Why when I create several html tags with javascript then I can not delete it with the same javascript?

When I create a form with the write () command, then I want to delete it, but I can't. What is the cause of this problem?
In order to do this correctly, what command should I use or what should I change in my code?
var btn = document.querySelector('#btn');
var btn_alert = document.querySelector('#btn-alert');
var content = document.querySelector('.popup-container');
var div1 = document.getElementById('div1');
function message(message, btn) {
document.write('<div id="div1"><div id="content" class="popup-container"><div class="box-item"><div class="icon-success"><span class="span1"></span> <span class="span2"></span><div class="ring"></div></div><h2 class="alert-title">Good job!</h2><div class="alert-content">' + message + '</div><div class="actions-btn"><button onclick="ok()" class="btn-alert" id="btn-alert">' + btn + '</button></div></div></div></div>')
}
function ok() {
div1.removeChild(content);
}
<button class="btn-alert" id="btn">OK</button>
<!-- <div id="content" class="popup-container dis-active">
<div class="box-item">
<div class="icon-success">
<span class="span1"></span>
<span class="span2"></span>
<div class="ring"></div>
</div>
<h2 class="alert-title">Good job!</h2>
<div class="alert-content">is ok.</div>
<div class="actions-btn">
<button class="btn-alert" id="btn-alert">OK</button>
</div>
</div>
</div> -->
<script src="script.js"></script>
<script>
message("خوش اومدی!", "کلیک کن");
</script>

document.write is really outdated. In your script you write the elements to the document after you're trying to retrieve them. That won't work.
Here is an example snippet using insertAdjacentHTML to create a message element with a button to remove it.
It is generally not a good idea to use inline event handlers. The snippet uses event delegation to handle button clicks.
It may be wise to first learn more about html document manipulation or javascript.
document.addEventListener(`click`, handle);
const create = () => message(`خوش اومدی!`,`کلیک کن`);
create();
function handle(evt) {
if (evt.target.id === `btn-alert`) {
document.getElementById('div1').remove();
}
if (evt.target.id === `recreate`) {
create();
}
}
function message(message, btnTxt) {
document.body.insertAdjacentHTML(`beforeEnd`, `
<div id="div1">
<div id="content" class="popup-container">
<div class="box-item">
<div class="icon-success">
<span class="span1"></span>
<span class="span2"></span>
<div class="ring"></div>
</div>
<h2 class="alert-title">Good job!</h2>
<div class="alert-content">${message}</div>
<div class="actions-btn">
<button class="btn-alert" id="btn-alert">${btnTxt}</button>
</div>
</div>
</div>
</div>`);
}
<button id="recreate">(re)create message</button>

How to detach and append to relevant div only jQuery

I am trying to detach the div from the relevant parent and then append to the same parent div.
//Jquery Code
jQuery(function(){
moveColorDots();
});
function moveColorDots(){
var copyDivData = jQuery('.variations_form.wvs-archive-variation-wrapper').detach();
copyDivData.appendTo('.product-variations');
}
<div class="pp-content-post">
<div class="variations_form wvs-archive-variation-wrapper">
some data here
</div>
<div class="product-box">
<div class="glasses-sec">
<h3>title</h3>
</div>
<div class="product-variations"></div>
</div>
</div>
Expected result.
But after running the above code I am getting the following result.

.detach Description: Remove the set of matched elements from the DOM.
That means you append all the detached elements to every product-variations element ..So
You need to loop through the variations_form.wvs-archive-variation-wrapper elements by using .each()
Also you can use .appendTo() directly
//Jquery Code
jQuery(function(){
moveColorDots();
});
function moveColorDots(){
jQuery('.variations_form.wvs-archive-variation-wrapper').each(function(){
var product_variations = jQuery(this).next('div').find('.product-variations');
jQuery(this).appendTo(product_variations);
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="pp-content-post">
<div class="variations_form wvs-archive-variation-wrapper">
some data here 1
</div>
<div class="product-box">
<div class="glasses-sec">
<h3>title</h3>
</div>
<div class="product-variations"></div>
</div>
</div>
<div class="pp-content-post">
<div class="variations_form wvs-archive-variation-wrapper">
some data here 2
</div>
<div class="product-box">
<div class="glasses-sec">
<h3>title</h3>
</div>
<div class="product-variations"></div>
</div>
</div>
Note: This line of code var product_variations = jQuery(this).next('div').find('.product-variations'); is depending on your html structure it works for the posted html here .. But if you've another html structure you need to modify it to catch the desired element

