『壹』 java如何获取上传后的文件名
同意楼上的分析，另外我想提个建议，代码为了便于阅读可以试着分步骤写。就先专定义filename和filepath，然后你属在后续的操作中想要图片出现在设定的某一区域中就可以直接使用filename，将要上传的文件名是 its.getIPTimeStampRand()+"."+item.getName().split("\\.")[1]
『贰』 如何通过FileUpLoad获取文件名，文件大小，文件路径
获得的文件：string fName = fileupload.FileName;（这里得到的包含文件路径的全名） 文件名：fName.Substring(fName.LastIndexOf("//") + 1);（这里得到的是真正的文件名）
『叁』 Java中fileupload上传文件的代码
private static DiskFileItemFactory factory;//获得磁盘文件条目工厂 private static ServletFileUpload upload;//文件上传处理类factory = new DiskFileItemFactory(); //获得磁盘文件条目工厂factory.setRepository(new File(config.getCache())); //创建缓存工厂factory.setSizeThreshold(1024*1024*2) ; //设置缓存区的大小upload = new ServletFileUpload(factory); //高水平的API文件上传处理 upload.setSizeMax(10 * 1024 * 1024);//设置文件上传的最大值upload.setFileSizeMax(2* 1024 * 1024);//设置文件上传的最大值List<FileItem> list = upload.parseRequest(request);for(FileItem item : list){ String fieldName = item.getFieldName(); //获取表单的属性名字 String fileName = item.getName() ; //获取文件名 if(item.isFormField()){//如果获取的 表单信息是普通的 文本 信息 }else{ File file = new File("d://test.txt"); item.write(file); }}
『肆』 使用FileUpload控件上传,如何获取原文件名
string str="fileupload1.filename)"; string[] s=str.Split('.'); string i=s[0];
『伍』 fileupload 获取选中文件的绝对路径
fileupload 获取选中文件的绝对路径，实现参考如下： protected void BtnUp_Click(object sender, EventArgs e) { if (FileUpload.HasFile) { string savePath = Server.MapPath("~/upload/");//指定上传文件在服务器上的保存路径 //检查服务器上是否存在这个物理路径，如果不存在则创建 if (!System.IO.Directory.Exists(savePath)) { System.IO.Directory.CreateDirectory(savePath); } savePath = savePath + "\\" + FileUpload.FileName; FileUpload.SaveAs(savePath); LabMsg.Text = string.Format("<a href='upload/{0}'>upload/{0}</a>", FileUpload.FileName); } else { LabMsg.Text = "没有选择文件!"; } }
『陆』 用fileupload控件上传文件并自定义文件名
是有个FileUpload.SaveAs(string path)方法吧，参数path定义为你要保存文件的路径以及文件名的完整格式，在这里，你可以将文件名定义为你在页面里输的文件名，后台获取此值，拼接一下字符串即可。试试这个方法，应该可行。
『柒』 用js 怎样获取FileUpload 中的文件名（不是路径）
首先获取完整的路径名字符串(可以看到路径名的最后就是文件名),然后用spilt以"\"为分割符时行整理,最后一个元素就是文件名.
『捌』 fileupload的fileItem.getName()取得文件名问题
有的浏览器会返回文件名，而有的浏览器会返回“路径”+“文件名”，针专对后者我们需要通过“字属符串截取”获取文件名：int index=filename.lastIndexOf("\\");if(index!=-1) { filename=filename.substring(index+1);}
『玖』 FileUpload怎么获取文件的类型
if (FileUp.PostedFile.ContentType == "image/pjpeg" || FileUp.PostedFile.ContentType == "image/gif" || FileUp.PostedFile.ContentType == "image/bmp") //设置上传文件类型 加上 FileUp.PostedFile.ContentType=="application/x-shockwave-flash" ———————- 备注其它类型的ContentType ".*"="application/octet-stream" ".001"="application/x-001" ".301"="application/x-301" ".323"="text/h323"

『拾』 怎么用js来获取 fileupload中的上传文件的文件名
在firefox上，input（type=file）默认获取到的value值就是文件名。在IE上，input（type=file）默认获取到的value值是路径。因此用js来获取fileupload中的上传文件的文件名需要多方面考虑。示例代码：<form action="" method="get" onSubmit="return false;"> <input type="text" name="test" id="test"> <input type="file" name="testFile" onChange="if(this.value)insertTitle(this.value);"><input type="submit" value="提交"> </form> <script language="javascript"> function insertTitle(path){var test1 = path.lastIndexOf("/"); //对路径进行截取var test2 = path.lastIndexOf("\\"); //对路径进行截取var test= Math.max(test1, test2)if(test<0){document.getElementById("test").value = path;}else{document.getElementById("test").value = path.substring(test + 1); //赋值文件名} } </script>
