小编VBJ*_*VBJ的帖子

我搜索了一些关于最好的JavaScript或jQuery网格的问题,但我找不到我需要的东西,所以张贴这个...如果之前有人请求粘贴链接到它.谢谢!

我的要求:

1. 我正在寻找一个JavaScript(jquery偏好)可编辑表格,用户可以使用tab(如excel)从一个单元格连续移动到另一个单元格.我看过的大多数网格 - 用户必须点击每个单元格.
2. 用户将更新多个列和行,数据应在db中更新.
3. 这是一个建议而非要求 - 加载1000行是一种好的做法,是否能够处理它？

我的后台代码将在jsp/HTML和java/servlets中

谢谢你的帮助.

嗨,有人可以帮助为什么这在尝试在JSP页面中显示值时出错.我没有转换任何数字或字符串已转换为数字,但我得到NumberFormatException

我的Servlet获取显示用户记录的请求

if(action.equalsIgnoreCase("update")){
        System.out.println("Came into Update");
        userId=(int) Integer.parseInt(request.getParameter("userid"));
        nbId=request.getParameter("nbId").trim();
        System.out.println("User iD and NBid: "+ userId + nbId);

        User user=new User();
        user.setUser_id(userId);
        user.setUser_nbk(nbId);



        List userRecords=UserDAO.getUserRecord(user);
        request.setAttribute("userRecords", userRecords);
        List owningOrg=Owning_Org_DB.getOwningOrgRecords();
        request.setAttribute("owningOrg", owningOrg);
        request.getRequestDispatcher("WEB-INF/JSP/TableMaintenance/UserNewAdd.jsp").forward(request, response);

POJO:

 @Entity
 @Cache(usage=CacheConcurrencyStrategy.READ_WRITE)
  public class User {

@Id
private int user_id;
private String user_first_name;
private String user_middle_name;
private String user_last_name;

       //getters and setters methos
   }

DAO:

public static List getUserRecord(User obj){

    Logger lo=LoggerFactory.getLogger("UserDAO.getUserRecord");
    Session session= Annotationsessionfactory.getAnnotationSession();
    Transaction tx=session.beginTransaction();

    lo.debug("Request for A user Record");
    //List<User> recList=new ArrayList<User>();
    List recList=null; …

我的项目使用Spring data mongodb。直到我对其中包含文档数组字段的文档之一进行编辑后，我才出现以下错误。以前工作正常，但现在我不断收到以下错误。

我更新的字段是 Projects POJO 类中的 impapps。我不确定如何清除此错误尝试了不同的方法但没有成功。

这是我的 POJO 和 Spring Repository 类。

嗨,我是Spring的新手并且在过去几天尝试过它.它最初对我有用,但现在我收到了错误.有人可以帮忙吗 我使用的是Spring 3.1.和Hibernate 4.1.1错误我得到:

为什么在下面的示例中t,我设置时元组不会改变names = [],但是当我向names列表中添加新值时,更改会反映出来？

它看起来tuple最初是引用列表所以任何更改都反映在元组对象中,但清空它看起来像是一个新的副本.

>>> names = ['Mark','Hary']
>>> t = (names,'Lauri')
>>> t
(['Mark', 'Hary'], 'Lauri')
>>> names.append('Donna')
>>> names
['Mark', 'Hary', 'Donna']
>>> t
(['Mark', 'Hary', 'Donna'], 'Lauri')
>>> names = []
>>> names
[]
>>> t
(['Mark', 'Hary', 'Donna'], 'Lauri')
