Document Object Model (DOM) Manipulation
The Document Object Model (DOM) is a tree-like representation of an HTML document, and JavaScript provides several methods for manipulating the DOM. DOM manipulation is the process of changing the content, structure, or style of an HTML document using JavaScript.
Here is an example of changing the content of an HTML element using JavaScript:
let header = document.getElementById("header");
header.innerHTML = "New Header Content";
In the example, the getElementById method is used to get a reference to an HTML element with the id "header". The innerHTML property is then used to change the content of the element to "New Header Content".
Here is another example of changing the style of an HTML element using JavaScript:
let header = document.getElementById("header");
header.style.backgroundColor = "red";
In the example, the getElementById method is used to get a reference to an HTML element with the id "header". The style property is then used to change the background color of the element to red.
DOM manipulation is an important aspect of web development, as it allows you to dynamically update the content, structure, and style of an HTML document based on user interactions or other events. Understanding DOM manipulation and how to use JavaScript to manipulate the DOM is an important part of web development and JavaScript programming.
