How to add inline CSS to dynamically created elements with Javascript?

I would like to add inline CSS to the left and right messages that are generated, for example the left text is red and the right text is blue. (I know it's best to style in the CSS, but I'm testing something else). So I will have this HTML:
<ul class="messages">
<li class="message left appeared">
<div class="text_wrapper">
<p class="text" style="color:red;">blabla</p>
</div>
</li>
<li class="message right appeared">
<div class="text_wrapper">
<p class="text" style="color:blue;">blabla</p>
</div>
</li>
</ul>
Please see the code as reference for the functionality. Many thanks for your help.
(function() {
var Message;
Message = function({
text: text1,
message_side: message_side1
}) {
this.text = text1;
this.message_side = message_side1;
this.draw = () => {
var $message;
$message = $($('.message_template').clone().html());
$message.addClass(this.message_side).find('.text').html(this.text);
$('.messages').append($message);
return setTimeout(function() {
return $message.addClass('appeared');
}, 0);
};
return this;
};
$(function() {
var getMessageText, message_side, sendMessage;
message_side = 'right';
getMessageText = function() {
var $message_input;
$message_input = $('.message_input');
return $message_input.val();
};
sendMessage = function(text) {
var $messages, message;
if (text.trim() === '') {
return;
}
$('.message_input').val('');
$messages = $('.messages');
message_side = message_side === 'left' ? 'right' : 'left';
message = new Message({text, message_side});
message.draw();
return $messages.animate({
scrollTop: $messages.prop('scrollHeight')
}, 300);
};
$('.send_message').click(function(e) {
return sendMessage(getMessageText());
});
$('.message_input').keyup(function(e) {
if (e.which === 13) { // enter key
return sendMessage(getMessageText());
}
});
});
}).call(this);

<div class="message_template">

<p class="text"></p>

You can also add:
$(".left").css("color", "yellow");
$(".right").css("color", "blue");

$("li.message.left > div.text_wrapper > p").css('color', 'red');
$("li.message.right > div.text_wrapper > p").css('color', 'blue');

Using jQuery you can add inline style to an element
$(".left").attr("style","whatever");
$(".right").attr("style","whatever");

You can use the classList of every HTML component. Simply, select the DOM element with class left (or right) and use the add method to assign whatever class:
var elementLeft = $('.left')
elementLeft.classList.add('yourClass')
You can also use the methods remove to remove any class, or toggle to toggle some class..
elementLeft.classList.remove('yourClass')
elementLeft.classList.toggle('yourClass')
The Element.classList contains more examples. This solution works without jQuery or others javascript library, but use the standard API.

error in redirecting onmouseover to other elements

I want that the moment I move my mouse over the svg, the text will shift to the right, making it visible; however it is not working. What would be the problem?
HTML:
<div class="exitBox">
<span class="exitButton"><?php include "SVGs/sair.svg"; ?></span>
<span class="exit">SAIR</span>
</div>
CSS:
.exitBox{
display: inline;
position: fixed;
top: 20px;
left: 40px;
overflow: hidden;
}
.exitButton svg{
width: 20px;
color: black;
}
#exitA{
display: inline-block;
text-decoration: none;
color: black;
font-size: 30px;
letter-spacing: 2px;
font-family: Teko;
transform: translateX(-100px);
}
SCRIPT JS:
var exit = document.getElementById("exitA");
var exitB = document.getElementsByClassName("exitButton");
exitB.onmouseover = function exit(){
exit.style.transform = "translateX(100px)";
}

You use the same name for the function and the exit element.
You are moving it to 100px from -100px, which means 200px, this leads the text to go out of the screen
var exitB = document.getElementsByClassName("exitButton")[0];
exitB.onmouseenter = function exit(){
var exitA = document.getElementById("exitA");
exitA.style.transform = "translateX(0)";
}
.exitBox{
display: inline;
position: fixed;
top: 20px;
left: 40px;
overflow: hidden;
}
.exitButton svg{
width: 20px;
color: black;
}
#exitA{
display: inline-block;
text-decoration: none;
color: black;
font-size: 30px;
letter-spacing: 2px;
font-family: Teko;
transform: translateX(-100px);
}
<div class="exitBox">
<span class="exitButton"><div>hover</div></span>
<span class="exit">SAIR</span>
</div>

