我正在学习如何使用primefaces框架。我设置了一个用于制作示例的项目，但在使自动完成组件正常工作时遇到了一些麻烦。我想根据玩家来源显示此自动完成组件上“玩家”的提示，但未显示提示。我没有关于Ajax的经验，也没有关于bean的经验，显然我做错了。感谢您的帮助！

最佳答案
您想获得其他信息的工具提示吗？有一个例子：http://www.primefaces.org/showcase/ui/autoCompleteItemtip.jsf
虽然itemValue是在bean中设置的值，而itemLabel是在下拉菜单中显示的文本，但对于工具提示，您需要使用facet name="itemtip"：
<p:autoComplete value="#{autoComplBean.selectedPlayer}"
completeMethod="#{autoComplete.complete}" var="p"
itemLabel="#{p.name}" itemValue="#{p}" dropdown="true">
<f:facet name="itemtip">
#{p.name} #{p.surname} (#{p.age})
</f:facet>
</p:autoComplete>
