Then you should have a look at ajax:

http://api.jquery.com/jquery.ajax/

$("#mysubmitbutton").click(function() {
    $.ajax({
        url: "mywebsite.com/save-comment.php",
        type: "post",
        data: {commentText: $("#comment").val()},
        success: function(text) {
            if(text == "true") {
                alert("It worked! Your data were saved hurrayyy!");
            }
        },
        error: function() {
            alert("Print some error here!");
        }
   });        
});

On serverside accept your data:

$myText = $_POST["commentText"];
$query = "UPDATE comment SET text = '" . mysql_real_escape_string($myText) . "'";
if(mysql_query($query) == true) {
    echo "true";
} else {
    echo "false";
}
die();
