操作方法在菜单项中不工作

动作方法在我的<p:menuitem>中不起作用。我想通过<p:menuitem>的动作方法来改变activeIndex。

下面的代码是在我的页面中使用的模板页上的代码:

<h:form>
    <p:tabMenu activeIndex="#{loginBean.activeindex}">  
        <p:menuitem value="Home" url="Menu.jsf" icon="ui-icon-star" />
        <p:menuitem value="Fabricants" url="/pagess/pagesFabricant/Fabricant.jsf" icon="ui-icon-wrench"   action="#{loginBean.Dirige(1)}" /> 
        <p:menuitem value="Composants" url="/pagess/pagesComposant/Composant.jsf" icon="ui-icon-search"  action="#{loginBean.Dirige(2)}"/> 
        <p:menuitem value="Dossier d'equivalence" url="DEQ.jsf" icon="ui-icon-document" action="#{loginBean.Dirige(3)}"/> 
    </p:tabMenu> 
</h:form>

这是我的豆子:

public class LoginBean {
    private int activeindex;
    public int getActiveindex() {
    return activeindex;
    }
    public void setActiveindex(int activeindex) {
        this.activeindex = activeindex;
    }  
   public void Dirige(int a){
       setActiveindex(a);
   }
}

当我单击任何菜单项时，action方法不会被调用。我做了一些调试，以确保不调用该方法。或者，该方法正在与<p:commandButton>一起工作。

这是模板

当我按下菜单项Fabricant

时，这是Fabricant页面

问题实际上是你的menuitem中的url。
您必须编辑您的Dirige方法。试试以下命令:

public String Dirige(int a){
   setActiveindex(a);
   if (a == 1) {
      return "/pagess/pagesFabricant/Fabricant.jsf";
   }else{
      if (a == 2) {
         return "/pagess/pagesComposant/Composant.jsf";
      }else{
         ...
      }
   }
}

，在你的模板中，你必须删除url-Tags:

<h:form>
    <p:tabMenu activeIndex="#{loginBean.activeindex}">  
        <p:menuitem value="Home" url="Menu.jsf" icon="ui-icon-star" />
        <p:menuitem value="Fabricants" icon="ui-icon-wrench"   action="#{loginBean.Dirige(1)}" /> 
        <p:menuitem value="Composants" icon="ui-icon-search"  action="#{loginBean.Dirige(2)}"/> 
        <p:menuitem value="Dossier d'equivalence" icon="ui-icon-document" action="#{loginBean.Dirige(3)}"/> 
    </p:tabMenu> 
</h:form>
