我动态在我的页面中包含一个主要项目风格的xhtml页面。 在第一次请求我可以在包含页面上找到facesmessgae。 然后输入ajax验证不起作用，没有验证，不起作用。 commandButton不起作用。
包含页面
.ui-slidemenu-content {height：300px; } $（function（）{ $（ “＃addfoodtogg”）切换（）。 }）;
</h:head>
<h:body>
<ui:include src="../header.xhtml"/>

答案 0 :(得分：0)

<p:commandButton id="addacate" process="@this" value="添加" actionListener="#foodManagerController.addFood()}" ajax="true"/>
