这是页面，查询所有出来了，点击修改拿到了ID，但是form里面全是null

package com.wantong.org.filecapturescreen.web.actionform;

import org.apache.struts.action.ActionForm;

public class PictureactionForm extends ActionForm{

-----------------这是actionfrom


public ActionForward updatepictureByName(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
int id=Integer.parseInt(request.getParameter("id"));
PictureactionForm pm=(PictureactionForm)form;
Picture picture=new Picture();
picture.setPictureid(id);
picture.setPname(pm.getPname());
int rseult=PictureFactoryService.getinstrance().updatepictureByName(picture);
if(rseult>0){
return mapping.findForward("deletepic");
}else{
return mapping.findForward("fail");
}

}
----------------------这是ation

[Quote=引用楼主 starbhhc 的回复:]
<a href="picture.do?method=updatepictureByName&id=<bean:write name="pic" property="pictureid"/>">修改</a></span>[/Quote]

你用的是鏈接，不是action，沒有提交過去表單，你要修改，要传过去对应的修改数据，不单单是一个ID，要获取form 就要提交表單！

[lp19890601]

建議： 修改跳到action,有ID，在action里面查处对象的数据，转跳另一個頁面赋值（发到文本框里）再提交表单修改

[starbhhc]

那我可不可是调用一个方法：
function show（）
｛
document.form.action="";
document.form.submit();
｝
