Question

我有一个网站http://gamepoll.net，我希望当我点击创建投票时，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});
    }   
?>

一切正常但唯一的问题是当我点击创建投票按钮时，浏览器会将我重定向到submit.php空白页

更新

此代码无效

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;
}

你能写一个AJAX函数，就像最后一条评论所说的那样吗？

Answer 1

将return false;放在SubmitForm函数的末尾，并在最后一句末尾删除逗号

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;
}

Answer 2

将return false;放在SubmitForm函数的末尾，或将onclick="SubmitForm();"更改为onclick="SubmitForm(); return false;"

Answer 3

你可以添加onsubmit =“return false;”你的表格：

<form onsubmit="return false;">
*****
****
</form>

Answer 4

如果您希望页面不刷新，请单击“创建投票”按钮使用Ajax功能。它加载页面的一部分而不刷新整个页面。

提交后不要刷新页面