Link simillary name classes so that when one is clicked the other is given a class

Basically, I'm asking for a way to optimize this code. I'd like to cut it down to a few lines because it does the same thing for every click bind.
$("#arch-of-triumph-button").click(function(){
$("#arch-of-triumph-info").addClass("active-info")
});
$("#romanian-athenaeum-button").click(function(){
$("#romanian-athenaeum-info").addClass("active-info")
});
$("#palace-of-parliament-button").click(function(){
$("#palace-of-parliament-info").addClass("active-info")
});
Is there a way to maybe store "arch-of-triumph", "romanian-athenaeum", "palace-of-parliament" into an array and pull them out into a click bind? I'm thinking some concatenation maybe?
$("+landmarkName+-button").click(function(){
$("+landmarkName+-info").addClass("active-info")
});
Is something like this even possible?
Thanks in advance for all your answers.
EDIT: Here's the full HTML.
<div class="landmark-wrapper">
<div class="page-content landmark">
<div class="heading span-after">
<span>Arch of Triumph</span>
</div>
<div class="landmark-button" id="arch-of-triumph-button"></div>
</div>
</div>
<div class="landmark-wrapper">
<div class="page-content landmark">
<div class="heading span-after">
<span>Romanian Athenaeum</span>
</div>
<div class="landmark-button" id="romanian-athenaeum-button"></div>
</div>
</div>
----------------------------------------------------------
<div class="landmarks-info-wrapper">
<div class="landmark-info" id="arch-of-triumph-info">
<div class="info-landmark section">
<span class="landmark-title">Arch of Triumph</span>
<span class="landmark-coord">44°28′1.99″N 26°4′41.06″E</span>
</div>
</div>
<div class="landmark-info" id="romanian-athenaeum-info">
<div class="info-landmark section">
<span class="landmark-title">The Romanian Athenaeum</span>
<span class="landmark-coord">44.4413°N 26.0973°E</span>
</div>
</div>

Assuming you're not able to modify your HTML markup (in which case with use of CSS classes would be cleaner), a solution to your question would be as shown below:
// Assign same click handler to all buttons
$("#arch-of-triumph-button, #romanian-athenaeum-button, #palace-of-parliament-button")
.click(function() {
// Extract id of clicked button
const id = $(this).attr("id");
// Obtain corresponding info selector from clicked button id by replacing
// last occurrence of "button" pattern with info.
const infoSelector = "#" + id.replace(/button$/gi, "info");
// Add active-info class to selected info element
$(infoSelector).addClass("active-info");
});

Because each .landmark-button looks to be in the same order as its related .landmark-info, you can put both collections into an array, and then when one is clicked, just find the element with the same index in the other array:
const buttons = [...$('.landmark-button')];
const infos = [...$('.landmark-info')];
$(".landmark-button").click(function() {
const i = buttons.indexOf(this);
$(infos[i]).addClass('active-info');
});
This does not rely on IDs at all - feel free to completely remove those from your HTML to declutter, because they don't serve any purpose now that they aren't being used as selectors.
Live snippet:
const buttons = [...$('.landmark-button')];
const infos = [...$('.landmark-info')];
$(".landmark-button").click(function() {
const i = buttons.indexOf(this);
$(infos[i]).addClass('active-info');
});
.active-info {
background-color: yellow;
}

Older answer, without knowing the HTML: You can extract the ID of the clicked button, slice off the button part of it, and then select it concatenated with -info:
$(".landmark-button").click(function() {
const infoSel = this.id.slice(0, this.id.length - 6) + 'info';
$(infoSel).addClass('active-info');
});
A much more elegant solution would probably be possible given the HTML, though.

jQuery works only on first div

Click works just on first div with id plus but other divs with the same id dont work. I dont know whats the problem... I dont get what the problem is. Please help. Thanks!
Here is the code...
Edited:
<div id="details">
<div id="detailHeader">
<div id="facultyTitle">sadasdas</div>
<div id="title">dsadasdasdas</div>
</div>
<div id="detailReference">
dodaj
<div id="refVote">
<div class="plus" glas="41">Good</div>
<div class="minus" glas="41">Bad</div>
</div>
<div id="referenceInfo">
01:40 PM 06.09.2014.
</div>
</div>
</div>
<div id="detailReference">
dodaj
<div id="refVote">
<div class="plus" glas="37">Good</div>
<div class="minus" glas="37">Bad</div>
</div>
<div id="referenceInfo">
01:38 PM 06.09.2014.
</div>
</div>
</div>
JavaScript
$(".plus").click( function() {
var ref=$(this).attr("glas");
alert(ref);
$.ajax({
url:"url is ok",
success:function(){
}
}
);
});

IDs should be unique. use same class instead of ids.Like this:
<div class="plus" glas="37">Good</div>
and then use:
$(".plus").click( function() {
var ref=$(this).attr("glas");
alert(ref);
$.ajax({
url:"url is ok",
success:function(){
}
}
);

$(".plus").click(...)
not
$("#plus").click(...)
There can and shall only be one item with a certain ID on the page. Use classes on those buttons instead.

Couple of issues. You have mismatched divs. This last div looks like its the culprit.
<div id="details">
<div id="detailHeader">
<div id="facultyTitle">sadasdas</div>
<div id="title">dsadasdasdas</div>
</div> <--this one
Your second issue is that you shouldnt have multiple ids that are the same on a page. Instead set it as a class with
<div class="plus"> Then reference them in jquery with
$(".plus").click( function()

I have to use class if you have more than one div. Try with .plus

Javascript click specific to ID

I have a div setup like so:
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
I have the following code:
$('.show-comments').click(function(e){
e.preventDefault();
$('.comments-wrapper').slideToggle('slow');
});
As you would assume, the code works but on a class basis. I'd like for it to open up only the .comments-wrapper of its associated id (i.e. open slideToggle comments2 if content 2 button is clicked and so on and so on).
How would I do this?

$('.show-comments').click(function(e){
e.preventDefault();
$(this).closest(".content").next('.comments-wrapper').slideToggle('slow');
});
Note that this is dependent on the .content element being immediately followed by the .comments-wrapper.
If you have access to modify the html itself, I would suggest adding a wrapper element and then doing the following to avoid the reliance on the exact order of elements:
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
</div>
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
</div>
$(this).closest(".wrapper").find('.comments-wrapper').slideToggle('slow');
This way, if you add an element between the .content and the .comments-wrapper it does not break the code.

You can do this:
$(this).parent("div").next('.comments-wrapper').slideToggle('slow');
This will find the related div of class .comments-wrapper and slide toggle.
And a fiddle: http://jsfiddle.net/xCJQB/

$('.show-comments').click(function (e) {
e.preventDefault();
var num = this.id.match(/\d+$/)[0];
$("#comment" + num).slideToggle('slow');
});
Demo ---> http://jsfiddle.net/7pkyk/1/

Use this context
$(this).closest('.comments').next('.comments-wrapper').slideToggle('slow');
If it is not the immediate element then you might try this as well
$(this).closest('.comments')
.nextAll('.comments-wrapper').first().slideToggle('slow');

you can add a common class to associate a button with a div.
html:
<div class="content">
<button class="show-comments group1" id="content1"></button>
</div>
<div class="comments-wrapper group1" id="comment1">1</div>
<div class="content">
<button class="show-comments group2" id="content2"></button>
</div>
<div class="comments-wrapper group2" id="comment2">2</div>
javascript:
$('.show-comments').click(function(e){
var associate = $(this).attr('class').match(/group\d+/).pop();
var selector = '.comments-wrapper.' + associate;
e.preventDefault();
$(selector).slideToggle('slow');
});
