Question

我需要驗證<p:spinner>值是否在設定範圍之間。

<p:spinner id="minutes" min="0" max="1000" value="#{printerSettings.t}" size ="1"> 
    <f:validateLongRange minimum="0" maximum="1000" /> 
    <p:ajax update="NewTime"/> 
</p:spinner> 
<h:message for="minutes" style="color:red" /> 

和

<p>Number of copies (Max of 50) : 
    <p:spinner id ="Copies" min="1" max="50" value="#{printerSettings.p}" size ="1"> <!-- allows the user a choice of up to 50, this is more than enough for any situation, if needed this can be removed or raised --> 
     <p:ajax update="p"/> 
     <f:validateLongRange minimum="1" maximum="50" /> 
    </p:spinner> 
    <div class="whiteSpace"/> 
    <h:outputText value="Copies that will be printed: &nbsp; #{printerSettings.p}" id="p"/> 

    <h:message for="Copies" style="color:red" /> 
</p> 

這是以前的工作，但現在沒有驗證發生，沒有錯誤等等，這是怎麼造成的，我該怎麼解決呢？

<div id="site_content"> 
     <div id="content"> 
      <h:body> 


       <h:form onsubmit="return validateForm()"> 
        <p> 

        In how many minutes time would you like to have your job sent to the printer ? 
        <div class="whiteSpace"/> 
        <p:spinner id="minutes" min="0" max="1000" value="#{printerSettings.t}" size ="1"> 
         <p:ajax update="NewTime"/> 
         <f:validateLongRange minimum="1" maximum="1000" /> 
        </p:spinner> 

        <h:message for="minutes" style="color:red" /> 

        <br></br> 
        <br></br> 

        The time the print job will be sent to the printer will be : 
        <!--<p:button actionListener="{otherBean.setTValue(printerSettings.t)}" value="Set Val" /> Currently causing an error --> 
        <br></br> 
        <h:outputText value="#{printerSettings.getNewTime()}" id="NewTime"/> 
        <br></br> 
        <br></br> 
        <p:commandButton type="submit" action="#{email.mail(printerSettings.t, printerSettings.p, printerSettings.paperSize, printerSettings.duplex, printerSettings.orienation, printerSettings.printer)}" onclick="Thankyou()" value="Print" /> 

<p:button outcome="index" value="Homepage" icon="ui-icon-home"> 
        </p:button> 

       </h:form> 
      </h:body> 
     </div> 
    </div> 
    <script type="text/javascript"> 

        function Thankyou() 
        { 
         alert("Sent to the printing holding queue, you may close this app now or carry on using this app, your work will still print out "); 
         //location.href = 'index.xhtml'; 

        } 

是可以嗎？我可以發佈，如果需要更多的代碼，在我的評論說，驗證似乎是工作，它只是現在顯示在所有

   <p:commandButton type="submit" update ="minutes2 Copies2" action="#{email.mail(printerSettings.t, printerSettings.p, printerSettings.paperSize, printerSettings.duplex, printerSettings.orienation, printerSettings.printer)}" onclick="Thankyou()" value="Print" />

你確認並提交錯誤的消息ajax的形式，但你無處指示JSF更新ajax響應的消息組件。他們不會自行更新。

您需要給消息組件一個ID並在ajax更新中引用它們。

E.g.

<h:message id="foo" ... /> 

和

<p:ajax ... update="foo" /> 

和

<p:commandButton ... update="foo" /> 

您可以根據需要指定spaceseparated多個ID。

<p:commandButton ... update="foo bar" />
