I have a div tab that contains some text and an svg icon like so
Once I click that tab then it expands like so
Once expanded I want the svg icon to change to something else. So far my code isn't throwing me any errors but also isn't working as expected either. I currently have a function that should change the icon to icon-cancel.svg after the element is clicked nothing changes. Here is what I have.

Your "side-chat" element is the <a> tag which does not have a src.
Try changing getElementById to querySelector to get the image inside instead.
function changeImage(){
document.querySelector('#side-chat img').src = "icon-cancel.svg";
}
after opening the code inside the svg file
path
Copy everything between the svg codes. Then add an onclick event. I think your problem will be solved if you add a click event like svg.innerHTML = what you copied when clicked. Since svg files consist of vectors, the path codes in them determine the icon. When it changes, the icon will also change. I hope I could help.
var svg = document.querySelector('.svg');
svg.addEventListener('click',()=>{
svg.innerHTML=`

In your function you are changing the src of an <a> tag. But you want to change it from the <img> tag. So your selector is wrong.
document.getElementById('side-chat') - outputs the <a> tag
Just add an id to the <img> tag and select this id.
Then you can
document.getElementById('imgId').src = "other img path"
Inside your changeImg() function.

In the top left corner of this page, I have a "Light/Dark mode" toggle. When 'Light mode' is clicked, it fades into dark mode nicely no problem. But once it's in Dark mode, and you click 'light mode', it doesn't fade in nicely and I can't seem to get it to work.
What would I need to add to my code to get it to fade nicely in to light mode?

You need to apply the tranition effect to the elements affected by your dark theme, not the dark-mode class itself. You did it right for the #dark-mode-button though.
Solution for your code: add a transition (transition: all 0.5s ease-in-out) on html{} and .tabs a {}, and you can remove the transition effect on the dark-mode class. Fiddle: https://jsfiddle.net/40y5axcd/
Note: you applied a white text color to the whole html for dark mode, hence your main content text isn't visible on a white background. I left it as is, since it wasn't a part of your question.
Going forward you're better off using an utility class with the transition effect and apply it to all elements affected by the dark mode, especially if you continue to add elements to your page and want to change the transition duration. You rather only have to change one class, then having to go through every element and change the duration.
Is it possible to implement my code by changing only the check box to a button in the same way as the function?And how do I make js code onclick instead of css? Could you tell me both?
<style>
* {
padding:0;margin:0;
}
.sidebar{
width:300px;height:100%;
background:#f5f5f5;
position:fixed;top:0;
right:-300px;z-index:1;
transition:all .35s;}
#menuicon:checked + div {
right:0;
}
</style>
<input type="checkbox" id="menuicon">
<div class="sidebar">
</div>
I tried to implement the onclick function by changing the check box to a button and using javascript, but the function did not work I want to make it with JavaScript only
Look at the code below...
First in HTML
In the markup, we have a sidebar open button class="opened", a sidebar close button button class="closed" and the sidebar itself div class="sidebar" inside the aside semantic tag. Note that the close button for the panel is inside the panel itself. Those. it appears on the user's screen only when the panel is open, which is logical.
Now take a look at the CSS
The visual styles of the buttons are not particularly interesting. Interesting sidebar styles. It is positioned fixedly relative to the browser window. In order for the panel to occupy the entire height of the screen, the top: 0 and bottom: 0 properties are set. In addition, by default, we hide the panel outside the visible area using our transform: translateX(-100%) property. The percentage sizes for this property are calculated based on the size of the block to which it is applied. Those. -100% shifts the panel to the left by its full width.
Notice the .sidebar.active selector. It will take effect when the sidebar has both the .sidebar class and the .active class. In this selector, we remove the shift of the sidebar outside the visible area. This means that the sidebar with the .active class is visible to the user.
Now let's take a look at JS
First, we define the identifiers of the elements we need - the open, close and sidebar buttons. This will be needed for what follows. Obviously, when the open button is clicked, we need to add the active class to the sidebar. We defined the function of adding this class for the click event in the addEventListener method.
On the close button we hang a click listener and a deletion function of the .active class for the sidebar.
Here's a simple technique.
const open = document.querySelector('.opened');
const close = document.querySelector('.closed');
const sidebar = document.querySelector('.sidebar');
open.addEventListener('click', () => {
sidebar.classList.add('active');
});
close.addEventListener('click', () => {
sidebar.classList.remove('active');
});
body {
margin: 0;
}
.opened,
.closed {
border: none;
padding: 0;

display: flex;

