How to cycle between elements in html using JavaScript using buttons

My problem is that I am trying to cycle between HTML elements using buttons. I want to show one element when I press the associated button and hide the other elements.
My current code uses the show and hide from jquery, and I'm not sure if those are the best for what I'm trying to do. I will ultimately use about 14 buttons and 14 different div elements. An array may work better for what I am trying to do.
This code does not show or hide anything upon button press. I would like the code to show the element associated with each button and hide all other elements.
$(function() {
$('div1Button').click(function() {
$('#div1').show();
$('#div2').hide();
$('#div3').hide();
});
$('div2Button').click(function() {
$('#div1').hide();
$('#div2').hide();
$('#div3').hide();
});
$('div3Button').click(function() {
$('#div1').hide();
$('#div2').hide();
$('#div3').show();
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="div1Button">Div1</button>
<button id="div2Button">Div2</button>
<button id="div3Button">Div3</button>
<div id="div1">
Hello Im div1
</div>
<div id="div2">
Hello Im div2
</div>
<div id="div3">
Hello Im div3
</div>

You should use class for your button and your div instead of id and then use data attribute to target which div will show when button clicked.
Example:
$(".toggleButton").on("click", function() {
var target = $(this).data("target");
$(".toggleDiv").hide(); // Hide all div
$(target).show(); // Show the target div
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="toggleButton" data-target="#div1">Div1</button>
<button class="toggleButton" data-target="#div2">Div2</button>
<button class="toggleButton" data-target="#div3">Div3</button>
<div class="toggleDiv" id="div1">
Hello Im div1
</div>
<div class="toggleDiv" id="div2">
Hello Im div2
</div>
<div class="toggleDiv" id="div3">
Hello Im div3
</div>

You forgot to add the # when selecting the buttons.
$(function() {
$('#div1Button').click(function() {
$('#div1').show();
$('#div2').hide();
$('#div3').hide();
});
$('#div2Button').click(function() {
$('#div1').hide();
$('#div2').hide();
$('#div3').hide();
});
$('#div3Button').click(function() {
$('#div1').hide();
$('#div2').hide();
$('#div3').show();
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="div1Button">Div1</button>
<button id="div2Button">Div2</button>
<button id="div3Button">Div3</button>
<div id="div1">
Hello Im div1
</div>
<div id="div2">
Hello Im div2
</div>
<div id="div3">
Hello Im div3
</div>

You should give a css class for your shown div, then hide (or give a "hidden" class to) every other div which doesn't have that class.
It will make your code scalable and less redundant.

How to expand and collapse multiple divs, without repeating the same code using jQuery

I want to write a code that expands and collapses a div with a paragraph, once you click the header text above it.
<div class="container">
<h3><span class="toggler">Text that toggles</span></h3>
<div class="wrapper">
<p>Random text</p>
</div>
</div>
<div class="container">
<h3><span class="toggler2">Text that toggles</span></h3>
<div class="wrapper2">
<p>Random text</p>
</div>
</div>
I am aware that I could write a function like this which would toggle between display: block and display: none.
I could just repeat the same function for different divs with different classes and it would work, but if I have a lot of them I would end up repeating the same function multiple times and I feel like there has to be a much cleaner way to do this.
$(document).ready(function() {
$(".toggler").on("click", function() {
$(".wrapper").toggleClass("active");
});
});

You don't need write single line of code if you use jquery & bootstrap.
Solution 1:
Add reference bnelow:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
your html:
<div class="container">
<h3><span class="toggler" data-toggle="collapse" data-target="#col1">Text that toggles</span></h3>
<div class="wrapper" id="col1">
<p>Random text</p>
</div>
</div>
<div class="container">
<h3><span class="toggler2" data-toggle="collapse" data-target="#col2">Text that toggles</span></h3>
<div class="wrapper2" id="col2">
<p>Random text</p>
</div>
</div>
Solution 2:
Either you can write simple line code
$(document).ready(function() {
$("h3").on("click", function() {
$(this).next().toggleClass("active");
});
});
we can select header with header Tag. After that, we can add toogleClass to just next element that is "DIV".
so, when click header, toggleClass will be added to next element that is DIV

You dont need to repeat it, give both a single class like "toggle-enabled" then instead of using toggler and toggler2 as two function you can put toggle-enabled as one selector and both will run the same function on click.
If you want to only toggle the one selected then use "this" keyword to get current and hide and show that or slide it whatever you want to do but dont need to repeat the code.
Here is your example code working as expected:
$(document).ready(function() {
$(".toggle-enabled").on("click", function() {
var nextdiv = $(this).parent().siblings("div");
nextdiv.is(":visible")?nextdiv.hide():nextdiv.show();
});
});
.togglethis{color:red;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<h3><span class="toggler toggle-enabled">Text A that toggles</span></h3>
<div class="wrapper togglethis">
<p>Random text</p>
</div>
</div>
<div class="container">
<h3><span class="toggler2 toggle-enabled">Text B that toggles</span></h3>
<div class="wrapper2 togglethis">
<p>I have left your toggler2 class in there and you can add more classes to separate it</p>
</div>
</div>

This code should work for your html:
$(document).ready(function () {
$('[class^="toggler"]').on('click', function () {
$(this).closest('.container').children('[class^="wrapper"]').toggle();
});
});
The code looks for any element on your html whose class name starts with toggle. It then attaches an on-click handler function. That function then looks for the affected element's closest ancestor with class name of container. Then from that ancestor/parent, it selects children with class name starting with wrapper. It then toggles the visibility of those children (or child)
You could give your togglers class names of toggleN (where N is any valid class name character) or simply toggle (same class name for all). Similarity, you could name the classes for your wrappers as wrapperN or simply wrapper.

