JSP 第一天：提交表单--获取表单中的数据值
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
主要用到两个内置的对象：out 和 request
out：用来在小脚本里面输出显示内容
request：用来获取用户提交的信息（包括：用户的IP，表单中的内容等）
[java] view plaincopyprint?
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <form action="getInfo.jsp" name="myform" method="post"> <table> <tr> <td>姓名：</td> <td><input type ="text" name="txtname" /></td> </tr> <tr> <td>密码：</td> <td><input type ="password" name="txtpwd" /></td> </tr> <tr> <td>男<input type="radio" name="sex" value="male" /></td> <td>女<input type="radio" name="sex" value="female" /></td> </tr> <tr> <td colspan="4"> 籃球<input type="checkbox" name="hobby" value="籃球" /> 排球<input type="checkbox" name="hobby" value="排球" /> 足球<input type="checkbox" name="hobby" value="足球" /> 乒乓球<input type="checkbox" name="hobby" value = "乒乓球"/> </td> </tr> <tr> <td colspan="2"> <input type="submit" name="submit" value="提交" /> <input type="reset" name="reset" value="重置" /> </td> </tr> </table> </form> </body> </html>
