How can the Ajax call be modified to ensure that the correct method is used for sending data to the server.php file?

To ensure that the correct method is used for sending data to the server.php file in an Ajax call, the type property in the Ajax call should be set to 'POST' if data is being sent through the request body. This is because the default method for Ajax calls is 'GET', which sends data through the URL. By setting the type property to 'POST', the data will be sent securely through the request body.

$.ajax({
    url: 'server.php',
    type: 'POST', // Set the method to POST for sending data through the request body
    data: { key: value }, // Specify the data to be sent to the server
    success: function(response) {
        // Handle the response from the server
    },
    error: function(xhr, status, error) {
        // Handle any errors that occur during the Ajax call
    }
});
