error: /index.xhtml @30,146 <f:ajax> 'valueChange' is not a supported event for HtmlForm. Please specify one of: click, dblclick, keydown, etc

Question

我这里有可以正常工作的代码：

<h:selectOneMenu value="#{customer.selectedname}" id="ulist">
                        <f:selectItems value="#{customer.allCustomers}"/>
                        <f:ajax event="change" render="cid fname lname email sd" listener="#{customer.fullInfo}"/>
                    </h:selectOneMenu>

但是，当我在不同的项目中实施它时，它不起作用。下面是代码：

<td><h:outputLabel value="No Polisi:"/></td>
                            <td><h:inputText value="#{motor.VNOPOL}" id="VNOPOL"/></td>
                         <f:ajax event="valueChange" render="VIDPROSPEK VFRAMENUM VENGINENUM VTHNPROD NKMSERVICE " listener="#{motor.fullInfo}"/>

我收到一个错误：

/index.xhtml @30,146 'valueChange' is not a supported event for HtmlForm. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

在 VNOPOL 中输入后，我应该如何实现才能显示所有信息？

Answer 1

JSF ajax 仅支持 JSF 组件，您没有在组件内包含 <f:ajax>

您应该如下更改代码

<td>
   <h:inputText value="#{motor.VNOPOL}" id="VNOPOL">
       <f:ajax event="your event" render="your elements" listener="your listener"/>
   </h:inputText>
</td>

请注意 <f:ajax> 现在在 <h:inputText>

中
