jquerymobile 下面 form 表單提交和普通html沒區別，最主要是 <form 要加一個 data-ajax='false' 不然上傳會失敗javascript

1 html代碼css

2 服務端代碼新建一個servlet，修改 dopost代碼java

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
Date date = new Date();//獲取當前時間
SimpleDateFormat sdfFileName = new SimpleDateFormat("yyyyMMddHHmmss");
//SimpleDateFormat sdfFolder = new SimpleDateFormat("yyMM");
String newfileName = sdfFileName.format(date);//文件名稱
String fileRealPath = "";//文件存放真實地址

String firstFileName="";

// 得到容器中上傳文件夾所在的物理路徑若是按日期存放，則能夠在files\\後面繼續加 sdFolder+"\\"
String savePath = this.getServletConfig().getServletContext().getRealPath("/") + "files\\";
/* System.out.println("路徑" + savePath+"; name:"+name); */
System.out.println("路徑" + savePath);
File file = new File(savePath);
if (!file.isDirectory()) {
file.mkdirs();
}

try {
DiskFileItemFactory fac = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(fac);
upload.setHeaderEncoding("UTF-8");
// 獲取多個上傳文件
List fileList = fileList = upload.parseRequest(request);
// 遍歷上傳文件寫入磁盤
Iterator it = fileList.iterator();
while (it.hasNext()) {
  FileItem obit = (FileItem)it.next();
//若是是普通表單參數

if(obit.isFormField()){ //普通域,獲取頁面參數
String field = obit.getFieldName();

if(field.equals("value1"))
{
  System.out.println(obit.getString("UTF-8"));

}
else if(field.equals("value2")){

  System.out.println(obit.getString("UTF-8"));

}
}
// 若是是多媒體

if(obit instanceof DiskFileItem){
DiskFileItem item = (DiskFileItem) obit;
// 若是item是文件上傳表單域
// 得到文件名及路徑
String fileName = item.getName();
if (fileName != null) {
firstFileName=item.getName().substring(item.getName().lastIndexOf("\\")+1);
String formatName = firstFileName.substring(firstFileName.lastIndexOf("."));//獲取文件後綴名
fileRealPath = savePath + newfileName + formatName;//文件存放真實地址

BufferedInputStream in = new BufferedInputStream(item.getInputStream());// 得到文件輸入流
BufferedOutputStream outStream = new BufferedOutputStream(new FileOutputStream(new File(fileRealPath)));// 得到文件輸出流
Streams.copy(in, outStream, true);// 開始把文件寫到你指定的上傳文件夾
//上傳成功，
if (new File(fileRealPath).exists()) {
//虛擬路徑賦值
// fileRealResistPath=sdfFolder.format(date)+"/"+fileRealPath.substring(fileRealPath.lastIndexOf("\\")+1);
//保存到數據庫
System.out.println("上傳成功了，您還能夠作其餘操做");

//System.out.println("虛擬路徑:"+fileRealResistPath);
response.getWriter().write(fileRealPath.substring(fileRealPath.lastIndexOf("\\")+1));
}

}
}
}
} catch (org.apache.commons.fileupload.FileUploadException ex) {
ex.printStackTrace();
System.out.println("沒有上傳文件");
return;
}
/* response.getWriter().write("1"); */
