I would like to know how could I make my div that contains text fade in from bottom to top when scrolling down the page? i will be grateful for your help. Here is my Code:
var $text = $('.textBlock');
$(window).on('scroll', function(event, element) {
$text.each(function(event, element) {
if ($(this).visible()) {
$(this).children('p').stop().fadeIn();
} else {
$(this).siblings('.textBlock p').stop().fadeOut();
}
});
});
.textBlock {
text-align: center;
width: 100%;
height: 118px;
float: left;
display: block;
}
.textBlock p {
font-size: 24px;
padding: 30px 0;
line-height: 25px;
letter-spacing: 0.1em;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="blockOne" class="textBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
<div id="blockTwo" class="textBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
<div id="blockThree" class="textBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
You need to use a timer function for this. Check this out:
$(function () {
$(".textBlock").hide();
$("#blockOne").show();
$(window).scroll(function () {
numTextBlocks = $(".textBlock").length;
$(".textBlock:visible").fadeOut(400, function () {
console.log(".textBlock:nth-child(" + ($(window).scrollTop() * 10) % numTextBlocks + ")");
$(".textBlock:nth-child(" + ($(window).scrollTop() * 10) % numTextBlocks + ")").fadeIn(400);
});
});
});
html, body {
height: 150%;
}
.textBlock {
position: fixed;
text-align: center;
width: 100%;
height: 118px;
}
.textBlock p {
font-size: 24px;
padding: 30px 0;
line-height: 25px;
letter-spacing: 0.1em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="blockOne" class="textBlock">
<p>One Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
<div id="blockTwo" class="textBlock">
<p>Two Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
<div id="blockThree" class="textBlock">
<p>Three Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
This is what I used:
$(document).on("mousewheel", function () {
$(".textBlock:not(:visible)").first().fadeIn("slow")
});
Here is the JSFiddle demo
Let me know if this code works with you.
Fiddle
$(window).on("load",function() {
function fade() {
$('.fade').each(function() {
/* Check the location of each desired element */
var objectBottom = $(this).offset().top + $(this).outerHeight();
var windowBottom = $(window).scrollTop() + $(window).innerHeight();
/* If the object is completely visible in the window, fade it in */
if (objectBottom < windowBottom) { //object comes into view (scrolling down)
if ($(this).css('opacity')==0) {$(this).fadeTo(500,1);}
} else { //object goes out of view (scrolling up)
if ($(this).css('opacity')==1) {$(this).fadeTo(500,0);}
}
});
}
fade(); //Fade in completely visible elements during page-load
$(window).scroll(function() {fade();}); //Fade in elements during scroll
});

I made a scroll to top button that appears when the user scrolls down 25px from the top of the document (otherwise it's not visible) thanks to JavaScript following a tutorial because I still don't know anything about this programming language.
However, I would like it to be visible only on desktop websites and not also on mobile.
I tried using media queries but they don't work since JavaScript has control over the visibility of the button.
What function can I integrate to manage everything with JS?
Here is the code I'm using.
let myButton = document.getElementById("to-top-container");
window.onscroll = function() {
scrollFunction()
};
function scrollFunction() {
if (document.body.scrollTop > 25 || document.documentElement.scrollTop > 25) {
myButton.style.display = "block";
} else {
myButton.style.display = "none";
}
}
#to-top-container {
position: fixed;
bottom: 30px;
right: 3px;
}
.to-top-button {
background-color: #263238;
min-height: 40px;
min-width: 40px;
border-radius: 20px;
text-decoration: none;
display: flex;
justify-content: center;
align-items: center;
box-shadow: 2px 4px 5px rgb(0 0 0 / 30%);
/* animation: Up 2.3s infinite; */
}
#to-top-container .lni {
font-size: 14px;
font-weight: 900;
color: white;
}
<div id="to-top-container">
<a href="#body-container" title="Torna su" class="to-top-button">
<i class="lni lni-chevron-up"></i>
</a>
</div>
There is a JS way to detect if a media query is matched: this is done by using window.matchMedia(). Then it is a matter of adding the appropriate media query to matchMedia() function, and then checking the .matches property in your if block:
let myButton = document.getElementById("to-top-container");
window.onscroll = function() {
scrollFunction()
};
function scrollFunction() {
const matchesMediaQuery = window.matchMedia('(min-width: 600px)');
if (matchesMediaQuery.matches && (document.body.scrollTop > 25 || document.documentElement.scrollTop > 25)) {
myButton.style.display = "block";
} else {
myButton.style.display = "none";
}
}
scrollFunction();
#to-top-container {
position: fixed;
bottom: 30px;
right: 3px;
}
.to-top-button {
background-color: #263238;
min-height: 40px;
min-width: 40px;
border-radius: 20px;
text-decoration: none;
display: flex;
justify-content: center;
align-items: center;
box-shadow: 2px 4px 5px rgb(0 0 0 / 30%);
/* animation: Up 2.3s infinite; */
}
#to-top-container .lni {
font-size: 14px;
font-weight: 900;
color: white;
}
<div id="to-top-container">
<a href="#body-container" title="Torna su" class="to-top-button">
<i class="lni lni-chevron-up"></i>
</a>

