我有一个单选按钮，一旦选择它，我想显示几个与其相关的选项。这些选项位于相关的 bean 上。我怎么做？
<h:panelGrid columns="2" cellpadding="0" cellspacing="0" >
<h:selectOneRadio value="#{managePaymentModel.reportFilter.options}" layout="pageDirection" label="Select Option" disabled="#{managePaymentModel.reportPreview}">
<f:selectItems value="#{managePaymentModel.reportOptions}" var="type" itemValue="#{type.value}" itemLabel="#{type.label}" />
</h:selectOneRadio>
</h:panelGrid>
@Override
public Map reportSelector() {
Map<Integer, String> map = new HashMap<Integer, String>();
map.put(ManagePaymentBeanLocal.LIST_PAYMENTS_SUMMARY, "List of Payments Summary");
map.put(ManagePaymentBeanLocal.LIST_PAYMENTS_DETAIL, "List of Payments Detail");
return map;
}
@Override
public Map reportOptions(ReportFilter filter) {
Map<Integer, String> option = new HashMap<Integer, String>();
// report configurations
switch (filter.getSelect()) {
case ManagePaymentBeanLocal.LIST_PAYMENTS_SUMMARY:
case ManagePaymentBeanLocal.LIST_PAYMENTS_DETAIL:
option.put(ReportFilter.OPTION1, "By Beneficiary");
option.put(ReportFilter.OPTION2, "By Reference");
break;
}
return option;
}