}
.sidebar {

}

}

I'm trying to make a navbar similar to the one on Linus Tech tips (https://linustechtips.com/main/) for a school assignment. I'm at the real basic level of Javascript and I cooked up a pinnable navbar but when I made it there was no banner above it. Now there is a banner above it and I don't know how to make the navbar push to the top when I start scrolling.
Here is my HTML:
<div class="navContainer">
<div class="topBanner">
<img src="images/topbanner.png" id="topBannerimg"/>
</div>
<div id="navbar">
<button onclick="pinfunc()"><i id="pin" class="fa fa-thumb-tack fa-2x navButton" id="pinbtn" aria-hidden="true"></i></button>
</div>
</div>
Here is my Javascript:
var pinned = 1;
console.log(pinned);
function pinfunc() {
if (pinned == 1) {
document.getElementById("navbar").style.position= "relative";
document.getElementById("pin").style.color = "black";
document.getElementById("pin").style.transform = "rotate(0deg)";
pinned=0;
}
else if (pinned == 0) {
document.getElementById("navbar").style.position="fixed";
document.getElementById("pin").style.color = "red";
document.getElementById("pin").style.transform = "rotate(270deg)";
pinned=1;
}
}
And here is my CSS:
body{
margin: 0 auto;
}
.navContainer{
width: 100%;
margin: 0 auto;
}
#topBannerimg{
width: 100%;
margin: 0;
display:block
}
.navButton{
height: 25px;
width: 25px;
}
.fa-thumb-tack{
font-size: 50px;
color: red;
transform: rotate(270deg);
}
.container{
height: 1000px;
width: 90%;
margin: 0 auto;
}
#navbar{
height: 50px;
width: 100%;
position: fixed;
margin: 0 auto;
background-color: #D35300;
}
#nav{
background-color: #D35300;
height: 50px;
}
I'm just looking to create a basic one of the LTT forum - no need for the toggle button to fade out or anything.
This is my first post so I'm not 100% sure how to do stuff.
Thanks in advance.
If you are allowed to use external JS or CSS libraries, then try the Affix plugin for bootstrap. (link: http://www.w3schools.com/bootstrap/bootstrap_affix.asp). It makes what you are trying to accomplish simple.
If you are not allowed to use any external libraries then, I suggest you read this: http://getbootstrap.com/javascript/#affix-examples and try to implement it yourself.
Good Luck!
So I got it working with the following HTML, JS, and CSS files:
HTML
<html>
<head>
<link rel="stylesheet" href="path/to/font-awesome.css/file" type="text/css">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<!-- Custom CSS File Below -->
<link href="/path/to/custom/css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="topBanner">
<img src="images/topbanner.png" id="topBannerimg"/>
</div>
<div id="navbar" data-spy="affix" data-offset-top="100">
<button onclick="pinfunc()"><i id="pin" class="fa fa-thumb-tack fa-2x navButton" aria-hidden="true"></i></button>
</div>
<div id="SpaceFiller"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<script src="path/to/custom/js/file"></script>
</body>
</html>
The key things to learn from this HTML are the loading the JS files at the bottom of the body tag so the page can load first, and the order in which the CSS and JS files are loaded. The SpacFiller div is just there to enable scrolling. Also, note that I removed your navbar-container as it didn't seem necessary.
Javascript
var pinned = true;
function pinfunc() {
var $pin = $("#pin");
var $navbar = $("#navbar");
if (pinned) {
$pin.css({
'color': 'black',
'transform': 'rotate(0deg)'
});
console.log("not pinned")
$(window).off('.affix');
$navbar.removeClass('affix affix-top affix-bottom');
$navbar.removeData("bs.affix");
pinned = false;
} else {
$pin.css({
'color': 'red',
'transform': 'rotate(270deg)'
});
$(window).on('.affix');
$navbar.addClass('affix');
$navbar.affix({
offset: 100
});
pinned= true;
}
}
This JS uses jQuery Selectors (which actually uses sizzle.js I believe) to get access to HTML elements via their IDs. Using the returned jQuery object, the function sets the appropriate CSS and then toggles affix using functions you can read about here: http://getbootstrap.com/javascript/#affix, https://api.jquery.com/removeclass/, https://api.jquery.com/jQuery.removeData/, http://api.jquery.com/off/. Also, you were using 0 and 1 for the pinned values but it is good practice to use boolean values (true and false) as shown.
CSS
body{
margin: 0 auto;
}
.affix {
top: 0;
width: 100%;
}
.affix + .container-fluid {
padding-top: 70px;
}
#topBannerimg{
width: 100%;
margin: 0;
display:block;
height: 100px;
top: 0px;
}
.navButton{
height: 25px;
width: 25px;
}
.fa-thumb-tack{
font-size: 50px;
color: red;
transform: rotate(270deg);
}
#navbar{
height: 50px;
width: 100%;
margin: 0 auto;
background-color: #D35300;
}
#SpaceFiller {
height: 10000px;
background-color: darkgreen;
}
I think the CSS is self-explanatory, but if it is unclear go ahead and ask for clarification. Hope this helps! :D
Edit: You can also put the onclick attribute on the i tag itself and get rid of the button wrapper if you want to get rid of the white button background.
I am trying to build a simple web page for my website using HTML, CSS, JavaScript and JQuery. What I want is to display a slideshow of a few of my images at the top of the page. I just want the pictures to fade out and fade in after one another forever until the user closes the browser. I want each picture to be displayed for a certain amount of time, after which it will fade out and another picture would fade in.
I referred to this as well as this post on SO but couldn't find a solution. I got some idea from this page and tried to develop some code.
The overall layout of the website is as follows:
For this, my index.html page looks like this:

