I would like to change the content of a div. I have three divs:
<div
class="box1"
style="height: 200px; width: 200px; background-color: red"
>
A
</div>
<br />
<div
class="box2"
style="height: 200px; width: 200px; background-color: blue"
>
<label for="">tex</label>
<input type="text" />
</div>
<br />
<div
class="box3"
style="height: 200px; width: 200px; background-color: yellow"
>
C
</div>
when the page is ready the 2 and 3rd box displays none:
function hideElementBoxOnLoad() {
let box1 = document.querySelector(".box1");
let box2 = document.querySelector(".box2");
let box3 = document.querySelector(".box3");
box2.style.display = "none";
box3.style.display = "none";
}
$(document).ready(hideElementBoxOnLoad);
I want a click that toggles the content of box2 and box3 into box1 and then back to box1 content:
function changeContent() {
let chang = true;
let box1 = document.querySelector(".box1");
let box2 = document.querySelector(".box2");
let box3 = document.querySelector(".box3");
let box2Content = box2.textContent;
let box3Content = box3.textContent;
if (chang) {
box1.textContent = box2Content;
chang = !chang;
if ((box1.textContent === box2Content)) {
box1.textContent = box3Content;
}
}
}
let btn = document.getElementById("btn");
btn.addEventListener("click", changeContent);
So far it worked but it does not display the content of box2 only box3. what did i do wrong and what better way can i toggle with a boolean.
See below
Instead of trying to swap content between each div just use JS to go through the array of them and swap an active class between them;
var boxes = document.getElementsByClassName('box');
var change = document.getElementById('change');
var counter = 0;
change.addEventListener('click', function(){
boxes[counter].classList.remove('active');
boxes[counter].nextElementSibling.classList.add('active');
counter++;
if(counter === boxes.length) {
counter = 0;
boxes[0].classList.add('active');
}
});
.box {
display: none;
width: 100px;
height: 100px;
background-color: gray;
}
.box.active {
display:block
}
<div class="box active">A</div>
<div class="box">B</div>
<div class="box">C</div>
<button id="change">Change Content</button>
im not completely sure if i understood ur question.
but below u can see and even test with the snippet button.
the button now add what ever content in in the yellow box, and whats in the input field of the blue box into the red box. listing them downwards.
if you want to replace the content completely.
just change the logic to box1.innerHTML += spacer+box3.innerHTML+spacer+input.value
this is the most simple way to do it thats easy to understand just by reading the code i think.
hope this helps!
function changeContent() {
//the button
const btn = document.getElementById("btn");
//the boxes
const box1 = document.getElementById("box1");
const box2 = document.getElementById("box2");
const box3 = document.getElementById("box3");
//a spacer
const spacer = "<br>";
//the input field
const input = document.getElementById("input");
//logic
box1.innerHTML += spacer+box3.innerHTML+spacer+input.value
}

List of bugs :-
You had declared the var chang locally instead of globally, which make it true whenever you runs the function.
You are directly writing value from one tag to another, which causing the data loss, when you run your function second time.
For example :- When you click the button first time, the data is swapped, but for the second click, the data first div is lost and cannot be brought back...
Solution :- Store the data in an array in document.ready event handler and extract data from the array to update you html tags.
function hideElementBoxOnLoad() {
let box1 = document.querySelector(".box1");
let box2 = document.querySelector(".box2");
let box3 = document.querySelector(".box3");
box2.style.display = "none";
box3.style.display = "none";
content = [box1.textContent, box2.textContent, box3.textContent];
let btn = document.getElementById("btn");
btn.addEventListener("click", changeContent);
}
var content = [];
window.onload = (hideElementBoxOnLoad);
var index = 0;
function changeContent() {
let chang = true;
let box1 = document.querySelector(".box1");
/* let box2 = document.querySelector(".box2");
let box3 = document.querySelector(".box3");
let box2Content = box2.textContent;
let box3Content = box3.textContent;
if (chang) {
box1.textContent = box2Content;
chang = !chang;
if ((box1.textContent === box2Content)) {
box1.textContent = box3Content;
}
}
*/
function cycle(n, x = 0, y = content.length - 1, a = 1) {
n += a;
if (n > y) return x;
if (n < x) return y;
return n;
}
index = cycle(index);
box1.textContent = content[index];
}
<div class="box1" style="height: 200px; width: 200px; background-color: red">
A
</div>
<br />
<div class="box2" style="height: 200px; width: 200px; background-color: blue">
<label for="">tex</label>
<input type="text" />
</div>
<br />
<div class="box3" style="height: 200px; width: 200px; background-color: yellow">
C
</div>
<button id="btn"> CLICK ME </button>
Explaination
Here I first stored the tags textContent in a array content, in the starting of the code.
Then, inside the button click handler, a simple cycle function to cycle on the values stored inside the content array.

