我正在使用 JSP 和 Servlet（IDE：Eclipse，数据库：Oracle10）开发一个 Web 应用程序。
我jqGrid用来以表格格式显示记录。我使用 设计了一个header和Details表jqGrid，其中如果我们单击表的任何行，则Header表中的行将Details相应更改。jqGrid我已经为Header和Details表分开了。
现在，如果我单击Header表格行，那么它会在表格中显示jqGrid相关Details数据
但问题是Navigation Barof工作正常，Header但Table 不工作。如果我单击下一页按钮，那么它也会再次向我显示相同的结果。Navigation BarDetails
[注意：两者的添加、编辑和删除按钮都可以正常工作，只有Details表格的记录导航不起作用]
Header：
jQuery("#list10").jqGrid({
url:'ProtocolJGridServ?q=2&action=protocol',
datatype: "xml",
height: 250,
colNames:['Sr. No.','PROTOCOL_ID','DESCRIPTION','PURPOSE','PROTOCOL_TYPE','TARGET','START_DATE','END_DATE','TRIGGER_NAME'],

protID = ret.PROTOCOL_ID;
jQuery("#list10").jqGrid('setGridParam', {editurl:'ProtocolJGridServ?action=protocolEdit&protID='+protID});
jQuery('#list10').jqGrid('restoreRow',lastsel);
jQuery('#list10').jqGrid('editRow',ids,true);
lastsel=ids;
cm = $('#list10').jqGrid('getColProp',"PROTOCOL_ID"); cm.editable=true;
}
if(ids!=null)
{
var PROTOCOL_ID = $('#list10').getCell(ids, 'PROTOCOL_ID');
//for CRM_PROTOCOL_STAGES
jQuery("#list10_d2").jqGrid('setGridParam',{url:"ProtocolJGridServChildStages?action=protStages&q=1&protID="+PROTOCOL_ID,page:1});
jQuery("#list10_d2").jqGrid('setCaption',"CRM_PROT_STAGES: "+ids)

更新 1：--- Servlet 代码：
int page = Integer.parseInt(request.getParameter("page")); // get the requested page
int limit = Integer.parseInt(request.getParameter("rows")); // get how many rows we want to have into the grid
String sidx = request.getParameter("sidx"); // get index row - i.e. user click to sort
String sord = request.getParameter("sord"); // get the direction
int start = (limit* page) - limit;
String rows = request.getParameter("rows");
String param = request.getParameter("protID");
//get the data
String query = "select * from CRM_PROT_STAGES where PROTOCOL_ID ='"+param+"'";
//String query = "select * from( select * from CRM_PROT_STAGES where PROTOCOL_ID = '"+param +"' order by PROTOCOL_ID desc) where ROWNUM <= "+limit;
//String query = "select * from ( select a.*, ROWNUM rnum from ( select * from CRM_PROT_STAGES where PROTOCOL_ID = '"+param +"' ) a where ROWNUM <= "+ limit +")where rnum >="+start;
data = select.getData(query); //getData() return 2D array of data
columnNames = select.getColumnNames(); //getColumnNames() returns array of column names
int totalCount = data.length;
int totalPages = 0;
if (totalCount > 0)
{
if (totalCount % Integer.parseInt(rows) == 0)
{
totalPages = totalCount / Integer.parseInt(rows);
}
else
{
totalPages = (totalCount / Integer.parseInt(rows)) + 1;
}
}
else
{
totalPages = 0;
}
out.print("<?xml version='1.0' encoding='utf-8'?>\n");
out.print("<rows>");
out.print("<page>" + request.getParameter("page") + "</page>");
out.print("<total>" + totalPages + "</total>");
out.print("<records>" + totalCount + "</records>");
int srNo = 1;
limit = limit+start;
//for(int i=0;i<data.length;i++)
if(totalCount>0)
for(int i=start;i<limit;i++)
{
if(i<data.length)
{
out.print("<row id='" + i + "'>");
out.print("<cell>" + srNo + "</cell>");
for(int a=0;a<columnNames.length;a++)
{
out.print("<cell>"+ data[i][a] +"</cell>");
}
out.print("</row>");
srNo++;
}
}
out.print("</rows>");
data=null;
columnNames=null;
}
让我知道有什么问题吗？
