JAVA JSP中查询和刷新在同一个页面中，点击查询怎么保留查询条件
这是jsp
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/commons/taglibs_new.jsp"%>
<html>
<head>
<title>页面展示</title>
<script>
//页面展示
function query(){
with(document.forms[0]){
operAtt.value="query";
pages.value="";
Submit();
}
}
//新增记录
function add(){
location="${ctx}/CcGuarinfoAction.do?operAtt=add";
}
//修改记录
function edit(guarNo,guarType) {
location = "${ctx}/CcGuarinfoAction.do?operAtt=edit&ccGuarinfoDomain.guarNo="+guarNo+"&ccGuarinfoDomain.guarType="+guarType;
}
//删除一条记录
function delete1(guarNo,guarType){
if(confirm("确定要删除吗?")){
location="${ctx}/CcGuarinfoAction.do?operAtt=delete1&ccGuarinfoDomain.guarNo="+guarNo+"&ccGuarinfoDomain.guarType="+guarType;
}
}
//选中在页面需要删除的记录
function deleteMore(){
if(confirm("确定要删除吗?")){
with(document.forms[0]){
operAtt.value="deleteMore";
var check = document.getElementsByName("list_check");
var delstr="";
for(var i=0;i<check.length;i++){
if(check[i].checked){
delstr+= ":"+check[i].value;
}
}
delstr= delstr.substring(1,delstr.length);
delParam.value = delstr;
document.forms[0].Submit();
}
}
}
//查看信息
function showDetail(guarNo,guarType){
location="${ctx}/CcGuarinfoAction.do?operAtt=search&ccGuarinfoDomain.guarNo="+guarNo+"&ccGuarinfoDomain.guarType="+guarType;
}
</script>

[解决办法]
在action里把查询的条件保存到session里，然后返回到页面。
[解决办法]
从你页面上看，已经在查询条件中有value="${ccGuarinfoDomain.guarType}"，所以只要action中创建ccGuarinfoDomain对象，并把它保存到request作用域即可，同时我还有点疑问，既然楼主已经想到用EL来保存查询条件，难道没在anction中处理吗
[解决办法]
${ctx}/CcGuarinfoAction.do接收
ccGuarinfoDomain.guarNo和ccGuarinfoDomain.guarType这2个参数，接收参数后声明一个ccGuarinfoDomain对象，用set方法把guarNo和guarType这2个属性添加到ccGuarinfoDomain对象中，用request.setAttribute("ccGuarinfoDomain",ccGuarinfoDomain);传递对象
在jsp 中 ccGuarinfoDomain cc = (ccGuarinfoDomain)request.setAttribute("ccGuarinfoDomain");获得对象

value="${ccGuarinfoDomain.guarNo}"
改为value="${ccGuarinfoForm.ccGuarinfoDomain.guarNo}"
[解决办法]
第一种，LZ可以考虑用ajax异步请求，只刷新查询出来的数据，下面是我用的一种，ajax提交查询后在页面拼接数据，这种方法只刷新数据部分，不会刷新整个页面，具体ajax方法就看你框架里的怎么用的了。
$.ajax({
type: "post",
url: "/yoblhtjfx/queryGoodsAjax.action",
data: "goods="+goods+"&jsoncallback=?",
dataType: "json",
success: function(json)
{
var tableHTML="";
tableHTML+="<table id='tabb1' border='1' width='100%'>";
tableHTML+="<tr>";
tableHTML+="<td style='text-align: center' >选择</td>";
tableHTML+="<td style='text-align: center' >商品代码</td>";
tableHTML+="<td style='text-align: center' >商品名称</td>";
tableHTML+="<td style='text-align: center' >单位</td>";
tableHTML+="</tr>";
var list = json.list;
for(var i=0;i<list.length;i++)
{
tableHTML+="<tr>";
tableHTML+="<td style='text-align: center'><input type='radio' class='inputRadio collection' name='radioo' value='"+list[i][0]+'@'+list[i][1]+'@'+list[i][2]+"'/></td>";
tableHTML+="<td style='text-align: center'>"+list[i][0]+"</td>";
tableHTML+="<td style='text-align: center'>"+list[i][1]+"</td>";
tableHTML+="<td style='text-align: center'>"+list[i][2]+"</td>";
tableHTML+="</tr>";
}
tableHTML+="</table>";
$("#querygoodsdiv").html(tableHTML);
}
});
第二种，像上面的所说的，在action里面定义变量，接受查询条件的值，然后页面上用${变量名}就可以取到。
