How to target and display error message with data-error in JavaScript

I'de like to validate a form with data propriety data-error and data-error-visible. I want to display the error message only with JS and don't use anymore HTML codes to do it.
The current code I use is below and I left only the first input :
/******
*
FORM VALIDATION
*
******/
// DOM
const formData = document.querySelectorAll(".formData");
const form = document.getElementById("form");
const firstName = document.getElementById("firstName");
const lastName = document.getElementById("lastName");
const email = document.getElementById("email");
const birthdate = document.getElementById("birthdate");
const quantity = document.getElementById("quantity");
const tournament = document.getElementsByName("location");
const checkbox = document.getElementsByName("checkbox");
// form preventDefault + checkInputs function
form.addEventListener('submit', e => {
e.preventDefault();
});
/***********
*
DATA-ATTRIBUTE
*
************/
// set error message to "true"
const displayErrorMsg = (element, message) => {
const formData = element
formData.setAttribute("data-error", message)
formData.setAttribute("data-error-visible", true)
}
// Function for remove one error msg
const removeErrorMsg = (element) => {
const formData = element
formData.removeAttribute('data-error')
formData.removeAttribute('data-error-visible')
}
/***********
*
* VALIDATION FUNCTION
*
************/
function validate(formData) {
let isFormValid = true;
// Regex
const nameRegex = /[a-zA-Z]+/i;
// First name
if (firstName.value.match(nameRegex) || firstName.value.length < 2) {
isFormValid = false;
displayErrorMsg(firstName);
} else {
removeErrorMsg(firstName);
}
}

Onclick Function in Dropdown Menu not working

I'm a newbie and practicing dropdown menu using the following Youtube video https://www.youtube.com/watch?v=uFIl4BvYne0. Everything is working except the onclick function.
Can anyone point out where I'm going wrong?
function show(anything) {
document.querySelector('.textBox').value =
anything;
}
let dropdown = document.querySelector('.dropdown');
dropdown.onclick = function() {
dropdown.classList.toggle('active');

I have tried some fixes but couldn't find out the problem.
Note: I'm pretty new in this field.

You need to add addEventListener in order to append an action:
function show(anything) {
document.querySelector('.textBox').value =
anything;
}
let dropdown = document.querySelector('.dropdown');
dropdown.addEventListener('click', function(event) { // add click function
dropdown.classList.toggle('active'); // i don't know what class you want to change so i changed the background to a class to demonstrate the click
});

Aligning a chat bubble content to the right

I have a bootstrap card that is adding chat bubbles to a list group. I want to align the content to the right so the bubble isn't just in the middle. I tried using align=right and wrapping that div tag in:
$("#messages").append($("<div align=right><div class=bubble-r><li></div></div><br />").text(msg));
but that didn't work. What am I missing?
$("#messages").append(
$("<div class=bubble-r><li></div><br />").text(msg)
);
} else {
$("#messages").append(
$("<div class=bubble><li></div> <br />").text(msg)
);
}
});
}
render() {
return (
<ul id="messages">
<div />

);

How do I close custom popover when click outside?

I'm developing a Cordova app. For that I'm using Vue.js and jQuery for bindings and script and I'm developing UI on my own. I could do page transitions and animations for most of the UI like, Radio buttons and check boxes etc. But I could not be able to develop a custom popover. I have tried following code.
Vue.directive('popover', {
bind: function(el, bindings, vnode) {
$(el).click(function() {
var pageEl = $(this).closest('.ui-page');
pageEl.find('.drawer').toggleClass('active');
$(el).closest('.ui-page').click(function(e) {
// $('.drawer', this).removeClass('active');
});
});
}
})
var pageInstace = new Vue({
el: '#popover-page',
data: {
options: [1, 2, 3, 4, 5]
}
})

This works fine for toggling popover on button click. I tried so much. But I could not hide the popover when click on outside of the popover.
How can I hide popover when clicking out side of it?

Please try this. I have added jQuery
$('body').click(function(e) {
if (!$(e.target).closest('.drawer').length){
$(".drawer").removeClass("active");
}
});
$('body').click(function(e) {
if (!$(e.target).closest('.drawer').length){
$(".drawer").removeClass("active");
}
});
Vue.directive('popover', {
bind: function(el, bindings, vnode) {
$(el).click(function(e) {
e.stopPropagation();
var pageEl = $(this).closest('.ui-page');
pageEl.find('.drawer').toggleClass('active');
$(el).closest('.ui-page').click(function(e) {
// $('.drawer', this).removeClass('active');
});
});
}
})

How to move scrollbar in a jquery-jscrollpane to textarea cursor position

I try to implement in jsfiddle. When textarea expand scrollbar not move to textarea cursor.
JavaScript:
function addJScrollPaneTo($container) {
// use jScrollPane jquery plugin
$container.jScrollPane({
verticalGutter: 1,
stickToBottom: true,
enableKeyboardNavigation : false,
autoReinitialise: true
});
}
function appendTextareaTo($container) {
var $textarea = $("<textarea />");
// set textarea attribute
$textarea.css({'border': 'medium none'});
$textarea.width($container.width());
// use TextAreaExpander jquery plugin
$textarea.TextAreaExpander($container.height()-1);
$container.append($textarea);
}
// for padding with elem
function appendContainer(elem) {
var $container = $("<div />");
// set container attribute
$container.width($(elem).width());
$container.height($(elem).height());
$(elem).append($container);
appendTextareaTo($container);
addJScrollPaneTo($container);
}
function setCSS(elem) {
$(elem).css({
'border': 'thin solid #CCCCCC',
'padding': '1px'
});
}
setCSS("#test");
appendContainer("#test");
