JavaScript Random Quote Generator step by step

Step 2 — Setting Up the basic structure

In this step, we will add the HTML code to create the basic structure of the project.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>How to build a JavaScript Random Quote Generator</title>
    <link rel="stylesheet" href="style.css">
    <script src="quotes.js"></script>
</head>
<body>

</body>
</html>

This is the base structure of most web pages that use HTML.
Add the following code inside the <body> tag:

<section class="randomQuote">
        <header>
            <h2>Quote of the Day</h2>
            <p>Press the below button to receive a random quote!</p>
        </header>
        <div class="quotesOutput">
            <p id="generatedQuote">"The greatest glory in living lies not in never falling, but in rising every time we fall."</p>
            <span id="AuthorName">--Nelson Mandela</span>
        </div>
        <button onclick="generateQoute()">New Quote</button>
</section>

Step 3 — Adding Styles for the Classes

In this step, we will add styles to the section class Inside style.css file

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300&display=swap');
* {
    padding: 0;
    margin: 0;
    font-family: 'Poppins', sans-serif;
}
header {
    text-align: center;
    background: #4b00ff;
    color: #fff;
    padding: 10px 0;
    margin-bottom: 10px;
}
.quotesOutput {
    text-align: center;
    background: #dde1ff;
    padding: 20px;
    min-height: 50px;
    margin-bottom: 20px;
}
button {
    display: block;
    width: 150px;
    height: 40px;
    font-size: 16px;
    font-weight: 600;
    background: #4b00ff;
    color: #fff;
    border: transparent;
    margin: auto;
    cursor: pointer;
}
p#generatedQuote {
    font-size: 16px;
    font-weight: 800;
}

Step 4 — Adding some lines of JavaScript code

In this step, we will add some JavaScript code to build Quote Generator.

const arrayOfQuotes = [
    {'author': 'Nelson Mandela', 
        'quote': 'The greatest glory in living lies not in never falling, but in rising every time we fall.'
    },
    {'author': 'Walt Disney', 
        'quote': 'The way to get started is to quit talking and begin doing.'
    },
    {'author': 'Eleanor Roosevelt', 
        'quote': 'If life were predictable it would cease to be life, and be without flavor.'
    },
    {'author': 'Oprah Winfrey', 
        'quote': 'If you look at what you have in life, you`ll always have more. If you look at what you don`t have in life, you`ll never have enough'
    },
    {'author': 'James Cameron', 
        'quote': 'If you set your goals ridiculously high and it`s a failure, you will fail above everyone else`s success'
    },
    {'author': 'Elbert Hubbard', 
        'quote': 'Do not take life too seriously. You will not get out alive.'
    },
    {'author': 'John Lennon', 
        'quote': 'Life is what happens when you`re busy making other plans.'
    }
];

// Create a function to generate quote from array

function generateQoute(){
    const random = Number.parseInt(Math.random()*arrayOfQuotes.length + 1);
    document.querySelector("#generatedQuote")
    .textContent = `\"${arrayOfQuotes[random].quote}\"`;
    document.querySelector("#AuthorName")
    .textContent = `--${arrayOfQuotes[random].author}`;
}
