👉 前言

在 Vue + elementUi 开发中，当某些新增表单数据过多时，为了提高新增数据的效率，往往会需要实现批量新增的功能。为此，我们就需要封装一个批量新增弹窗的功能组件，因实际场景需要，本次封装的批量导入组件，涵盖附件上传功能，组件仅以抛砖引玉！ 需要按照实际应用场景进行调整！

👉 一、封装组件对应API及绑定事件

> Attributes

参数	说明	类型	可选值	默认值
url	批量导入模板文件上传地址	String	-	必填
title	批量导入标题	String	-	批量导入
uploadTableFileUrl	模板导入列表数据中附件上传地址	String	-	必填
restrictFileTypes	模板文件可上传附件类型限制	Array	‘xlsx’, ‘xls’…文件类型	[ ]
fileName	模板文件流入参名称	String	-	files
fileData	模板上传参数Data	Object	-	null
downFileName	模板下载按钮文本	String	-	下载
columnArray	附件列表表头配置（需与后端沟通）	Array	-	[ ]
tableTypeOpinion	列表类型切换配置参数	Array	-	[{label: ‘类型一’,value: ‘类型一’}…]
tableApi	获取列表数据的Axios方法名称，需要按照应用场景封装的Axios请求方式修改组件内部代码	String	-	必填
fileDeleteApi	模板数据列表中的Axios方法名称，需要按照应用场景封装的Axios请求方式修改组件内部代码	String	-	必填
uploadFileIdName	列表附件上传入参时对应的ID名称	String	-	id
rowFileIdName	列表数据的ID名称，与uploadFileIdName 配合使用，uploadFileIdName 入的参数为rowFileIdName对应的值	String	-	id
outSideDownFn	父组件中对应的下载模板的方法名	String	-	必填
outSideShowName	外部引用子组件的显隐判断参数名	String	-	showFileUp
showTableType	控制是否显示列表类型切换功能	Boolean	-	false
tableTypeName	列表类型切换时，请求列表入参名	String	-	tableType
importDataTips	导入提示	String	-

> Event

方法名	说明	参数
tableTypeChange	列表类型切换组件发生变更时触发	change值
upLoadSuccess	导入模板文件成功时触发	文件上传接口返回res
getRow	列表操作方法对应点击触发方法	操作事件类型，与columnArray 配置中定义的配置相关
submit	点击保存时触发	请求参数

👉 二、实现案例
