⑵ uploadify 怎么改文件名,而且如果文件名是中文的话就不能上传了
jQuery.Uploadify 上传中文文件名出现乱码解决，无非是程序编码和系统编码不一致造成的，于是尝试修改uploadify.php文件，将：move_uploaded_file($tempFile,$targetFile);修改为：move_uploaded_file($tempFile,iconv(“UTF-8″,”gb2312″, $targetFile));
⑶ php上传文件后名字变了，如何让文件名不变，上传成功后能否获取文件链接
function uploadify(){$targetFolder = '/uploads/';$verifyToken = md5('unique_salt' . $_POST['timestamp']);if (!empty($_FILES) && $_POST['token'] == $verifyToken) {$tempFile = $_FILES['Filedata']['tmp_name'];$targetPath = $targetFolder;$savePath=$targetFolder.$_FILES['Filedata']['name'];$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];$fileTypes = array('aac','flac','mar','wma','mp3','ape','ogg');$fileParts = pathinfo($_FILES['Filedata']['name']);if (in_array($fileParts['extension'],$fileTypes)) {move_uploaded_file($tempFile,iconv("UTF-8","gb2312", $targetFile));echo $savePath;}else{echo 'Invalid file type.';}}}这个("UTF-8","gb2312", $targetFile)保持中文不被乱码或者中文上传不了问题。
⑷ uploadify上传，中文名文件 上传后文件名是乱码（ie下）
检查一下你的flash版本，adobe最近的有一个版本有这个问题，不过现在应该有一个新的版本出来了，更新一下试试
⑸ uploadify的div和object不在同一位置
本人也遇到这个问题，找到一比较“简单粗暴”的方法，改动object的位置样式，left 、top来让它和div对应起来，前提是你要将他们相应父级节点样式设置为relative。
⑹ jquery 多个 上传文件教程
jquery 实现多个上传文件教程：
首先创建解决方案,添加jquery的js和一些资源文件(如图片和进度条显示等):
jquery-1.3.2.min.jsjquery.uploadify.v2.1.0.jsjquery.uploadify.v2.1.0.min.jsswfobject.jsuploadify.css
1、页面的基本代码如下
这里用的是aspx页面(html也是也可的)
页面中引入的js和js函数如下：
<scriptsrc="js/jquery-1.3.2.min.js"type="text/javascript"></script><scriptsrc="js/jquery.uploadify.v2.1.0.js"type="text/javascript"></script><scriptsrc="js/jquery.uploadify.v2.1.0.min.js"type="text/javascript"></script><scriptsrc="js/swfobject.js"type="text/javascript"></script><linkhref="css/uploadify.css"rel="stylesheet"type="text/css"/></script>
js函数：
<scripttype="text/javascript">$(document).ready(function(){$("#uploadify").uploadify({'uploader':'image/uploadify.swf',//uploadify.swf文件的相对路径，该swf文件是一个带有文字BROWSE的按钮，点击后淡出打开文件对话框'script':'Handler1.ashx',//script：后台处理程序的相对路径'cancelImg':'image/cancel.png','buttenText':'请选择文件',//浏览按钮的文本，默认值：BROWSE。'sizeLimit':999999999,//文件大小显示'floder':'Uploader',//上传文件存放的目录'queueID':'fileQueue',//文件队列的ID，该ID与存放文件队列的div的ID一致'queueSizeLimit':120,//上传文件个数限制'progressData':'speed',//上传速度显示'auto':false,//是否自动上传'multi':true,//是否多文件上传//'onSelect':function(e,queueId,fileObj){//alert("唯一标识:"+queueId+""+//"文件名："+fileObj.name+""+//"文件大小："+fileObj.size+""+//"创建时间："+fileObj.creationDate+""+//"最后修改时间："+fileObj.modificationDate+""+//"文件类型："+fileObj.type);//}'onQueueComplete':function(queueData){alert("文件上传成功！");return;}});});
页面中的控件代码：
<body><formid="form1"runat="server"><divid="fileQueue"></div><div><p><inputtype="file"name="uploadify"id="uploadify"/><inputid="Button1"type="button"value="上传"onclick="javascript:$('#uploadify').uploadifyUpload()"/><inputid="Button2"type="button"value="取消"onclick="javascript:$('#uploadify').uploadifyClearQueue()"/></p></div></form></body>
