1.今天学习了用户注册界面
Login.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>登陆界面Login</title>
<script>
function submit()
{
var s;
s=login.user;
if(s.value=="")
{alert("用户名是不能为空,注册失败");}
s.focus();
}
function check(t)
{
var p1,p2;
p1=login.paw.value;
p2=login.paww.value;
if(p1!=p2)
{alert("两次密码不一致,请确认密码");}
}
function checkcode()
{
var s;
s=1000+Math.floor(Math.random()*9000);
return s;
}
var num;
function scanfin()
{
var s;
s=document.getElementById("k");
if(parseInt(s.value)!=num)
alert("验证码输入错误,请重新输入!");
}
function product()
{
s=1000+Math.floor(Math.random()*9000);
num=s;
var v=document.getElementById("code");
v.innerHTML=num;
}
</script>
