以下是PrimeFaces展示的关于<p:growl>
标记的示例代码。在此示例中,当您单击&#34;保存&#34;按钮,出现两条消息&#34;成功&#34;和#34; SecondMessage&#34;。
这link就是我所说的。
这是PrimeFaces Showcase的示例代码
<h:form>
<p:growl id="growl" showDetail="true" sticky="true" />
<p:panel header="Growl">
<h:panelGrid columns="2" cellpadding="5">
<p:outputLabel for="msg" value="Message:" />
<p:inputText id="msg"
value="#{growlView.message}"
required="true" />
</h:panelGrid>
<p:commandButton value="Save"
actionListener="#{growlView.saveMessage}"
update="growl" />
</p:panel>
</h:form>
来自PrimeFaces的bean GrowlView.java
再次展示。
@ManagedBean
public class GrowlView {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public void saveMessage() {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage("Successful", "Your message: " + message) );
context.addMessage(null, new FacesMessage("Second Message", "Additional Message Detail"));
}
}
我的问题是,我怎样才能做出成功的&#34; message&quot; sticky = true,SecondMessage&s; sticky = false?
我尝试用两个<p:growl>
标签来改变第二个咆哮位置和粘性。但是如果你关闭第一个咆哮,第二个咆哮的位置不会像PrimeFaces Showcase示例那样改变
答案 0 :(得分:1)
这是修改后的示例代码:
<h:form id="growlForm">
<p:growl id="growl1" showDetail="true" sticky="true" />
<p:growl id="growl2" showDetail="true" sticky="false" />
<p:panel header="Growl">
<h:panelGrid columns="2" cellpadding="5">
<p:outputLabel for="msg" value="Message:" />
<p:inputText id="msg" value="#{growlView.message}"
required="true" />
</h:panelGrid>
<p:commandButton value="Save"
actionListener="#{growlView.saveMessage}" update="growl1 growl2" />
</p:panel>
</h:form>
saveMethod:
public void saveMessage() {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage("growlForm:growl1", new FacesMessage("Successful", "Your message: " + message) );
context.addMessage("growlForm:growl1", new FacesMessage("Second Message", "Additional Message Detail"));
context.addMessage("growlForm:growl2", new FacesMessage("Successful 2", "Your message: " + message) );
context.addMessage("growlForm:growl2", new FacesMessage("Second Message 2", "Additional Message Detail"));
}
在这种情况下,我发现了一些奇怪的东西。一开始,两个咆哮都在saveMethod
中添加了四条消息。过了一会儿(6秒,life
属性的默认值),来自growl1
的所有消息都按预期消失。
我不知道为什么两个咆哮最终都会收到4条消息。我搜索了现有的咆哮问题,并发现了与multiple grows相关的问题。
看一下生成的html。你有同样的事吗?
