How to add Prev and next buttons to change on outer divs

I have this sample navigation that I'm trying to create. What I want to achieve is when you clicked on prev or next class. The active class will be added to map-inr and the scale_text will also be added to the global_map_location class. I believe that only the eq() function will be used in this part.
Here's my js Code:
// Open Popup
$(".map-inr").on("click", function () {
let myIndex = $(this).closest(".global-map").index() - 1;
$('.map-inr').removeClass('active');
$(this).addClass('active');
$('.global_map_location').removeClass('scale_text');
$(this).closest(".global-map").find('.global_map_location').addClass('scale_text');
if ($(".map-item.is--show").length) {
$(".map-item").removeClass("is--show");
setTimeout(function () {
$(".map-item").eq(myIndex).addClass("is--show");
}, 600);
} else {
$(".map-item").eq(myIndex).addClass("is--show");
}
});
//Next function
$('.next').click(function(){
if ($('.is--show').next('.map-item').length) {
$('.is--show').removeClass('is--show')
.next('.map-item')
.addClass('is--show');
}
});
//Prev function
$('.prev').click(function(){
if ($('.is--show').prev('.map-item').length) {
$('.is--show').removeClass('is--show')
.prev('.map-item')
.addClass('is--show');
}
});
.global-map {
display: inline-block;
vertical-align: top;
margin-right: 20px;
margin-bottom: 20px;
}
.map-inr {
background: red;
width: 150px;
height: 150px;
cursor: pointer;
}
.map-inr.active {
background: yellow;
}
.global_map_location.scale_text {
font-weight: 600;
}
.contain {
width: 100%;
max-width: 1000px;
margin: 50px auto 0;
padding: 0;
}
.map-item {
display: inline-block;
vertical-align: top;
padding: 20px;
border-radius: 20px;
text-align: center;
}
.map-item.is--show {
background: yellow;
}
.slider-arrow-wrapper {
margin-bottom: 20px;
}
.slider-arrow-wrapper .prev,
.slider-arrow-wrapper .next {
display: inline-block;
vertical-align: top;
text-decoration: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="global-map">
<div class="map-inr active"></div>
<p class="global_map_location scale_text">map1</p>
</div>
<div class="global-map">
<div class="map-inr"></div>
<p class="global_map_location">map2</p>
</div>
<div class="global-map">
<div class="map-inr"></div>
<p class="global_map_location">map3</p>
</div>
<div class="contain">
<div class="map-item is--show">
<div class="slider-arrow-wrapper">
prev
next
</div>
1
</div>
<div class="map-item">
<div class="slider-arrow-wrapper">
prev
next
</div>
2</div>
<div class="map-item">
<div class="slider-arrow-wrapper">
prev
next
</div>
3</div>
</div>
I have tried this on next button:
//Next function
$('.next').click(function(){
let nextIndex = $(this).closest(".map-item").index() + 1;
console.log("This next is " + nextIndex);
$(".global-map").eq(nextIndex).find('.map-inr').addClass("active");
$(".global-map").eq(nextIndex).find('.global_map_location').addClass("scale_text");
if ($('.is--show').next('.map-item').length) {
$('.is--show').removeClass('is--show')
.next('.map-item')
.addClass('is--show');
}
});
But it just keeps adding classes to next div. How to remove the classes from prev sections/divs? Is there any proper way to do it?

