If you’ve ever encountered the error message “Uncaught ReferenceError $ is not defined” while working on a web development project, you know how frustrating it can be. This error is typically caused by an issue with the jQuery library, which is a popular JavaScript library used for simplifying web development.

Why does the error ‘Uncaught referenceerror $ is not defined’ happen?

The “Uncaught ReferenceError: $ is not defined” error occurs when JavaScript code tries to use the $ shortcut to access the jQuery library, but the browser is unable to find the jQuery library. There are several reasons why this might happen:

  • jQuery is not properly included in the project: If the jQuery library is not included in the project, the browser will not be able to find it when the JavaScript code tries to access it.
  • The script tag for jQuery is not in the correct order: If the script tag for jQuery is loaded after other scripts that depend on it, the browser will not be able to find the jQuery library when those scripts try to use it.
  • There is a conflict with other JavaScript libraries: If multiple JavaScript libraries are used in the project, they may conflict with each other and cause issues with the $ shortcut.
  • The version of jQuery being used is causing the error: Sometimes, certain versions of jQuery can cause issues with the $ shortcut. In this case, using a different version of jQuery may be necessary to resolve the issue.

How to fix the error ‘Uncaught referenceerror $ is not defined’?

You can address this issue by incorporating jQuery.js before including the relevant jQuery plugins. Let’s take a look at the following instance:

<script src=”/lib/jquery.min.js”></script>
<script src=”/lib/jquery.plugin.js”></script>

Besides, if the path to the jQuery library is incorrect, browsers may be unable to load the jQuery file, which could be due to a typo or the movement of the file to a different location. To resolve this issue, it’s essential for you to rectify the path.

The ultimate remedy to this issue is to verify your Internet connection is functioning correctly. Additionally, you can incorporate a local version of the jQuery library. For example:

<script src=”/js/jquery.min.js”></script>
