JavaScript allows you to dynamically interact with HTML elements through the Document Object Model (DOM). Here's a quick overview of key concepts and techniques:
📌 Core DOM Operations
Select Elements
Usedocument.getElementById()
,document.querySelector()
, ordocument.querySelectorAll()
to target elements.Modify Content
Update text withtextContent
orinnerText
, change attributes viasetAttribute()
, and manipulate styles usingstyle
.Event Handling
Attach listeners usingaddEventListener()
to respond to user interactions like clicks or form submissions.
🛠️ Practical Examples
Changing Text
document.querySelector("h1").textContent = "Hello, DOM!";
Adding Event
button.addEventListener("click", function() { alert("Button clicked!"); });
Creating Elements
const newPara = document.createElement("p"); newPara.textContent = "This is a new paragraph."; document.body.appendChild(newPara);
