如何解决JQuery Ajax表单提交保持静态，我不明白为什么！
| 可能更容易看一下这个小提琴：http://jsfiddle.net/pkAGz/，process.PHP
<?PHP
//Retrieve form data.
//GET - user submitted data using AJAX
//POST - in case user does not support javascript,we\'ll use POST instead
$name = ($_GET[\'name\']) ? $_GET[\'name\'] : $_POST[\'name\'];
$email = ($_GET[\'email\']) ?$_GET[\'email\'] : $_POST[\'email\'];
//flag to indicate which method it uses. If POST set it to 1
if ($_POST) $post=1;
//Simple server side validation for POST data,of course,//you should validate the email
if (!$name) $errors[count($errors)] = \'Please enter a name.\';
//if the errors array is empty,send the mail
if (!$errors) {
$name = $name[array_rand($name)];
$to = \'$name <$name email adress if set>\';
//sender
$from = $name . \' <\' . $email . \'>\';
//subject and the html message
$subject = \'Comment from \' . $name;
$message = \'
<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\"
\"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
<html xmlns=\"http://www.w3.org/1999/xhtml\">
<head></head>
<body>
<table>
<tr><td>Name</td><td>\' . $name . \'</td></tr>
<tr><td>Email</td><td>\' . $email . \'</td></tr>
</table>
</body>
</html>\';
//send the mail
$result = sendmail($to,$subject,$message,$from);
//echo \"\\n\\n$name has been nominated to make the tea!\\n\\n\";
//echo \"\\n\\nThey will also be notified by e-mail if you entered their address.\\n\\n\";
//if POST was used,display the message straight away
if ($_POST) {
if ($result) echo \"\\n\\n$name has been nominated to make the tea!\\n\\nThey will also be notified by e-mail if you entered their address.\\n\\n\";
else echo \'Sorry,unexpected error. Please try again later\';
//else if GET was used,return the boolean value so that
//ajax script can react accordingly
//1 means success,0 means Failed
} else {
echo $result;
}
//if the errors array has values
} else {
//display the errors message
for ($i=0; $i<count($errors); $i++) echo $errors[$i] . \'<br/>\';
echo \'<a href=\"index.PHP\">Back</a>\';
exit;
}
//Simple mail function with HTML header
function sendmail($to,$from) {
$headers = \"MIME-Version: 1.0\" . \"\\r\\n\";
$headers .= \"Content-type:text/html;charset=iso-8859-1\" . \"\\r\\n\";
$headers .= \'From: \' . $from . \"\\r\\n\";
$result = mail($to,$headers);
if ($result) return 1;
else return 0;
}
?>
解决方法
将Firebug用于Firefox，或在Chrome / Safari中查看控制台。因此，您会发现自己遇到了JavaScript错误：
Uncaught ReferenceError: comment is not defined
//cancel the submit button default behaviours
return false;
