Invoke <h:commandLink> action method using <f:ajax>
提问by martijnve
I have the following code:
我有以下代码：
<h:commandLink action="#{testBean.showSomething}">
Do Stuff
</h:commandLink>
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:
做了我想要的（更改 testbean 的状态并重新加载页面，该页面将显示一组不同的 div。因为它们的“渲染”属性）现在我想使用 ajax 来完成这个，所以我这样做了：
<h:commandLink action="#{testBean.showSomething}">
<f:ajax event="click" render=":content" />
Do Stuff
</h:commandLink>
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.
然而，这会导致 showSomething 方法甚至不被调用。恕我直言，我想做的很简单，但我一生都无法弄清楚如何去做。

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 UICommandcomponent.
您需要使用event="action"而不是event="click". 你甚至可以完全省略它。即<f:ajax>嵌套在UICommand组件中时正在侦听的默认事件。
<h:commandLink action="#{testBean.showSomething}">
<f:ajax render=":content" />
Do Stuff
</h:commandLink>
