我想实现这里写的东西 -如何在命令按钮单击上隐藏和显示 p:panel但看来，hide()不再可用...
正确的做法是什么？
I tried toggle()，但它并没有隐藏它：
我真的需要一些吗panelVisibile支持 bean 的属性和使用visible=#{.panelVisible}?
我正在尝试使用 PrimeFaces 7.0。
项目基于https://github.com/Betlista/joinfaces-maven-jar-example

<p:commandButton onclick="PF('testPanel').hide();" value="Hide Panel" type="button"/>

Result
即使当我尝试过PF('testPanel')在浏览器的控制台中，只有show() and no hide().

测试1视图
package app;
import org.primefaces.PrimeFaces;
import javax.enterprise.context.RequestScoped;
import javax.enterprise.context.SessionScoped;
//import javax.faces.bean.RequestScoped;
import javax.faces.view.ViewScoped;
import javax.inject.Named;
@Named
//@SessionScoped
@ViewScoped
//@RequestScoped
public class Test1View implements Serializable {
boolean panelVisible = false;
public boolean isPanelVisible() {
return panelVisible;
}
public void setPanelVisible(boolean panelVisible) {
this.panelVisible = panelVisible;
PrimeFaces.current().ajax().update("form1:button_panel");
}
}
...但它不起作用=它仅在刷新后隐藏/显示...
最后，我尝试了close()我也发现这正是我正在寻找的东西，但它是具有效果的隐藏：
这不是真的，toggle()是相同的close()对于面板（如果可见）：
结果是（测试6.xhtml)
closeable="true"closeSpeed=0<h:form>
<p:panel id="button_panel" widgetVar="testPanel" closable="true" closeSpeed="0">
<h1>Testing</h1>
</p:panel>
<p:commandButton onclick="PF('testPanel').show()" value="Show Panel" />
<p:commandButton onclick="PF('testPanel').close();" value="Close Panel" />
</h:form>
jQuery: 为此，我定义testPanelJqId作为面板的一个类。

<p:commandButton value="Hide Panel" onclick="jQuery('.testPanelJqId').hide()" />
</h:form>
</h:body>
</html>
它只是感觉不像 PrimeFaces 方法...在这样的设置中，我不需要使用p:panel根本...
