这段代码看起来已经很不错了,但是还是可以进行一些优化:
1. 考虑使用 HTTPS 协议来保证传输数据的安全性。
2. 使用 HTML5 标签替换旧的标签,例如将 <input type="button"> 替换为 <button> 标签。
3. 将 CSS 样式放到单独的文件中,以便维护和管理。
4. 对于验证用户名和密码的逻辑,可以将其放到后端服务器中进行处理,避免密码泄露的风险。

$.ajax({

error: function() {
alert("Error occurred.");

这个优化后的界面代码做了以下改进:
1. 使用 CSS 来美化界面,让它更加美观、易于使用和可读性更高。
2. 将表单元素布局在一个垂直方向上,使界面更加整洁。
3. 对表单元素的大小、间距和样式进行微调,使它们更加一致和易于使用。
4. 将 JavaScript 代码移到一个单独的 <script> 标签中,使它更加易于维护和重用。
给这段代码配一个bootstrap 风格的css 样式。 <!DOCTYPE html> <html> <head> <title>用户登录</title> <link rel="stylesheet" type="text/css" href="login.css"> </head> <body> <h1>用户登录</h1> <form action="登录.HTML" method="post"> <label style="display: inline-block;" for="username">用户名:</label> <input style="display: inline;"type="text" id="username" name="username"><br><br> <label style="display: inline-block;" for="password">密 码:</label> <input style="display: inline;"type="password" id="password" name="password"><br><br> <label style="display: inline-block;" for="remember">记住我:</label> <input style="display: inline;"type="checkbox" id="remember" name="remember"><br><br> <input type="submit" value="登录"> </form> </body> </html>
