JS toggle for multiple div elements

What should I do if I have multiple elements in HTML foreach and I need to make them all a toggle slider what opens div block with specific information about the element and I need to add close button too if a user wants to close the div. Sorry, I don't have any code to show because I did not find anything that suits my needs. The main idea is to have a product page with products that are displayed on a page using foreach... Then when you click on a product toggle div block is opened with information about a product. What should I search and what to use, I can't find anything because I am limited with my knowledge. Sorry for terrible English.

You can easily control the visibility of an element either within the div you're clicking or after it using a class you toggle. Here's an example controlling the div after one of the divs that controls the toggle:
document.getElementById("container").addEventListener("click", function(e) {
var toggleDiv = e.target.closest(".toggle");
if (toggleDiv && this.contains(toggleDiv)) {
toggleDiv.classList.toggle("closed");
}
});
.closed + .detail {
display: none;
}
<div id="container">
<div class="toggle closed">Product A</div>
<div class="detail">Details about Product A</div>
<div class="toggle closed">Product B</div>
<div class="detail">Details about Product B</div>
<div class="toggle closed">Product C</div>
<div class="detail">Details about Product C</div>
</div>
The key bits there are:
Hiding the details via CSS with the adjacent sibling combinator (+)
Toggling the class on the toggling div
I used event delegation to hook up the handler, but you could instead hook it up to each individual div if you preferred. Note that the Element#closest method I used is relatively new, you may need a polyfill or a loop on parentNode instead.

From what i have understood.
You need to toggle div elements using button tag and the button u click will show that particular div element.
<div id="container1" class={container1 ? "show" : "hide"}>
container1
</div>
<div id="container2"class={container2 ? "show" : "hide"}>
container2
</div>
<div id="container3"class={container3 ? "show" : "hide"}>
container3
</div>
and three button tags to call toggle function to show the three div element.
<div class="container">
<button name="container1" onclick=(toggle())>Container1</button>
<button name="container2" onclick=(toggle())>Container2</button>
<button name="container3" onclick=(toggle())>Container3</button>
</div>
toggle function
function toggle(e) {
if(e.target.name === 'container1'){
container1 = true;
}
else if(e.target.name === 'container2'){
container2 = true;
}
else if(e.target.name === 'container3'){
container3 = true;
}
}
css part
.show{
display: block;
}
.hide{
display: none;
}

Simple Next and Previous Show and Hide with jQuery

I'm trying to figure out the simplest way to show and hide a series of divs with Previous and Next buttons by adding and removing some classes.
So far, I can get the Next button to trigger, but it's adding the active class to all of the divs and not just the next one in line.
I've been reading through other examples and so far they seem really bloated or not what I am looking for specifically.
Here's what I have so far:
Codepen Link: https://codepen.io/ultraloveninja/pen/pxrrmy/
HTML:
<div class="group">
<div class="item active">
<h2>Thing One</h2>
</div>
<div class="item">
<h2>Thing Two</h2>
</div>
<div class="item">
<h2>Thing Three</h2>
</div>
</div>
<div class="btns">
Previous
<a class="btn next" href="#">Next</a>
</div>
JS:
$('.next').on("click", function(){
if($('.item').hasClass('active')) {
$('.item').next().addClass('active');
}
})
CSS:
body {
padding: 10px;
}
.active {
display:block !important;
}
.item {
display:none;
}
It seems like this should be fairly simple, but I can't seem to think of how to target the next div by itself without it showing all of the other ones.

Basically you should get your last active element and activate next after it:
$('.next').on("click", function(){
const $active = $('.item.active');
const $next = $active.next();
if ($next.length) {
$active.removeClass('active');
$next.addClass('active');
}
})
The problem in your current code is that you are getting all items and performing hasClass on all of them so it returns true all the time because there is at least one element with this class and then you are getting next element after each item element and add active class to them so all of your elements are activated in result.

