Javascript破坏了基于PrimeFaces的页面中的导航

Javascript破坏了基于PrimeFaces的页面中的导航,javascript,ajax,jsf,primefaces,Javascript,Ajax,Jsf,Primefaces,我使用了一些第三方连接监控代码(由Denis Radin编写),它与我的页面上的导航元素进行了交互,我根本不理解。我希望有人能解释一些可能的原因,这样我就能更好地纠正这个问题 当Javascript代码就位时,我有一个PrimeFacesCommandButton元素,它开始间歇性地失败;有时它会把我带到我想要的页面,有时它什么也不做 <p:commandButton icon="icon-back" value="#{appMsgs['button
