验证函数不能用VBSCRIPT写,要用JAVASCRIPT写,
然后再调用.
举个例子
<script language="javascript">
function check()
{
if (!checkspace(document.reg.userName.value))
{if(document.reg.userName.value.length<4)
{ alert("用户名长度不能小于4");
document.reg.userName.focus();
return false;
}}
else
{ alert("用户名不能全是空格");
document.reg.userName.focus();
return false;
}
if(document.reg.userPwd.value.length<6)
{ alert("密码长度不能小于6");
document.reg.userPwd.focus();
return false;
}
if(document.reg.userPwd.value!=document.reg.confirmPwd.value)
{
alert("两次密码输入不一致");
document.reg.userPwd.focus();
return false;
}
var email=/^[_a-z0-9]+@([_a-z0-9]+\.)+[a-z0-9]{2,3}$/;
if (!email.test(document.reg.email.value))
{ alert("电子邮件格式不正确");
document.reg.email.focus();
return false;
}
}
</script>