I think you want something like this
$('a.next').on("click", function(){
var a = $('.item.active').last();
a.next().addClass('active');
a.removeClass('active')
});

DIV content hide/show based on URL

In html page am having an div-reportControlPanel as below . I have included another div-reportControlPanel1 as same with different id .
<div id="reportControlPanel" class="pentaho-rounded-panel-bottom-lr pentaho-shadow">
<div id="promptPanel" class="pentaho-rounded-panel-bottom-lr"></div>
</div>
<div id="reportControlPanel1" class="pentaho-rounded-panel-bottom-lr pentaho-shadow">
<div id="promptPanel" class="pentaho-rounded-panel-bottom-lr"></div>
</div>
Here Am show/hide the div's based on url am triggering .
if(prptName == "css.prpt")
{
alert("if");
document.getElementById("reportControlPanel").style.display = 'none';
document.getElementById("reportControlPanel1").style.display = 'block';
}
But as am using same sub Div-promptPanel under two different div my content is not loading properly . promptPanel is pentaho system used div. I am trying to have an another div to modify some css for my prpt.
Thanks.

To reiterate what Moishe said to you already: id are meant to be unique. You currently have two promptPanel id's, which means the second one will likely never be called. Now, you could use javascript, but with minimal knowledge of what your code looks like you could use a simple hash url + some basic css.
$(document).ready(function() {
$('a').click(function() {
$('#url').html($(this).prop('href'));
});
});
div.pentaho-rounded-panel-bottom-lr {
display: none;
}
div.pentaho-rounded-panel-bottom-lr .pentaho-rounded-panel-bottom-lr {
display: block;
}
:target {
display: block !important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="url"></div>
"Open" panel 1
"Open" panel 2
<div id="reportControlPanel1" class="pentaho-rounded-panel-bottom-lr pentaho-shadow">
<div id="promptPanel" class="pentaho-rounded-panel-bottom-lr">
this is some text in the first control panel.
</div>
</div>
<div id="reportControlPanel2" class="pentaho-rounded-panel-bottom-lr pentaho-shadow">
<div id="promptPanel" class="pentaho-rounded-panel-bottom-lr">
this is some text in the second control panel
</div>
</div>

How to change CSS of child element <span> inside parent <div> element Using jQuery onclick event?

I have two menu icons, both classed .menuentry, with the IDs #topicicon and #searchicon, in a menubar. Beneath them are two larger divs, #topiclist and #searchform, both initially set to display:none;.
What I would like to do is click each menu icon and display the corresponding larger div underneath, as well as getting rid of the other larger div if it has been display previously.
So, for example, when I click #topicicon, it displays #topiclist and hides #searchform.
The code is being used on this website, in the menubar at the top: http://bonfiredog.co.uk/bonfog
And this is the code that I am using.
HTML:
<div id="topicicon"><img src="topic_icon.png" /></div>
<div id="searchform"><img src="search_icon.png" /></div>
<div id="topiclist"></div>
<div id="searchform"></div>
CSS:
#topiclist {
display:none;
}
#searchform {
display:none;
}
jQuery:
$("#topicicon").click(function(){
$("#topiclist").css("display", "visible");
$("#searchform").css("display", "none");
}, function(){
$("#formlist").css("display", "hidden");
});
Not working as of now...

You have to make two click handlers for #topicicon and #searchform and use .hide() and .show() as shown :-
$("#topicicon").click(function(){
$("#topiclist").show();
$("#searchform1").hide();
});
$("#searchform").click(function(){
$("#topiclist").hide();
$("#searchform1").show();
});
and you are using two div's with same id's i.e searchform so change the id of second searchform div to say searchform1 and try above code.

