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
