Spring WebFlow2 Javascript仅适用于第一个单选按钮

如果用户点击其中一个单选按钮，我正在尝试使用WebFlow2附带的Spring JavaScript来提交带有转换值的页面。

我使用onclick和onchange在页面上插入了我的javascript，它只在第一个单选按钮被选中时才有效。我不知道为什么，但我想我尝试了一切......有人可以告诉我这是否是Spring JavaScript的问题。

JSP：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

Answer 1

你有：

<form:radiobutton value="B" path="row" id="rowBtn" />Row: B<BR>
<form:radiobutton value="A" path="row" id="rowBtn" />Row: A<BR>

您的两个单选按钮具有相同的元素ID。 AjaxEventDecoration基于该elementId进行查找。它假设它在页面上是唯一的，并且它不期望具有相同id的多个元素。你应该给第二个radiobutton另一个id。

您可能只需重新输入该ID的AjaxEventDecoration。如果Spring.AjaxEventDecoration允许你基于元素类（而不是elementId）做类似的事情，也许你可以这样做，而不是复制当前的Spring.AjaxEventDecoration片段。

Spring WebFlow2 Javascript只能在第一个单选按钮上工作
