There are several approaches. And there is no real right or wrong here either.
The approach has to fit your application. If you always try to keep the approach somewhat abstract, there is nothing fundamentally wrong with it.
In the example below, I have taken the linked modal example from the comment
below your question and adapted the following.
added a data object in which I manage the corresponding contents of the modal.Here you can also use an API call against an interface.
I have assigned an EventListener to all buttons.
The parts that are variable in the modal are exchanged with the corresponding content when clicked.
Done!
const modalData = [
{id: 1, title: "Title One", content: "bla"},
{id: 2, title: "Title Two", content: "bla blu"},
];
// Get the modal
var modal = document.getElementById("myModal");
// Get the button that opens the modal
var btns = document.querySelectorAll(".myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks the button, open the modal
btns.forEach(b => {
b.addEventListener('click', (e) => {
modal.style.display = "block";
const dataId = e.target.getAttribute("data-id")
const data = modalData.filter(m => m.id == dataId);
const modalTitle = document.querySelector("#myModal .title");
const modalContent = document.querySelector("#myModal .content");
modalTitle.innerHTML = data[0].title;
modalContent.innerHTML = data[0].content;
})
});
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
body {font-family: Arial, Helvetica, sans-serif;}

I just want to share my code here where I got the Idea on W3schools. I already search of the same topic, but it didn't solve the problem of my Code.
/* The Modal (background) MY CSS CODE*/
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
/* The Modal1 (background) */
.modal1 {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
And heres the Javascript Code
<!-- Javascript -->
<script>
// Get the modal
var modal = document.getElementByclass("myModal");
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
<script>
// Get the modal1
var modal = document.getElementByIclass("myModal1");
// Get the button that opens the modal
var btn = document.getElementById("myBtn1");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close1")[0];
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
And Lastly, the HTML Code
<!-- Trigger/Open The Modal -->
<button id="myBtn">Apply Now</button>
<!-- The Modal -->
<div class="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the Modal..</p>
</div>
</div>
<!-- Trigger/Open The Modal1 -->
<button id="myBtn1">Apply Now</button>
<!-- The Modal -->
<div class="myModal1" class="modal1">
<!-- Modal content -->
<div class="modal-content">
<span class="close1">×</span>
<p>Some text in the Modalsssssss..</p>
</div>
</div>
I've been kinda stuck with this for a long time. Any opinion or suggestions will be greatly appreciated.
**** UPDATE**
Read your comment and I agree, this is pretty "hacky" and I personally would almost never do this. So I want to show you a solution which is closer to what I would do on a production site. A quick overview:
The code for the actual modal is good, so we can use that.
What I think is "hacky" here is the way we get the data to feed to the modal. Storing data in HTML elements is not terrible, but there are way better ways to do this.
A good way to store this kind of data (strings, numbers, etc.) is with JSON.
We can include the JSON data in the document itself, or we can use AJAX to store it in a different location. Could be a file on the server, or maybe a database somewhere.
More info on $.getJSON() method.
/* Same code from previous example. New code marked with comments */
$("body").on("click", ".toggle-modal", function() {
if ($(".modal").is(":visible")) {
$(".modal").fadeOut("fast", function() {
$(this).remove()
});
} else {
/* Get the data ID from the html element */
const data_id = $(this).data("modal-text");
/* Get JSON data from file on server (simplified)
Replace the url with the path to your JSON file on the server. */
$.getJSON("https://httpbin.org/json", function(response) { // <-- Callback function
/* This is the "callback" function from the "getJSON" method
This fires when the AJAX request has been completed
This function has access to the AJAX response variable which contains the returned data */
/* Light validation here just checks if the response is json */
if (typeof response == 'object') {
/* For kicks let's check out the response */
console.log(response);
/* The response is obviously not our data. Next variable emulates correct response */
response = {
primary_modal: "The message for the primary modal",
secondary_modal: "The message for the secondary modal"
}
/* Get the correct message from the response.
Use the value from the data attribute as the key to find our data in the json structure */
const msg = response[data_id];
/* Launch the modal */
const modal = $("<div />", {
"class": "modal"
}).append(
$("<div />", {
"class": "modal-overlay toggle-modal"
}),
$("<div />", {
"class": "modal-container"

Here is a really easy way to re-purpose a modal template for different content using jQuery. Basically you store the message right in the button's data attribute, then just append that content to the dynamically generated modal.
/* Listen for the click event on the button */
$("body").on("click", ".toggle-modal", function() {
/* Check if modal is open */
if ($(".modal").is(":visible")) {
/* if modal is already visible close it out */
$(".modal").fadeOut("fast", function() {
$(this).remove()
});
} else {
/* Get message from button */
const msg = $(this).data("modal-text");
/* dynamically create modal elements */
const modal = $("<div />", {
"class": "modal"
}).append(
$("<div />", {
"class": "modal-overlay toggle-modal"
}),
$("<div />", {
"class": "modal-container"
}).append(
$("<div />", {
"class": "modal-close toggle-modal"
}),
$("<div />", {
"class": "modal-content"
}).text(msg) /* Append text to modal */
)
).appendTo("body") /* Append modal to body */
.fadeIn("fast") /* Fade in modal */
.css("display", "flex") /* Flexbox to center content */
}
})
body,
html {
margin: 0;
padding: 0;

I had a multi-page website in that there are four links on the navbar. Out of four links two links redirects to other new pages.

if ($(this).position().top <= scrollDistance) {
$('.navigation a.active').removeClass('active');
$('.navigation a').eq(i).addClass('active');
}
});
}).scroll()
For more custom assignments of when what should happen, there is a (very old, but still working) jQuery plugin. See:
Github: jquery.inview
Tutorial: Element 'in view' Event Plugin
Usage:
$('#mySection1').on('inview', function(event, isInView) {
if (isInView) {
$('#myNavOption1').addClass('active');
} else {
$('#myNavOption1').removeClass('active');
}
});
What you are looking for is a scrollspy:
Scrollspy · Bootstrap
or if that is not suitable for you just google "scrollspy" and find other frameworks that may fit you more.

I click each tab and entered some values in input field in first time. While clicking the second time the each tab, the input field has the entered values.Now I want to clear the input fields or reload/refresh the page while clicking the tabs further times and want to set auto focus the input field. Guide me for my situation. Thanks in advance.
Try to reset the value
function reset(Name) {
document.getElementById("txt"+Name).value = '';
}
function openTab(evt, Name) {
reset(Name);
// your code
}
I created 2 buttons on HTML, and by pressing a button, it will open a modal screen. This eaxmple is with 2 buttons, but my aim is that a page could have multiple buttons.
When pressing the X it closes the modal screen.
But, if you press outside the modal area, it should close it as well.
This does not work for both buttons.
Any help would be appreciated, or if you know of a easier/better way to work with modal screens. :-)

You have two window.onclick = function(event) Second one overrides first one.
So you really should have only one window.onclick handler:

or is there any different ways that you would recommend i do this?
<?php
session_start();
include 'loginlogoutregister.php';
//connecting to database
$link = mysqli_connect("localhost","root","","authentication");
if(isset($_POST['Login_Btn'])){
login($link);
}
if(isset($_POST['Register_Btn'])){

.closeLR:hover,
.closeLR:focus {

moving the script to the bottom of the body tag solved this issue
Move your script <script>
var modal = document.getElementById('PopUpLR');
var btn = document.getElementById("myBtn");
var span = document.getElementsByClassName("closeLR")[0];
btn.onclick = function() {
modal.style.display = "block";
}
span.onclick = function() {
modal.style.display = "none";
}
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
under your HTML so the button knows what its sending to!