<h2>NOTE TAKER</h2>
<h6>Add A New Note:</h6>
<form id="Form" action="#">
<label class="ntag" for="note">Note:</label>
<input class="ntag" name="note" id="Note" type="text" placeholder="Write a note">
<button id="Add">Add Note</button>
</form>
<div class="theTable">
<table id="noteTable">
<tr id="Headers" class="headers">
<th></th>
</tr>
</table>
</div>
<div class="model-container" id="model">
<div class="model">
<button class="close" id="close">Close Me</button>
</div>
</div>
I'm not sure why but the notes repeat in the model-container, after you make another note the first one is still there with the second one right after it.
I thought that it could be the placement, so i put it in the btn function, but it duplicated as well; also sorry for how ugly this is, I'm just focused on the JavaScript
If you inspect the source after adding a few notes, you'll notice that it looks like this, assuming I added notes "one", "two" and "three":
It's putting it there because of this line of javascript:
model.append(note.value);
The .append() method doesn't wipe out anything in the <div id="model">, it just adds on to whatever is in there by dumping it after the button or dumping after any existing text.
To avoid erasing the "Close Me" button you'll probably want another div specifically for the text so that instead of using .append() you can just set the .textContent of the element each time. This would be destructive in a way that you wouldn't want to do this on the parent element, because it would wipe out the button. .append() is what is retaining the previous stuff when you click "View Detail."
<div class="model-container" id="model">
<div class="model">
<button class="close" id="close">Close Me</button>
</div>
<div id="txtDetails"><div>
</div>
So instead of using .append() just set the text of <div id="txtDetails"> to what you want it to say by setting the .textContent.
I also added a "data-text" attribute to the button on creation so it would be easier to fish out the text instead of navigating the parent elements and across elements.
Finally, on the click listener event I made it take whatever is stored in the "data-text" attribute and place that into <div id="txtDetails"> so that each "View Details" click would only show what is relevant for that particular note. This method is destructive in that it wipes out and replaces anything in <div id="txtDetails"> with each click but leaves the button in the modal alone.
const form = document.querySelector("#Form");
const note = document.querySelector("#Note");
const table = document.querySelector("#noteTable");
const count = 0;
form.addEventListener("submit", (e) => {
e.preventDefault();
if(note.value !== '')
{
const btn = document.createElement("button");
btn.innerHTML = "View Details";
btn.setAttribute('data-text', note.value);
const row = table.insertRow();
const noteRow = row.insertCell();
const viewD = row.insertCell();
noteRow.innerHTML = note.value;
viewD.append(btn);
note.value = "";
btn.addEventListener("click", () => {
document.getElementById('txtDetails').textContent = btn.getAttribute('data-text');
model.classList.add("show");
});
const close = document.querySelector("#close");
close.addEventListener("click", () => {
model.classList.remove("show");
});

