Institution:375 Uncaught ReferenceError: $ is not defined

The error message "Uncaught ReferenceError: $ is not defined" typically occurs in ABAP when the jQuery library is not properly loaded or referenced in your code. To resolve this issue, you need to ensure that jQuery is included and accessible in your ABAP program. Here are a few steps you can follow to fix this error:

  1. Make sure jQuery is included: Check if the jQuery library is included in your project. You can either download the jQuery file and include it in your project directory or use a Content Delivery Network (CDN) to reference the jQuery library directly in your code.

  2. Check the script tag: If you are using a local jQuery file, make sure you have included the correct path to the file in the script tag. For example:

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

If you are using a CDN, make sure the URL in the script tag is correct. For example:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
  1. Check the order of script tags: If you have multiple script tags in your code, ensure that the jQuery script tag is placed before any other scripts that depend on it. This ensures that jQuery is loaded and available before other scripts start executing.

  2. Check for conflicts: If you are using other JavaScript libraries or frameworks that also use the $ symbol as a shorthand for their own functions, it can cause conflicts with jQuery. In such cases, you can use the jQuery keyword instead of $ to avoid conflicts. For example:

jQuery(document).ready(function() {
  // Your code here
});

By following these steps, you should be able to resolve the "Uncaught ReferenceError: $ is not defined" error in ABAP when working with jQuery.
