How to implement form submission with AJAX and jQuery?

To implement form submission with AJAX and jQuery, you can follow these steps:

Include the jQuery library in your HTML file by adding the following script tag before your custom JavaScript code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

Create an HTML form that you want to submit using AJAX. For example:

<form id="myForm" action="submit.php" method="POST">
  <input type="text" name="name" placeholder="Name">
  <input type="email" name="email" placeholder="Email">
  <input type="submit" value="Submit">
</form>

Write the jQuery code to handle the form submission event and send the data using AJAX. The jQuery code should be placed within a script tag after including the jQuery library:

<script>
  $(document).ready(function() {
    $('#myForm').submit(function(event) {
      // Prevent the form from submitting normally
      event.preventDefault();
      
      // Serialize form data into an object
      var formData = $(this).serialize();
      
      // Send the form data using AJAX
      $.ajax({
        url: $(this).attr('action'),
        type: $(this).attr('method'),
        data: formData,
        success: function(response) {
          // Handle the success response
          console.log(response);
        },
        error: function(xhr, status, error) {
          // Handle the error response
          console.log(xhr.responseText);
        }
      });
    });
  });
</script>

Update the action attribute of the <form> tag to specify the URL where the form data should be submitted. In the example code, the form data is submitted to submit.php.
In your server-side code (e.g., submit.php), process the form data and send a response back to the AJAX request.
