限制在使用P:Celleditor编辑时选择过去的日期:Calander

Question

我希望用户在使用p：celleditor

编辑时限制P：Calander中的过去日期（即在当前日期之前）

<p:column style="width:120px;" sortBy="#{v.promoDate}" headerText="Action Date">
    <p:cellEditor>
        <f:facet name="output">
            <h:outputText value="#{v.promoDateString}" />
        </f:facet>
        <f:facet name="input">
            <p:calendar readonlyInput="true" value="#{v.promoDate}" pattern="MMM dd, yyyy" />
        </f:facet>
    </p:cellEditor>
</p:column>

bean oneDit方法

public void onEdit(RowEditEvent event) {
    setEditMode(true);
    foodPromoDTO = (FoodPromotionDTO) event.getObject();
    Map<String, Object> sessMap = CommonUtil.getSessionMap();
    SessionDTO sessionDTO = (SessionDTO) sessMap.get(WebConstants.SESSION_DTO);
    String eid = sessionDTO.getUserDetailsDTO().getEid();
    Integer roleCountryId = sessionDTO.getLoggedinUserRoleCountryId();
    getDashboardService().addFoodPromotion(foodPromoDTO, eid, editMode, roleCountryId, sessionDTO.getLoggedinCountryCode());
    myFoodList = getFoodPromoList();
}

这是一个示例代码，它可以做到您需要的：

视图

<p:growl autoUpdate="true" showDetail="true" />
<h:form id="mainForm">
    <p:dataTable value="#{celleditionMBean.list}" var="item" editable="true" editMode="cell" widgetVar="dtVar">
        <p:ajax event="cellEdit" listener="#{celleditionMBean.onEdit}" process="date" />
        <p:column style="width:120px;" headerText="Action Date">
            <p:cellEditor>
                <f:facet name="output">
                    <h:outputText value="#{item.promoDate}" >
                        <f:convertDateTime dateStyle="date" pattern="MM dd, yyyy" />
                    </h:outputText>
                </f:facet>
                <f:facet name="input">
                    <p:calendar id="date" readonlyInput="true" value="#{item.promoDate}" pattern="MM dd, yyyy" mindate="#{celleditionMBean.current}" />
                </f:facet>
            </p:cellEditor>
        </p:column>
    </p:dataTable>
</h:form>
