使用JSF的单选复选框 [英] Single Select Checkbox Using JSF

问题描述

我正在JSF中创建注册表单，并且我需要使用复选框的字段为活动"，非活动"，并且这些复选框应为单选". (注意:我可以使用单选按钮来解决问题，但是由于某些问题，我必须使用复选框.)

I am creating registration form in JSF and I have field as Active, Inactive where I need to use check boxes and these checkboxes should be SINGLE SELECT ONLY. (Note: I can use radio button and solve the problem, however due to some problem I have to use check boxes).

请建议我如何完成此工作?

Please suggest me how to get this done?

预先感谢...

推荐答案

我认为您需要的是<h:selectBooleanCheckbox>.绑定到该组件的值只能是true(有效)或false(无效).它将类似于以下内容:

I think what you need is <h:selectBooleanCheckbox>. The value binded to this component can only be either true (Active) or false (Inactive). It will be something like the following:

<h:selectBooleanCheckbox id="active" value="#{mrBean.active}" >
   <f:ajax render="inactive" listener="#{mrBean.onActiveStatusChange}" />
</h:selectBooleanCheckbox>
<h:selectBooleanCheckbox id="inactive" value="#{mrBean.inactive}" >
   <f:ajax render="active" listener="#{mrBean.onInactiveStatusChange}" />
</h:selectBooleanCheckbox>

@ManagedBean
@RequestScoped
public class MrBean {
   private boolean active;
   private boolean inactive;

   @PostConstruct
   public void prepareMrBean() {
      this.active = true;
   }

   public void onActiveStatusChange() {
      if (active) inactive = false;
   }

   public void onInactiveStatusChange() {
      if (inactive) active = false;
   }
}