函数主要参数：
$(document).ready(function(){$('#fileInput1').fileUpload({'uploader':'uploader.swf',//不多讲了'script':'/AjaxByJQuery/file.do',//处理Action'cancelImg':'cancel.png','folder':'',//服务端默认保存路径'scriptData':{'methed':'uploadFile','arg1','value1'},//向后台传递参数,methed,arg1为参数名,uploadFile,value1为对应的参数值,服务端通过request["arg1"]'buttonText':'UpLoadFile',//按钮显示文字,不支持中文,解决方案见下//'buttonImg':'图片路径',//通过设置背景图片解决中文问题,就是把背景图做成按钮的样子'multi':'true',//多文件上传开关'fileExt':'*.xls;*.csv',//文件过滤器'fileDesc':'.xls',//文件过滤器详解见文档'onComplete':function(event,queueID,file,serverData,data){//serverData为服务器端返回的字符串值alert(serverData);}});});
后台一般处理文件：
usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.IO;usingSystem.Net;usingSystem.Web;usingSystem.Web.Services;namespacefupload{///<summary>///Handler1的摘要说明///</summary>publicclassHandler1:IHttpHandler{publicvoidProcessRequest(HttpContextcontext){context.Response.ContentType="text/plain";HttpPostedFilefile=context.Request.Files["Filedata"];//对客户端文件的访问stringuploadPath=HttpContext.Current.Server.MapPath(@context.Request["folder"])+"\";//服务器端文件保存路径if(file!=null){if(!Directory.Exists(uploadPath)){Directory.CreateDirectory(uploadPath);//创建服务端文件夹}file.SaveAs(uploadPath+file.FileName);//保存文件context.Response.Write("上传成功");}else{context.Response.Write("0");}}publicboolIsReusable{get{returnfalse;}}}}
以上方式基本可以实现多文件的上传，大文件大小是在控制在10M以下/。
⑺ uploadify2.1版本,c#后台怎么获取上传文件的路径和文件名
更改upload.ashx这个文件public class _upload : IHttpHandler, IReadOnlySessionState, IRequiresSessionState这样就可以使用Session然后把上传文件的路径和文件名保存起来，在c#后台获取即可
⑻ jquery 的 uploadify如何将已经上传的文件删除
jQuery部分： 'onComplete':function (event, queueID, fileObj, response, data) //上传一次 { respnose //获取的就是下面PHP代码传递过来的参数。 }PHP部分（上传文件PHP：uploadify.php）：move_uploaded_file($tempFile,iconv("UTF-8","gb2312", $targetFile)); //上传文件.echo $targetFile; //输出上传文件名.
⑼ .net网站，文件上传控件
uploadify控件js: $("#uploadify_HB_SZGT").uploadify({ 'swf': '../JS/uploadify/uploadify.swf', 'uploader': '../JS/uploadify/upload_HB_SZGT.ashx', 'buttonText': '添加附件', 'buttonClass': 'button-class', 'buttonCursor': 'hand', 'fileSizeLimit': '2097152KB', 'fileTypeExts': '*.gif; *.jpg; *.png;*.pdf;*.txt;*.doc;*.wps;*.xls;*.jpeg', 'folder': 'dzka_ba', 'queueID': 'fileQueue', 'auto': true, 'multi': false, 'fileObjName': 'Filedata', 'method': 'GET', 'removeCompleted': false, 'onUploadStart': function (file) { //设置值 var fj_sbxh = $("#ContentPlaceHolder1_hidSBXH").val(); if (fj_sbxh == "") { alert("请您先登录"); return; } var fj_dzzlzlbh = $("#slDZZLZL").val(); //单证种类编号 var fj_dzzlzlmc = $("#slDZZLZL").find("option:selected").text(); //单证种类名称 var fj_sblx = $("#txtSBLX").val(); //申报类型 var fj_QFRQ = ($("#txtQFRQ").val() == "") ?

⑽ jquery插件 uploadify的buttonImg问题
'plugin/uploadify/selectHead.jpg'路径错误..前面加跟斜杠 '/plugin/uploadify/selectHead.jpg'我正在弄这个东西、对了哥们请问一下的这个'buttonText': '选择头像',怎么可以显示汉字呢。我打汉字显示的是乱码。我用的2.1.4。。。。是版本不同还是你采用了其他方法？求教一下
