如何在表单提交中使用jquery ajax

Changed the code to this now. Form is located in subscribe.php which in included into the index page.

<form class="subscribe" id="email" method="get">
    <input class="email" id="emailaddress" name="email" type="text" placeholder="EXAMPLE@EMAIL.COM" required>
    <input class="button" type="submit" id="emailSub" value="Subscribe">
</form>
<div id="subResult"></div>

Jquery is at bottom of the index page

$(document).ready(function() {
    $('#emailSub').click(function() {
        var email = $('#emailaddress').val();
        alert(email);
        $.ajax({
            type: "GET",
            dataType: 'script', //<-Data Type for AJAX Requests(xml | html | script | json)
            url: 'checksub.php',
            data: {
                'e': email
            },
            success: function(result) {
                $("#subResult").html(result);
            }
        });
    })
});

Checksub page is this now for testing.

<?php include 'admin/includes/db_connection.php'; ?>
<?php 
$email = mysqli_real_escape_string($db, $_GET['e']);
echo "test string:";
echo $email;
?>

    maybe you should to change dataType? try it:

    $.ajax({
        type: "GET",
        dataType: 'html', //<-Data Type for AJAX Requests(xml | html | script | json)
        url: 'checkemail.php',
        data: {
            'e': email
        },
        success: function(data) {
            $("#subResult").html(result);
        }
    });
    

    and

    <input class="button" type="submit" id="emailSub" value="Subscribe">
                                  ^ HERE
    

    should be :

    <input class="button" type="button" id="emailSub" value="Subscribe">
    

    because of submit is submiting form and refreshing the page.. so jquery not work..

    Specifying the Data Type for AJAX Requests