Just Add this css in your css file or if you are using bootstrap then add bootstrap media query to disable display in mobile
#media only screen and (max-width: 600px) {
#to-top-container {
display: none;
}
}
You don't need javaScript to do it, you should have used the "a" tag to jump to other pages. But the "a" tag can also jump to an element on the same page.
As defined in the HTML specification, you can use href="#top" or href="#" to link to the top of the current page.
The #media query is set to max-width: 600px - adjust the max-width to fit your needs.
html {
scroll-behavior:smooth;
}
body {
position: relative;
}
.section {
height: 100vh;
background: #dedede;
margin-bottom: 20px;
font-size: 100px;
}
.scroll-container {
position: absolute;
top: 0;
right:0;
height: 100%;
}
.scroll-container:before {

.scroll-container a {

I've made a simple preloader but I want it to disappear after the page loaded plus two seconds.
How do I do it?
var loader = document.getElementById("Preloader");
window.addEventListener("load", function(){
loader.style.display = "none";
})
#Preloader {
background: #000 url(https://gph.is/g/46ql32M) no-repeat center center;
height: 100vh;
width: 100%;
position: fixed;
z-index: 99;
}
<div id="Preloader"></dv>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
You can use the setTimeout method to delay the update of the display property:
var loader = document.getElementById("Preloader");
window.addEventListener("load", function() {
window.setTimeout(() => {
loader.style.display = "none";
}, 2000)
})
#Preloader {
background: #000 url(https://gph.is/g/46ql32M) no-repeat center center;
height: 100vh;
width: 100%;
position: fixed;
z-index: 99;
}
<div id="Preloader"></div>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
PS: https://gph.is/g/46ql32M is not a direct link to the preloader image

My issue is that releasing in the new position never happens. I even tried to use this example but it did not work for me:

I'm trying to make a simple game where
you start with 9 circles
when you click on a circle with a thicker border it's going to increment a score and cause new circles to be drawn randomly.
I've already worked on counting stuff but I have a problem, because wherever you click (I mean whatever div) it sums up points. I don't have an idea about how to deactivate div's which do not have a thicker border.
Please tell if this is a good programming approach.

Thanks a lot for any hints one more time!
You can store the current bordered div number in a variable, and each time the click function is called, you can check if the same div number triggered this function call.
Here is your modified code that does this:
window.onload = start;
function start() {
var div_value = "";
for (i = 0; i < 9; i++) {
var element = "div_number" + i;
div_value = div_value + '<div class="point" id="' + element + '" onclick="c(' + i + ')"> Klik </div>';
if ((i + 1) % 3 == 0) {
div_value = div_value + '<div style="clear:both;"> </div>';
}
}
document.getElementsByClassName("points")[0].innerHTML = div_value;
esthetic();
random_show();
}
currDiv = 0;
// IT SHOWS 1 RANDOM DIV TO START THE GAME
function random_show() {
var a = Math.floor((Math.random() * 8));
currDiv = a; // assign current bordered div
var x = document.getElementById("div_number" + a).style.border = "10px dotted";
}
var liczby = [];
// IT DROWN LOTS AND COUNT THE SCORE
function c(i) {
if (parseInt(i) == currDiv) { // check if the current div clicked is the bordered div
var a = Math.floor((Math.random() * 8));
this.i = a;
var z = document.getElementById("div_number" + i);
var y = document.getElementById("div_number" + a);
currDiv = a; // change it to the current bordered div
if (y.style.border = "10px dotted") {
z.style.border = "5px dotted";
liczby.push(i);
} else {
y.style.border = "8px solid";
}
var x = document.getElementById("zliczenie").innerHTML = liczby.length;
}
}
// IT GIVES EVERY DIV INITIAL style.border
function esthetic() {
var x = document.getElementsByClassName("point");
for (i = 0; i < 9; i++) {
x[i].style.border = "5px dotted";

