是的，有可能做到这一点。这是您的示例，但采用PHP方式。您可以使用此引用转换为JSP。
HTML
<input type="text" id="hey">
jQuery的
$('#hey').on('keyup', function(){ $.ajax({ type : 'POST', url : 'insertData.php', // --> server side pre to insert data into db data: { val : $(this).val() }, success : function(msg){ // msg -> return by server side // any pre in success // if success will print out this 'New record created successfully' // if error will print out this 'Error occured' console.log(msg); } });});PHP-insertData.php
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); $sql = "INSERT INTO comment (myText) VALUES (".$_POST['val'].")"; if ($conn->query($sql) === TRUE) { echo "New record created successfully"; } else { echo "Error occured"; } $conn->close(); ?>
