1.最简单的action页面提交和参数p的传递
<
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
"
οnclick=
"
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
"
);
%>
