Step-by-Step Guide: Building a Random Quotes Generator in JavaScript!

Introduction

Welcome back! In this article, we will create a simple and functional Random Quotes Generator using only JavaScript. This guide will take you through the process step-by-step, from HTML structure to JavaScript functionality. Let's get started!

Introduction

In today’s tutorial, we will create a random quotes generator that showcases a new quote every time you click a button. We will utilize HTML for the structure, CSS for styling, and JavaScript for functionality.

1. Setting Up the HTML Structure

To start, we need to create a basic HTML layout. Below is a sample structure:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css"> (* Link to your CSS *)
    <title>Random Quotes Generator</title>
</head>
<body>
    <div class="container">
        <div id="quote-box">
            <p class="quote-heading">"Your initial quote will be displayed here."</p>
            <p class="source">- Author Name</p>
            <span class="citation-year">Citation and Year</span>
        </div>
        <button id="load-quote">Next Quote</button>
    </div>
    <script src="script.js"></script> (* Link to your JavaScript *)
</body>
</html>

This structure consists of a container that holds the quote and a button to generate the next quote.

2. JavaScript Functionality

Next, we will implement the logic for generating the quotes using JavaScript. You will need to create a JavaScript file, script.js, and include the following code:

const quotes = [
    ( quote: "The best way to predict your future is to create it.", source: "Peter Drucker", citation: "Leadership", year: 2000 ),
    ( quote: "Life is 10% what happens to us and 90% how we react to it.", source: "Charles R. Swindoll", citation: "Motivation", year: 1999 ),
    ( quote: "The only way to do great work is to love what you do.", source: "Steve Jobs" ),
    // Add more quotes here
];

function getRandomQuote() (
    const randomIndex = Math.floor(Math.random() * quotes.length);
    return quotes[randomIndex];
)

function printQuote() (
    const randomQuote = getRandomQuote();
    let quoteString = `<p class="quote-heading">${randomQuote.quote)</p>`;
    quoteString += `<p class="source">- $(randomQuote.source)</p>`;
    
    if (randomQuote.citation) (
        quoteString += `<span class="citation">${randomQuote.citation)</span>`;
    }
    
    if (randomQuote.year) (
        quoteString += `<span class="year">${randomQuote.year)</span>`;
    }

    document.getElementById('quote-box').innerHTML = quoteString;
}

document.getElementById('load-quote').addEventListener('click', printQuote);

// Optional: Auto-generate a new quote every 15 seconds
setInterval(printQuote, 15000);

Breakdown of the JavaScript Code

Quotes Array: It stores multiple quote objects that include the quote text, source, citation, and year.
getRandomQuote Function: This function generates a random index and retrieves a corresponding quote object from the quotes array.
printQuote Function: This function constructs the HTML for the selected quote and inserts it into the quote box.
Event Listener: The button is set up to call the printQuote function each time it's clicked, displaying a new quote.
Auto-Generation: Optionally, you can set a timer to change quotes automatically every 15 seconds.

Conclusion

Congratulations! You have successfully built a random quotes generator using JavaScript. You can further enhance it by adding more quotes, styling the layout with CSS, or even integrating it into a larger project.
