Resolving ‘uncaught Typeerror: $(…).modal Is Not A Function’ In Bootstrap

Resolving “Uncaught TypeError: $(…).modal Is Not a Function” in Bootstrap


The error “Uncaught TypeError: $(…).modal Is Not a Function” typically arises when trying to use the Bootstrap modal plugin without properly including its JavaScript and jQuery dependencies. To resolve this error, follow these steps:


  1. Include jQuery: Ensure that jQuery is included on the page before loading Bootstrap JavaScript. This can be done by adding the following line to the section of your HTML document:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
  1. Include Bootstrap JavaScript: Include the Bootstrap JavaScript file, which contains the modal plugin, after including jQuery. The standard location for this file is:
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
  1. Check Initialization: Ensure that the modal is properly initialized using the $('#myModal').modal('show') syntax. The modal ID and the show method should be used correctly.


  2. Check Element Existence: Verify that the element with the specified ID, which is associated with the modal, exists in the DOM. The modal plugin requires a target element to operate upon.

  3. Check Dependencies: Confirm that there are no other JavaScript errors or conflicts on the page. These can prevent Bootstrap JavaScript from functioning correctly.

  4. Clear Cache: Sometimes, cached JavaScript files can cause this error. Try clearing your browser’s cache and reloading the page.

If these steps do not resolve the issue, consider inspecting the console for any additional error messages that may provide more context.
