       <form:form name="batchForm" method="post" action="/video/list.html">
       <input type="hidden" name="p" value="<c:out value="$...{videoList.p}"/>"/>//从action取得p的值
     </form:form>
      public ModelAndView list(HttpServletRequest request,HttpServletResponse response) ...{
        int page = ServletRequestUtils.getIntParameter(request, "p", 1);//通过超连接取得p的参数值
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("p", page);
        return new ModelAndView(listView, "videoList", map);
     }

2.在javascript里面实现不同连接的表单提交
 

<form id="messageForm" name="messageForm" method="post" onSubmit="return
      onMessageFormSubmit(<c:out  value="$...{param.type}"/>)"> 
       <input type="hidden" name="method" value="delete"/>
       <input type="hidden" name="type" value="<c:out value="$...{param.type}"/>" />
    </form>
    <script type="text/javascript">
        function onMessageFormSubmit(type) ...{
            if(type == 0) ...{
                document.messageForm.action = '/commend/special/list.html';
            }
            if(type == 1)...{
                document.messageForm.action = '/special/list.html';
            }
         }
         Form.focusFirstElement($('messageForm'));
   </script>

3.通过编辑页面的提交给action="/special/edit.html"既对应的onsubmit方法返回给前一页面,注意删除按钮不应提交
 

<c:set var="buttons">
<input type="submit" class="button" name="audited" onclick="bCancel=false" value="<fmt:message key
    ="button.audited"/>"/>
<input type="button class="button" onclick="location.href='/special/list.html?method=find&from=edit'"
     value="<fmt:message   key="button.delete"/>"/>
<input type="submit" class="button" name="cancel" onclick="bCancel=true" value="<fmt:message
      key="button.back"/>"/>
 </c:set>
 <form:form commandName="special" method="post" action="/special/edit.html" id="specialForm" >
    <input type="hidden" name="type" value="<c:out value="$...{param.type}" />" />
    <p class="buttonBar bottom">
        <c:out value="${buttons}" escapeXml="false" />
    </p>
   </form:form>

4.jsp使用request.getAttribute()方法接收传递过来的special参数对象
  

  public ModelAndView find(HttpServletRequest request,
            HttpServletResponse response) ...{
        if (log.isDebugEnabled()) ...{
            log.debug("entering 'find' method...");
        }
        int specialId = ServletRequestUtils.getIntParameter(request,
                "specialId", -1);
        Special special = specialManager.findBySpecialId(specialId);
        return new ModelAndView(findView, "special", special);
  }
    <%
      if(null == request.getAttribute("special") )
        ...{
    %>
    <script type="text/javascript">
    alert('<fmt:message key="special.status.conflict"/>');
     location.href='/special/list.html?type=<%=ServletRequestUtils.getIntParameter(request, "type",0)%>
     &p=<%=ServletRequestUtils.getIntParameter(request, "p", 1)%>';
    </script>
     <%     
        return ;
    }%>

5.此时的param是有controller传递过来的参数别名,即spring自带的参数.
   

<form:form commandName="special"  method="post" id="specialForm" name="specialForm"
     onsubmit="return  validateSpecial(this)">
     <input type="hidden" name="type" value="<c:out value="$...{param.type}" />" />
      <input type="hidden" name="p" value="<c:out value="$...{param.p}" />" />
</form:form>

6.通过controller传递参数,得到hashMap所封装的对象.
  

public ModelAndView list(HttpServletRequest req, HttpServletResponse res) ...{
    HashMap<String,Object> videoRelationsMap = new HashMap<String,Object>();
        videoRelationsMap.put("video", video);
       return new ModelAndView(view,"videoRelationsList",videoRelationsMap);
}
<% Videos videos = (Videos)((HashMap)request.getAttribute("videoRelationsList")).get("video");%>
