jQuery Tutorial

jQuery is a fast, small, and feature-rich JavaScript library. It simplifies HTML document traversal, event handling, animation, and AJAX interactions for rapid web development.

Why Learn jQuery?

  • Simplifies DOM selection with powerful CSS-like selectors.
  • Handles cross-browser differences automatically.
  • Provides easy-to-use effects and animations.
  • Makes AJAX calls easier and cleaner.
  • Large plugin ecosystem for almost anything.

Example: Hello jQuery


<!-- Load jQuery -->
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<!-- HTML -->
<button id="btn">Click me</button>
<div id="msg"></div>

<!-- jQuery -->
<script>
  $(document).ready(function(){
    $("#btn").click(function(){
      $("#msg").text("Hello, jQuery!");
    });
  });
</script>