Toggle Switch to disable and enable Links

In the code below, I have coded a switch that disables and enables my links using CSS.
The problem is that my switch is not changing its appearance. It's doing its job (the JavaScript functionality is working), but the appearance isn't. I don't have much experience with
HTML Button:
<label class="switch" isValue="0">
<div class="slider round">
</div>
</label>
CSS:
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
transition: .4s;
}
input[type="checkbox"]:checked + input[type="hidden"] + .slider,
input[type="checkbox"]:checked + .slider {
background-color: #2196F3;
}
input[type="checkbox"]:focus + input[type="hidden"] + .slider,
input[type="checkbox"]:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input[type="checkbox"]:checked + input[type="hidden"] + .slider:before,
input[type="checkbox"]:checked + .slider:before {
transform: translateX(26px);
}
Rounded sliders
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
.dim.disabled {
pointer-events: none;
background-color: grey;
}
JavaScript:
$(document).on('click', '.switch', function () {
var v = $(".switch").attr("isValue");
if (v == 1) {
$(".switch").attr("isValue", "0");
$(".dim").removeClass("disabled");
}
else {
$(".switch").attr("isValue", "1");
$(".dim").addClass("disabled");
}
});
I know there is something wrong with this because it is of the input type checkbox.
Thank you for any help you can provide.

Okay, ignoring the proposed code that is too vague, here's how a jQuery class toggle works:
$(".switch").on('click', function () {
$(this)
.toggleClass('disabled')
.data('status', ($(this).hasClass("disabled")? '0':'1'));
console.clear();
console.log('data-status value is :', $(this).data('status') );
});
.switch > span {
display: block;
width: 68px;
height: 68px;
background-color: green;
border-radius: 34px;
}
.switch.disabled > span {
background-color: grey;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="switch" data-status="1"><span></span></div>

Using just CSS, incase you wanted to go that route. Figured it might be useful since you are saying the Javascript works but the appearance will not change.
Basic switch
/** Format Example Body **/
body {
margin: 0;
padding: 0;
background: #f0f0f0;
}
* {
box-sizing: border-box;
}
.container {
max-width: 500px;
margin: 0 auto;
background: #fff;
}
.components {
padding: 20px;
}
.components .content {
margin-bottom: 20px;
}
.default {
margin: 0 5px;
}
.switch {
display: inline-block;
}
.switch input {
display: none;
}
.switch small {
display: inline-block;
width: 100px;
height: 18px;
background: #3a3a3a;
border-radius: 5px;
position: relative;
cursor: pointer;
}
.switch small:after {
content: "No";
position: absolute;
color: #fff;
font-size: 11px;
font-weight: 600;
width: 100%;
text-align: right;
padding: 0 6px;
box-sizing: border-box;
line-height: 18px;
}
.switch small:before {
content: "";
position: absolute;
width: 12px;
height: 12px;
background: #fff;
border-radius: 50%;
top: 3px;
left: 3px;
transition: .3s;
box-shadow: -3px 0 3px rgba(0, 0, 0, 0.1);
}
.switch input:checked~small {
background: #3fc55c;
transition: .3s;
}
.switch input:checked~small:before {
transform: translate(25px, 0px);
transition: .3s;
}
.switch input:checked~small:after {
content: "Yes";
text-align: left;
}
<div class="container">
<div class="components">
<div class="content">
<label class="switch default">
<input type="checkbox">
<small></small>
</label>
</div>
</div>
</div>

