So, I was given a task of creating a Custom Flipbook, where using images in div tags, I was successful in creating one. Users could turn pages using prev/next buttons or flipping through them by the corners like shown for other Flipbooks.
My concern is Displaying PageNumbers. Changing pages through the buttons, pages change dynamically but when flipping through turn.js the page number does not update.
I am providing the snippet of the code that I have used. Any kind of help and guidance is appreciated !!

I am making a google docs like app, and I want the user to be able to select the text, and then change the size to whatever they want. I tried to use variables but it didn't work so I am not sure what to do. Is there any way to allow the user to change the font size and if so how?
Here is the code for the app:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Editor</title>
<link rel="stylesheet" href="index.css" />
</head>
<body>
<button class="bold" onclick="document.execCommand('bold',false,null);">
𝗕
</button>
<button class="italic" onclick="document.execCommand('italic',false,null);">
𝘐
</button>
<button
class="underline"
onclick="document.execCommand('underline',false,null);"
>
U̲
</button>
<input
type="color"
class="color-picker"
id="colorPicker"
oninput="changeColorText(this.value);"
/>
<label>Select color</label>
<button id="highlight"><mark>Highlight</mark></button>
<fieldset class="userInput" contenteditable="true"></fieldset>
<script>
var boldBtn = document.querySelector(".bold");
var italicBtn = document.querySelector(".italic");
var underlineBtn = document.querySelector(".underline");
var colorPicker = document.querySelector(".color-picker");
var highlightBtn = document.querySelector("#highlight");
boldBtn.addEventListener("click", function () {
boldBtn.classList.toggle("inUse");
});
italicBtn.addEventListener("click", function () {
italicBtn.classList.toggle("inUse");
});
underlineBtn.addEventListener("click", function () {
underlineBtn.classList.toggle("inUse");
});
highlightBtn.addEventListener("click", function () {
highlightBtn.classList.toggle("inUse");
});
const changeColorText = (color) => {
document.execCommand("styleWithCSS", false, true);
document.execCommand("foreColor", false, color);
};
document
.getElementById("highlight")
.addEventListener("click", function () {
var range = window.getSelection().getRangeAt(0),
span = document.createElement("span");
span.className = "highlight";
span.appendChild(range.extractContents());
range.insertNode(span);
});
</script>
</body>
</html>
I think this is the output you want. Also, don't use document.execCommand, it has been deprecated
<!DOCTYPE html>

var boldBtn = document.querySelector(".bold");
var italicBtn = document.querySelector(".italic");
var underlineBtn = document.querySelector(".underline");
var colorPicker = document.querySelector(".color-picker");
var fontSize = document.querySelector("#fontSize");
var highlightBtn = document.querySelector("#highlight");
var userInput = document.querySelector('.userInput');
boldBtn.addEventListener("click", function () {
boldBtn.classList.toggle("inUse");
});
italicBtn.addEventListener("click", function () {
italicBtn.classList.toggle("inUse");
});
underlineBtn.addEventListener("click", function () {
underlineBtn.classList.toggle("inUse");
});
highlightBtn.addEventListener("click", function () {
highlightBtn.classList.toggle("inUse");
});
const changeColorText = (color) => {
document.execCommand("styleWithCSS", false, true);
document.execCommand("foreColor", false, color);
};
fontSize.addEventListener('input', updateValue);
function updateValue(e) {
userInput.style.fontSize = `${e.target.value}px`;
}
document
.getElementById("highlight")
.addEventListener("click", function () {
var range = window.getSelection().getRangeAt(0),
span = document.createElement("span");
span.className = "highlight";
span.appendChild(range.extractContents());
range.insertNode(span);
});
</script>
</body>
</html>
Add this to your HTML:
<button class="font-smaller">-</button>
<button class="font-bigger">+</button>
Add this to your JS:
const fontSmaller = document.querySelector(".font-smaller");
const fontBigger = document.querySelector(".font-bigger");
let fontSize = 15.5; // play with this number if needed
fontSmaller.addEventListener("click", () => {
document.querySelector(".userInput").style.fontSize = `${fontSize--}px`;
});
fontBigger.addEventListener("click", () => {
document.querySelector(".userInput").style.fontSize = `${fontSize++}px`;
});
Change as needed. This will change the size of the whole text.
You can implement it like this.
// Increase/descrease font size
$('#increasetext').click(function() {
curSize = parseInt($('#content').css('font-size')) + 2;
if (curSize <= 32)
$('#content').css('font-size', curSize);
});
$('#resettext').click(function() {
if (curSize != 18)
$('#content').css('font-size', 18);
});
$('#decreasetext').click(function() {
curSize = parseInt($('#content').css('font-size')) - 2;
if (curSize >= 14)
$('#content').css('font-size', curSize);
});

i am trying to create divs that are boxes and do the following on them
1) change the background color
2) make them look like a circle
3) create more boxes(divs)
each has a individual button to fire the events but the boxes wont show and the only the second button works,with the console.log and the console doesnt show any errors at all
here is the html code and style
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js" >
</script>
<script src="Query_script.js"></script>
<div class= "packages">

<style>
.packages{
border-color: black;
border-width: 5px;
height: 75 px;
width: 75 px;
}
</style>
</body>
</html>
and here is the js and query
let pack=document.getElementById("packages");
let rad= document.getElementById("R-border");
let Adder=document.getElementById("create");
let checker=true;
$(document).ready(function() {
$("#changer").click(function(){
console.log("clicked1");
if (checker==true){
$('.pack').css('background-color','red');
checker=false;
}
else{
$('.packa>div').css('background-color','white');
checker=true;
}
});
});
$(document).ready(function() {
$("#R-border").click(function(){
if(checker==true){
console.log("clicked2");
$('.pack').css("border-radius","50%");
checker=false;
}
else{
$('.pack').css("border-radius");
}
});
});
$(document).ready(function() {
$("#Adder").click(function(){
console.log("clicked3");
$('.pack').append("<div>");
});
});
Maintain CSS selector names properly
I have done some modifications to HTML and javascript. Try this... It's working properly.
let pack = document.getElementById("packages");
let rad = document.getElementById("R-border");
let Adder = document.getElementById("create");
let checker = true;
$(document).ready(function () {
$("#change").click(function () {
console.log("clicked1");
if (checker == true) {
$('.packages').css('background-color', 'red');
checker = false;
} else {
$('.packages > div').css('background-color', 'white');
checker = true;
}
});
});
$(document).ready(function () {
$("#R-border").click(function () {
console.log("clicked2");
if (checker == true) {
$('.packages').css("border-radius", "50%");
checker = false;
} else {
$('.packages').css("border-radius");
}
});
});
$(document).ready(function () {
$("#create").click(function () {
console.log("clicked3");
$('.packages').append("<div>");
});
});

Hello I have a number animation on my web page and I dont want the animation to start until it is in the middle of the web page. I tried to google onscroll and other options but I could not get this to work properly.
I prefer for the animation not to start until the visitor has scrolled down to 472px. As of right now as soon as the web page loads the number animation starts automatically. Any help I would really appreciate it.
// 472 px - Starts Yellow Counter Section
const counters = document.querySelectorAll('.counter');
const speed = 200; // The lower the slower
counters.forEach(counter => {
const updateCount = () => {
const target = +counter.getAttribute('data-target');
const count = +counter.innerText;
// Lower inc to slow and higher to slow
const inc = target / speed;
// console.log(inc);
// console.log(count);
// Check if target is reached
if (count < target) {
// Add inc to count and output in counter
counter.innerText = count + inc;
// Call function every ms
setTimeout(updateCount, 1);
} else {
counter.innerText = target;
}
};
updateCount();
});

