您好,我确保我的PHP文件正常工作,但不幸的是我的ajax代码没有。我将ajax放在javascript函数中以在需要时调用该文件,但是当执行该函数时没有任何反应。
这是我的JS代码:
function countdownEnded() {
//make serverscreen dissapear
document.getElementById('serverScreenWrapper').style.display = 'none';
document.getElementById('serverScreenWrapper').style.opacity = '0';
document.getElementById("cashOutNumTwo").style.right = '150%';
document.getElementById("cashOutNumOne").style.right = '150%';
//start Timer
setInterval(gameTimer.update, 1000);
//make player move again
socket.emit('4');
socket.emit('6');
//make game appear
document.getElementById('gameAreaWrapper').style.opacity = 1;
//play sound
document.getElementById('spawn_cell').play();
//cut 5 cents from account - php function
$.ajax({
type: "POST",
url: 'http://cashballz.net/game/5game/subtract5.php',
data: { },
success: function (data) {
alert(data);
}
});
}
我的HTML:
<script src="//code.jquery.com/jquery-2.2.0.min.js"></script>
甚至我的PHP:
<?php
session_start();
$servername = "localhost";
$username = "myName";
$password = "myPass*";
$dbname = "myDBname";
$cash_amount = $_SESSION['cash_amount'];
// Create connection
$userid = $_SESSION['id'];
// You must enter the user's id here. /\
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Fetch the existing value of the cash_amount against that particular user here. You can use the SELECT cash_amount from users where userid = $userid
$_SESSION['cash_amount'] -= 0.05;
$sql = "UPDATE users SET cash_amount = cash_amount - 0.05 WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param('s', $userid);
$result = $stmt->execute();
if($result)
{
echo "5 cents have been subtracted!";
}
else
{
echo mysqli_error($conn);
session_start();
session_unset();
session_destroy();
}
$conn->close();
?>
我不明白为什么我的文件没有被调用。
我有JQuery,我在AJAX上研究了很多,并在这个网站上查看了其他类似的问题。
我去了文件链接,它完美的工作,所以我很确定这是一个JavaScript错误。
我很擅长JS,但是PHP和JQuery的初学者。
感谢你的帮助。
尝试修改您的ajax调用以包含错误处理程序。举个例子:
$.ajax({
type: "POST",
url: 'http://cashballz.net/game/5game/subtract5.php',
data: { },
success: function (data) {
alert(data);
},
error: function(data) {
alert(data);
}
PHP:header('Access-Control-Allow-Origin: *');
允许跨域访问。