Hope it helps!
It is always good practice to keep the styling in .css file and html tags in .html file and the code in .js file.
Also for checking if a particular style is there on an element, you should just check if the element has a particular class in its classlist. Refer: https://developer.mozilla.org/en/docs/Web/API/Element/classList
Create new classes in your .css as:
.boldCircle {
border: 10px dotted;
}
And in your code just do:
if(y.classlist.contains("boldCircle")) {
// Do what you want
}
Another thing that I would like to point out is the equality in if condition. You should use '==' instead of '='. '=' is assignment operator and evaluates to true always.
if (y.style.border == "10px dotted") {
// Do what you want
}
Building on #DeepakKumar recommendation, I would also think about using a class to flag an element as the active target. Your click event handler can then check for it and increment points/manage your array as needed.
I also simplified the code a bit to better format it for this sandbox.
// =====================
// Initialize the game
// =====================
function start() {
var divTemplate = '<div id="%1%" class="point" data-index="%2%" onclick="c(event)"> Klik </div>';
var clearTemplate = '<div style="clear:both;"> </div>';
var elPoints = document.getElementsByClassName("points")[0];
var div_value = "";
for (i = 0; i < 9; i++) {
div_value += divTemplate
.replace("%1%", "div_number" + i)
.replace("%2%", i);
if ((i + 1) % 3 == 0) { div_value += clearTemplate; }
}
elPoints.innerHTML = div_value;
liczby = [];
random_show();
}
// =====================
// =====================
// Set one div as the target
// =====================
function random_show() {
var a = Math.floor((Math.random() * 8));
var elCurrentTarget = document.querySelector(".point.target");
var elNewTarget = document.getElementById("div_number" + a);
if (elCurrentTarget) { elCurrentTarget.classList.remove("target"); }
elNewTarget.classList.add("target");
}
// =====================
// =====================
// If the target div was clicked increment the score
// reset the board.
// =====================
function c(event) {
var elTarget = event.target;
var elScore = document.getElementById("zliczenie");
if (elTarget.classList.contains("target")) {
liczby.push(elTarget.getAttribute("data-index"));
elScore.innerHTML = liczby.length;
}
random_show();
}

The following code means "score + 1 if you clicked the thick circle, score - 1 otherwise" :
score += i == winning ? +1 : -1;
See conditional operator for details.

hi there i'm trying to show a hidden div when scrolling down from the top of the browser page, like the Accordion function. What i'm using here is this Code:
HTML:-
// Visible DIV
<div class="firstBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
// Hiddden DIV
<div class="textBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
// Visible DIV
<div class="secondBlock">
<p>Lorem ipsum dolor sit Amet, consectetuer adipiscing.</p>
</div>
CSS:-
.textBlock {
text-align: center;
height: 104px;
width: 100%;
float: left;
display: none;
}
.textBlock p {
font-size: 16px;
font-family: arial,helvetica,sans-serif;
padding: 10% 5%;
line-height: 20px;
}
jQuery:-
$(document).ready(function(){
$(window).bind("scroll", function() {
if ($(this).scrollTop() > 600) {
$(".textBlock").fadeIn();
} else {
$(".textBlock").stop().fadeOut();
}
});
});
but it needs some modification in order to work like Accordion-Function.
If you want the accordion effect you should use the slideDown and slideUp functions (docs here), like so:
