3. 網頁登錄源代碼

4. html網頁設計：一個簡單的登錄界面代碼！

大致形式應該是這樣的：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>3</title>
</head>
<body>
<div align="center">
<form action="" name="myform">
<table>
<tr>
<td>用戶名：</td>
<td><input type="text" id="user" /></td>
</tr>
<tr>
<td>密碼：</td>
<td><input type="text" id="password" /></td>
</tr>
<tr>
<td>驗證碼：</td>
<td align="left"><input type="text" size="5" id="code" /></td>
</tr>
</table>
</form>
<table>
<tr>
<td>
<input type="submit" value="提交" onclick=myfun_submit() />
</td>
<td>
<input type="submit" value="重置" onclick=myfun_reset() />
</td>
</tr>
</table>
</div>
<script type="text/javascript">
function myfun_submit(){

var user_val = document.getElementById("user").value;
var password_val = document.getElementById("password").value;
if(user_val==""){

alert("用戶名不能為空！！");

}else if(password_val==""){

alert("密碼不能為空！！！");

}

}
function myfun_reset(){
document.getElementById("user").value = "";
document.getElementById("password").value = "";
document.getElementById("code").value = "";

}
</script>
</body>
</html>

5. 怎麼製作一個登陸界面的網頁代碼

if(a==111 && b==123)
{
alert("登錄成功！");
disp=open("http://www.hao123.com","result");
return false;
}

alert語句後面句改成 location.href='你希望跳轉到的頁面地址';

6. 用html代碼編寫一個簡單的登陸界面

<!DOCTYPE html><html lang="zh-CN"><head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>登錄</title>
<link href="css/bootstrap.min.css" rel="stylesheet"></head><body><nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="./">jsp作業</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li><a href="login.html">登錄</a></li>
</ul>
</div>
</div></nav><div class="container">
<div class="row">
<div class="col-md-4">

</div>
<div class="col-md-4">
<form class="form-signin" target="submitFrame" method="post">
<h2 class="form-signin-heading">登錄到jsp作業</h2>
<label for="inputEmail">Email</label>
<input type="email" id="inputEmail" class="form-control" placeholder="請輸入Email" required autofocus><br>
<label for="inputPassword">密碼</label>
<input type="password" id="inputPassword" class="form-control" placeholder="請輸入密碼" required>
<div class="checkbox">
<label>
<input type="checkbox" value="remember-me" checked="checked"> 記住密碼 </label>
</div>
<button type="submit" class="btn btn-primary" id="btn-login">登錄</button>
<a href="reg.html" class="btn btn-default">注冊</a>
</form>
<iframe style="display: none;" name="submitFrame" src="about:blank"></iframe>
</div>
<div class="col-md-4">
</div>
</div>
<script src="js/jquery.min.js"></script></body></html>

7. asp登錄界面源代碼

要是你要的話。我可以發一個文件給你。裡面的內容是一本書的所有例子。包括有
「留言板、注冊和登陸、Blog、小型論壇、新聞發布等等。」
都是ASP版的。只要你建好站點。復制相應的文件到你站點下就行了。

8. 網頁製作中登陸界面設計代碼

<%@language=vbscript codepage=936 %>
<%
option explicit
'強制瀏覽器重新訪問伺服器下載頁面，而不是從緩存讀取頁面
Response.Buffer = True
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.Expires = 0
Response.CacheControl = "no-cache"
'主要是使隨機出現的圖片數字隨機
%>
<html>
<head>
<title>管理員登錄</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<link rel="stylesheet" href="Admin_Style.css">
<script language=javascript>
function SetFocus()
{
if (document.Login.UserName.value=="")
document.Login.UserName.focus();
else
document.Login.UserName.select();
}
function CheckForm()
{
if(document.Login.UserName.value=="")
{
alert("請輸入用戶名！");
document.Login.UserName.focus();
return false;
}
if(document.Login.Password.value == "")
{
alert("請輸入密碼！");
document.Login.Password.focus();
return false;
}
//if (document.Login.CheckCode.value==""){
// alert ("請輸入您的驗證碼！");
// document.Login.CheckCode.focus();
// return(false);
}
}
</script>
</head>
<body onLoad="SetFocus();">
<p> </p>
<form name="Login" action="Admin_ChkLogin.asp" method="post" target="_parent" onSubmit="return CheckForm();">

9. JAVA 中 GUI登錄界面設計源代碼

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class Login {

private JFrame frame = new JFrame("登錄");
private Container c = frame.getContentPane();
private JTextField username = new JTextField();
private JPasswordField password = new JPasswordField();
private JButton ok = new JButton("確定");
private JButton cancel = new JButton("取消");
public Login(){
frame.setSize(300,200);
c.setLayout(new BorderLayout());
initFrame();
frame.setVisible(true);
}

private void initFrame() {

//頂部
JPanel titlePanel = new JPanel();
titlePanel.setLayout(new FlowLayout());
titlePanel.add(new JLabel("系統管理員登錄"));
c.add(titlePanel,"North");

//中部表單
JPanel fieldPanel = new JPanel();
fieldPanel.setLayout(null);
JLabel l1 = new JLabel("用戶名:");
l1.setBounds(50, 20, 50, 20);
JLabel l2 = new JLabel("密碼:");
l2.setBounds(50, 60, 50, 20);
fieldPanel.add(l1);
fieldPanel.add(l2);
username.setBounds(110,20,120,20);
password.setBounds(110,60,120,20);
fieldPanel.add(username);
fieldPanel.add(password);
c.add(fieldPanel,"Center");

//底部按鈕
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new FlowLayout());
buttonPanel.add(ok);
buttonPanel.add(cancel);
c.add(buttonPanel,"South");
}

public static void main(String[] args){
new Login();