When user click on Prev and Next anchor tag which have Yellow background then only it should work. It is not feasible solution to make all the prev and next anchor tag click work. Only yellow background prev and next click should work.
Below is the code which match up the scenario which is explained above and also it will give you the user friendly standard view:
$(".next").on('click', function(e) {
e.preventDefault();
if($(this).closest(".map-item.is--show").next().length > 0)
{
$(".contain .is--show").removeClass('is--show').next().addClass("is--show");
$(".map-inr.active").removeClass('active').parent().next().children(".map-inr").addClass("active");
}
});
$(".prev").on('click', function(e) {
e.preventDefault();
if($(this).closest(".map-item.is--show").prev().length > 0)
{
$(".contain .is--show").removeClass('is--show').prev().addClass("is--show");
$(".map-inr.active").removeClass('active').parent().prev().children(".map-inr").addClass("active");
}
Please replace it with your prev and next click jQuery.
Let me know if you have any issues or modification request.

onclick with condition from none to apply

I have problem that I need help with
I put a simple exemple of my code from w3schools to make it more simple.
I have a tab gallary with 4 images, that you can click on an image so it will get viewed bigger under.
This thing is working with onclick function.
What I want is to make the onclick= none until a condition happened (if text is contains something in this exemple.
I made the image onclick = none and the condition to be true so the myFunction(this). In other word to make the image clickable to get viewed under, but this is not working.
Sorry for my bad explanation,check the code and you will get it fast.
I just want to be able to activate the clicking on the image when a condition is true.
function myFunction(imgs) {
var expandImg = document.getElementById("expandedImg");
var imgText = document.getElementById("imgtext");
expandImg.src = imgs.src;
imgText.innerHTML = imgs.alt;
expandImg.parentElement.style.display = "block";
}
var mytextvar= document.getElementById("mytext").textContent
if(mytextvar == "keyboard"){
document.getElementById("mytext").onclick = "myFunction(this);"
}
* {
box-sizing: border-box;
}
body {
margin: 0;
font-family: Arial;
}
/* The grid: Four equal columns that floats next to each other */
.column {
float: left;
width: 25%;
padding: 10px;
}
/* Style the images inside the grid */
.column img {
opacity: 0.8;
cursor: pointer;
}
.column img:hover {
opacity: 1;
}
/* Clear floats after the columns */
.row:after {

display: table;
clear: both;
}
/* The expanding image container */
.container {

}

}
var imgs = document.querySelectorAll(".img-cls");
imgs.forEach((img) => {
img.addEventListener('click', function(event) {
checkStatus(this);
});
});
function doImgAction(source, type) {
if (source.classList.contains(type)) {
showImage(source);
} else {
alert("You don't have enough credits to perform this action!");
}
}
function checkStatus(source) {
var mytextvar = document.getElementById("mytext");
var myText = mytextvar.textContent.toLowerCase();
switch (myText) {
case "sliver":
{
doImgAction(source, 'sliver');
break;
}
case "gold":
{
doImgAction(source, 'gold');
break;
}
case "diamond":
{
doImgAction(source, 'diamond');
break;
}
default:
{
return;
}
}
}

You are using a conditional for adding an onclick event:
if(mytextvar == "keyboard"){
document.getElementById("mytext").onclick = "myFunction(this);"
}
However, when the condition mytextvar == "keyboard" is true, the event will be added and then it would never be deactivated, because you never deactivate it in the code.
What you can do is to move the conditional inside the function, so js would check the conditional every time an image is clicked, and then the code would be executed or not depending on the condition
function myFunction(imgs) {
var mytextvar= document.getElementById("mytext").textContent
// If condition is false, return of the function
if(mytextvar != "keyboard")
return;
var expandImg = document.getElementById("expandedImg");
var imgText = document.getElementById("imgtext");
expandImg.src = imgs.src;
imgText.innerHTML = imgs.alt;
expandImg.parentElement.style.display = "block";
}
document.getElementById("mytext").onclick = "myFunction(this);"
Note: the event would always be executed, but you return early if the condition is false

Mouse on one element and another do the action and only the other one has action. (html)

