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.
JS 功能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。
Just use widgetVar.show(), where widgetVaris the widget variable name as you specified in widgetVar, which is barin their showcase example.
