file-upload

使用原生 js 实现的文件上传目前没有加文件类型和大小判断,后期会不定时更新 适用于 vue&react 等前端框架 Files uploaded using native js are not judged by file type and size at present, and will be updated irregularly later

Applicable to front-end frameworks such as vue&read

使用方法 usage method

vue 中

import {upload} from 'db-file'

upload 需要传入一个方法来接收上传的 file 对象 Upload needs to pass in a method to receive the uploaded file object

提供 api

upload(callback,type,size)

callback 回调函数 Callback function

type 文件类型 例:['txt','png'] Example of file type: ['txt ',' png ']

size 文件大小 例: 1024或1024*100 传数字 Example of file size: 1024 or 1024 * 100 for digital transmission

downLoad(fileName,data) 下载文件流 Download file stream

fileName 文件名称 Document name

data 文件流

uploadBase(e[0]) 文件转base64 返回一个Promise

调用

调用
upload(back)

function back(e,success,type) {

console.log(e.target.files)//文件流对象&&Filestream Object 1.0.7版本以前
console.log(e)// 1.0.8版本以后
e>>> File stream



type 校验不通过类型 size||type

success 布尔值 false

}

html 中

引入 file.js 文件 调用方法同上
