我正在使用远程命令按钮来执行 bean 级别的方法。但是我的命令按钮不起作用。
我在下面附上我的代码:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<ui:composition template="/layouts/BasicTemplate.xhtml">
<ui:define name="content">
<div class="container">
<script>
function doAlert(s)
{
if(s=="true")
{
alert(s);
rc();
alert('hi i am');
}
else
{
alert("Wrong Finger Print");
}
}
</script>
<h:form class="form-horizontal" id="myform" >
<div class="row">
<h:messages />
<h:panelGrid columns="3" cellpadding="4" border="0" columnClasses="control-label">
<h:outputText value="Username :" />
<h:inputText id="username" value="#{loginBean.login}" label="username" style="width: 200;" />
<p:watermark for="username" value="Username" ></p:watermark>
<h:outputLabel for="password" value="Password :" />
<h:inputSecret id="password" value="#{loginBean.password}" label="password" style="width: 200;"/>
<p:watermark for="password" value="Password"></p:watermark>
<p:spacer></p:spacer>
<!-- <p:commandButton value="Login" action="#{loginBean.logMeIn}" widgetVar="mybutton" /> -->
<p:commandButton id="loginButton" value="Login" action="#{loginBean.logMeIn}" widgetVar="mybutton" disabled="#{!loginBean.enabled}"/>
<p:remoteCommand name="rc" update="loginButton" actionListener="#{loginBean.enableButton}" />
<p:spacer></p:spacer>
<h:outputText value="#{loginBean.enabled}"></h:outputText>
<applet id="fingureprintapplet" name="fingureprint" codebase="classes" code="fingerprintntscanner.MyClassApplet.class" archive="#{facesContext.externalContext.requestContextPath}/FIngerprintntScanner.jar,#{facesContext.externalContext.requestContextPath}/lib/NBioBSPJNI.jar" width="300" height="400">
</applet>
</h:panelGrid>
</div>
</h:form>
</div>
</ui:define>
</ui:composition>
我的 bean 是:
@ManagedBean(name = "loginBean")
@SessionScoped
public class LoginBean implements Serializable {
private static final long serialVersionUID = 1L;
private String login;
private String password;
private boolean enabled;
@ManagedProperty(value = "#{authenticationService}")
private AuthenticationService authenticationService; // injected Spring defined service for bikes
public String logMeIn() {
boolean success = authenticationService.login(login, password);
if (success){
return "/faces/pages/home.xhtml?faces-redirect=true"; // return to application but being logged now
}
else{
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Login or password incorrect."));
return "/faces/login.xhtml";
}
}
public String logout(){
System.out.println("chandan");
authenticationService.logout();
return "/faces/pages/home.xhtml?faces-redirect=true";
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public void setAuthenticationService(AuthenticationService authenticationService) {
this.authenticationService = authenticationService;
}
public void enableButton() {
System.out.println("chandan");
enabled = true;
}
public boolean isEnabled(){
System.out.println("value is");
return enabled;
}
public void setEnabled(boolean enabled) {
System.out.println("value is sdgsdg");
this.enabled = enabled;
}
请检查为什么我的远程命令不起作用。
最佳答案
在 remoteCommand 上使用 process="@this" 和 partialSubmit="true"。
关于jsf - PrimeFaces 远程命令未调用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28338444/