background-color: transparent; color: #d0d0d0;
font: normal normal 11px verdana; margin: 0 auto;
}
#wrapper {
background-color: transparent; width: 960px; margin: 0 auto;
}
#headerlogo {
border-radius: 0px 0px 5px 5px; display: block;
width: 960px; height: 350px;
background-color: #d0d0d0;
}
#container {
width: 100%; margin-top: -35px;
}
#nav {
background-color: transparent;
color: #888888; border-radius: 5px; padding: 10px;
width: 100%; position: relative; top: -40px;
}
#nav>a {
border-radius: 5px; display: inline-block; padding: 5px 19px;
font-weight: bold; border: 1px solid transparent;
color: #888888; background: none none transparent no-repeat;
}
#nav>a:link {
text-decoration: none; border-color: transparent; background-image: none;
}
#nav>a:visited {
text-decoration: none; border-color: transparent; background-image: none;
}
#nav>a:hover{
text-decoration: none; border-color: #ffa500; background-image: url("/img/1x30_ffa500.gif");
background-repeat: repeat-x; box-shadow: 0px 0px 5px #ffd700;
}
#nav>a:active {
text-decoration: underline; border-color: transparent;
background-image: none;
}
#content {
background-color: #f0f0f0; color: #202020;
padding: 5px; border-radius: 5px;
}
The common.js file is like this:
$(document).ready(function (){
var images = new Array();
images[0] = new Image();
images[0].src = "img/coverpics/sea_link.jpg";
images[1] = new Image();
images[1].src = "img/coverpics/marine_drive.jpg";
images[2] = new Image();
images[2].src = "img/coverpics/backbay.jpg"
banner_rotator("headerlogo", images, 0);
});
And, the banner_rotator.js file is like this:
function banner_rotator(imgid, imgarray, imgpos) {
setInterval(function() {
if (imgpos >= imgarray.length || imgpos == undefined)
imgpos = 0;
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000, "linear");
$("#"+imgid).delay(6500);
$("#"+imgid).fadeOut(500);
// $("#imgposspan").html(imgpos);
imgpos++;
}, 8000);
}
Now, my problem description is as follows:
For the first few seconds the top portion is blank. The image is not showed, even though I am developing and having all the files on my local machine itself.
This first image directly pops up on the screen, instead of fading in.
After this image fades out, the image block vanishes, as if it is set to display: none; for a second. The entire page that follows the image shifts up. Then, the next image fades in and so forth everything runs normal.
Hence, in short, I have problems with the starting of this slideshow. Can anybody please help?
Also please tell me where can I put my code so everybody here can access and see for themselves how it runs?
JSFIDDLE
<img id="headerlogo" />
Don't do that (an image tag with no src attribute)
Put a div that will hold the space (set position:relative with width & height in css)
Then the problem is that you are changing your src attribute in your time loop, this ain't smooth
In your CSS, suppose you name your slider wrapper headerlogo_wrapper
div.headerlogo_wrapper > img {position:absolute;display:none;left:0;top:0}
Then you append your images to the space holder you have created (they will not show obviously)
Then you fadeIn your first image then you launch your setInterval :
//after having appended the images to the slider wrapper :
var $img = $("div.headerlogo_wrapper > img");
$img.eq(0).fadeIn(1000, "linear");
var ivisible = 0;
setInterval( function() {
$img.eq(ivisible).fadeOut(500);
++ivisible;
if (ivisible>$img.length-1) ivisible = 0;
$img.eq(ivisible).stop().fadeIn(1000, "linear");
}, 8000);
