不废话,直接上代码。
前端代码:
<template> <Form ref="formValidate" :model="formValidate" :rules="ruleValidate" :label-width="110"> <FormItem label="项目(全称):" prop="orgName"> <Input v-model="formValidate.orgName" placeholder="请输入项目名称"></Input> </FormItem> <FormItem label="申请人:" prop="applyName" > <Input v-model="formValidate.applyName" placeholder="请输入申请人"></Input> </FormItem> <FormItem label="电话:" prop="applyPhone"> <Input v-model="formValidate.applyPhone" placeholder="请输入电话"></Input> </FormItem> <FormItem label="生效日期:" style="float: left"> <Row> <FormItem prop="startDate"> <DatePicker type="date" format="yyyy-MM-dd" placeholder="请选择生效日期" v-model="formValidate.startData"></DatePicker> </FormItem> </Row> </FormItem> <FormItem label="失效日期:"> <Row> <FormItem prop="endDate"> <DatePicker type="date" format="yyyy-MM-dd" placeholder="请选择失效日期" v-model="formValidate.endData"></DatePicker> </FormItem> </Row> </FormItem> <FormItem label="备注:" prop="vmemo"> <Input v-model="formValidate.vmemo" type="textarea" :autosize="{minRows: 2,maxRows: 5}" placeholder="备注"></Input> </FormItem> <FormItem> <Button type="primary" @click="handleSubmit('formValidate')">生成申请单</Button> </FormItem> </Form> </template> <script> import axios from 'axios'; export default { data () { return { formValidate: { orgName: '', applyName: '', applyPhone: '', startDate: '', endDate: '', vmemo:'' }, ruleValidate: { orgName: [ { required: true, message: '项目名称不能为空!', trigger: 'blur' } ], applyName: [ { required: true, message: '申请人不能为空!', trigger: 'blur' } ], applyPhone: [ { required: true, message: '电话不能为空!', trigger: 'change' } ], startDate: [ { required: true, type: 'date', message: '请输入license有效期!', trigger: 'change' } ], endDate: [ { required: true, type: 'date', message: '请输入license有效期!', trigger: 'change' } ], } } }, methods: { handleSubmit (name) { this.$refs[name].validate((valid) => { if (valid) { axios({ method: 'post', url: this.$store.getters.requestNoteUrl, data: this.formValidate, responseType: 'blob' }).then(res => { this.download(res.data); }); } }); }, download (data) { if (!data) { return } let url = window.URL.createObjectURL(new Blob([data])) let link = document.createElement('a'); link.style.display = 'none'; link.href = url; link.setAttribute('download', this.formValidate.orgName+'('+ this.formValidate.applyName +')'+'-申请单.doc'); document.body.appendChild(link); link.click(); } } } </script>
后台:

补充知识:vue elementui 页面预览导入excel表格数据
html代码:
<el-card class="box-card"> <div slot="header" class="clearfix"> <span>数据预览</span> </div> <div class="text item"> <el-table :data="tableData" border highlight-current-row style="width: 100%;"> <el-table-column :label="tableTitle" > <el-table-column min-width="150" v-for='item tableHeader' :prop="item" :label="item" :key='item'> </el-table-column> </el-table-column> </el-table> </div> </el-card>
js代码:
import XLSX from 'xlsx' data() { return { tableData: '', tableHeader: '' } }, mounted: { document.getElementsByClassName('el-upload__input')[0].setAttribute('accept', '.xlsx, .xls') document.getElementsByClassName('el-upload__input')[0].onchange = (e) => { const files = e.target.filesconst itemFile = files[0] // only use files[0]if (!itemFile) return this.readerData(itemFile) } }, methods: { generateDate({ tableTitle, header, results }) { this.tableTitle = tableTitle this.tableData = results this.tableHeader = header }, handleDrop(e) { e.stopPropagation() e.preventDefault() const files = e.dataTransfer.files if (files.length !== 1) { this.$message.error('Only support uploading one file!') return } const itemFile = files[0] // only use files[0] this.readerData(itemFile) e.stopPropagation() e.preventDefault() }, handleDragover(e) { e.stopPropagation() e.preventDefault() e.dataTransfer.dropEffect = 'copy' }, readerData(itemFile) { if (itemFile.name.split('.')[1] != 'xls' && itemFile.name.split('.')[1] != 'xlsx') { this.$message({message: '上传文件格式错误,请上传xls、xlsx文件!',type: 'warning'}); } else { const reader = new FileReader() reader.onload = e => { const data = e.target.result const fixedData = this.fixdata(data) const workbook = XLSX.read(btoa(fixedData), { type: 'base64' }) const firstSheetName = workbook.SheetNames[0] // 第一张表 sheet1 const worksheet = workbook.Sheets[firstSheetName] // 读取sheet1表中的数据 delete worksheet['!merges']let A_l = worksheet['!ref'].split(':')[1] //当excel存在标题行时 worksheet['!ref'] = `A2:${A_l}` const tableTitle = firstSheetName const header = this.get_header_row(worksheet) const results = XLSX.utils.sheet_to_json(worksheet) this.generateDate({ tableTitle, header, results }) } reader.readAsArrayBuffer(itemFile) } }, fixdata(data) { let o = '' let l = 0 const w = 10240 for (; l < data.byteLength / w; ++l) o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w, l * w + w))) o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w))) return o }, get_header_row(sheet) { const headers = [] const range = XLSX.utils.decode_range(sheet['!ref']) let Cconst R = range.s.r /* start in the first row */ for (C = range.s.c; C <= range.e.c; ++C) { /* walk every column in the range */ var cell = sheet[XLSX.utils.encode_cell({ c: C, r: R })] /* find the cell in the first row */ var hdr = 'UNKNOWN ' + C // <-- replace with your desired defaultif (cell && cell.t) hdr = XLSX.utils.format_cell(cell) headers.push(hdr) } return headers }
