如何实现简单的添加/删除动态<rich:tabPanel>
?
(我见过有人问这个问题,所以我想发布一个简单实现的问答)
该实现有 3 个自定义类:
代码是:
内容:
public class Content {
String name;
String job;
String dept;
public Content() {
name = "John Doe";
job = "None";
dept = "None";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public String getDept() {
return dept;
}
public void setDept(String dept) {
this.dept = dept;
}
}
选项卡项:
public class TabItem {
UITab component;
Content content;
public TabItem() {
component = new UITab();
content = new Content();
}
public UITab getComponent() {
return component;
}
public void setComponent(UITab tab) {
this.component = tab;
}
public Content getContent() {
return content;
}
public void setContent(Content content) {
this.content = content;
}
}
我的标签:
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.enterprise.context.SessionScoped;
import javax.inject.Named;
@Named
@SessionScoped
public class MyTabs implements Serializable {
private List<TabItem> tabs;
public MyTabs() {
tabs = new ArrayList<TabItem>();
}
@PostConstruct
private void init() {
createTab();
createTab();
createTab();
}
public void createTab() {
TabItem tab = new TabItem();
tab.getComponent().setId("Tab" + (tabs.size()+1));
tab.getComponent().setHeader("Tab " + (tabs.size()+1));
tab.getContent().setName("John Doe " + (tabs.size()+1));
tab.getContent().setJob("Salesman " + (tabs.size()+1));
tab.getContent().setDept("Sales " + (tabs.size()+1));
tabs.add(tab);
}
public void removeTab(TabItem tab) {
tabs.remove(tab);
}
public List<TabItem> getTabs() {
return tabs;
}
public void setTabs(List<TabItem> tabs) {
this.tabs = tabs;
}
}
tabview.xhtml:
<h:commandLink value="Add Tab"
actionListener="#{myTabs.createTab()}"/>
<rich:tabPanel switchType="client">
<c:forEach items="#{myTabs.tabs}" var="tab">
<rich:tab value="#{tab.component}">
<f:facet name="header">
<h:outputLabel value="#{tab.component.header}"/>
<h:commandLink value=" X" actionListener="#{myTabs.removeTab(tab)}"/>
</f:facet>
<h:panelGrid columns="2">
<h:outputLabel value="Name: "/>
<h:outputLabel value="#{tab.content.name}"/>
<h:outputLabel value="Dept: "/>
<h:outputLabel value="#{tab.content.dept}"/>
<h:outputLabel value="Job: "/>
<h:outputLabel value="#{tab.content.job}"/>
</h:panelGrid>
</rich:tab>
</c:forEach>
</rich:tabPanel>
