Introduction

In this tutorial, we will explore attribute and pseudo-selectors in jQuery. These selectors provide a more refined way of targeting elements based on their attributes or their state/position within the Document Object Model (DOM).

By the end of this tutorial, you will learn:
- What attribute and pseudo-selectors are
- How to use them to select elements in jQuery
- Some practical examples of their application

Prerequisites:
- Basic knowledge of HTML and CSS
- Familiarity with JavaScript and jQuery basics

Step-by-Step Guide

Attribute Selectors

Attribute selectors in jQuery are used to select elements with a specific attribute or attribute value. The basic syntax is $("element[attribute='value']").

Example:

$("a[target='_blank']") // This selects all <a> elements with a target attribute value of '_blank'

Pseudo-Selectors

Pseudo-selectors in jQuery are used to select elements based on their state or position within the DOM. Examples include :first, :last, :even, :odd, etc. The basic syntax is $("element:pseudo-selector").

Example:

$("div:first") // This selects the first <div> element

Code Examples

Attribute Selector Example

// Select all input elements with a type of 'text'
$("input[type='text']").css("background-color", "yellow");

// Expected result: All text input fields will have a yellow background

Pseudo-Selector Example

// Select all even <li> elements
$("li:even").css("background-color", "lightgrey");

// Expected result: All even <li> elements will have a light grey background
