JSP表单提交与接收
在Myeclipse中新建web project,在webroot中新建userRegist1.jsp,代码如下
<%@ page contentType="text/html;charset=gb2312"%> <script language="javascript"> function on_submit(){//验证数据的合法性 if (form1.username.value == ""){ alert("用户名不能为空,请输入用户名!"); form1.username.focus(); return false; } if (form1.userpassword.value == ""){ alert("用户密码不能为空,请输入密码!"); form1.userpassword.focus(); return false; } if (form1.reuserpassword.value == ""){ alert("用户确认密码不能为空,请输入密码!"); form1.reuserpassword.focus(); return false; } if (form1.userpassword.value != form1.reuserpassword.value){ alert("密码与确认密码不同"); form1.userpassword.focus(); return false; } if (form1.email.value.length!= 0){ for (i=0; i<form1.email.value.length; i++) if (form1.email.value.charAt(i)=="@") break; if (i==form1.email.value.length){ alert("非法E-mail地址!"); form1.email.focus(); return false; } }else{ alert("请输入E-mail!"); form1.email.focus(); return false; } } </script> <html> <head> <title>新用户注册</title> </head> <body> <form method="POST" action="acceptUserRegist1.jsp" name="form1" onsubmit="return on_submit()"> 新用户注册<br> 用户名(*):<input type="text" name="username" size="20"><br> 密 码(*):<input type="password" name="userpassword" size= "20"><br> 再输一次密码(*):<input type="password" name="reuserpassword" size= "20"><br> 性别:<input type="radio" value="男" checked name="sex">男<input type="radio" name="sex" value="女">女<br> 出生年月:<input name="year" size="4" maxlength=4>年 <select name="month"> <option value="1" selected>1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="8">7</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> </select>月 <input name="day" size="3" maxlength=4>日<br> 电子邮箱(*):<input name="E-mail" maxlength=28><br> 家庭住址:<input type="text" name="address" size="20"><br> <input type="submit" value="提交" name="B1"><input type="reset" value="全部重写" name="B2"><br> </form> </body> </html>
(代码中javascript解决逻辑判断问题,保证输入格式的正确性)
在浏览器输入地址,运行,然后输入相关参数:
然后在webroot中新建acceptUserRegist1.jsp,用于接收相关内容,代码如下:
<%@ page contentType="text/html;charset=gb2312"%> <%! public String codeToString(String str){//处理中文字符串的函数 String s=str; try{ byte tempB[]=s.getBytes("ISO-8859-1"); s=new String(tempB); return s; }catch(Exception e){ return s; } } %> <html> <head> <title>接收新用户注册</title> </head> <body> 这是新用户注册所提交的数据: <br> 用户名是:<%=codeToString(request.getParameter("username"))%><br> 密码是:<%=codeToString(request.getParameter("userpassword"))%><br> 性别是:<%=codeToString(request.getParameter("sex"))%><br> 出生年月是: <%=request.getParameter("year")+request.getParameter("month")+request. getParameter("day")%><br> 电子邮箱是:<%=request.getParameter("E-mail")%><br> 家庭住址是:<%=codeToString(request.getParameter("address"))%><br> </body> </html>
运行结果如下:
