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">
<div></div>
<div></div>
</div>

<button id = "create">Add an extra box </button> <br>
<style>
.packages{
border-color: black;
border-width: 5px;

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 everybody I have this code that I have made alone.
function appearafter() {
document.getElementById("buttonappear").style.display = "block";
document.getElementById("button").style.display = "block";
document.getElementById("hinzufuegen").style.display = "none";
function myFunction() {
var itm = document.getElementById("myList2").lastChild;
var cln = itm.cloneNode(true);
document.getElementById("myList1").appendChild(cln);
}
function allFunction() {
myFunction();
appearafter();
}
#button {
display: none;
}
#buttonappear {
display: none;
}
#test {
width: 300px;
height: 300px;
background-color: red;
}
<!DOCTYPE html>
<html>
<body>
<button id="hinzufuegen" onclick="allFunction()">ADD</button>
<div id="myList1">
<button id="button" onclick="">DELETE</button>
<div id="myList2">
<div id="test">
</div>
</div>
</div>
<button onclick="allFunction()" id="buttonappear">ADD</button>
</body>
</html>
What I want to make is that the red square whenever you are clicking on the ADD button it will be a clone and when you click on the DELETED button that the clone is deleted. Can somebody help me, please?
In addition to missing } as was mentioned in the comments, there was a not-so-obvious problem with finding the <div> to clone. The lastChild was actually a text node containing the \n (newline), after the <div>. It's better to search for <div> by tag:
var itm = document
.getElementById('myList2')
.getElementsByTagName('div')[0];
Since there's only one <div> we can use the zero index to find this first and only one.
And for delete function you can use a similar approach and get the last <div> and remove it.
function appearafter() {
document.getElementById("buttonappear").style.display = "block";
document.getElementById("button").style.display = "block";
document.getElementById("hinzufuegen").style.display = "none";
}
function myFunction() {
var itm = document.getElementById("myList2").getElementsByTagName("div")[0];
var cln = itm.cloneNode(true);
document.getElementById("myList1").appendChild(cln);
}
function deleteFunction() {
var list1 = document.getElementById("myList1");
var divs = Array.from(list1.getElementsByTagName("div"));
// If the number of divs is 3, it means we're removing the last
// cloned div, hide the delete button.
if (divs.length === 3) {
document.getElementById("button").style.display = "none";
}
var lastDivToDelete = divs[divs.length - 1];
list1.removeChild(lastDivToDelete);
}
function allFunction() {
myFunction();
appearafter();
}
#button {
display: none;
}
#buttonappear {
display: none;
}
#test {
/* make it smaller so it's easier to show in a snippet */
width: 30px;
height: 30px;
background-color: red;
}
<button id="hinzufuegen" onclick="allFunction()">ADD</button>
<div id="myList1">
<button id="button" onclick="deleteFunction()">DELETE</button>
<div id="myList2">
<div id="test"></div>
</div>
</div>
<button onclick="allFunction()" id="buttonappear">ADD</button>
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 !!

