多附件上传功能

import { FileUpload } from '@/components/FileUpload'

<file-upload ref="fileUpload" :filelength="5"/>

filelength:最多上传多少附件

this.$refs.fileUpload.setFile(list) 回显附件列表 list 附件接口返回列表

this.$refs.fileUpload.handleSave({attachType:attachType, relationId:id}).then(ers=>{

console.log(ers) //保存成功返回

}).catch(err=>{

console.log(err) //保存失败返回

})

保存方法 attachType，relationId传入的类型和关联Id

回调函数可不写

this.$refs.fileUpload.handleSave(attachType, relationId)
