Plupload 是一个Web浏览器上的界面友好的文件上传模块，可显示上传进度、图像自动缩略和上传分块。可同时上传多个文件。

示例代码：

<!-- Load Queue widget CSS and jQuery -->  <style type="text/css">@import url(css/plupload.queue.css);</style>  <script type="text/javascript" src="http://www.google.com/jsapi"></script>  <script type="text/javascript">   google.load("jquery", "1.3");  </script>    <!-- Thirdparty intialization scripts, needed for the Google Gears and BrowserPlus runtimes -->  <script type="text/javascript" src="/plupload/js/gears_init.js"></script>  <script type="text/javascript" src="http://bp.yahooapis.com/2.4.21/browserplus-min.js"></script>    <!-- Load plupload and all it's runtimes and finally the jQuery queue widget -->  <script type="text/javascript" src="/plupload/js/plupload.full.min.js"></script>  <script type="text/javascript" src="/plupload/js/jquery.plupload.queue.min.js"></script>    <script type="text/javascript">  // Convert divs to queue widgets when the DOM is ready  $().ready(function() {   $("#uploader").pluploadQueue({    // General settings    runtimes : 'gears,flash,silverlight,browserplus,html5',    url : 'upload.php',    max_file_size : '10mb',    chunk_size : '1mb',    unique_names : true,      // Resize images on clientside if we can    resize : {width : 320, height : 240, quality : 90},      // Specify what files to browse for    filters : [     {title : "Image files", extensions : "jpg,gif,png"},     {title : "Zip files", extensions : "zip"}    ],      // Flash settings    flash_swf_url : '/plupload/js/plupload.flash.swf',      // Silverlight settings    silverlight_xap_url : '/plupload/js/plupload.silverlight.xap'   });     // Client side form validation   $('form').submit(function(e) {    var uploader = $('#uploader').pluploadQueue();      // Validate number of uploaded files    if (uploader.total.uploaded == 0) {     // Files in queue upload them first     if (uploader.files.length > 0) {      // When all files are uploaded submit form      uploader.bind('UploadProgress', function() {       if (uploader.total.uploaded == uploader.files.length)        $('form').submit();      });        uploader.start();     } else      alert('You must at least upload one file.');       e.preventDefault();    }   });  });  </script>    ...    <form ..>   <div id="uploader">    <p>You browser doesn't have Flash, Silverlight, Gears, BrowserPlus or HTML5 support.</p>   </div>  </form>