I am trying to make a "meet the staff" section that has hidden bios that display on click. Right now the div displays as it should, but only disappears when the original button is clicked again. I am needing some additional javascript to hide any opened divs when a different (or same) button is clicked. I don't know enough javascript to know what to try in order to make this happen. Thanks in advance!
HTML
<div id="lastname" class="toggle-div" style="display: none;">
<div><p>bio</p>
</div>
</div>
<button class="bio-button" onclick="myBiof()">Click for Bio</button>
Javascript
<script>
function myBiof() {
var y = document.getElementById("lastname");
if (y.style.display === "block") {
y.style.display = "none";
} else {
y.style.display = "block";
}
}
</script>
You will need to add some attributes to your HTML to keep track of which item is active, what item a button controls and which ones should be hidden from screen readers. aria-controls aria-expanded and aria-hidden do just that. Once a button is clicked... if it is currently open, just close it (remove active) and toggle the appropriate attributes. If it is not open, close all of them (remove active), open the one you clicked on (add active) and toggle the appropriate attributes. Here is a simple example:
const buttons = document.querySelectorAll("button");
const people = document.querySelectorAll(".person");
const handleClick = (event) => {
const clickedBtn = event.target;
if (clickedBtn.getAttribute("aria-expanded") === "true") {
let personId = clickedBtn.getAttribute("aria-controls");
let person = document.getElementById(personId);
person.classList.remove("active");
person.setAttribute("aria-hidden", "true");
clickedBtn.setAttribute("aria-expanded", "false");
} else if (clickedBtn.getAttribute("aria-expanded") === "false") {
people.forEach(person => {
person.classList.remove("active")
person.setAttribute("aria-hidden", "true");
});
buttons.forEach(button => button.setAttribute("aria-expanded", "false"));
let personId = clickedBtn.getAttribute("aria-controls");
let person = document.getElementById(personId);
person.classList.add("active");
person.setAttribute("aria-hidden", "false");
clickedBtn.setAttribute("aria-expanded", "true");
}
}
buttons.forEach(button => button.addEventListener("click", handleClick));

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);

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();

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.

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.

setTimeout(function(){

I have seen many similar problems but when I try them they end up failing. It has gotten to the point where my code is totally messed up and I need some help both cleaning it up and fixing my issue. (using chrome)
So far I have tried selecting the value of the form and putting that into a div,
I have tried to use the button as just a link to start the script so that the page doesn't reset and also many other answers found on-line, none of them are helping so I am asking for a personalised help.

For clarification this code is not meant to keep the comments from the form nor is it meant to be a fully functioning site. I am just making slight modifications to some code so that I can hand it in as a college assignment.
Using onclick and pass the event inside:
<button style="margin-left:310px;" onclick="on_comment_add(event)">Submit</button>
And disable the default form submit action:
function on_comment_add(e) {
e.preventDefault()
var main = document.getElementById("div1");
var add_user_name = document.createElement("div");
var add_user_comment = document.createElement("div");
add_user_name.setAttribute("id", "add_user_name");
add_user_comment.setAttribute("id", "add_user_comment");
var node_1 = document.createElement("div");
node_1.innerHTML= document.getElementById("user_name").value;
var node_2 = document.createElement("div");
node_2.innerHTML = document.getElementById("user_comment").value;
add_user_name.appendChild(node_1);
add_user_comment.appendChild(node_2);
var element = document.createElement("div");
element.setAttribute("id", "display_comment_div");
element.appendChild(add_user_name);
element.appendChild(add_user_comment);
main.appendChild(element);
return false;
}
Workable example: https://jsfiddle.net/kingychiu/z6gnqswn/
Change type to "button" to prevent automatical form sending and add parentheses to onmousedown expression:
<button type="button" style="margin-left:310px;" onmousedown="return on_comment_add()">Submit</button>
Then change this
add_user_name.appendChild(node_1);
add_user_comment.appendChild(node_2);
to this (since node_1, node_2 are values, not elements):
add_user_name.innerHTML = node_1;
add_user_comment.innerHTML = node_2;
And remove that line
main.innerHTML = element;
above
return false;
That should work.
