Orbeon：客戶端的JavaScript API - 找不到元素

Question

我的窗體上有一個小小的xxf:script：

<xf:instance id="fr-form-instance" xxf:exclude-result-prefixes="#all"> 
<form> 
    <section-3> 
     <ctl-input/> 
     <ctl-show/> 
    </section-3> 
</form> 
</xf:instance> 

但是當它：

<xxf:script ev:event="DOMActivate"> 
var msg = ORBEON.xforms.Document.getValue("ctl-input"); 
    window.alert("Input: " + msg); 
</xxf:script> 

應該在以下模型查找​​它運行，它退出時出現以下錯誤：

Uncaught Cannot find control id ctl-input_.extend._findControl

任何想法發生了什麼問題h ERE？

Answer 1

ORBEON.xforms.Document.getValue()取得控件的ID。如果您在Form Builder中創建了該表單，則該ID由您給出的名稱組成，後綴爲-control。所以，你很可能會想打電話：

ORBEON.xforms.Document.getValue("ctl-input-control")