I think you just need to have a specific name of a class for an enabled link or disabled link
style
.link_enabled {
/* style for enabled link */
}
.link_disabled {
/* style for disabled link */
}
script
$(document).on('click', '.switch', function () {
var v = $(".switch").attr("isValue");
if (v == 1) {
$(".switch").attr("isValue", "0");
$(".switch").removeClass("link_enabled").addClass("link_disabled");
$(".dim").removeClass("disabled");
}
else {
$(".switch").attr("isValue", "1");
$(".switch").removeClass("link_disabled").addClass("link_enabled");
$(".dim").addClass("disabled ");
}
});

For the record, please note that it is simpler in JS (es6).
And because the subject only mentions javascript (not jQuery) on tag list.
document.querySelector('.switch').onclick = function(e) {
this.dataset.status = this.classList.toggle('disabled')?'0':'1';
console.clear();
console.log('data-status value is :', this.dataset.status );
}
.switch>span {
display: block;
width: 68px;
height: 68px;
background-color: green;
border-radius: 34px;
}
.switch.disabled>span {
background-color: grey;
}
<div class="switch" data-status="1" ><span></span></div>

I attached my CSS and HTML code and i tried it's working but URL is opening in another tab. i need open the url in same tab please tell me the solution how to fix this.

In your code dropdown isn't ever made visible.
I think, you on click of "Notifications" you have to toggle(hide/show) dropdown by toggling(adding and removing) "active" class on Notifications tag.
Once your dropdown becomes visible. clicks should work as you desire.
Sample working code:
Notifications
<script>
function toggleDropdownVisibility(event) {
var notificationBell = event.target;
if (notificationBell.classList.contains('active')) {
notificationBell.classList.remove('active');
} else {
notificationBell.classList.add('active');
}
}
</script>
In addition to that please remove onclick="window.location.href('view-post.php')" as window.location.href is not a function instead it a property to which a url can be assigned. like window.location.href='view-post.php' . But you can completely remove this onclick as its not needed.

Your code looks fine here , except that I don't understand why you have opacity:0 and visibility:hidden on the .dropdown css class. These are making your control not accessible.
But once I remove these 2 properties in css worked for me (on last version of Chrome)
My advice:
For tags you can use this :
https://bootstrap-tagsinput.github.io/bootstrap-tagsinput/examples/. No need too much custom JS.

I have the solution for this, i tried that and it's working.
<div class="toparea-right">
<ul class="setting-area">
<li>
<i class="far fa-newspaper"></i>
<span class="notifi-count" id="displayNotiCount">00</span>
Notifications
<div class="dropdowns" id="MmailNoti">
<ul class="drops-menu">
<li>
<a href="view-post.php" onclick="window.location.href('view-post.php')" title="">
<div class="mesg-meta-notification">
<h6>Bruce Wayne</h6>
<span>is commented in your post!</span>
<i>0 min ago</i>
</div>
</a>
</li>
</ul>
</div>
</li>
</ul>
</div>
<script>
// When the user clicks on div, open the popup
function myFunction() {
var popup = document.getElementById("MmailNoti");
popup.classList.toggle("show");
}
</script>

Target closest icon to change it into another icon

I have a series of cards in the same page. Below is the example the example below where I have put for this example only 1 card (but there are many more).
I fail to use jquery 'closest' or 'siblings' or something similar to do the following: when a user click on a card it collapses and the javascript kicks in to show the content. I need at that moment to replace the "plus icon" by a "minus icon". (only on this specific card so not using at any point a id or class containing the number of the card '354' in the example below)
Jsfiddle Demo
The Javascript should target the icon but it does not change it when I click
If you have trouble making appear the content, do not worry, it's not the focus of the question. I just want to know how to target the icon and change into to glyphicon minus.

The ID is wrong collapseOne_354 while you are binding collapseOne
EDIT
I would reach the glyphicon with
var list = $('.cards-list')
$('li', list).click(function(e){
var card=$(this);
$(this).find(".glyphicon").toggleClass("glyphicon-minus").toggleClass("glyphicon-plus");
});
