I'm building a webpag in html. The image must change when I mouse over a div, but it does nothing. Anyone any idea?
<!doctype html>
<html>
<head>
<meta charset ="UTF-8"/>
<title>Oef 19.5</title>
<link href="19_5.css" rel="stylesheet"/>
<script>
function kleuren(veld)
{
var tshirt = document.getElementsByClassName("shirt");
tshirt.src=veld.id+".jpg";
}
</script>
</head>
<body>
<h1>Pick a color</h1>
<p><img class="shirt" src="gray.jpg"></p>
<div id="pink" class="roze" onmouseover="kleuren(this)"></div>
<div id="blue" class="blauw" onmouseover="kleuren(this)"></div>
<div id="brown" class="bruin" onmouseover="kleuren(this)"></div>
</body>
</html>
var tshirt = document.getElementsByClassName("shirt"); returns a collection of elements so access it like
tshirt[0].src=veld.id+".jpg"; //Since you have only one element with that class. If you have more, iterate over them

I am making a website and trying to change the value of active car variable which doesn't change even after click on the division the value of activecar remains as .blueimg only even after clicking on the divisions
What is incorrect?
actions.js file
var activecar=".blueimg";
$(".redimg").hide();
$(".greyimg").hide();
$(".silverimg").hide();
$(".red").click(function(){
hideshow(".redimg",activecar);
});
$(".blue").click(function(){
hideshow(".blueimg",activecar);
});
$(".grey").click(function(){
hideshow(".greyimg",activecar);
});
$(".silver").click(function(){
hideshow(".silverimg",activecar);
});
function hideshow(colour,activecar) {
console.log("before");
console.log(activecar);
$(activecar).hide();
$(colour).show();
activecar = colour;
console.log("After");
console.log(activecar);
}
This is my index.html file

change function's parameter name. It has same name with your global variable.
function hideshow(colour, car) { //activecar changed to car
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.

<script type="text/javascript">
function val1(val)

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 have read through the available links on this topic and they haven't helped.
I'm trying to get the following code to run. The "menu.html" loads the "world.html" in a div on another page, and the HTML comes up, but not the JavaScript.
At first I had the JS in a separate file, but when it wasn't running I moved it into "world.html", but it didn't fix the problem. I have also tried referencing jQuery.
This is menu.html:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="layout.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="contact.js"></script>
<script src="preparePage.js"></script>
</head>
<body>
<a id="infoButton" class="infoButton" href="info.html"></a>
<a id="bodyButton" class="bodyButton" href="body.html"></a>
<a id="enterButton" class="enterButton" onclick="preparePage(); return false;"></a>
<a id="leaveButton" class="leaveButton" href="leave.html"></a>
<a id="contactButton" class="contactButton" onclick="contact(); return false;"></a>
</body>
<footer>
</footer>
</html>
And preparePage.js, which gets rid of the menu and loads world.html:
function preparePage() {
document.getElementById("box").style.backgroundImage = "none";
$("#infoButton").fadeOut("slow");
$("#bodyButton").fadeOut("slow");
$("#leaveButton").fadeOut("slow");
$("#contactButton").fadeOut("slow");
$("#box").load("world.html", function enter() {
$("#enterButton").fadeOut("slow");
});
}
And last but not least, world.html:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function wut() {
window.alert("owo");
}
</script>
</head>
<body onload="wut(); return false;">
mhfkhgfhtfjhfjj<br><br>
<canvas id="gameBox" width="1000" height="500" style="background-color:#ffffff;"></canvas>
</body>
<footer>
</footer>
</html>
EDIT: Also including launchpad.html, which is the page containing the div in which menu.html and world.html load:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" type="text/css" href="layout.css">
<link rel="stylesheet" type="text/css" href="menu.css">
</head>
<body onload="openGame(); return false;">
<div id="cloud"></div>
<div id="box" class="box"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="openGame.js"></script>
</body>
<footer>
</footer>
</html>
And openGame.js, which changes the shape of #box and loads menu.html:
function openGame() {
$("#cloud").fadeOut("fast");
$("#box").animate({
height: '750px',
width: '1700px',
top: '100px',
left: '100px',
padding: '0px'
});
$("#box").load("menu.html");
document.getElementById("box").style.backgroundImage = "url('Images/menuBackground.png')";
}
I would use JQuery for the on-click events, and also make sure that all of the element id's that you reference in your script are present in the page. Another thing to check is that your scripts are loading properly, the letter casing of the file name is important on Linux servers.

