Question

我的<p:menuitem>中的操作方法不起作用。我想通过activeIndex的操作方法更改<p:menuitem>。

以下代码是我的网页中使用的模板页面上的代码：

<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);
   }
}

当我点击任何菜单项时，不会调用action方法。我做了一些调试，以确保不调用该方法。或者，该方法正在使用<p:commandButton>。

这是模板

问题实际上是url中的menuitem 您必须编辑Dirige方法。请尝试以下方法：

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{
         ...
      }
   }
}

在您的模板中，您必须删除网址标签：

<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>

在p：menuitem中无法使用的操作方法
