How do you pass a value into an ajax listener primefaces
提问by Landister
So I have
所以我有
<p:ajax event="tabChange" listener="#{refriedBean.onTabChange}" />
But I want to pass in the tabChange event AND an extra value that is stored on the page
但我想传入 tabChange 事件和存储在页面上的额外值
public void onTabChange(TabChangeEvent event, Object obj)
How would one go about doing this?
怎么做呢？

You can replace argument objwith additional property in bean and set needed value to this property on ajax request:
您可以obj使用 bean 中的附加属性替换参数，并在 ajax 请求中为该属性设置所需的值：
<p:ajax event="tabChange" listener="#{refriedBean.onTabChange}">
<f:setPropertyActionListener target="#{refriedBean.additionalProperty}" value="value_here"/>
</p:ajax>
