**Question:**
You are tasked with creating a function in JavaScript that dynamically generates a complex DOM structure, including nested elements with specific attributes and styles. Additionally, this function should open a new window, clone the generated DOM structure, and insert it into the new window’s document.
Implement the `createAndCloneDOM` function which accomplishes the following:
1. Creates a `div` element with an id of `container`.
2. Within this `div`, create a nested structure:
– An `h1` element with the text “Main Title”.
– A `p` element with the text “This is a paragraph.” and a class name `intro`.
– An `ul` element containing three `li` elements with the text “Item 1”, “Item 2”, and “Item 3”.
3. Styles the `div` with a border of `2px solid black` and padding of `10px`.
4. Appends this `div` to the `body` of the current document.
5. Opens a new window, clones the entire `div` structure, and inserts it into the new window’s document.
Which of the following options correctly implements the `createAndCloneDOM` function?
**Options:**
A)
“`javascript
function createAndCloneDOM() {
let container = document.createElement(‘div’);
container.id = ‘container’;
let title = document.createElement(‘h1’);
title.textContent = ‘Main Title’;
container.appendChild(title);
let paragraph = document.createElement(‘p’);
paragraph.textContent = ‘This is a paragraph.’;
paragraph.className = ‘intro’;
container.appendChild(paragraph);
let list = document.createElement(‘ul’);
for (let i = 1; i <= 3; i++) {
let listItem = document.createElement('li');
listItem.textContent = `Item ${i}`;
list.appendChild(listItem);
}
container.appendChild(list);
container.style.border = '2px solid black';
container.style.padding = '10px';
document.body.appendChild(container);
let newWindow = window.open('', '', 'width=400,height=300');
newWindow.document.body.appendChild(container.cloneNode(true));
}
```
B)
```javascript
function createAndCloneDOM() {
let container = document.createElement('div');
container.id = 'container';
let title = document.createElement('h1');
title.textContent = 'Main Title';
container.appendChild(title);
let paragraph = document.createElement('p');
paragraph.textContent = 'This is a paragraph.';
paragraph.className = 'intro';
container.appendChild(paragraph);
let list = document.createElement('ul');
for (let i = 1; i <= 3; i++) {
let listItem = document.createElement('li');
listItem.textContent = `Item ${i}`;
list.appendChild(listItem);
}
container.appendChild(list);
container.style.border = '2px solid black';
container.style.padding = '10px';
document.body.appendChild(container);
let newWindow = window.open('', '', 'width=400,height=300');
newWindow.document.write('
‘);
newWindow.document.close();
}
“`
C)
“`javascript
function createAndCloneDOM() {
let container = document.createElement(‘div’);
container.id = ‘container’;
let title = document.createElement(‘h1’);
title.textContent = ‘Main Title’;
container.appendChild(title);
let paragraph = document.createElement(‘p’);
paragraph.textContent = ‘This is a paragraph.’;
paragraph.className = ‘intro’;
container.appendChild(paragraph);
let list = document.createElement(‘ul’);
for (let i = 1; i <= 3; i++) {
let listItem = document.createElement('li');
listItem.textContent = `Item ${i}`;
list.appendChild(listItem);
}
container.appendChild(list);
container.style.border = '2px solid black';
container.style.padding = '10px';
document.body.appendChild(container);
let newWindow = window.open('', '', 'width=400,height=300');
let newDoc = newWindow.document;
newDoc.open();
newDoc.write('
newDoc.write(container.outerHTML);
newDoc.write(‘‘);
newDoc.close();
}
“`
D)
“`javascript
function createAndCloneDOM() {
let container = document.createElement(‘div’);
container.id = ‘container’;
let title = document.createElement(‘h1’);
title.textContent = ‘Main Title’;
container.appendChild(title);
let paragraph = document.createElement(‘p’);
paragraph.textContent = ‘This is a paragraph.’;
paragraph.className = ‘intro’;
container.appendChild(paragraph);
let list = document.createElement(‘ul’);
for (let i = 1; i <= 3; i++) { let listItem = document.createElement('li'); listItem.textContent = `Item ${i}`; list.appendChild(listItem); } container.appendChild(list); container.style.border = '2px solid black'; container.style.padding = '10px'; document.body.appendChild(container); let newWindow = window.open('', '', 'width=400,height=300'); newWindow.document.body.innerHTML = container.outerHTML; } ``` **Correct Answer:** A) Explanation: Option A correctly implements the function by creating the necessary DOM structure, styling it, appending it to the body, and then cloning the `div` and appending the cloned node to the new window's document body. This approach ensures that the entire structure, including event listeners and styles, is properly duplicated in the new window.
