How Our DOM Sandbox Works

Our DOM Sandbox allows you to write JavaScript code that manipulates the DOM in a completely isolated environment.

Supported DOM Operations:

Element Selection - getElementById, querySelector, getElementsByClassName
Content Manipulation - innerHTML, innerText, textContent
Attribute Management - setAttribute, getAttribute, removeAttribute
Style Changes - element.style.property = value
Class Manipulation - classList.add, remove, toggle
Event Handling - addEventListener, removeEventListener
DOM Traversal - parentNode, childNodes, nextSibling
Element Creation - createElement, appendChild, removeChild

Available DOM Elements:

#counter - Counter display element
#color-box - Color box for style testing
#todo-list - Todo list container
.todo-item - Individual todo items
.sample-card - Info card component

DOM Sandbox FAQ

Yes! The sandbox uses security restrictions that block dangerous operations including eval(), fetch(), localStorage, and more. You can choose between Safe, Strict, and Full Access modes.

Absolutely! You can add event listeners to any element. Example: document.getElementById('counter').addEventListener('click', () => console.log('Clicked!'))

The sandbox catches all errors and displays them in the console output. Your actual page remains unaffected and you can simply reset the DOM and try again.

DOM API Reference

Select Elements

document.getElementById('id')

document.querySelector('.class')

Modify Content

element.innerText = 'Hello'

element.innerHTML = '<b>Bold</b>'

Change Styles

element.style.color = 'red'

element.classList.add('active')

Create Elements

const div = document.createElement('div')

parent.appendChild(div)

Events

element.addEventListener('click', fn)

element.removeEventListener('click', fn)

Common DOM Patterns

Change Text

document.getElementById('counter').innerText = '100'

Change Style

document.getElementById('color-box').style.backgroundColor = 'blue'

Add Element

Console Log

console.log('Value:', document.getElementById('counter').innerText)
