elemetUi 组件--el-upload实现上传Excel文件的实例
【需求】实现上传Excel文件,在上传到服务器时,还要附加一个参数,在请求上传文件接口前,先要进行文件格式判断。
【知识点】
1、el-upload 官方文档中,主要用到了以下属性:
data
可选参数, 上传时附带的额外参数
name
可选参数, 上传的文件字段名
before-upload
可选参数, 上传文件之前的钩子,参数为上传的文件,若返回 false 或者返回 Promise 且被 reject,则停止上传。
2、split进行字符串截取
【分析】
<template> <div> <div><strong><span></span><span>上传数据</span></strong></div> <div> <el-form :model="ruleForm" ref="ruleForm" label-width="100px"> <el-form-item label="部门" prop="name"> <el-select v-model="form.type" placeholder="请选择"> <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value"> </el-option> </el-select> </el-form-item> <el-form-item> <el-upload ref="upload" action="http://10.1.20.218:8088/gnh-webadmin-platfrom/api/v1/sendSalaryBillGeinihua" :on-preview="handlePreview" :before-upload="beforeAvatarUpload" :on-remove="handleRemove" :file-list="fileList" :auto-upload = 'false' :on-success = 'handleSuccess' :data="form"> <el-button slot="trigger" size="small" type="primary">选取文件</el-button> <el-button size="small" type="success" @click="submitUpload">上传到服务器</el-button> <div slot="tip">只能上传xls/xlsx文件</div> </el-upload> </el-form-item> </el-form> </div> </div> </template> <script> export default { data() { return { options: [{ value: '1', label: '帅哥部' }, { value: '2', label: '美女部' }], fileName:'', fileList:[], ruleForm: { // name: '', isShow: '0' }, form:{ type:'1' }, }; }, methods: { submitUpload() { this.$refs.upload.submit(); }, beforeAvatarUpload(file) { let Xls = file.name.split('.'); if(Xls[1] === 'xls'||Xls[1] === 'xlsx'){ return file }else { this.$message.error('上传文件只能是 xls/xlsx 格式!') return false } }, handleRemove(file, fileList) { }, handlePreview(file) { }, handleSuccess(res,file,fileList){ if(res.code===20000){ this.$message({ message: '上传成功!', type: 'success' }); }else { this.$message({ message: res.msg, type: 'error' }); } } } } </script> <style scope> input[type="file"] { display: none; } .el-upload-list{ width: 200px; } .el-select { width: 135px; } </style>
