[Use uploadify2.1] [Spring MVC uploadify2.1] batch file and Image Upload

Today, I want to upload images in batches. Google thinks that uploadify is still quite good in jquery's upload control and how to use it in close-up.

1. Download The resource package, tidy up the package in 2.1.0, and share the package for free.

Http://download.csdn.net/detail/dracotianlong/5232122

2. required resources

(1): jquery-1.3.2.min.js
(2): jquery. uploadify. v2.1.0.min. js
(3): swfobject. js
(4): uploadify.css
(5): uploadify.swf

3. Page reference

<SCRIPT type = "text/JavaScript" src = "$ {base}/thirdparty/uploadify/swfobject. js"> </SCRIPT>
<SCRIPT type = "text/JavaScript" src = "$ {base}/thirdparty/uploadify/jquery. uploadify. v2.1.0.min. js"> </SCRIPT>
<Link href = "$ {base}/thirdparty/uploadify/uploadify.css" rel = "stylesheet" type = "text/CSS"/>

4. Use

$ (Document). Ready (function () {$ ("# multiple_file_upload"). uploadify ({'upload': '$ {base}/thirdparty/uploadify/uploadify.swf? Random = '+ (new date ()). gettime (), 'canonicalize': '$ {base}/thirdparty/uploadify/cancel.png', 'script ':'.. /common/o_multiple_upload.do ', // The php file 'auto': false for processing file upload to be submitted, // whether to automatically start 'multi': True, // whether multiple files can be uploaded 'buttontext': 'brow', // The text on the button 'simuploadlimmit ': 1000, // The number of files uploaded simultaneously at a time 'sizelimmit ': 19871202, // set the size limit of a single file 'queuesizelimmit ': 1000, // The number of files in the queue must be 'filedesc':' format: JPG/GIF/JPEG/PNG/BMP. ', // if the following 'fileext' attribute is configured, this attribute is required ':'*. JPG ;*. GIF ;*. JPEG ;*. PNG ;*. BMP ', // allowed format oncomplete: function (event, queueid, fileobj, response, data) {// $ (' <li> </LI> '). appendto ('. files '). text (response); var picindexplus = picindex ++; var uploadpath = response; $ ('# picbefore '). before (pictpl (picindexplus); var uploadimgpathid = "uploadimgpath" + (picindexplus); document. getelementbyid (uploadimgpathid ). value = uploadpath;}, onerror: function (event, queueid, fileobj) {alert ("file:" + fileobj. name + "Upload Failed") ;}, oncancel: function (event, queueid, fileobj) {// alert ("canceled" + fileobj. name );}});});

5. Background code Java code
