点击h:commandButton时，我正在尝试做一些工作。我正在使用jsf 2.2，因为我正在发送多部分数据。我的表单中有3个 commandButtons ，前2个工作正常，而第3个 commandButton 不工作。
这是我的jsf页面代码：
<h:form id="userSetup" enctype="multipart/form-data" >
<div style=" margin-left: 250px; padding-top: 10px;width: 150px;margin-top: 100px;">
<img id="profile-picture" src="http://www.aspirehire.co.uk/aspirehire-co-uk/_img/profile.svg" height="120" width="120"></img>
<button onclick="addProfilePicture();return false;" class="cff-button" style="margin-top: 10px;margin-left: -10px;white-space: normal;width: 150px;">Add Profile Picture</button>
</div>
<br/><br/>
<h:inputFile id="profilePicture" value="#{uploader.profilePicture}" a:hidden="true" onchange="displayImage(this)">
<f:validator validatorId="imageValidator"></f:validator>
</h:inputFile>
<div class="user-input-div">
<h:messages id="response-message" style="color: red"></h:messages>
<h:inputText id="skills" a:placeholder="Skills" class="cff-inputText " ></h:inputText>
<br/><br/>
<button class="cff-button " style=" white-space: normal" onclick="toggleCertificateInput('#{certificateInput.clientId}',true);return false">Add Certificate</button>
<br/><br/>
<h:panelGroup id="certificate-input" layout="block" binding="#{certificateInput}" a:hidden="true" >
<h:inputText id="certificateName" value="#{uploader.certificateName}" class="cff-inputText" a:required="true" a:placeholder="Certificate Name" binding="#{certificateName}">
<f:validator validatorId="stringValidator"></f:validator>
</h:inputText>
<h:inputText id="certificateLink" value="#{uploader.certificateLink}" class="cff-inputText" a:placeholder="Link" binding="#{certificateLink}">
<f:validator validatorId="urlValidator"></f:validator>
</h:inputText>
<h:commandButton value="Save Certificate" class="cff-button" action="#{uploader.saveCertificate()}" >
<f:ajax execute="certificateName certificateLink response-message" onevent="function hide(data){ if(data.status === 'success'){ toggleCertificateInput('#{certificateInput.clientId}',false) } }" render="userSetup:certificate-output certificateName certificateLink response-message"></f:ajax>
</h:commandButton>
<button class="cff-button" onclick="toggleCertificateInput('#{certificateInput.clientId}',false);return false">Cancel</button>
</h:panelGroup>
<h:panelGroup id="certificate-output-div" binding="#{certificateOutput}">
<h:dataTable var="certificate" id="certificate-output" value="#{uploader.certificates}">
<h:column>
<h:outputText id="certificate-output-name" value="#{certificate.certificateName} " class="certificate-name"></h:outputText>
<h:outputLink id="certificate-output-link" class="cff-link" value=" #{certificate.link}">view certificate</h:outputLink>
<span id="remove" onclick="removeCertificate('#{removeCertificate.clientId}');" class="remove"> ×</span>
<h:commandButton a:hidden="true" binding="#{removeCertificate}" id="removeCertificate" action="#{uploader.removeCertificate(certificate)}" value="Remove" class="cff-button" >
<f:ajax execute=" certificate-output certificate-output-link certificate-output-name " render="userSetup:certificate-output response-message"></f:ajax>
</h:commandButton>
</h:column>
</h:dataTable>
</h:panelGroup>
//This command button is not working
<h:commandButton class="cff-button" action="#{uploader.saveAndContinue()}" value="Save and Continue">
<f:ajax execute="@form"></f:ajax>
</h:commandButton>
</div>
</h:form>
这是我的型号代码：
@ManagedBean(name="uploader")
@ViewScoped
public class userDataUploader {
private String about_Yourself;
private String skills;
private List<Certificates> certificates;
private Part profilePicture;
private String certificateName;
private String certificateLink;
@ManagedProperty(value="#{userData}")
private User userData;
@PostConstruct
public void init(){
certificates = new ArrayList<Certificates>();
}
public List<Certificates> getCertificates() {
return certificates;
}
public void setCertificates(List<Certificates> certificates) {
this.certificates = certificates;
}
public Part getProfilePicture() {
return profilePicture;
}
public void setProfilePicture(Part profilePicture) {
this.profilePicture = profilePicture;
}
public String getAbout_Yourself() {
return about_Yourself;
}
public void setAbout_Yourself(String about_Yourself) {
this.about_Yourself = about_Yourself;
}
public String getSkills() {
return skills;
}
public void setSkills(String skills) {
this.skills = skills;
}
public User getUserData() {
return userData;
}
public void setUserData(User userData) {
this.userData = userData;
}
public String getCertificateName() {
return certificateName;
}
public void setCertificateName(String certificateName) {
this.certificateName = certificateName;
}
public String getCertificateLink() {
return certificateLink;
}
public void setCertificateLink(String certificateLink) {
this.certificateLink = certificateLink;
}
public void addCertificate(){
out.println("about to add new Certificate");
}
public void removeCertificate(Certificates certificate){
out.println("about to remove certificate " + certificate.getCertificateName() + " " + certificate.getLink() );
certificates.remove(certificate);
out.println(certificates.isEmpty());
}
public void saveCertificate(){
Certificates certificate = new Certificates();
certificate.setCertificateName(certificateName);
out.println(certificateName + "\n" + certificateLink);
certificate.setLink(certificateLink);
certificates.add(certificate);
out.println("new certificate has been added");
certificateName = null;
certificateLink = null;
out.println(certificates.isEmpty());
}
public String saveAndContinue(){
out.println("welcome to save and continue function");
out.println(skills);
boolean result = true;
Uploader uploader = new Uploader(userData,certificates,getSkillsArray(),profilePicture);
String returnString = "success";
out.println("about to save all data");
try {
uploader.saveAllData();
} catch (Exception ex) {
out.println(ex);
result = false;
}
if(!result){
returnString = "false";
}
out.println("return string is " + returnString);
return returnString;
}
private String[] getSkillsArray(){
return skills.split(" ");
}
}
有人可以告诉我哪里出错了吗？ THANKYOU。
