在搜索容器中分页后如何获取选定的复选框值

Question

我是Liferay的新手。 我的问题是我在searchcontainer中使用复选框，当我使用分页并转到下一页时。我找不到上一页选中的复选框的复选框值。

这里是我的JSP代码：

<portlet:resourceURL var="approvedREMSURL" id="approveBtn">
    <portlet:param name="action" value="Approval"/>
    <portlet:param name="reimHistoryId" value="0"/>
</portlet:resourceURL>

//AJAX CALL
$('.approveBtn').on("click", function(){
            var reimbursementIds = [];
            $('.selectedChk').each(function(index) {
                if($(this).is(':checked')){
                    reimbursementIds.push($(this).data("reimids")); 
                }
            });

            var remsIds = JSON.stringify(reimbursementIds);

            $.ajax({
                url : '${approvedREMSURL}',
                data : {
                    remsIds : remsIds
                },
                success: function(data){
                    if($('input[type="checkbox"]:checked').length > 0){
                        alert("IDS " + remsIds);
                        alert(data);
                        var var1 =  JSON.parse(data);
                        if( var1.userRole === 'Business Unit'){
                            alert("Inside BU Loop");
                            $("#<portlet:namespace />buApproveId").val(var1.buApproveId);
                        }else if(var1.userRole === 'Accounts'){
                            alert("Inside accounts loop");
                            $("#<portlet:namespace />accountsApproveId").val(var1.accountsApproveId);
                        }
                        location.reload();
                    }else{
                        alert("Please, select at least one checkBox!!");
                    }
                },
                error: function (error) {
                    console.log("Failure Come ERROR ! ! :- ");
                }
            });
        });

//SEARCHCONTAINER CODE
<liferay-ui:search-container searchContainer="${reimbursementBusinessUnitSearchContainer}">
    <liferay-ui:search-container-results results="${reimbursementBusinessUnitSearchContainer.getResults()}"/>

    <liferay-ui:search-container-row
        className="com.intraHrms.rems.service.custom.model.ReimbursementDetailsWrapper"
        modelVar="ReimbursementDetailsWrapper" keyProperty="reimbursementid">
        <c:set var="reimId" value="${ReimbursementDetailsWrapper.reimbursementid}"/>
        <c:set var="remStatus" value="${ReimbursementDetailsWrapper.statusName}"/>
        <%
            String demo = (String)pageContext.getAttribute("reimId");
            String encodeId = Base64.getEncoder().encodeToString(demo.getBytes());
        %>
        <liferay-portlet:renderURL var="viewURL" plid="${plId}" portletName="com_intrahrms_reimbursementDetails_web_portlet_ReimbursementDetailsWebPortlet">
            <liferay-portlet:param name="reimbursementId" value="<%=encodeId%>" />
            <liferay-portlet:param name="reimbursementStatus" value="${ReimbursementDetailsWrapper.statusName}"/>
        </liferay-portlet:renderURL>

        <liferay-ui:search-container-column-text>
        <c:choose>
            <c:when test="${remStatus == 'Business Unit Approval'}">
                <input type="checkbox" class="selectedChk" data-reimids="<%=demo%>"/>
            </c:when>
            <c:otherwise>
                <input type="checkbox" disabled/>
            </c:otherwise>
        </c:choose>
        </liferay-ui:search-container-column-text>
         ......

这是我的服务资源代码。

if (Validator.isNotNull(resourceRequest.getResourceID())
                    && "approveBtn".equalsIgnoreCase(resourceRequest.getResourceID())) {
                String rems = req.getParameter("remsIds");

我正在获得rems的价值。 当分页再次调用时，我想再次使用此rems
