最近研究了下大文件上傳的方法，找到了webuploader js 插件進行大文件上傳，大家也可以參考這篇文章進行學習：《Web Uploader文件上傳插件使用詳解》使用使用webuploader分成簡單直選要引入
!--引入CSS-- link rel="stylesheet" type="text/css" href="webuploader文件夾/webuploader.css" !--引入JS-- script type="text/javascript" src="webuploader文件夾/webuploader.js" /script HTML部分 div id="uploader" !--用來存放文件信息-- div id="thelist" /div div div id="picker" 選擇文件 /div button id="ctlBtn" 開始上傳 /button /div /div 初始化Web UploaderjQuery(function() { $list = $('#thelist'), $btn = $('#ctlBtn'), state = 'pending', uploader; uploader = WebUploader.create({ // 不壓縮image resize: false, // swf文件路徑 swf: 'uploader.swf', // 文件接收服務端。 server: upload.php, // 選擇文件的按鈕。可選。 // 內部根據當前運行是創建，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處理以下是根據別人的例子自己拿來改的php 后臺代碼header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") .