Mouse on one element and another do the action, and only the other one has action.
I want to make a mouse on and change background colour effect, but it works on only one.
Whatever the mouse is pointing on, only one will change the colour.
Here is the code (HTML with JS)
<div class = science style = "position:absolute; left:20px">
<script language="javascript">
function hightback() {
document.getElementById("part1").style.backgroundColor = "#744e4e";
}
function removehightback() {
document.getElementById("part1").style.backgroundColor = "#524c44";
}
</script>
<button id = "part1" onclick="window.location.href='science.html';" value="science" onmouseover="hightback()" onmouseout="removehightback()">
<div class = science1 style = "position:absolute; left:40px; top:45px;">
<h1>Science</h1>
</div>
</button>
</div>
<div class=art style="position:absolute; left:280px">
<script language="javascript">
function hightback() {
document.getElementById("part2").style.backgroundColor = "#744e4e";
}
function removehightback() {
document.getElementById("part2").style.backgroundColor = "#524c44";
}
</script>
<button id="part2" onclick="window.location.href='art.html';" value="art" onmouseover="hightback()" onmouseout="removehightback()">
<div class=art1 style="position:absolute; left:40px; top:45px;">
<h1>Art</h1>
</div>
</button>
</div>
Here is the CSS:
.science1 h1 {
color: #b6ab8f;
size: 55;
font-family: "Josefin Sans", sans-serif;
text-align: left;
}
.science button {
border-radius: 50px;
background: #524c44;
padding: 20px;
width: 230px;
height: 300px;
}
.art1 h1 {
color: #b6ab8f;
size: 55;
font-family: "Josefin Sans", sans-serif;
text-align: left;
}
.art button {
border-radius: 50px;
background: #524c44;
padding: 20px;
width: 230px;
height: 300px;
}

You overwrite your functions for part2. Why not make one unique function for all elements?
Please check below example:
function changeBgColor(id, color) {
document.getElementById(id).style.backgroundColor = color;
}
And now you can use them in such way
<button id="part1"
onclick="window.location.href='art.html';"
value="art"
onmouseover="changeBgColor('part1', '#744e4e')"
onmouseout="changeBgColor('part1', '#524c44')" >
<div class=art1 style="position:absolute; left:40px; top:45px;">
<h1>Art</h1>
</div>
</button>
<button id="part2"
onclick="window.location.href='art.html';"
value="art"
onmouseover="changeBgColor('part2', '#744e4e')"
onmouseout="changeBgColor('part2', '#524c44')" >
<div class=art1 style="position:absolute; left:40px; top:45px;">
<h1>Art</h1>
</div>
</button>
Also you can simplify your code and instead of js use css styles
#part1, #part2 {
backgound-color: #524c44;
}
#part1:hover, #part2:hover {
backgound-color: #744e4e;
}

Your problem here is overlapping JS code as it is calling the second version of the function in the next script tag. I suggest using css hover instead.
Example:
#part_1:hover {
background-color: black;
}

Button click Triggers Text Below

I want to set up a functionality for a button that causes text to appear underneath it on click.
For example, when you click a button that says "Sign up now", text would appear underneath the button that says "Are you a member, yes or no?".
"Yes" and "No" would be links that bring you to a different page depending on how you answer.
My button code so far (just html and styling done):
<a href="/ticket-link" target="_blank" class="ticket-button">Sign Up
Now</a>
I'm new with this kind of functionality so any help would be greatly appreciated!
Thanks!

Adjust the href attribute as you want.
$('#btn').click(function() {
$('#modal').fadeIn();
});
a {
display: block;
text-decoration: none;
color: white;
background-color: #333;
width: 100px;
padding: 20px;
border-radius: 5px;
margin: 0 auto;
}
#modal {
width: 300px;
height: 120px;
background-color: #ccc;
border-radius: 5px;
margin: 0 auto;
display: none;
}
#modal h3 {
text-align: center;
padding: 10px;
}
#modal a {
width: 50px;
display: inline-block;
text-align: center;
margin: 0 auto;
height: 10px;
vertical-align: middle;
line-height: 10px;
}
.btns {
width: 200px;
margin: auto;
}
a:hover {
background-color: #666;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="/ticket-link" target="_blank" class="ticket-button" id='btn'>Sign Up Now</a>
<div id='modal'>
<h3>Are you a member?</h3>
<div class='btns'>
Yes
No
</div>
</div>

