再冲刺
在完成上一次的冲刺后，这次，我们组根据本学期新学习的javaweb语言编写了我们的登录界面。
编写的登录界面代码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登陆首页</title>
</head>
<body>
<form name="form1" action="check.jsp" method="post">
用户名:<input name="name" type="text" />
<p>
密 码:<input name="pwd" type="password" />
<p>
验证码:<input name="yanzheng" type="text" size="8"/>
<%
int intmethod=(int) ((((Math.random())*11))-1);
int intmethod2=(int) ((((Math.random())*11))-1);
int intmethod3=(int) ((((Math.random())*11))-1);
int intmethod4=(int) ((((Math.random())*11))-1);
String intsum=intmethod+""+intmethod2+intmethod3+intmethod4;
%>
<input type="hidden" name="vcode" value="<%=intsum %>">

<input name="submit" type="submit" value="登陆" onClick="return mycheck()">
<input name="submit1" type="reset" value="重置">
</form>
<script type="text/javascript">
function mycheck(){
if(form1.name.value=="")
{
alert("请输入用户名！");
form1.name.focus();
return false;
}
if(form1.pwd.value=="")
{
alert("请输入密码！");
form1.pwd.focus();
return false;
}
if(form1.yanzheng.value=="")
{
alert("请输入验证码！");
form1.yanzheng.focus();
return false;
}
if(form1.yanzheng.value!=form1.vcode.value)
{
alert("请输入正确的验证码！");
form1.yanzheng.focus();
return false;
}
form1.submit();
}
</script>
</body>
</html>

以上就是登录界面所有代码，现在还不是太完善，等到了后期，我们会将我们的界面进行美化与完善。
