jquery

What is jquery?

The jQuery npm package is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, and animation much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.

What are jquery's main functionalities?

DOM Traversal and Manipulation

Easily select and manipulate HTML elements. This code changes the text of all paragraph elements to 'Hello World'.

$( 'p' ).text( 'Hello World' );

Event Handling

Quickly handle events like clicks. This code sets up an alert to be displayed when any button is clicked.

$( 'button' ).click( function() { alert( 'Button clicked!' ); } );

Animation

Perform animations on elements. This code makes a div element slide up slowly.

$( 'div' ).slideUp( 'slow' );

AJAX

Facilitate asynchronous HTTP (Ajax) requests. This code fetches the content of test.html and inserts it into the body of the current page.

$.ajax({ url: 'test.html', success: function(data) { $( 'body' ).html( data ); } });
