最近研究了下大文件上传的方法，找到了webuploader js 插件进行大文件上传，大家也可以参考这篇文章进行学习：《Web Uploader文件上传插件使用详解》

使用webuploader分成简单直选要引入
HTML部分
选择文件
初始化Web Uploader
jQuery(function() { $list = $(#thelist),$btn = $(#ctlBtn),state = pending,uploader; uploader = WebUploader.create({// 不压缩imageresize: false,// swf文件路径swf: uploader.swf,// 文件接收服务端。server: upload.php,// 选择文件的按钮。可选。// 内部根据当前运行是创建，可能是input元素，也可能是flash.pick: #picker,chunked: true,chunkSize:2*1024*1024,auto: true,accept: { title: Images, extensions: gif,jpg,jpeg,bmp,png, mimeTypes: image/*} });
upload.php处理
以下是根据别人的例子自己拿来改的php 后台代码