wesbos has great video on this https://www.youtube.com/watch?v=uzRsENVD3W8&list=PLu8EoSxDXHP6CGK4YVJhL_VWetA865GOH&index=14&t=0s
Basically what you need to do is listen for scroll and check where user currently is compared to desired place in px
you can check code here and adjust it to your needs https://github.com/wesbos/JavaScript30/blob/master/13%20-%20Slide%20in%20on%20Scroll/index-FINISHED.html
Try getBoundingClientRect(). document.querySelector( 'some element' ).getBoundingClientRect() will give you the properties of the specific element
for Example if you want to start an animation when an element is visible to user on his screen ( in the visible viewport ), you can use this to call the function and start the animation
let calledStatus = 0; // some flag variable to remember if function is called
window.onscroll = function(){
element = document.querySelector( '.some element' );
clientRect = element.getBoundingClientRect();
if( clientRect.top < window.innerHeight && clientRect.top > ( clientRect.height * -1) && calledStatus == 0){
//call your function or do other stuff
console.log('called' )
calledStatus = 1;
}
}
By using jquery , first add this reference script above your js code or referenece script
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></scrip>
....
</head>
if you want the code to launch specifically after 472 px:
js
$(document).ready(function () {
Let initialScroll = true;
//you can decrease or increase 472 depending on where exactly
//you want your function to be called
$(document).scroll(function () {
if (($(document).scrollTop() > 472)&& initialScroll) {
//call your function here
console.log( "reached 472")
InitialScroll=false;
}
});
});
if you want your function to start after reaching the middle
of the document
you place a div where the middle of the html code is :
html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
...
<div id="middle"></div>
...
</body>
</html>
js
$(document).ready(function () {
Let initialScroll=true
$(document).scroll(function () {
if (($(document).scrollTop() >=$('#middle').position().top)&&initialScroll) {
//call your function here
console.log( "reached middle")
InitialScroll=false;
}
});
});
There is a native javascript API for "listetning" where the user currently is on the page called Intersection Observer. Basically you set a callback which should execute once the desired content scrolls into view.
It's used for all those fancy page animations where cards appear once you start scrolling to the bottom of the page since it's far more efficient than listening on the scroll event.
Kevin Powell did a great video about this topic.
Hope it helps!
Here's a code copy pasted, but it should give you a clue on how it should work:
document.addEventListener("DOMContentLoaded", function() {
let lazyImages = [].slice.call(document.querySelectorAll("img.lazy"));
let active = false;
const lazyLoad = function() {
if (active === false) {
active = true;
setTimeout(function() {
lazyImages.forEach(function(lazyImage) {
if ((lazyImage.getBoundingClientRect().top <= window.innerHeight && lazyImage.getBoundingClientRect().bottom >= 0) && getComputedStyle(lazyImage).display !== "none") {
lazyImage.src = lazyImage.dataset.src;
lazyImage.srcset = lazyImage.dataset.srcset;
lazyImage.classList.remove("lazy");
lazyImages = lazyImages.filter(function(image) {
return image !== lazyImage;
});
if (lazyImages.length === 0) {
document.removeEventListener("scroll", lazyLoad);
window.removeEventListener("resize", lazyLoad);
window.removeEventListener("orientationchange", lazyLoad);
}
}
});
active = false;
}, 200);
}
};
document.addEventListener("scroll", lazyLoad);
window.addEventListener("resize", lazyLoad);
window.addEventListener("orientationchange", lazyLoad);
});
I wanted to create an effect where the whole body gets blurred or dimmed and only a particular list item appears clear. However when I set the z-index to the list item, it doesn't work. And when I set the z-index of the whole un-ordered list, it works but the all the list items appear clear (which I don't want).
Let me show you my html code:
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Ashish Toppo</title>
<link href="https://fonts.googleapis.com/css?family=Oxanium&display=swap" rel="stylesheet">
