Build A Hangman Game in HTML CSS and JavaScript

Build A Hangman Game in HTML CSS and JavaScript

Hangman is the classic word-guessing game you’ve likely enjoyed playing. But as a beginner web developer, have you ever thought about building your own Hangman game? Building a hangman game is not only fun and engaging but also provides an excellent opportunity to enhance your web development and problem-solving skills.

If you’re unfamiliar, Hangman is a word-guessing game where players try to guess all the letters of a randomly generated word within a given number of tries. There is also a hangman illustration that will progressively appear on the gallows for each incorrect guess.

In this beginner-friendly blog post, I’ll show you how to build a Hangman game in HTML, CSS, and JavaScript. By creating this game, you’ll gain practical experience and dive into essential concepts of web development, such as DOM manipulation, event handling, conditional statements, array usage, and many more.

Video Tutorial of Hangman Game HTML & JavaScript

If you enjoy learning through video tutorials, the above YouTube video is an excellent resource. In the video, I’ve explained each line of code and provided informative comments to make the process of building your own Hangman game beginner-friendly and easy to follow.

However, if you like reading blog posts or want a step-by-step guide for building this game, you can continue reading this post. By the end of this post, you’ll have your own Hangman game that you can play or show off to your friends.

Steps to Build Hangman Game in HTML & JavaScript

To build a Hangman game using HTML, CSS, and JavaScript, follow these step-by-step instructions:

  1. Create a folder. You can name this folder whatever you want, and inside this folder, create the mentioned files.
  2. Create an index.html file. The file name must be index and its extension .html
  3. Create a style.css file. The file name must be style and its extension .css
  4. Create a scripts folder with word-list.js and script.js files. The extension of the files must be .js and files should be inside the scripts folder.
  5. Download and place the Images folder in your project directory. This folder includes the necessary images and gifs for the game.

To start, add the following HTML codes to your index.html file. These codes include essential HTML elements, such as a modal box and a container for the game. Using JavaScript later, we’ll add or modify these elements and randomize game letters, hints, and keyboard keys.

    <div class="game-modal">
        <div class="content">
            <img src="#" alt="gif">
            <h4>Game Over!</h4>
            <p>The correct word was: <b>rainbow</b></p>
            <button class="play-again">Play Again</button>
        </div>
    </div>
    <div class="container">
        <div class="hangman-box">
            <img src="#" draggable="false" alt="hangman-img">
            <h1>Hangman Game</h1>
        </div>
        <div class="game-box">
            <ul class="word-display"></ul>
            <h4 class="hint-text">Hint: <b></b></h4>
            <h4 class="guesses-text">Incorrect guesses: <b></b></h4>
            <div class="keyboard"></div>
        </div>
    </div>
</body>
</html>

Next, add the following CSS codes to your style.css file to apply visual styling to your game: color, font, border, background, etc. Now, if you load the web page in your browser, you will see the Hangman game with its various styled elements. You can play around with colors, fonts, borders, backgrounds, and more to give your Hangman game a unique and appealing look.

Finally, add the following JavaScript code to your script.js file. This script code will be responsible for the game’s logic, including generating a random word, managing user input, keeping track of guessed letters, checking for correct guesses, and updating the hangman’s visual representation as the game progresses.

const wordDisplay = document.querySelector(".word-display");
const guessesText = document.querySelector(".guesses-text b");
const keyboardDiv = document.querySelector(".keyboard");
const hangmanImage = document.querySelector(".hangman-box img");
const gameModal = document.querySelector(".game-modal");
const playAgainBtn = gameModal.querySelector("button");

// Initializing game variables
let currentWord, correctLetters, wrongGuessCount;
const maxGuesses = 6;

const resetGame = () => {
    // Ressetting game variables and UI elements
    correctLetters = [];
    wrongGuessCount = 0;
    hangmanImage.src = "images/hangman-0.svg";
    guessesText.innerText = `${wrongGuessCount} / ${maxGuesses}`;
    wordDisplay.innerHTML = currentWord.split("").map(() => `<li class="letter"></li>`).join("");
    keyboardDiv.querySelectorAll("button").forEach(btn => btn.disabled = false);
    gameModal.classList.remove("show");
}

const getRandomWord = () => {
    // Selecting a random word and hint from the wordList
    const { word, hint } = wordList[Math.floor(Math.random() * wordList.length)];
    currentWord = word; // Making currentWord as random word
    document.querySelector(".hint-text b").innerText = hint;
    resetGame();
}

const gameOver = (isVictory) => {
    // After game complete.. showing modal with relevant details
    const modalText = isVictory ? `You found the word:` : 'The correct word was:';
    gameModal.querySelector("img").src = `images/${isVictory ? 'victory' : 'lost'}.gif`;
    gameModal.querySelector("h4").innerText = isVictory ? 'Congrats!' : 'Game Over!';
    gameModal.querySelector("p").innerHTML = `${modalText} <b>${currentWord}</b>`;
    gameModal.classList.add("show");
}

const initGame = (button, clickedLetter) => {
    // Checking if clickedLetter is exist on the currentWord
    if(currentWord.includes(clickedLetter)) {
        // Showing all correct letters on the word display
        [...currentWord].forEach((letter, index) => {
            if(letter === clickedLetter) {
                correctLetters.push(letter);
                wordDisplay.querySelectorAll("li")[index].innerText = letter;
                wordDisplay.querySelectorAll("li")[index].classList.add("guessed");
            }
        });
    } else {
        // If clicked letter doesn't exist then update the wrongGuessCount and hangman image
        wrongGuessCount++;
        hangmanImage.src = `images/hangman-${wrongGuessCount}.svg`;
    }
    button.disabled = true; // Disabling the clicked button so user can't click again
    guessesText.innerText = `${wrongGuessCount} / ${maxGuesses}`;

    // Calling gameOver function if any of these condition meets
    if(wrongGuessCount === maxGuesses) return gameOver(false);
    if(correctLetters.length === currentWord.length) return gameOver(true);
}

// Creating keyboard buttons and adding event listeners
for (let i = 97; i <= 122; i++) {
    const button = document.createElement("button");
    button.innerText = String.fromCharCode(i);
    keyboardDiv.appendChild(button);
    button.addEventListener("click", (e) => initGame(e.target, String.fromCharCode(i)));
}

getRandomWord();
playAgainBtn.addEventListener("click", getRandomWord);

That’s all! To understand JavaScript code better, I recommend watching the above video tutorial, paying close attention to the code comments, and experimenting with the code.

Conclusion and Final Words