Javascript:
$( document ).ready(function() {
$( "#enterButton" ).click(function() {
document.getElementById("box").style.backgroundImage = "none";
$("#infoButton").fadeOut("slow");
$("#bodyButton").fadeOut("slow");
$("#leaveButton").fadeOut("slow");
$("#contactButton").fadeOut("slow");
$("#box").load("/zalun/VkCyH/app.html", function enter() {
$("#enterButton").fadeOut("slow");
})
})
});

Apart from the obvious fact that you don't have an element with the id box, please realise that the jQuery load method will not trigger the onload callback that you have defined in world.html. So you'd need to call that yourself.
So fix two things:
define box, e.g.
<div id="box"></div>
call wut(), from menu.html:
$("#box").load("world.html", function enter() {
wut();
$("#enterButton").fadeOut("slow");
});
The onload= in world.html has no effect when loaded like this, because to the browser there is only one document, which already has loaded. So, there is no second load event triggering.
Alternatively you could just add a script in world.html, near the end just before the closing </body> tag, which will run:
<script>
wut();
</script>
I just started using jQuery, then forgive me for noobish.
What I'm trying to do is 'get reference to a object that is wrapped in a class', but there are more classes with same name.
How can I reach the right object and get the reference to it, when the only thing that will differ it from a thousand other more objects is the text inside the div.
In this case, I'm trying to show only the text "this should be returned", that is under the classes 'ng-anyclass'.
After that, will be possible store the reference to that specific div and change it text? Or any other properties?
Here's the code:
Page 1 - the loader:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">
jQuery(function($){
var s = $('#result').load('Page2.html .ng-anyclass .ng-anyclass .ng-anyclass');
});
</script>
</head>
<body>
<div id="result"></div>
<div>Other Stuff Here</div>
</body>
</html>
Page 2 - the target page
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<div class="ng-anyclass">
<div class="ng-anyclass">
<div class="ng-anyclass">this should be returned</div>
</div>
<div class="ng-anyclass">
<div class="ng-anyclass">not this</div>
</div>
</div>
</body>
</html>
You can use :eq(0) for this:
jQuery(function($) {
$('#result').load('page2.html .ng-anyclass .ng-anyclass .ng-anyclass:eq(0)', function(){
var _this = $(this)
setTimeout(function(){
_this.find('.ng-anyclass').text('changed');
},1000);
});
});
updated plnkr Demo.
If you want to write text somewhere you can use CSS selector, like this :
$('body .ng-anyclass .ng-anyclass:eq(0) .ng-anyclass').text('your text')
eq(0) it's a shortcut of first-child, or eq(1) is nth-child(2) for example
I hope it will be help you
So, as you can see I amusing javascript to show/hide elements, however when you click the .png it shows the text but does not hide the other element's text. I have been going over and over this script and Google searching the hell out of it and I cannot come up with an answer. I think I need another pair of eyes, so if anyone takes a look at this let me know if there are errors or if I'm missing some code.
<html>
<head>
<meta name = "viewport" content = "initial-scale = 1.0, user-scalable = no" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="NKit.js"></script>
<link rel="stylesheet" type="text/css" href="style.css" />
<script type="text/javascript">
function showStuff(id) {
document.getElementById(id).style.display = 'block';
}
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
</script>
</head>
<body>
<div class="content">
<section class="left">
<p>
<img src="character1.png" id="char1" />
</p>
<p>
<img src="character2.png" id="char2" />
</p>
</section>
<section class="right">
<span id="character1" style="display: none;">Show character1 information</span>
<span id="character2" style="display: none;">Character 2 information</span>
</section>
</div>
</body>
</html>
<a href="#" onclick="showStuff('character1');" onclick="hideStuff('character2');">
On this line, you first set the property onclick to showStuff('character1'), then you reassign it to hideStuff('character2').
So, you should wrap these two function calls into one function and then assign that function to onclick.
onclick="function() { showStuff('character1'); hideStuff('character2'); }
