I am trying to display youtube audio without video with the below code so I am changing the video id but it is playing the same id again and again.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>About</title>
<script type="text/javascript">
function val1(val)
{
document.getElementsByTagName("div")[0].setAttribute("data-video", val);
alert(val);
}
</script>
</head>
<body onload="val1('WKV_z36pVAk')">
<h3 style="color:#0066dd">Hello</h3>
<center>
<div data-video="8IYzyTYucKQ"
data-autoplay="0"
data-loop="1"
id="youtube-audio">
</div>
</center>
<button>change</button>
</body>
<script src="https://www.youtube.com/iframe_api"></script>

Not quite sure what you are trying to create, but this might head you into the right direction.
You can reload the specific element in a kind of hacky way using this code
function reload(vidId){ <-- Added a parameter
var container = document.getElementById("youtube-audio");
container.setAttribute("data-video", vidId); <-- Added line to change data-video
var content = container.innerHTML;
container.innerHTML= content;
}
And then add this to your HTML
<button onclick="reload('8IYzyTYucKQ')">Reload</button> <-- Added the parameter to what the `data-video` should be changed

I'm a super novice to javascript, and maybe this has been answered elsewhere but I can't find it because I'm still learning the terminology.
I'm trying to use the content of a div tag to define the css values of a div it is nested within.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function data(){
alert();
var sizeOverride = document.getElementById('newdata').innerHTML
alert(sizeOverride)
}
</script>
</head>
<body>
<div id=sizeChange>
<div id="newdata">
40 <!--The idea is for this to be 40px-->
</div>
</div>
<script type="text/javascript">
document.getElementById("sizeChange").style.fontSize = "sizeOverride" + "px";
</script>
</body>
</html>
Eventually the plan is to use this to define the location and label of a bar on a graph, i.e. there will be in a page that utilizes hotfields to fill in the information in the div. That framework is already built, but the goal is to use that data to define the css values of that div.
There aren't any errors but nothing is happening. It's probably something simple. I appreciate you bearing with me.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function data(){
return parseFloat(document.getElementById('newdata').innerHTML.trim());
}
</script>
</head>
<body>
<div id=sizeChange>
<div id="newdata">
40
</div>
</div>
<script type="text/javascript">
document.getElementById("sizeChange").style.fontSize = data() + "px";
</script>
</body>
</html>
The I trying to change video id 8IYzyTYucKQ to WKV_z36pVAk dynamically but it is not changing.
I think the library bellow only work on page reload so when I clicked the button the new Id changes but the video play the older Id, when I reload the video again Id reset to default one.

You're reloading the page after you change the data attribute using :
location.reload();
What returns the attribute to the default value when the page refreshed and ready again.
Simple example using the API :
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://www.youtube.com/iframe_api"></script>
</head>
<body>
<h3 style="color:#0066dd">Hello</h3>
<button id="change_video">change</button>
<div id="player"></div>
<script>
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '360',
width: '640',
videoId: 'M7lc1UVf-VE'
});
}
$('#change_video').on('click', function(){
player.loadVideoById('WKV_z36pVAk');
})
</script>
</body>
</html>
Hope this helps.
Hello, I am new to HTML and JS therefore would like to ask for some help.
Here I want to display two different HTML elements according if statement is true or false. However, it does not work.
Could I get some help? (:
<!DOCTYPE html>
<html>
<body>
<script>
if (!user) {
<h1> there is no user </h1>
} </script>
if (user) {
<button type="button">Click Me!</button>
} </script>
</body>
</html>
Here is a native Javascript alternative
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id="content"></div>
<script>
var el = document.getElementById('content');
var content;
if (!user) {
content = '<h1>there is no user</h1>';
}
if (user) {
content = '<button type="button">Click Me!</button>';
}
el.insertAdjacentHTML('afterbegin', content);
</script>
</body>
</html>
This won't work as is unless the user variable is defined, though, but I'm assuming you already have it available at runtime.
If you have more html in this div you can use a different insert position, see the documentation about it here: https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML
Using jQuery you would do something like this
html
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
</body>
</html>
JS
if(!user){
$('body').append('<h1>There is no user</h1>')
} else if(user) {
$('body').append('<button>Login</button>')
}
See js fiddle here.
Also, note that if you want to use jquery include the script in the head
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
Unfortunately you can't add HTML directly in a block of javascript. What you can do instead though is use jQuery to append a block of HTML.
To do this, you would load jQuery by adding this line to your head tag
<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js"></script>
And then replace your inline javascript with the following:
<script>
if (!user) {
$(document.body).append( "<h1> there is no user </h1>" );
}
if (user) {
$(document.body).append( "<button type='button'>Click Me!</button>" );
} </script>
I have a div that serves of container for a css animation that appears over the entire website's home page... a text and background that opens like curtains, revealing the website under it. It's like an intro landing page. The thing is I need it to appear only on first page load. I don't want it to appear on page refresh or if someone navigates thru the site and comes back to home page.
Can someone please show me how I would have to code this because I've search a lot on the web and didn't find any clear explanations for my particular case.
Here is the code for the div:
<div id="landContainer">
<div class="left-half" id="leftP"><article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article></div>
<div class="right-half" id="RightP"><article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article></div>
</div>
So the div I must display only on first page load would be the one with the ID landContainer, that contains a couple of other divs.
Since I'm new to this type of coding, I would need a complete example of the code I need to use with my div.
For Ian... here is the content of my index.html file...
<!DOCTYPE html>
<html>
<head>
<title>Landing page v2</title>
<link rel="stylesheet" type="text/css" href="landing.css" media="screen" />
</head>
<body>
<div id="landContainer">
<div class="left-half" id="leftP">
<article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article>
</div>
<div class="right-half" id="RightP">
<article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article>
</div>
</div>
<script type="text/javascript" src="scripts/snap.svg-min.js"></script>
<script scr="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
$( document ).ready(function() {
var isExists = localStorage.getItem("pageloadcount");
if (isExists != 'undefined') { $("#landContainer").hide();
}
localStorage.setItem("pageloadcount", "1");
});
</script>
</body>

