我的任务
分享在jsp页面中中包含输入条件查询,输入条件后查询第一页正常,但是翻页后条件就无效了
<%
FlowCardService flowCardService = (FlowCardService)this.getServletContext().getAttribute(FlowCardService.class.getName());
int pageNo = 1;
int pageSize = 2;
String clientId = request.getParameter("clientId");
if (clientId == null) {
clientId = "";
}
String clientName = request.getParameter("clientName");
if (clientName == null) {
clientName = "";
}
String beginDate = request.getParameter("beginDate");
if (beginDate == null) {
beginDate = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
}
String endDate = request.getParameter("endDate");
if (endDate == null) {
endDate = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
}
PageModel pageModel = flowCardService.findAllFlowCard(pageNo, pageSize, clientId, beginDate, endDate);
String queryCon = "&clientId=" + clientId + "&clientName=" + clientName + "&beginDate=" + beginDate + "&endDate=" + endDate;
System.out.println(queryCon);
%>
//JavaScript中的相关代码
function topPage() {
window.self.location = "flow_card_maint.jsp?pageNo=1<%=queryCon%>";
}
function previousPage() {
window.self.location = "flow_card_maint.jsp?pageNo=<%=pageModel.getPreviousPageNo()%><%=queryCon%>";
}
function nextPage() {
window.self.location = "flow_card_maint.jsp?pageNo=<%=pageModel.getNextPageNo()%><%=queryCon%>";
}
function bottomPage() {
window.self.location = "flow_card_maint.jsp?pageNo=<%=pageModel.getBottomPageNo()%><%=queryCon%>";
}
function queryFlowCard() {
with(document.forms[0]) {
action="flow_card_maint.jsp";
method="post";
submit();
}
}
说明：PageModel在其他页面都运行正常，加上了“<%=queryCon%>”后翻页功能失效！
queryCon打印出来的 “&clientId=2001&clientName=北京市中医药股份有限公司&beginDate=2016-08-01&endDate=2016-08-19”，也正常

问题找到了，是一个小错误。忘了把 pageNo 的值重新传回来，应该在jsp中加入
，不过还是感谢大家的帮忙！
String pageNoStr = request.getParameter("pageNo");
if (pageNoStr != null && !"".equals(pageNoStr)) {
pageNo = Integer.parseInt(pageNoStr);
}

不用加queryCon吧，
String queryCon = "&clientId=" + clientId + "&clientName=" + clientName + "&beginDate=" + beginDate + "&endDate=" + endDate;[/quote]
那就是翻页的时候条件参数缺失，比如你的queryCon在翻页的时候没有同时维护条件查询的参数，你输入条件查询，那个条件参数也是时刻都要带上的

是我没写清楚，PageModel就是分页的
代码如下
public class PageModel {
private List list;
private int totalRecords;
private int pageSize;
private int pageNo;
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
public int getTotalRecords() {
return totalRecords;
}
public void setTotalRecords(int totalRecords) {
this.totalRecords = totalRecords;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getPageNo() {
return pageNo;
}
public void setPageNo(int pageNo) {
this.pageNo = pageNo;
}
/**
* 总页数
* @return
*/
public int getTotalPages() {
return (this.totalRecords + this.pageSize -1)/this.pageSize;
}
/**
* 上一页
* @return
*/
public int getPreviousPageNo() {
if(this.pageNo <= 1) {
return 1;
}
return this.pageNo - 1;
}
/**
* 下一页
* @return
*/
public int getNextPageNo() {
if (this.pageNo >= this.getBottomPageNo()) {
return this.getBottomPageNo();
}
return this.pageNo + 1;
}
/**
* 尾页
* @return
*/
public int getBottomPageNo() {
return this.getTotalPages();
}
}

我在网页上 查看源文件 了，
function topPage() {
window.self.location = "flow_card_maint.jsp?pageNo=1&clientId=&clientName=&beginDate=2016-08-01&endDate=2016-08-19";
}
function previousPage() {
window.self.location = "flow_card_maint.jsp?pageNo=1&clientId=&clientName=&beginDate=2016-08-01&endDate=2016-08-19";
}
function nextPage() {
window.self.location = "flow_card_maint.jsp?pageNo=2&clientId=&clientName=&beginDate=2016-08-01&endDate=2016-08-19";
}
function bottomPage() {
window.self.location = "flow_card_maint.jsp?pageNo=3&clientId=&clientName=&beginDate=2016-08-01&endDate=2016-08-19";
}
点击下一页后，页面不改变，链接也没变

"flow_card_maint.jsp?pageNo=<%=pageModel.getBottomPageNo()%><%=queryCon%>"
pageNo是第一个参数，后面这个<%=queryCon%>应该是作为第二个参数吧，比如：
pageNo=<%=pageModel.getBottomPageNo()%>&queryCon=<%=queryCon%>"

执行window.self.location之前把你的连接打印出来看一下

不好意思，刚才没看见你的分页

是框架带的分页吗？如果是那就去后台看看参数到底传过去了没，如果不是把分页的代码贴出来看看。
