <div class="box"> <div class="box ordersetting"> <el-card class="box-card"> <div class="boxMain"> <el-button style="margin-bottom: 20px;margin-right: 20px" type="primary" @click="downloadTemplate()">模板下载</el-button> <el-upload action="/ordersetting/upload.do" name="excelFile" :show-file-list="false" :on-success="handleSuccess" :before-upload="beforeUpload"> <el-button type="primary">上传文件</el-button> </el-upload> </div> <div> 操作说明：请点击"模板下载"按钮获取模板文件，在模板文件中录入预约设置数据后点击"上传文件"按钮上传模板文件。 </div> </el-card> <div class="calendar"> <!-- 年份 月份 --> <div class="month"> <div class="currentdate"> <span class="choose-year">{{ currentYear }}年</span> <span class="choose-month">{{ currentMonth }}月</span> </div> <div class="choose"> <span @click="goCurrentMonth(currentYear,currentMonth)" class="gotoday">今天</span> <span @click="pickPre(currentYear,currentMonth)">?</span> <span @click="pickNext(currentYear,currentMonth)">?</span> </div> <div class="clearfix"></div> </div> <!-- 星期 --> <div class="caldate"> <ul class="weekdays"> <li>周一</li> <li>周二</li> <li>周三</li> <li>周四</li> <li>周五</li> <li>周六</li> <li>周日</li> </ul> <!-- 日期 --> <ul class="days"> <!-- v-for循环 每一次循环用<li>标签创建一天 --> <li v-for="dayobject in days"> <template> <!-- 非当前月份 --> <div class="other-month" v-if="dayobject.day.getMonth()+1 != currentMonth"> {{ dayobject.day.getDate() }} </div> <!-- 当前月 --> <div class="everyday" v-if="dayobject.day.getMonth()+1 == currentMonth"> <span class="datenumber">{{ dayobject.day.getDate()}}</span> <template> <template v-for="obj in leftobj"> <template v-if="obj.date == dayobject.day.getDate()"> <template v-if="obj.number > obj.reservations"> <div class="usual"> <p>可预约{{obj.number}}人</p> <p>已预约{{obj.reservations}}人</p> </div> </template> <template v-else> <div class="fulled"> <p>可预约{{obj.number}}人</p> <p>已预约{{obj.reservations}}人</p> <p>已满</p> </div> </template> </template> </template> <button v-if="dayobject.day > today" @click="handleOrderSet(dayobject.day)" class="orderbtn">设置</button> </template> </div> </template> </li> </ul> </div> </div> </div> </div> </div> </div> </body> <!-- 引入组件库 --> <script src="../js/vue.js"></script> <script src="../plugins/elementui/index.js"></script> <script type="text/javascript" src="../js/jquery.min.js"></script> <script> new Vue({ el: ‘#app‘, data:{ today:new Date(),//当前日期 currentDay: 1, currentMonth: 1, LocalMonth: 1, currentYear: 1970, currentWeek: 1, days: [], leftobj: []//用于装载页面显示的月份已经进行预约设置的数据 }, created: function () {//在vue初始化时调用 // 1：初始化当前时间对应的日期，在页面上展示日历 this.initData(null);
