1.定义一个vue. 样式根据个人情况修改.
<template>
<div class="index">
<input ref="excel-upload-input" class="excel-upload-input" type="file" accept=".xlsx, .xls" @change="handleClick">
<div class="drop" @drop="handleDrop" @dragover="handleDragover" @dragenter="handleDragover">
拖拽至此处上传
</div>
<div class="drop">
<el-button :loading="loading" style="margin-left:16px;" size="mini" type="primary" @click="handleUpload">
点击上传
</el-button>
</div>
</div>
</template>
<script>
import XLSX from 'xlsx'
export default {
name: 'Index',
props: {
beforeUpload: Function, // eslint-disable-line
onSuccess: Function// eslint-disable-line
},
data() {
return {
loading: false,
excelData: {
header: null,
results: null
}
}
},
methods: {
generateData({ header, results }) {
this.excelData.header = header
this.excelData.results = results
this.onSuccess && this.onSuccess(this.excelData)
},
handleDrop(e) {
e.stopPropagation()
e.preventDefault()
if (this.loading) return
const files = e.dataTransfer.files
if (files.length !== 1) {
this.$message.error('Only support uploading one file!')
return
}
const rawFile = files[0] // only use files[0]
if (!this.isExcel(rawFile)) {
this.$message.error('Only supports upload .xlsx, .xls, .csv suffix files')
return false
}
this.upload(rawFile)
e.stopPropagation()
e.preventDefault()
},
handleDragover(e) {
e.stopPropagation()
e.preventDefault()
e.dataTransfer.dropEffect = 'copy'
},
handleUpload() {
this.$refs['excel-upload-input'].click()
},
handleClick(e) {
const files = e.target.files
const rawFile = files[0] // only use files[0]
if (!rawFile) return
this.upload(rawFile)
},
upload(rawFile) {
this.$refs['excel-upload-input'].value = null // fix can't select the same excel
if (!this.beforeUpload) {
this.readerData(rawFile)
return
}
const before = this.beforeUpload(rawFile)
if (before) {
this.readerData(rawFile)
}
},
readerData(rawFile) {
this.loading = true
return new Promise((resolve, reject) => {
const reader = new FileReader()
reader.onload = e => {
const data = e.target.result
const workbook = XLSX.read(data, { type: 'array' })
const firstSheetName = workbook.SheetNames[0]
const worksheet = workbook.Sheets[firstSheetName]
const header = this.getHeaderRow(worksheet)
const results = XLSX.utils.sheet_to_json(worksheet)
this.generateData({ header, results })
this.loading = false
resolve()
}
reader.readAsArrayBuffer(rawFile)
})
},
getHeaderRow(sheet) {
const headers = []
const range = XLSX.utils.decode_range(sheet['!ref'])
let C
const 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 */
const cell = sheet[XLSX.utils.encode_cell({ c: C, r: R })]
/* find the cell in the first row */
let hdr = 'UNKNOWN ' + C // <-- replace with your desired default
if (cell && cell.t) hdr = XLSX.utils.format_cell(cell)
headers.push(hdr)
}
return headers
},
isExcel(file) {
return /\.(xlsx|xls|csv)$/.test(file.name)
}
}
}
</script>
<style scoped>
.index{
margin: 100px auto;
display: flex;
justify-content: center;
}
.excel-upload-input{
display: none;
z-index: -9999;
}
.drop{
border: 2px dashed #bbb;
width: 200px;
height: 160px;
line-height: 160px;
font-size: 24px;
border-radius: 5px;
text-align: center;
color: #bbb;
position: relative;
}
</style>
2.因为我在这里使用的是公共路由
在定义路由规则的同级中自定义一个公共页面.不占位置.
{
path: '/indexup',
component: Layout,
children: [
{
path: '',
name: 'indexup',
component: () => import('@/views/indexUp/indexUp.vue')
}
]
},3.最后使用
<template>
<div class="indexup">
<el-card #header>
<h3 style="text-align: center">{{ $route.query.name }}导入</h3>
<Index :before-upload="beforeUpload" :on-success="onSuccess" />
</el-card>
</div>
</template>
<script>
import Index from '../../api/index'
export default {
components: {
Index
},
methods: {
beforeUpload() {
return true
},
onSuccess({ header, results }) {
// 自定义规则.然后将中文转换成英文加密到新对象
// 因为直接拿到的值会是你自己文件里面的.我这里显示的是中文,
// 然后做了异步转义处理.如果不需要可以无视..
const obj = {
入职日期: 'timeOfEntry',
姓名: 'username',
工号: 'workNumber',
手机号: 'mobile',
转正日期: 'correctionTime'
}
const arr = results.map((item) => {
const newObj = {}
Object.keys(item).forEach((item2) => {
newObj[obj[item2]] = item[item2]
})
return newObj
})
// 这里查看你上传文件具体解析的结果.
console.log(header, results, arr, 333)
}
}
}
</script>
<style lang="scss" scoped>
.indexup{
padding: 20px
}
</style>