}
localStorage.setItem("pageloadcount", "1");
});

<div class="right-half" id="RightP">

</div>
</div>
</body>

The best way is to use session through which you can determine if its a new request or old.
Server side session will be best here
$( document ).ready(function() {
var isExists = localStorage.getItem("pageloadcount");
if (isExists != 'undefined') { $("#landContainer").hide();
}
localStorage.setItem("pageloadcount", "1");
});
<div id="landContainer">
<div class="left-half" id="leftP">
<article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article>
</div>
<div class="right-half" id="RightP">
<article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article>
</div>
</div>
I am having troubles using fadeTo() function in jQuery. It all worked for me at the begining but it stopped working now for some unknown reasons. Here i present you code of webpage. I will appreciate if you can help me.
<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="css/subscribe.css" />
<script type="text/javascript" src="js/jQuery.js"></script>
<script>
$(document).ready(function(){
subscribe = function(){
$('#subscribe').fadeTo(500,1);
};
});
</script>
</head>
<body style="background:#fff;">
+
<div id="subscribe" style="opacity:0;"><?php include('subscribe.php'); ?></div>
<!--<video id="bgvid" width="100%" height="100%" style="position:absolute;opacity:1;" autoplay loop muted>
<source src="css/7dayz.mp4" type="video/mp4"></video>-->
<div id="wrapper_main" style="opacity:1;">
<div id="center_main">
<p>LOOK</p>
<p>SHOP</p>
<p>JOURNAL</p>
</div>
</div>
</body>
</html>
Your code is right. I think the PHP file is not found. I have replaced the PHP include file (Sample Php file):
<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="css/subscribe.css" />
<script type="text/javascript" src="js/jQuery.js"></script>
<script>
$(document).ready(function() {
subscribe = function() {
$('#subscribe').fadeTo(500, 1);
};
});
</script>
</head>
<body style="background:#fff;">
+
<div id="subscribe" style="opacity:0;">Sample Php file </div>
<!--<video id="bgvid" width="100%" height="100%" style="position:absolute;opacity:1;" autoplay loop muted>
<source src="css/7dayz.mp4" type="video/mp4"></video>-->
<div id="wrapper_main" style="opacity:1;">
<div id="center_main">
<p>LOOK</p>
<p>SHOP</p>
<p>JOURNAL</p>
</div>
</div>
</body>
</html>
Your code works : run it here. Click the + , it fades the word "SUBSCRIBE" in.
subscribe = function(){
$('#subscribe').fadeTo(500,1);
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
+
<div id="subscribe" style="opacity:0;">SUBSCRIBE</div>
<div id="wrapper_main" style="opacity:1;">
<div id="center_main">
<p>LOOK</p>
<p>SHOP</p>
<p>JOURNAL</p>
</div>
</div>
Note : you can use .fadeIn() instead of .fadeTo(500,1)
Try this :
(HTML)
+
(JS)
subscribe = function(){
$('#subscribe').fadeIn();
};
$("a#plus").click(subscribe)
You are defining a function but not calling it (EDIT: I did not notice the call in your original code. It should work: http://jsfiddle.net/w3Lr0vgk/) . If you want to use fadeTo at page load simply remove the function:
$(document).ready(function(){
$('#subscribe').fadeTo(500,1);
});
If you want to trigger the fadeTo in another point of your code, simply call the function your defined:
$(document).ready(function(){
subscribe = function(){
$('#subscribe').fadeTo(500,1);
};
subscribe();
});
Your code is working fine. Maybe you have some problem including your php file.
Look at this fiddle
just changed this line
<div id="subscribe" style="opacity:0;">asdasdasdasd</div>
Another thing you can try is (I don't think it's the problem but I don't know what browser you are testing):
