参考错误:PF 未定义 [英] ReferenceError: PF is not defined

问题描述

我尝试了 PrimeFaces 的 NotificationBar 示例，但它不起作用.我收到以下 JS 错误:

I tried the NotificationBar example of PrimeFaces, however it didn't work. I get the following JS error:

ReferenceError: PF 未定义

ReferenceError: PF is not defined

我想在使用 PF() 函数之前我需要包含一个库，但我不知道是哪个库以及在哪里可以找到它.

I think I need to include a library before using PF() function, but I don't know which library and where can I find it.

推荐答案

JS 函数 PF() 仅从 4.0 开始可用.您显然在使用 PF 3.x.查看展示站点的页脚，目前说它正在运行 PF 4.0.

The JS function PF() is only available since 4.0. You're apparently using PF 3.x. Look at the footer of the showcase site, it's currently saying that it's running PF 4.0.

只需使用 widgetVar.show()，其中 widgetVar 是您在 widgetVar 中指定的小部件变量名称，即 bar 在他们的展示示例中.

Just use widgetVar.show(), where widgetVar is the widget variable name as you specified in widgetVar, which is bar in their showcase example.

<p:commandButton value="Show" onclick="bar.show()" type="button" />  
<p:commandButton value="Hide" onclick="bar.hide()" type="button" />
