<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

var S;
S = login.user;
IF (s.value == "")
{Alert ( "username is not empty, registration failed");}
s.focus ();
}
function youxiang ()
{
var S;
var A, B;
A = s.indexOf ( "@");
B s.indexOf = ( ",");
IF (A == B == -1 -1 || A ||> B)
Alert ( "input error");
the else IF (s.indexOf ( "@", A +. 1)! = -. 1)
alert ( "input error");
}
</script>
