Chat itself:
<iframe name='chatWindow' id='chatWindow' src ="iframe.php" width="1265" height="400"></iframe> <form action="iframe.php" method="post" id="form" target='chatWindow' > <p>Сообщение:<input name="message" type="text" size="75" maxleght="255"> <input name="submit" type="submit" value="OK"> And this is an iframe:
<script type="text/javascript"> setTimeout("window.location.reload()",15000); // Обновление раз в 15 секунд </script> and
<?php if (isset($_POST['message'])) { $message = $_POST['message']; } $db = mysql_connect("...", "...", "..."); mysql_select_db("...", $db); if (trim($message) != "") { mysql_query("INSERT INTO messages (message) VALUES ('$message')"); } $result = mysql_query("SELECT * FROM messages"); while ($row = mysql_fetch_array($result)) { echo "<br>"; echo "{$row['message']}"; } ?> And the chat script:
<script> jQuery(function ($) { $("#form").onsubmit(function (event) { var message = $("input[name='message']", form).value() if (message) { event.preventDefault(); return false; } return true; }); $("#form input[name='message']").bind('change keydown keypress', function (event) { var text = $(this).value().replace(/^\s+/, "").replace(/\s+$/, ""); $("#form input[type='submit']").prop("disabled", text == ""); }); }); </script>
