使用Primefaces很容易:

It's easy if you use Primefaces:

否则，您可以使用f:ajax标记的onevent属性，该属性接受Java语言函数名称作为值.在AJAX请求期间，将调用该函数三次:在函数参数的状态字段中设置begin，complete和success.

Otherwise you could use the onevent attribute of the f:ajax tag, which accepts a Javascript function name as the value. This function will be called three times during an AJAX request: with begin, complete and success set in the function parameter's status field.

更新:来自Primefaces用户指南:

UPDATE: From the Primefaces users guide:

在第一次加载页面时或在ajax请求完成之后，效果也可以应用于任何JSF组件.下面的示例在ajax请求后对具有脉冲效果的消息进行动画处理.

Effects can also be applied to any JSF component when page is loaded for the first time or after an ajax request is completed. Following example animates messages with pulsate effect after ajax request.

<p:messages id="messages"> 
    <p:effect type="pulsate" event="load"> 
        <f:param name="mode" value="'show'" /> 
    </p:effect>
</p:messages> 
<p:commandButton value="Save" actionListener="#{bean.action}" update="messages"/>
