Hello guys, today I am going to show you How to build a JavaScript Random Quote Generator using HTML CSS & JavaScript, in this video, I will create a simple quote generator.

JavaScript Random Quote Generator step by step

Step 1 — Creating a New Project

In this step, we need to create a new project folder and create files(index.html, style.css, quotes.js) inside the folder. for creating a Random Quote Generator. In the next step, you will start creating the structure of the webpage.

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> 
Enter fullscreen mode Exit fullscreen mode

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>
Enter fullscreen mode Exit fullscreen mode

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;
}
Enter fullscreen mode Exit fullscreen mode

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}`;
}
Enter fullscreen mode Exit fullscreen mode

Come on, this ain't a thing. You can create an API for serving quotes and a simple Json db for storing and updates, which is a better approach. Plus, this is just a client to such API where you had hard coded quotes.

Thanks :) You are right, but this is only how we can deal with the array, also we can use API and db

So, you are saying you wrote this post to show how to handle an array. Not, right!

Don't get me started on heading, according to the former, it should construct a quote from random words because being a generator. A generator takes raw materials and process it into a useful form. Bro, I'm done with this and now I take this post as your side/fun tutorial for newbies. Concluded, not worth for anyone above the bar.

Yeah, there's already API available for generating quotes on the internet. It's a better approach for this project.

Just a suggestion, you should add a codepen to the blog, so the user get to interact and see what you have built.

Nice article. Keep up the good work brother. An alternative to hard coding quotes is to query quotes from an API. You will be able to get a much larger selection.
