jQuery is not defined

The error "jQuery is not defined" typically occurs when you are trying to use jQuery code without including the jQuery library in your web page. To fix this error, you need to make sure that you include the jQuery library correctly.

You can include the jQuery library by adding the following code in the head section of your HTML file:

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

Make sure that this script tag is placed before any other JavaScript code that depends on jQuery. By including this script, you will have access to the jQuery library and the "jQuery is not defined" error should be resolved.

If you are already including the jQuery library and still encountering this error, there might be an issue with the file path or version of the jQuery library you are using. Double-check the file path and ensure that it is correct. Also, consider updating to the latest version of jQuery if you are using an older version.

If you continue to experience issues, please provide more details about your specific scenario so that I can assist you further.
