Question

当用户从selectOneMenu中选择“Check”选项时，我希望'可见'bankName inputtext和chequeNumber输入文本，否则看不见。

<table border="1" id="invoiceData">
        <tr>
            <td valign="bottom" rowspan="6"><p:outputLabel
                    style="font-weight: bold;" value="Email" /><br /> <p:inputText
                    value="#{invoiceBean.email}" autocomplete="off" /></td>
        </tr>
        <tr>
            <td><p:outputLabel style="font-weight: bold;"
                    value="Invoice No" /><br /> <p:inputText
                    value="#{invoiceBean.invoiceNumber}" required="true"
                    label="Invoice Number" requiredMessage="Invoice Number Required" /></td>
            <td><p:outputLabel style="font-weight: bold;" value="Date" /><br />

                    value="#{invoiceBean.termsOfdelivery}" cols="43" /></td>
        </tr>
    </table>

当用户选择“检查”选项时，输入文本将可见，否则不可见。

解决方案使用SelectOneRedio标签，布局属性和添加panelGroup标签

<h:panelGroup id="inputs">
        <table border="1" id="invoiceData">
            <tr>
                <td valign="bottom" rowspan="6"><p:outputLabel
                        style="font-weight: bold;" value="Email" /><br /> <p:inputText
                        value="#{invoiceBean.email}" autocomplete="off" /></td>
            </tr>
            <tr>
                <td><p:outputLabel style="font-weight: bold;"
                        value="Invoice No" /><br /> <p:inputText
                        value="#{invoiceBean.invoiceNumber}" required="true"
