I want to build a web with HTML, CSS, Javascript, PHP and MySQL. I want my web will have a feature that the customers want to download the file from the web, if they don't want to download faster, no need to go through the shorten link, they will enter the code and web will use PHP and MySQL to check if the code is in the database. If the code valid, they will press the Next button to go to download file.
This is all my code:

document.getElementById('nextbtn').onclick = function() {

};

Please help me!
This function will be invoked immediately. IIFE
(function(){
document.getElementById('nextbtn').disabled = false;
document.getElementById('nextbtn').onclick = function() {
window.open('https://www.youtube.com');
})()
Is removing the setTimeout only not enough?
<script>
(function(){
document.getElementById('nextbtn').disabled = false;
document.getElementById('nextbtn').onclick = function() {
window.open('https://www.youtube.com');
})();
</script>
<script>
document.getElementById('nextbtn').disabled = false;
document.getElementById('nextbtn').onclick = function() {

You can store the last message id which you played sound for, and at every refresh action, you can check if the last message id is equals to id you stored before. If not, you play sound.
To be more clear:
$lastMessageId=5;
$lastMessageIdWePlayedSoundFor=4;
if($lastMessageId!=$lastMessageIdWePlayedSoundFor)
{
////play sound here
$lastMessageIdWePlayedSoundFor=$lastMessageId;
}
So whenever there is a new message we haven't played a sound for it's existance, we play sound. You can use this algorithm.
Good day all, I'm working on a jquery game and I'm making a welcome screen. I'm using ajax to switch pages. So far the pages are switching exactly but the page index.php where game's elements are running has stopped working and no animation is working. Here are the codes:
welcome.php script:
<head>
<script src="js/jquery-1.9.1.min.js"></script>
<script>
function swapContent(cv) {
var url = "page-switch.php";
$.post(url, {contentVar: cv} ,function(data) {
$("#myDiv").html(data).show();
});
}
</script>
</head>
<body>
Play!
Scoreboard
<div id="myDiv"></div>
</body>
page-switch.php script:
<?php
$contentVar = $_POST['contentVar'];
if ($contentVar == "con1") {
header('Location: index.php');
} else if ($contentVar == "con2") {
header('Location: score-post.php');
}
?>
index.php script:
<head>
<title>Space Game Test 01</title>
<script src="js/jquery-1.9.1.min.js"></script>
<script src="js/jquery-collision.js"></script>
<script src="js/core-animation.js"></script>
<link rel="stylesheet" href="css/jquery-ui.css">
<link rel="stylesheet" href="css/content-style.css">
</head>
<body onload="start()">
<div id="content">
<div id="galaxy"><img src="images/galaxy.png" /><img src="images/galaxy.png" /></div>
</div>
<div id="linkpanel"></div>
<div id="scoreboard">Score<br><div id="score">0</div><input type="button" id="pause" value="Pause" /><br>
<input type="button" id="resume" value="Resume" /></div>
<script>
var pause = null;
$("#resume").click(function () {
if(!pause)
{
pause = setInterval(scroll_ns, 50)
}
});
$("#pause").click(function () {
clearInterval(pause);
pause = null;
});
</script>
</body>
Am I doing wrong here? I'm pretty noob in ajax but I really need to learn. Please help! Tnx.
you can use load function also
<script>
function swapContent(page) {
jQuery( "#myDiv" ).load(page);
}
</script>
Play!
Scoreboard
<div id="myDiv"></div>
You may try something like this you have to redirect to the page after getting response from ajax.
<script>
function swapContent(cv) {
var url = "page-switch.php";
$.post(url, {contentVar: cv} ,function(data) {
//alert(data)
if(data="first"){
window.location.href = "index.php";
}
if(data="second"){
window.location.href = "score.php";
}
});
}
</script>
</head>
<body>
Play!
Scoreboard
<div id="myDiv"></div>
</body>
page-switch.php script:
<?php
$contentVar = $_POST['contentVar'];
if ($contentVar == "con1") {
echo "first";
} else if ($contentVar == "con2") {
echo "second";
}
?>
I'm doing a small project where I'm trying to create a continual gallery for a user; whereby, they upload a file, and it immediately appears on the same page. The one thing I can't manage to accomplish is to keep the files there on the page even if the page is refreshed. In other words, I want the user to return and see all of their uploaded files as if they never left, until they close the browser. I've tried using cookies and session variables but I'm confused on how to implement this. Here is my Code. I APOLOGIZE IN ADVANCE FOR BAD INDENTATION.
My index.php:
<?php
// Process image
$uploadName = 'uploaded/pic.jpg';
if (count($_FILES))
move_uploaded_file($_FILES['image']['tmp_name'], $uploadName);
?>
<!DOCTYPE html>
<html>
<head>
<style>
li { display: inline-block; padding: 200px; width: 200px;}
img { width: 100%; height:100%;}
</style>
<script type="text/javascript">
function iframeSubmit(formElem, action, callback) {
// name a callback that will be called from inside the iframe
var callbackName = 'iframe' + Math.ceil(Math.random() * 10000);
action = action + (action.indexOf('?') == -1 ? '?' : '&') + 'callback='+
callbackName;
// create an iframe and use the callback as its name
var iframe = document.createElement('iframe');
iframe.setAttribute('name', callbackName);
iframe.style.display = 'none';
// add the target and edit the action of the form
formElem.setAttribute('target', callbackName);
formElem.setAttribute('action', action);
// add the hidden iframe after the form
formElem.parentNode.appendChild(iframe);
window[callbackName] = callback;
}
;
</script>
