Anda menggunakan perpustakaan JQuery, tetapi anda menggunakan arahan JavaScript asli untuk mengendalikan butang dan menyerahkan(). Sama ada anda menggunakan semua JS Tulen, atau anda menggunakan semua JQuery.
Kod di bawah hanya menggunakan JQuery. Selain itu, saya menggantikan hantar dengan butang.
.
Akhirnya, butang tidak DIPOS, jadi jika anda perlu menguji, lakukannya pada medan input.
Di bawah ialah kod dengan elemen yang saya nyatakan yang sepatutnya membantu anda.
<? // 当表单提交时处理表单数据 if ($_SERVER["REQUEST_METHOD"] == "POST") { if(isset($_POST['username'])) { $uname=$_POST['username']; header('Location: success.php'); } } ?> <!DOCTYPE html> <html> <head> <title>My Form</title> </head> <body> <form id="your_form_id" action="test4.php" method="post"> <p><label>Username</label> <input id="username" type="text" name="username" value="" autofocus/></p> <input type="button" id="submit-button" name="submit-button" value="Login" /> </form> <script src="http://code.jquery.com/jquery-1.11.3.min.js"></script> <script type="text/javascript"> $("#submit-button").on("click", function(e){ $('#submit-button').prop('disabled',true); $('#submit-button').val('Processing, please wait...'); $('#your_form_id').submit(); }); </script> </body> </html>

Untuk mencapai ini, prinsip berikut boleh digunakan:
test-a.php:
<!DOCTYPE html> <html> <head> <title>Ajax example with Page loader</title> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> <style> /*CSS for Page loader*/ #loader { display: none; position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%); z-index: 9999; } </style> <script> $(document).ready(function() { $('#myForm').submit(function(e) { e.preventDefault(); // 阻止元素的默认操作 $('#submitButton').prop('disabled', true); // 禁用id为submitButton的按钮 $('#loader').show(); // 显示“页面加载器” // 发送AJAX请求 $.ajax({ url: 'test-b.php', //处理PHP文件的路径 type: 'POST', data: $(this).serialize(), success: function(response) { // 将响应保存到会话变量中 sessionStorage.setItem('response', response); // 转到“test-c.php” window.location.href = 'test-c.php'; } }); }); }); </script> </head> <body> <form id="myForm" method="POST"> <label for="name">Name:</label> <input type="text" name="name" id="name" required><br> <label for="email">Email:</label> <input type="email" name="email" id="email" required><br> <input type="submit" id="submitButton" value="Submit"> </form> <div id="loader"> This is page loader, please wait... </div> </body> </html>
ujian-b.php:
<?php session_start(); $name = $_POST['name']; $email = $_POST['email']; // 在这里可以使用$name和$email进行进一步处理或保存到数据库 // 打印响应数据的示例 $response = "The following data has been received:<br>"; $response .= "Name: " . $name . "<br>"; $response .= "Email: " . $email . "<br>"; // 将响应保存到会话变量中 $_SESSION['response'] = $response; // 完成本文件的工作 exit; ?>
test-c.php:
<!DOCTYPE html> <html> <head> <title>Success</title> <style> h1 { color: green; } </style> </head> <body> <h1>Process file response:</h1> <?php session_start(); if (isset($_SESSION['response'])) { $response = $_SESSION['response']; echo $response; unset($_SESSION['response']); // 取消设置会话变量 } else { echo "No data to show."; } ?> </body> </html>
