java - 在 XHTML 表单/Java PrimeFaces 中的多个按钮上使用 primefaces 对话框

Question

我有一个问题，我对 primefaces 和 JSF 都很陌生，可能是我缺乏知识，但我还找不到答案，我有 XHTML-s，在主按钮上我有几个按钮，我写了一个反馈对话框，告诉操作成功，以及操作的名称。

出现对话框，看起来不错，但消息始终是我在最后一个按钮上指定的内容。也许我误解了这个概念，任何人都可以帮助我我做错了什么吗？

这里是代码:

bean

@ManagedBean
@ViewScoped
public class ActionSuccessController extends AbstractAction implements
    Serializable {

public String setParam(String actionName) {
    ResourceBundle messageBundle = ResourceBundle
            .getBundle("hu.avhga.web.partner.messages");
    description = messageBundle.getString("actionSuccess");
    this.actionName = actionName;
    return "";
}
...

我有按钮的主 XHTML

...
                            <p:commandButton id="lock"
                            value="#{msg['PartnerAdmin.button.lock']}" 
                            action="#{partnerAccountAdminAction.lock}" 
                            update=":partnerAccountAdminForm :actionSuccessForm"
                            disabled="#{partnerAccountAdminAction.disabledButtonMap.get('LOCK')}"
                            rendered="#{partnerAccountAdminAction.passwordAdmin}"
                            styleClass="gold"
                            onclick="#{actionSuccessController.setParam(msg['PartnerAdmin.button.lock'])}"
                            oncomplete="usersTableWidget.filter();actionSuccessDialogVar.show();"/>

                        <p:commandButton id="unlock"
                            value="#{msg['PartnerAdmin.button.unlock']}" 
                            action="#{partnerAccountAdminAction.unlock}"
                            update=":partnerAccountAdminForm :actionSuccessForm"
                            disabled="#{partnerAccountAdminAction.disabledButtonMap.get('UNLOCK')}"
                            rendered="#{partnerAccountAdminAction.passwordAdmin}"
                            styleClass="gold"
                            onclick="#{actionSuccessController.setParam(msg['PartnerAdmin.button.unlock'])}"
                            oncomplete="usersTableWidget.filter();actionSuccessDialogVar.show();"/>

                        <p:commandButton id="suspend"
                            value="#{msg['PartnerAdmin.button.suspend']}" 
                            action="#{partnerAccountAdminAction.suspend}"
                            update=":partnerAccountAdminForm :actionSuccessForm"
                            disabled="#{partnerAccountAdminAction.disabledButtonMap.get('SUSPEND')}"
                            rendered="#{partnerAccountAdminAction.userAdmin}"
                            styleClass="gold"
                            onclick="#{actionSuccessController.setParam(msg['PartnerAdmin.button.suspend'])}"
                            oncomplete="usersTableWidget.filter();actionSuccessDialogVar.show();"/>

                        <p:commandButton id="remove"
                            value="#{msg['PartnerAdmin.button.remove']}" 
                            action="#{partnerAccountAdminAction.remove}"
                            update=":partnerAccountAdminForm :actionSuccessForm"
                            disabled="#{partnerAccountAdminAction.disabledButtonMap.get('REMOVE')}"
                            rendered="#{partnerAccountAdminAction.userAdmin}"
                            styleClass="gold"
                            onclick="#{actionSuccessController.setParam(msg['PartnerAdmin.button.remove'])}"
                            oncomplete="usersTableWidget.filter();actionSuccessDialogVar.show();"/>
...

此后我导入了以下 XHTML:

<p:dialog id="actionSuccessDialogId" header="#{actionSuccessController.actionName}"
        styleClass="dialog" closable="false"
        widgetVar="actionSuccessDialogVar" modal="true" appendToBody="true" dynamic="true"
        resizable="false" showEffect="fade" hideEffect="explode">
    <h:form id="actionSuccessForm" style="text-align:center;">
        <h:outputText value="#{actionSuccessController.description}" />
        <br />
        <br />
        <p:commandButton id="okButtonId" value="#{msg['Common.ok']}"
                        onclick="actionSuccessDialogVar.hide()" 
                        type="button" />
    </h:form>
</p:dialog>

我确信这些“setParam”总是运行，对我来说这似乎没有理由。那么问题又来了，为什么我总是得到“删除”属性的名称。是因为ajax吗？或者因为当我点击某个地方时这些都会运行？我有一点困惑。提前致谢!

简而言之，onclick 无法调用这样的 setter。您似乎想要将参数传递给您的 bean 操作，对吧？在这种情况下，您需要使用 f:setPropertyActionListener 标记。所以你的按钮看起来像这样:

<p:commandButton id="unlock"
                    value="#{msg['PartnerAdmin.button.unlock']}" 
                    action="#{partnerAccountAdminAction.unlock}"
                    update=":partnerAccountAdminForm :actionSuccessForm"
                    disabled="#{partnerAccountAdminAction.disabledButtonMap.get('UNLOCK')}"
                    rendered="#{partnerAccountAdminAction.passwordAdmin}"
                    styleClass="gold"
                    oncomplete="usersTableWidget.filter();actionSuccessDialogVar.show();">
      <f:setPropertyActionListener target="#{actionSuccessController.param}" value="#{msg['PartnerAdmin.button.lock']}" />
</p:commandButton>

f:setPropertyActionListener 使用 value 属性中指定的值调用目标中指定的 setter。