How to select prev no to related element jquery

I would like to slide divs, all of them will have same id because they'll generate inside loop so also trigger has same id. That's why I want to use one function, at the moment function works only for first div and I have no idea how to fix it. I would like that each button would work for div above him.
html part
<div id='slide'>
hello
</div>
<p id='but'>click</p>
<div id='slide'>
hello
</div>
<p id='but'>click</p>
and the js
$(document).ready(function(){
$(this).click(function(){
$("#slide").slideToggle("slow");
});
});

First of all, don't have same ids on one page - use classes instead. If you want to do something with the element before clicked item, you can use prev(), something like this (in your code just change css('color', 'red') to slideToggle("slow"), I have added it just for example):
$(document).ready(function() {
$(".but").click(function() {
$(this).prev().css('color', 'red');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='slide'>
hello
</div>
<p class='but'>click</p>
<div class='slide'>
hello
</div>
<p class='but'>click</p>

Few issues:
Use classes not IDs and use the ID of the click element #but instead of this for your click function
<div class='slide'>
hello
</div>
<p class='but'>click</p>
<div class='slide'>
hello
</div>
<p class='but'>click</p>
$(document).ready(function(){
$('.but).click(function(){
$(".slide").slideToggle("slow");
});
});

Jquery div expands all divs on page

<script type="text/javascript">
jQuery(document).ready(function() {
jQuery(".content").hide();
jQuery(".link").click(function()
{
jQuery("div.content").slideToggle(500);
});;
});
</script>
How to expand only the div which is linked to the specific link?
Edit:
Its done like this
<div class="comment">
<div class="bar">
<a class="link">#</a>
</div>
</div>
<div class="content">
<div class="comment">
<div class="bar">
<a class="link">#</a>
</div>
</div>
</div>

EDIT 2:
You changed your HTML. Now do this:
jQuery(this).closest('div.comment').next('div.content').slideToggle(500);
But wait! Now you have 2 different div.link elements in different relation to .content elements. Is this your actual HTML markup?
You could also do this:
jQuery(this).closest('div.content').slideToggle(500);
Please provide your actual HTML.
EDIT:
Based on updated question, do this:
jQuery(this).parents('div.blaat1').eq(1).next().slideToggle(500);
How to expand only the div which is linked to the specific link?
How are they linked?
If the div is a descendant, do this:
jQuery(this).find('div.content').slideToggle(500);
If the div is a an ancestor, do this:
jQuery(this).closest('div.content').slideToggle(500);
If the div is the next sibling, do this:
jQuery(this).next().slideToggle(500);
If the div is the previous sibling, do this:
jQuery(this).prev().slideToggle(500);
Without seeing your HTML structure, we can only guess at the solution.

For this HTML:
<div class="blaat1">
<div class="blaat1">
<a class="link">#</a>
</div>
<div class="blaat2">
<a class="link">#</a>
</div
</div>
<div class="content">
<div class="otherdivs">
<div class="blaat1_div"><p>Hi – I'm blaat 1</p></div>
<div class="blaat2_div"><p>Hi – I'm blaat 2</p></div>
</div>
</div>
Use this JS:
<script type="text/javascript">
$(document).ready(function() {
$(".content").hide();
$(".link").click(function() {
var blaat = $(this).parent().attr("class");
$(blaat+"_div").slideToggle(500);
});;
});
</script>
I haven't tested that, but it should work.

Try this:
$(".link").click(function(){
$(this).parents('div.content').slideToggle(500);
});;

Toggle single Div layer using jQuery

At runtime I have a loop that creates a number of divs with the same class depending on the number in the database.
<div class="show">....</div>
<div class="show">....</div>
<div class="show">....</div>
I want to display this div using the slideToggle() function with jQuery. For each of these I have a separate hyperlink which when clicked should display the div. Also there are a number of tags in between the hyperlink and the div that I want to toggle.
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
$(function () {
$(".display").click(function(){
$(".show").slideToggle();
return false;
});
});
Naturally when this is called each div layer is toggled, regardless of which hyperlink is clicked. I want to just toggle the div closest to the given hyperlink.
Thanks in advance.

Find the <div> relatively by going from this using tree traversal functions, like this:
$(function () {
$(".display").click(function () {
$(this).next().slideToggle();
return false;
});
});
In this case since it's the next sibling element we care about, use .next(), if the structure is different from the question, you'll need to adjust it accordingly, go get from the <a> you clicked on (this) to the <div> you want to toggle.

$(function () {
$(".display").click(function () {
$(this).next.(".show").slideToggle();
return false;
});

Or while you loop through creating your divs, can you add (for example) a rel value that's incremented by one every time? Giving you something like...
View
<div class="show" rel="1">....</div>
View
<div class="show" rel="2">....</div>
View
<div class="show" rel="3">....</div>
This would then link the two divs so that you could get the rel value of your clicked element and use that to identify the shown / hidden div.
<script type="text/javascript">
$(function () {
$(".display").click(function () {
var element_id = $(this).attr('rel');
$(".show").attr('rel', element_id).slideToggle();
return false;
});
});
