網頁登錄界面設計代碼_網頁製作中登陸界面設計代碼

1、javascript html 設計一個登錄界面

注冊頁面代碼：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>注冊</title>
</head>
<body>

<form method="post" onsubmit="return false" id="form">
    <input type="text" name="username" placeholder="用戶名"><br>
    <input type="password" name="password" placeholder="密碼"><br>
    <input type="password" name="rePassword" placeholder="再次輸入密碼"><br>
    <input type="submit" onclick="register_user()" value="注冊"><br>
</form>
<a href="login.html">去登錄</a><script>
    var localDB = openDatabase('localDB', '1.0', 'Test DB', 2 * 1024 * 1024);
    localDB.transaction(function (ts) {
        ts.executeSql('CREATE TABLE IF NOT EXISTS user(username,password)')
    });
    function register_user() {
        var username = document.getElementsByTagName("input")[0].value;
        var password = document.getElementsByTagName("input")[1].value;
        var rePassword = document.getElementsByTagName("input")[2].value;
        if(password != rePassword)
        {
            alert("兩次輸入的密碼不同，請重新輸入");
        }else
{
            localDB.transaction(function(ts){
                ts.executeSql("INSERT INTO user (username,password) VALUES ('"+username+"','"+password+"');");
                alert("注冊成功");
            });
        }
    }
</script>
</body>
</html>

登錄頁面代碼：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登錄</title>
</head>
<body>
<form onsubmit="return false" method="post">
    <input type="text" placeholder="用戶名"><br>
    <input type="password" placeholder="密碼"><br>
    <input type="submit" value="登錄" onclick="login()"><br>
</form>
<a href="register.html">去注冊</a>
<script>
    var localDB = openDatabase('localDB', '1.0', 'Test DB', 2 * 1024 * 1024);
    localDB.transaction(function (ts) {
        ts.executeSql("SELECT * FROM user",[],function (tx, results) {
            var len = results.rows.length;
            if(len<=0)
            {
                localDB.transaction(function (ts) {
                    ts.executeSql('CREATE TABLE IF NOT EXISTS user(username,password)')
                });
            }
        });
    });

    function login() {
        var username = document.getElementsByTagName("input")[0].value;
        var password = document.getElementsByTagName("input")[1].value;
        localDB.transaction(function (ts) {
            ts.executeSql("SELECT * FROM user WHERE username='"+username+"';",[],function (ts, res) {
                if(res.rows.length<=0)
                {
                    alert("登錄失敗，用戶未注冊");
                }else if (password == res.rows[0].password)
                {
                    alert("登錄成功,三秒後跳轉到百度");
                    setInterval(function () {
                        location.href = "https://www.baidu.com";
                    },3000);
                }else
{
                    alert("登錄失敗，密碼錯誤");
                }
            });
        })
    }
</script>
</body>
</html>

以上代碼使用了WEB SQL，還請選擇合適的瀏覽器查看。

2、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();">
<table width="300" border="0" align="center" cellpadding="5" cellspacing="0" class="border" >
<tr class="title">
<td colspan="2" align="center"> <strong>管理員登錄</strong></td>
</tr>

<tr>
<td height="120" colspan="2" class="tdbg">
<table width="250" border="0" cellspacing="8" cellpadding="0" align="center">

<td align="right">用戶名稱：</td>
<td><input name="UserName" type="text" id="UserName2" size="23" maxlength="20"></td>

</tr>
</table>

</tr>
</table>
<p align="center">後台管理頁面需要屏幕解析度為 <font color="#FF0000"><strong>1024*768</strong></font>
或以上才能達到最佳瀏覽效果！<br>
需要瀏覽器為<strong><font color="#FF0000"> </font></strong><font color="#FF0000"><strong>IE5.5</strong></font>
或以上版本才能正常運行！！！</p>

</html>

3、HTML網頁設計：一個簡單的登錄界面可以連接到資料庫記錄的代碼

如下參考：

1.首先，在您的計算機桌面上創建一個新文件夾，然後在該文件夾中創建一個新的文本文檔。

2.然後用記事本雙擊打開文本文檔，如下圖所示，然後編寫一個簡單的HTML代碼。

3.點擊「另存為」功能選項，顯示默認的「另存為」代碼為ANSI。

4.我們將把編碼和文件名更改回圖中所示的圖像並保存它。

5.然後回到新創建的文件夾，找到一個額外的HTML文件。

6.最後，使用瀏覽器打開HTML文件。結果如圖所示。

4、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>

5、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();
}

}
