DOM (Document Object Model) manipulation with jQuery allows you to easily interact with and modify HTML elements on a webpage. jQuery simplifies these tasks by providing a convenient and efficient way to select elements and perform various operations on them. To get started, make sure you have included the jQuery library in your HTML file.

 

You can do this by including the following script tag in the <head> section or just before the closing <body> tag

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

 

Selecting Elements

To manipulate elements, we need to select them first. jQuery offers powerful selectors similar to CSS selectors.

HTML

<div id="example">
  <p>Hello, World!</p>
  <p>How are you today?</p>
</div>

jQuery

// Selecting by tag name
var paragraphs = $('p');

// Selecting by ID
var exampleDiv = $('#example');

// Selecting by class
var someClassElements = $('.some-class');

// Selecting by attribute
var inputElements = $('[type="text"]');

 

Modifying Element Content

You can change the content of HTML elements using jQuery.

HTML

<p id="my-paragraph">This is some text.</p>
