我有一个网站 http://gamepoll.net我希望当我单击“创建投票”时，页面不会刷新。这是 HTML 代码:

JS代码
function SubmitForm(e) {
e.preventDefault();
var game = $("#game").val();
var question = $("#question").val();
var option = $("#option").val();
$.post("submit.php", { game: game, question: question, option: option },
}
submit.php代码
<?php
//Include configuration file
include('includes/config.php');
//Define variables
$question=$_POST['question'];
$game=$_POST['game'];
$option=$_POST['option'];
$choice=$_POST['choice'];
//Generate random number
$rand_value=rand();
//Create temporary folder
mkdir($rand_value);
//Copy page of Ask Poll
copy('page.php', $rand_value . '/page.php');
rename($rand_value . '/page.php', $rand_value . '/index.php');
//Add data into database
mysql_connect($db_host, $db_username, $db_password) or die ("Errore di connessione!");
mysql_select_db($db_name) or die ("Impossibile selezionare database!");
$sql1="CREATE TABLE `" . $rand_value . "` (Question VARCHAR(200), Options VARCHAR(200), Choice INT(11))";
mysql_query($sql1) or die ("Impossibile eseguire la query!");
//Count number of Options available
$count=count($option);
for ($i=0; $i<($count-1); $i++)
{
${$sql . $i}="INSERT INTO `" . $rand_value . "` (Question, Options, Choice) VALUES ('$question', '$option[$i]', '$choice')";
mysql_query(${$sql . $i});
}
?>
一切都很完美，但唯一的问题是，当我单击“创建投票”按钮时，浏览器将我重定向到 Submit.php 空白页面
更新
此代码不起作用
function SubmitForm(e) {
e.preventDefault();
var game = $("#game").val();
var question = $("#question").val();
var option = $("#option").val();
$.post("submit.php", { game: game, question: question, option: option }
return false;
}
你能给我写一个 AJAX 函数吗？就像最后一条评论所说的那样？
最佳答案
将 return false; 放在 SubmitForm 函数的末尾，并在最后一句末尾去掉逗号
function SubmitForm(e) {
e.preventDefault();
var game = $("#game").val();
var question = $("#question").val();
var option = $("#option").val();
$.post("submit.php", { game: game, question: question, option: option }
return false;
}
