<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<script language="javascript" src="form.js" src="form.js"></script>
</head>
<body>
<form action="post.php" method="get" name="form1" onsubmit="return form_sub()">
<table width="271" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td width="85"><div align="right">姓名：</div></td>
<td width="186"><input name="username" type="text" id="username"></td>
</tr>
<tr>
<td><div align="right">密码：</div></td>
<td><input name="password" type="password" id="password"></td>

</table>
<p align="center">

代码如下:
function form_sub()
{
if(!test_username(document.form1.username.value))
{
alert("姓名格式不正确");
return false;
}
if(!test_date(document.form1.birthday.value))
{
alert("日期格式不正确");
return false;
}
if(!test_email(document.form1.email.value))
{
alert("E-mail地址格式不正确");
return false;
}
if(!test_password(document.form1.password.value, document.form1.password2.value))
{
alert("两次密码输入不相同");
return false;
}
}
function test_username(str_username)
{
var pattern = /[a-zA-Z_]/;
if(pattern.test(str_username))
return true;
else
return false;
}
function test_date(str_birthday)
{
var pattern = /[0-9]{4}-[0-9]{2}-[0-9]{2}/;
if(pattern.test(str_birthday))
return true;
else
return false;
}
function test_email(str_email)
{
var pattern = /^[a-zA-Z0-9_.]+@([a-zA-Z0-9_]+.)+[a-zA-Z]{2,3}$/;
