我有以下的code：

<h:commandLink action="#{testBean.showSomething}">
    Do Stuff
</h:commandLink>

至极我想要做什么（变化testBean这个状态并重新加载它会显示一组不同的div，网页，因为他们的渲染的属性） 现在我想使用Ajax来做到这一点，所以我这样做：

wich does what i want (change the state of testbean and reload the page which will show a different set of divs. because of their "rendered" properties) Now I want to use ajax to accomplish this so i did this:

<h:commandLink action="#{testBean.showSomething}">
    <f:ajax event="click" render=":content" />
    Do Stuff
</h:commandLink>

然而，这将导致showSomething方法甚至不被调用。 恕我直言，我想要做的是相当简单的，但我不能为我的生活弄清楚如何做到这一点。

However this causes the showSomething method to not even be called. IMHO what i want to do is rather simple but i cant for the life of me figure out how to do it.

推荐答案

您需要使用事件=动作，而不是事件=点击。你甚至可以完全忽略它。这也就是默认事件的＆LT; F：。AJAX＆GT; 监听嵌套在一个 UICommand 组件时，在

You need to use event="action" instead of event="click". You could even omit it altogether. It's namely the default event the <f:ajax> is listening on when nested in an UICommand component.

<h:commandLink action="#{testBean.showSomething}">
    <f:ajax render=":content" />
    Do Stuff
</h:commandLink>