You could use the onClick function to unhide text, or elements, below it.
Sign Up Now
<span style="display:none;" id="text">This is some text :D</span>

simple way:
Sign Up Now
<script>
function confirmSignup(){
if(confirm("Are you sure?"))
{
window.location.href="http://somelocation.com/sign-up";
}
}
</script>

Like #Pety Howell said, you can use the onClick function to unhide the text. Here's a pretty straightforward way to do it with jQuery.
$(function() {
$('.link').on('click', function() {
$('.span').addClass('open');
});
});
.span {
display: none;
}
.open {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Click me
<span class="span">I'm hidden!</span>
Working fiddle: https://jsfiddle.net/3gr03yzn/4/

You could use jQuery toggle() function.
HTML :
<button id="member">
Are you Member ?
</button>
<div class="answer">
Yes<br />
No
</div>
JS :
$("#member").click(function() {
$(".answer").toggle();
});
CSS :
.answer {
display:none;
}
The working example on jsFiddle.
Hope this helps

Try this code.

function execute(){
var x = document.getElementById('link_list');
var y =document.getElementById('btn');
if(x.style.visibility==="hidden"){
y.style.visibility="hidden";
x.style.visibility="visible";
}
}
<button onclick="execute()" id="btn">sign up</button>
<div id="link_list" style="visibility:hidden">
Are you a member, <button onclick="window.open('http://sparrolite.blogspot.in')">Yes</button> or <button onclick="window.open('google.com')">no</button>
</div>

Most answers mentioned here either uses
jQuery or,
onclick attribute which is obtrusive javascript.
Here's how to achieve the desired behavior using vanilla, unobtrusive JavaScript.
window.onload = function() {
var button = document.querySelector('.ticket-button');
var info = document.querySelector('.info');
info.style.display = 'none';
var dispalyInfo = false;
button.onclick = function(e) {
e.preventDefault(); /* prevent page from navigating to a new page onclick */
if (dispalyInfo) {
info.style.display = 'none';
dispalyInfo = false;
} else {
info.style.display = 'initial';
dispalyInfo = true;
}
}
}
.ticket-button {
display: block;
}
Sign Up Now
<span class="info">Are you a member, yes or no?</span>

I am trying to display a div on click of a checkbox

I need to display an image and some info about the item when a checkbox is clicked. For some reason nothing is happening and I have been tweaking this for a while with no response whatsoever.
Here is my javascript:
<script type = "text/javascript">
function displayOnChecked(var checkboxID, var id) {
if(document.getElementById(checkboxID)) {
document.getElementById(id).style.display = "block";
} else {
document.getElementById(id).style.display = "none";
}
}
</script>
In the stylesheet I have it on display: none;
Here is one of my invocations:
<input type="checkbox" name="purchasedItem" id = "item" onclick="displayOnChecked('item', 'itemInfo');">

No need for the var keyword in the arguments list of displayOnChecked, just have the variable names alone.
If you look in your console, you should be getting an error: Uncaught SyntaxError: Unexpected token var

You don't intialize variables as function arguments:
function displayOnChecked(var checkboxID, var id)
should be
unction displayOnChecked(checkboxID, id)

You can achieve this, just using the CSS pseudo-element :checked:
.checkmeout {
display: none;
position: absolute;
top: 12px;
left: 150px;
width: 400px;
height: 100px;
padding: 12px;
color: rgb(255,255,255);
background-color: rgb(255,0,0);
}
.checkmeout img {
display: block;
width: 200px;
height: 50px;
background-color: rgb(0,0,255);
}
.checkme:checked ~ .checkmeout {
display:block;
}
<form>
<input type="checkbox" name="checkme" class="checkme" /> Check Me
<div class="checkmeout">
<img src="" alt="Check Me Out Image" />
<p>Check Me Out Text Description</p>
</div>
</form>
