Text Editor or IDE

  • Notepad: A basic text editor, suitable for simple projects.
  • Visual Studio Code: A popular, free, open-source code editor with extensive features and extensions.
  • Sublime Text: A powerful text editor known for its speed and customization options.
  • WebStorm: A robust IDE specifically designed for web development, offering advanced features like debugging and code completion.

jQuery Library

Download

Obtain the jQuery library from the official jQuery website: https://jquery.com/. Choose between the compressed (.min.js) or uncompressed version based on your needs.

Include in Your HTML

There are two main ways to include jQuery in your HTML: using a local path or a CDN.

Local Path

Place the downloaded jQuery file in your project directory and reference it using a <script> tag:

<script src="path/to/jquery.js"></script>

CDN (Content Delivery Network)

Use a CDN to load jQuery from a remote server:

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

Fallback

For reliability, consider using a fallback mechanism to load jQuery from your local server if the CDN is unavailable:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  window.jQuery || document.write('<script src="path/to/local/jquery.js"></script>');
</script>

Example: Reference jQuery in an HTML Page

<!DOCTYPE html>
<html>
<head>
    <script src="~/Scripts/jquery-3.3.1.js"></script>   
</head>
<body>
</body>
</html>

Include jQuery Library from CDN

You can also reference the jQuery library from a public CDN such as Google, Microsoft, CDNJS, or jsDelivr.

<!DOCTYPE html>
<html>
<head>
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"
        integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
        crossorigin="anonymous">
    </script>
</head>
<body>
</body>
</html>

Example: Use CDN with Fallback

<!DOCTYPE html>
<html>
<head>
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"
        integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
        crossorigin="anonymous">
    </script>
    <script>
    // Fallback to loading jQuery from a local path if the CDN is unavailable
    (window.jQuery || document.write('<script src="~/scripts/jquery-3.3.1.min.js"></script>'));
    </script>
</head>
<body>
</body>
</html>

jQuery API Documentation

jQuery provides online API documentation. Click on "API Documentation" on jquery.com or go to api.jquery.com. The documentation page lists jQuery features on the left side, with related functions on the right. Click on a function to get detailed information with examples.

Key Considerations

  • IntelliSense: Choose an editor that supports IntelliSense for JavaScript and jQuery to enhance code completion and error checking.
  • Compressed vs. Uncompressed: Use the compressed version for production to minimize file size, and the uncompressed version for development for easier debugging.
  • CDN vs. Local: CDNs can improve performance by serving jQuery from multiple locations, but using a local copy ensures availability.
  • Fallback Mechanism: Implementing a fallback ensures that your website functions even if the CDN is inaccessible.

By following these steps and considering the recommended practices, you'll have a solid foundation for developing with jQuery.
