先認識一下他的屬性。

?

var settings = $.extend({// Required Settings，這3個必須的咯。id : $this.attr('id'), // The ID of the DOM object，IDswf : 'uploadify.swf', // SWF file 路徑 uploader : 'uploadify.php', // 服務器處理路徑// Options，下面是可設置的屬性auto : true, // Automatically upload files when// added to the queue，是否添加以后就自動上傳。buttonClass : '', // A class name to add to the// browse button DOM objectbuttonCursor : 'hand', // The cursor to use with// the browse buttonbuttonImage : null, // (String or null) The path to// an image to use for the Flash// browse button if not using// CSS to style the buttonbuttonText : 'SELECT FILES', // The text to use// for the browse// button 文件上傳的名字checkExisting : false, // The path to a server-side// script that checks for// existing files on the// server，判斷是否已存在相應文件debug : false, // Turn on swfUpload debugging modefileObjName : 'Filedata', // The name of the file// object to use in your// server-side script，對應request的name是什么 **fileSizeLimit : 0, // The maximum size of an// uploadable file in KB// (Accepts units B KB MB GB if// string, 0 for no limit) 文件大小限制，0表示不限制。fileTypeDesc : 'All Files', // The description for// file types in the// browse dialog 文件描述fileTypeExts : '*.*', // Allowed extensions in the// browse dialog// (server-side validation// should also be used)，允許的擴展類型height : 30, // The height of the browse button，按鈕高度itemTemplate : false, // The template for the file// item in the queuemethod : 'post', // The method to use when// sending files to the// server-side upload script，提交方法，默認為postmulti : true, // Allow multiple file selection in// the browse dialog，是否允許多文件選擇，默認為trueformData : {}, // An object with additional data to// send to the server-side upload// script with every file uploadpreventCaching : true, // Adds a random value to// the Flash URL to prevent// caching of it (conflicts// with existing parameters)progressData : 'percentage', // ('percentage' or// 'speed') Data to// show in the queue// item during a// file uploadqueueID : false, // The ID of the DOM object to// use as a file queue (without// the #)，文件隊列。queueSizeLimit : 999, // The maximum number of// files that can be in the// queue at one timeremoveCompleted : true, // Remove queue items from// the queue when they are// done uploading，完成以后自動移除。removeTimeout : 3, // The delay in seconds before// removing a queue item if// removeCompleted is set to// true，移出的時間requeueErrors : false, // Keep errored files in the// queue and keep trying to// upload them，保持錯誤的文件在隊列里面，并可以重新上傳successTimeout : 30, // The number of seconds to// wait for Flash to detect// the server's response// after the file has// finished uploading，完成以后等待服務器30秒uploadLimit : 0, // The maximum number of files// you can upload，上傳限制。width : 120, // The width of the browse button，按鈕寬度// Events，重載的事件，不重載的話，則會執行自己的再執行原生的 overrideEvents : []}, options);

2.接著是他的事件

onCancel :function(file){}//取消方法 onClearQueue onDestroy onDialogClose onDialogOpen onDisable onEnable onFallback onInit onQueueComplete onSelect onSelectError onSWFReady

／／上傳完成 onUploadComplete：　function(file) {alert('The file ' + file.name + ' finished processing.');?} onUploadError onUploadProgress onUploadStart onUploadSuccess

方法:

$('#file_upload').uploadify('cancel',"*"); // 有*的話，則隊列里的所有會// 刪掉或上傳，沒有則作用于// 第一個 $('#file_upload').uploadify('upload','*'); $('#file_upload').uploadify('stop'); $('#file_upload').uploadify('settings','buttonText','BROWSE'); $('#file_upload').uploadify('disable', true); // true - disable,false - enable $('#file_upload').uploadify('destroy');