The below code is working fine, but i want merge checked and click functions in single function. Is it possible?
$(function () {
if($("#enablepromo0").is(":checked"))
$("#PromoPanel").show(300);
else
$("#PromoPanel").hide(300);
});
$(function () {
$("#enablepromo0").click(function () {
if ($(this).is(":checked")) {
$("#PromoPanel").show(300);
} else {
$("#PromoPanel").hide(300);
}
});
});
Use the change event and trigger it, it can then detect the current state of the checkbox. I altered the code to toggle a class instead to avoid a "flash" initially.
$(function() {
$("#enablepromo0").on('change', function() {
let isChecked = !this.checked;
$("#PromoPanel").toggleClass("hidden", isChecked, {
duration: 300
});
}).trigger('change');
});
.panel {
border: solid lime 1px;
background: #ddffdd;
}
.hidden {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.1/jquery.min.js"></script>
Check to show: <input type="checkbox" id='enablepromo0' />
<div class="container">
<div id="PromoPanel" class="panel hidden">
<h2>Hi There</h2>Get stoked</div>
</div>
both function do the same job so i changed something to show an alert:
$(function () {
$("#enablepromo0").click(function () {
alert("dddddd")
if($("#enablepromo0").is(":checked"))
$("#PromoPanel").show(300);
else
$("#PromoPanel").hide(300);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<input type="checkbox" id='enablepromo0'/>
<div id="PromoPanel" style="border: 1px solid red; width:50px; heigth:50px; display:none;">uuu</div>
Move the code to its own function and call as required:
function showHide() {
if ($("#enablepromo0").is(":checked"))
$("#PromoPanel").show(300);
else
$("#PromoPanel").hide(300);
}
$(function () {
showHide();
$("#enablepromo0").click(function () {
showHide();
});
});
I have 3 divs on the page and I want them to change the color if they are scrolling. For example, all divs are blue, if they scroll to the first diva, change to green, change to green to the second diva, but the first will be blue again. I do not know how to go about it. I count on your help and tips. Maybe you've seen a similar example somewhere :)
According to your div color change dynamicaly bellow is the code
<!DOCTYPE HTML>
<html>
<head>
<style>
.divblue {
width: 100%;
height: 400px;
background-color: blue;
color: white;
}
.divgreen {
width: 100%;
height: 400px;
background-color: green;
color: white;
}
</style>
</head >
<body>
<div id="maindiv" style="width:100%;height:300px;overflow-y:scroll;">
<div id="fstdiv" class="divblue">
Hi test for first div
</div>
<div id="snddiv" class="divblue">
Hello test for second div
</div>
<div id="thrdiv" class="divblue">
Sir test for Third div
</div>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('#maindiv').scroll(function () {
var hT = $('#fstdiv').outerHeight();
var hH = $('#snddiv').outerHeight();
var tH = $('#thrdiv').outerHeight();
var wS = $(this).scrollTop();
$('#fstdiv').removeClass('divgreen').addClass('divblue');
$('#snddiv').removeClass('divgreen').addClass('divblue');
$('#thrdiv').removeClass('divgreen').addClass('divblue');
if (wS < 100) {
$('#fstdiv').removeClass('divblue').addClass('divgreen');
}
else if (wS > 400 && wS < 700) {
$('#snddiv').removeClass('divblue').addClass('divgreen');
}
else {
$('#thrdiv').removeClass('divblue').addClass('divgreen');
}
});

I am trying to highlight the single line of text in <textarea> with time delay. And I am wondering if I can choose a different color? The thing I wanted is when I click on the first <button>, the first line is highlighted into blue, click on the second <button>, 1 second later, the second line is highlighted into blue, lastly click on the third <button>, 2 second later, the third line is highlighted into yellow. I noticed I have a bug that I clicked on the button 3 times then the highlight doesn't work, but it is okay for me, I just want to know how to make the time delay and highlight with a different color. Thank you very much.
$( document ).ready(function() {
var str = 'line 1\nline 2\nline 3\n';
var textNumChar = str.length;
$('#str').val(str);
startPosition = 0;
$(".lines").click(function() {
var tarea = document.getElementById('str');
for(i=startPosition;i<textNumChar;i++)
{
if(str[i]=='\n') {
endposition = i;
break;
}
}
tarea.selectionStart = startPosition;
tarea.selectionEnd = endposition;
startPosition = endposition+1;
});
});

float: left;

width: 50px;height: 30px;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"> </script>

</div>
<textarea id="str" rows="6"></textarea>
You can use setTimeout() to set the delay in highlighting the text based on button id.
And ::selection css selector to style the portion of an element that is selected.
$( document ).ready(function() {
var str = 'line 1\nline 2\nline 3\n';
var textNumChar = str.length;
$('#str').val(str);
startPosition = 0;
$(".lines").click(function(e) {
var tarea = document.getElementById('str');
for(i=startPosition;i<textNumChar;i++)
{
if(str[i]=='\n') {
endposition = i;
break;
}
}
var time = 0;
var tar_id = e.target.id;
var colors;
if(tar_id == 'line1' ) { colors = 'red'; }
else if(tar_id == 'line2' ) { time = 1000; colors = 'blue'; }
else if(tar_id == 'line3' ) { time = 2000; colors = 'green'; }
setTimeout(function(){
tarea.selectionStart = startPosition;
tarea.selectionEnd = endposition;
startPosition = endposition+1;
$('body').addClass(colors);
}, time);
});
});
#container {
float: left;
}
button {
width: 50px;height: 30px;
}
.red ::selection {
color: red;
background: yellow;
}
.blue ::selection {
color: blue;
background: red;
}
.green ::selection {
color: green;
background: blue;
}
