如何使用Dojo（dijit）在Spring WebFlow项目中创建所需的复选框。

我想知道在提交以下页面时如何设置复选框。

如果用户没有单击其中一个复选框选项，我不希望提交工作。谢谢。用户需要单击或同时选中两个复选框才能提交页面。

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



    <style type="text/css" media="screen">
     @import url("<c:url value="/resources/dojo/resources/dojo.css"/>");
     @import url("<c:url value="/resources/dijit/themes/claro/claro.css"/>");
    </style>     

    <script djconfig="parseOnLoad: true"
     src="<c:url value="/resources/dojo/dojo.js"/>" type="text/javascript"></script>
    <script type="text/javascript"

            <script type="text/javascript">
                Spring.addDecoration(new Spring.ValidateAllDecoration({

我让它工作了...我必须更改我的jsp以匹配以下

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

<style type="text/css" media="screen">
 @import url("<c:url value="/resources/dojo/resources/dojo.css"/>");
 @import url("<c:url value="/resources/dijit/themes/claro/claro.css"/>");
</style>     

<script djconfig="parseOnLoad: true"
 src="<c:url value="/resources/dojo/dojo.js"/>" type="text/javascript"></script>
<script type="text/javascript"
 src="<c:url value="/resources/spring/Spring.js" />"> </script>
