Introduction to JavaScript on GitHub Pages: Hosting and Sharing Projects Online

GitHub Pages is a powerful platform for hosting and sharing web projects and software projects online. It provides an easy way to create, manage and share your projects and gives you control over how they are presented. But one of the most interesting features is the support for JavaScript. With JavaScript, you can write highly interactive pages with many dynamic elements, and GitHub Pages makes it easy to include them in your project.

JavaScript Support in GitHub Pages

GitHub Pages supports the full range of JavaScript libraries and frameworks, like React, jQuery, Vue and Angular. You can write the code directly in your HTML or use external JavaScript files from any public or private repository. You can also reference JavaScript from external content delivery networks (CDNs) or use your own hosting service. It's easy to get started with JavaScript in GitHub Pages. Once you've set up your project repository, you can create a branch for your JavaScript files and use the GitHub Pages build system to process the files. GitHub Pages will render the JavaScript in your project and you can use the same tools and techniques you would use when building a website.

Examples of JavaScript in GitHub Pages

Let's take a look at some examples of how JavaScript can be used in GitHub Pages.

Dynamic Forms

You can use JavaScript to build dynamic forms that respond to user input. For example, let's create a simple form that creates a greeting based on a user's name. We'll use HTML and JavaScript to build the form and style it with CSS.


<form id="greeting-form">
  <label for="name">Name: </label>
  <input type="text" id="name">
  <button type="submit">Submit</button>
</form>

<div id="greeting-output"></div>

<script>
  const form = document.querySelector('#greeting-form');
  const output = document.querySelector('#greeting-output');

  form.addEventListener('submit', e => {
    e.preventDefault();

    const name = form.querySelector('#name').value;
    output.textContent = `Hello, ${name}!`;
  });
</script>

When the form is submitted, the JavaScript code is run and the greeting is displayed in the output.

Dynamic Content

You can also use JavaScript to create dynamic content. For example, let's create a simple list of items that can be toggled between visible and hidden. We'll use HTML and JavaScript to build the list and style it with CSS.


<ul id="items">
  <li data-visible="true">Item 1</li>
  <li data-visible="false">Item 2</li>
  <li data-visible="false">Item 3</li>
</ul>

<button id="toggle-items">Toggle Items</button>

<script>
  const button = document.querySelector('#toggle-items');
  const items = document.querySelectorAll('#items li');

  button.addEventListener('click', () => {
    items.forEach(item => {
      let visible = item.dataset.visible === 'true';
      item.dataset.visible = !visible;
      item.style.display = visible ? 'none' : 'block';
    });
  });
</script>

When the button is clicked, the JavaScript code is run and the list items will be toggled between visible and hidden.