(If you want an image to be shown during load, some simple changes shall do; also if the first interval start immediately you obviously don't need to fadeIn "manually" the first image)
Try this: http://jsfiddle.net/3XV5M/
Your problem is the first time you run the timer function it won't run straight away. It will be run after 8000ms. The way this fiddle works is it will execute the function immediately and the run itself again after 8 seconds. Note I'm using setTimeout instead of setInterval.
function banner_rotator(imgid, imgarray, imgpos) {
if (imgpos >= imgarray.length || imgpos == undefined) imgpos = 0;
$("#"+imgid).attr({ "src" : imgarray[imgpos].src })
.fadeIn(1000, "linear")
.delay(6500)
.fadeOut(500);
imgpos++;
setTimeout(function() {banner_rotator(imgid, imgarray, imgpos) }, 8000);
}
The other problem is you need to hide the images first, so they can fade in. They wont fade in if they are already visible.
#headerlogo {
border-radius: 0px 0px 5px 5px;
width: 960px; height: 350px;
background-color: #d0d0d0;
display: none; /* Add this */
}
Then to prevent the other elements jumping up when you fade the images out, wrap the image element inside a div and set it's height. I used a div with a class of banner and added this style:
.banner {
height: 350px;
}
Hope that helps.
The problem is that you are fading out at the end of your interval. So replace this:
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000, "linear");
$("#"+imgid).delay(6500);
$("#"+imgid).fadeOut(500);
with this:
$("#"+imgid).fadeOut(500)
$("#"+imgid).queue(function(){
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000);
$("#imgposspan").html(imgpos);
imgpos++;
$(this).dequeue();
});
JSFIDDLE demo
I have 5 diffrent backgrounds which change from one to another when mouseover menu links like that:
3 different screenshots out of 5
I want that the web site works properly in all browsers, but I get very different results. In firefox, background image dissapears and reappears on each menu link, but only first time when I go over a link with a cursor, other times works fine. In chrome backgrounds disappear and reappear on every onmouseover. And in IE onmouseover doesn't work at all nor the menu.
So I'm asking you to help me fix this, both things, dissapearing and the menu in IE. I found out that this disappearing and reappearing happens because of slow image loading, but I have no idea how to repair my code to fix this.
I just wrote my code in jsFiddle and menu doesn't work in it as well. And I noticed that when I downscale windows into the size smaller than div, the whole thing starts to deform. I thought I already fixed it, but it seems that I don't know how to that as well. You can see my code here:

For blinking background images, and other images which you want to use from JS, you need to preload, or it will be blinking. How to preload an image? Click here
(It's blinking, because when the page was loaded, the image wasn't. So, that image which you want to use, isn't at the user. The browser download it, but until that time, theres no image what it can show for him/her. This is the reason.)
IE is blocking JS in default (like IE 10). You need to enable it. I've got a warning bubble an the bottom, which say, I've blocking everything... or something like that. You can't enable this from script. Only you can create a warning message for the user, which you remove if JS is enabled.
An extra thing, in jsFiddle it will work the page if you select the "no warp - in <head>" option from the second drop down list at top left. After that you need to click run at top.
