java - 当用户正确插入凭据时，为什么登录对话框不会消失？(JSF 2.0。)

Question

我正在使用一些 primefaces 组件实现应用程序管理的登录机制。当正确输入凭据时，我成功保存了用户状态，并且在错误输入时使对话框抖动。

问题是，当正确输入凭据时，该对话框也应该消失。而不是那样。当凭据正确时，对话框会抖动并且不会自动消失。我该如何解决这个问题？

这是 JSF 页面的一部分，其中包含我提到的对话框:

<p:dialog id="dialog" header="Login" widgetVar="dlg" modal="true"
        width="400" resizable="false" draggable="false" fixedCenter="true">
        <h:form>
            <h:panelGrid columns="2" cellpadding="5">
                <h:outputLabel for="username" value="Em@il: *" />
                <p:inputText value="#{securityController.email}" id="email"
                    required="true" label="email" validator="#{securityController.validateEmail}"/>


                <h:outputLabel for="password" value="Password: * " />
                <h:inputSecret value="#{securityController.password}" id="password"
                    required="true" label="password" validator="#{securityController.validatePassword}"/>

                <f:facet name="footer">
                    <p:commandButton value="Login" update="growl"                       
                         oncomplete="handleLoginRequest(xhr, status, args)"
                             actionListener="#{securityController.logIn()}"/>
                </f:facet>
            </h:panelGrid>
        </h:form>
    </p:dialog>

    <script type="text/javascript">  
function handleLoginRequest(xhr, status, args) {  
    if(args.validationFailed || !args.loggedIn) {  
        jQuery('#dialog').parent().effect("shake", { times:3 }, 100);  
    } else {  
        dlg.hide();  
        jQuery('#loginLink').fadeOut();  
    }  
}  
</script> 

这是执行部分验证的托管 bean:

@ManagedBean
@RequestScoped
public class SecurityController {
@EJB
private IAuthentificationEJB authentificationEJB;
private String email;
private String password;
private String notificationValue;   

public void logIn() {
    if(authentificationEJB.saveUserState(email, password)) {
        notificationValue = "Dobro dosli";
    }   
}

public void validateEmail(FacesContext context, UIComponent validate,
        Object value) {
    String inputFromField = (String) value;
    String simpleTextPatternText = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
    Pattern textPattern = null;
    Matcher emailMatcher = null;
    textPattern = Pattern.compile(simpleTextPatternText);
    emailMatcher = textPattern.matcher(inputFromField);
    if (inputFromField.length() >= 30) {
        FacesMessage msg = new FacesMessage(
                "Pre dugacak email(Ne dozvoljeno)");
        throw new ValidatorException(msg);

    }

    if (inputFromField.length() <= 0) {
        FacesMessage msg = new FacesMessage("Zaboraviliste email adresu");
        throw new ValidatorException(msg);

    }

    if (!emailMatcher.matches()) {
        FacesMessage msg = new FacesMessage(
                "Ne ispravan email. Napisiti email u ispravnom obliku. (Np: markomarkovic@mail.com)");
        throw new ValidatorException(msg);
    }       
}

public void validatePassword(FacesContext context, UIComponent validate,
        Object value) {
    String inputFromField = (String) value;
    String simpleTextPatternText = "^[a-zA-Z0-9]+$";
    Pattern textPattern = null;
    Matcher passwordMatcher = null;
    textPattern = Pattern.compile(simpleTextPatternText);
    passwordMatcher = textPattern.matcher(inputFromField);      

    if (inputFromField.length() <= 0) {
        FacesMessage msg = new FacesMessage("Zaboraviliste lozinku");
        throw new ValidatorException(msg);

    }

    if (!passwordMatcher.matches()) {
        FacesMessage msg = new FacesMessage(
                "Lozinka samo moze da zadrzi slova od A do Z i broja od 0 do 9");
        throw new ValidatorException(msg);
    }       
}

public String getEmail() {
    return email;
}

public String getPassword() {
    return password;
}

public void setEmail(String email) {
    this.email = email;
}

public void setPassword(String password) {
    this.password = password;
}

public String getNotificationValue() {
    return notificationValue;
}

public void setNotificationValue(String notificationValue) {
    this.notificationValue = notificationValue;
}

我解决了这个问题，我修改了 login() 方法，如下所示:

public void logIn() {
    RequestContext context = RequestContext.getCurrentInstance();          
    boolean loggedIn = false;
    if(authentificationEJB.saveUserState(email, password)) {
        notificationValue = "Dobro dosli";
         loggedIn = true;             
         context.addCallbackParam("loggedIn", loggedIn);
    }   
}

我对 javascript 不太了解，但我想该对话框发现了来自支持 bean 的某种响应消息。

无论如何，谢谢:)