You could avoid having to write multiple click handlers, and reuse across different components with the following:
$(function () {
$('.showRelated').click(function () {
var relatedId = $(this).data('rel');
$('.related').hide(); // hide all related elements
$(relatedId).show(); // show relevant
});
});
.related {
display: none;
margin-top: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
<div id="topicicon" class="showRelated" data-rel="#topiclist"><i class="fa fa-newspaper-o"></i></div>
<div id="searchicon" class="showRelated" data-rel="#searchform"><i class="fa fa-search"></i></div>
<div id="topiclist" class="related">Topic List</div>
<div id="searchform" class="related">Search Form</div>

"visible" is not correct value for display propriety. You should add "display: block", or "display: inline-block", or "display: inline" or any other value that is admitted by display propriety.

displaying a group of divs by clicking next and back buttons

I have 5 divs that contain copy.
I have a back and next button, to display each div.
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
// hide the divs, except the first one.
.vote-result { display: none; }
.vote-result.first { display: block; }
The first time the next button link is clicked, I want to remove the off class, to show it as clickable, I probably should disable the link initially too and re-enable it too.
$(".back-btn").removeClass("off");
Once I display the last div, I need to add the off class to the next-btn and disable it.
I thought about using a carousel js plugin to accomplish this, but it is overkill for now.
I know of a way to do this, but it would involve assigning subclasses to the links based on what next or back button was clicked, so it will know what div to show next, as well as removing or adding the off class to the links.
I am hoping to find a solution that allows me to add more div's to display without modifying the code. Any help is appreciated, thank you.

Here is solution for you. I have created Fiddle for your requirement.
HTML code:
<a class="back-btn off">Back</a> | <a class="next-btn">Next</a>
<div class="vote-result first selectedDiv">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result last">
this is the last div
</div>
JS/JQuery Code:
$(".back-btn").click(function(){debugger;
var prevElement=$('.selectedDiv').prev();
prevElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
prevElement.addClass("selectedDiv");
if($('.first').css('display')=="block"){
$(".back-btn").addClass("off");
}
else{
$(".next-btn").removeClass("off");
}
});
$(".next-btn").click(function(){debugger;
var nextElement= $('.selectedDiv').next();
nextElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
nextElement.addClass("selectedDiv");
if($('.last').css('display')=="block"){
$(".next-btn").addClass("off");
}
else{
$(".back-btn").removeClass("off");
}
});
CSS code:
.vote-result { display: none; }
.vote-result.first { display: block; }
.off{display:none;}

Your HTML file:
<html>
<head>
<style>
.vote-result { display: none; }
.vote-result.first { display: block; }
.off {
color: Red;
}
a {
color: blue;
}
</style>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="code.js"></script>
</head>
<body>
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
</body>
</html>
Your new "code.js" file in the same directory:
/**
* The zero-based index of the <div class="vote-result"> element that is currently being shown
* #var {Number}
*/
var activeIndex = 0;
function getNumberOfItems() {
return $('.vote-result').length;
}
function synchronizeInterface() {
var numberOfItems = getNumberOfItems(),
lastIndex = numberOfItems - 1;
$('.vote-result').removeClass('first');
$('.vote-result').each(function(index) {
if (index == activeIndex) {
$(this).addClass('first');
}
})
$('.back-btn').toggleClass('off', activeIndex == 0);
$('.next-btn').toggleClass('off', activeIndex == lastIndex);
}
$(function() {
$('.back-btn,.next-btn').on('click', function() {
// If the button clicked is not deactivated
if (!$(this).hasClass('off')) {
// Determine whether the "Next" button was clicked (otherwise "Back" was clicked)
var clickedNext = $(this).hasClass('next-btn');
// Move the active index in the appropriate direction while not allowing it to fall outside the boundaries of appropriate indices
activeIndex = clickedNext
? Math.min(activeIndex + 1, getNumberOfItems() - 1)
: activeIndex = Math.max(0, activeIndex - 1);
// Make sure the interface now reflects the updated JavaScript variables
synchronizeInterface();
}
return false;
});
});
Some notes: You had an unclosed double-quote for one of your class attributes in your provided HTML. Also, I added some additional styling -- you may want to rename the ".first" CSS class to ".active" instead.

take a look at jquerys .next() function for navigating - jQuery - Next(). you can also check for the last item like this.
if($(this).is(':last-child'))
{
$('.next-btn').removeClass('off');
}else{
$('.next-btn').addClass('off');
}
check everytime a navigation button is clicked and do the same for the first button
