Question

似乎存在与xf:triggers中嵌入的fr:section相关的问题，请参阅以下两个示例表单。

任何已知的解决方法？

触发器未嵌入fr：section - 工作正常

嵌入在fr：section中的

触发器 - 不起作用

只要xf:trigger嵌入fr:section，Orbeon JavaScript API就不再找到控件message了。除了额外的fr:section之外，这是相同的基本形式。

Answer 1

这是因为该部分是XBL控件，当您的控件位于XBL控件内时，在生成的HTML中，容器的ID将作为控件ID的前缀添加。所以你可以使用：

var messageControl = ORBEON.jQuery('*[id $= "message"]')[0];
alert(ORBEON.xforms.Document.getValue(messageControl));

有关详情，请参阅how to use getValue() and setValue() on forms created with Form Builder上的文档部分。

Orbeon JavaScript API - 从fr：section中访问控制值？
