如何在提交按钮上获取 amx 迭代器所有文本框值

Question

我想在单击提交按钮时获取所有文本框、选择框、单选按钮值。所有输入元素都使用 amx:iterator 进行迭代。我在下面分享了 amx 代码。

输入字段根据服务器的响应是动态的。

提前致谢。

按照上面给出的代码，

您可以使用<amx:commandButton> 中的属性<amx:setPropertyListener> 将您想要获取的任何值分配给相应bean 类中的变量。

例如：<amx:setPropertyListener from="#{row.questionList.bindings.qid.inputValue}" to="#{pageFlowScope.questionId}" type="action">

如果您正在查看数据库中的值，最好在 actionListener 中查询数据库中的值以获得更好的性能。