<link rel="stylesheet" href="css/style.css">
</head>
<body >
<!-- the html for the top bar starts here -->
<div class="top_bar" id="topBar">
<div class="logo_name" id="logoName">Ashish Toppo</div>
<ul class="menu">
<li class="menu_items currently_active_menuItem" id="home">home</li>
<li class="menu_items" id="about">about</li>
<li class="menu_items" id="education">education</li>
</ul>
</div>
<!-- the html for the top bar ends here -->
<!-- the html for the intro starts here -->
<div class="intro" id="intro">
<div class="profile_pic" id="profilePic">
<img id="profileImg" src="images/ashish-toppo-green.jpg" width="100%" height="100%" alt="a picture of mine">
</div>
<div class="intro_box" id="introBox">
<!-- some introduction text here -->
<center id="aboutPointer">To know more about me, go to the about section!</center>
</div>
</div>
<!-- the html for the intro ends here -->
<script src="js/uiversal.js"></script>
<script src="js/index.js"></script>
</body>
</html>
Now, the Universal javaScript file:
/* this is a reusable js file universal to all web pages */
/* Ashish Toppo */
"use strict";
function get(id_or_class){
var obj = {
element: ( document.getElementById(id_or_class) ) ? document.getElementById(id_or_class) :
( document.getElementsByClassName(id_or_class) ) ? document.getElementsByClassName(id_or_class) :
( document.querySelector(id_or_class) ) ? document.querySelector(id_or_class) :
console.error("The provided HTML element could not be found"),
html: () => { return obj.element; },
changeText: (text) => { obj.html().innerHTML = text; },
appendText: (text) => {
let appendOn = obj.html().innerHTML;
obj.html().innerHTML = appendOn + text;
},
previousDisplayMode: "block",
hide: () => {
obj.previousDisplayMode = obj.html().style.display;
obj.html().style.display = "none";
},
show: () => {
obj.html().style.display = obj.previousDisplayMode;
},
on: (event, callBack) => {
obj.html().addEventListener(event, callBack);
},
previousZIndex: 1,
focusOn: () => {
let blur = document.createElement("div");
blur.className = "theDivThatBlurs";
blur.style.width ="100vw";
blur.style.height ="100vh";
blur.style.display ="block";
blur.style.position ="fixed";
blur.style.top ="0";
blur.style.left ="0";
blur.style.zIndex ="9";
blur.style.backgroundColor ="rgba(0, 0, 0, 0.9)";
blur.innerHTML = "";
document.body.appendChild(blur);
obj.html().style.zIndex = "100";
}
}
return obj;
}
and the index.js file was as followed:
/* my css wasn't working as i wanted, so i had to fix it using js */
"use strict";
(function(d){
const active = d.getElementsByClassName("currently_active_menuItem");
active[0].style.textDecoration = "none";
})(document);
var about = get("about");
var aboutPointer = get("aboutPointer");
aboutPointer.on("click", function(){
console.log("the about pointer has been clicked");
focus(about);
});
function focus(theElement){
console.log("the focus is working");
theElement.focusOn();
}
You can use the box-shadow property to achieve the dimming effect. Quick and easy :)
Just toggle a class programmatically and it should work for any element you have.
Code
function focusAndDim() {
document.getElementById("maindiv").classList.toggle("visible");
// if you want to get more fancy ;)
document.getElementsByTagName("body")[0].classList.toggle("blur");
}
.visible {
box-shadow: 0 0 0 10000px #ccc;
/* this code below make everything else hidden */
/* box-shadow: 0 0 0 10000px #fff; */
position: relative;

I need a script to change the iframes src every certain amount of seconds. The time between the change is different between each one.
Example:
Page Loads
Google.com is loaded.
15 seconds later
Yahoo.com is loaded.
37 seconds later
Ask.com is loaded.
12 seconds later
Dogpile.com is loaded.
and so on and so forth.
I've tried that:

The way you are using setInterval and setTimeout is not properly
handled, as it creates a timer id to schedule execution. 0
A much more efficient way is to use the Promises async library, which is displayed below. 1
For websites that won't work, they are using a response header that won't allow their pages to be framed. You can work around this with some back-end program, where the server loads the web files then forwards them. 2
