jsp 获得checkbox值并写入数据库,可通过以下方法:
1.获得checkbox的值,并传入数组中
2.将数组值转化为字符串
3.写入数据库
例子:
Checkbox.htm
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

- <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
- <title>test</title>
- </head>
- <body>
- <form name="myform" id="myform" method="post" action="CorAdd.jsp">

- </label>
- <input name="" type="button"onclick="document.myform.action='Submit.jsp?menu=add'" />
- </form>
</body> - </html>
提交页面 : Submit.jsp

- String[] CorpMode = request.getParameterValues("CorpMode");
- if(CorpMode.length>0)
- {

- }
- SCorpMode=SCorpMode.substring(0,SCorpMode.length()-1);//去掉SID中的最后一个逗号
- }
- tmp ="insert into Corporation (CorpMode) values('+SCorpMode+');
- if(dbc.executeUpdate(tmp)>=0)
- out.println("<script>alert('信息添加成功！');location.href='CorpAdd.jsp'</script>");
- else
- //out.println("<script>alert('添加失败！');location.href='CorpAdd.jsp'</script>");
- out.print(tmp);
