Why Isn\'t My $(...).DataTable() Function Working in jQuery?

jQuery DataTables' $(...).DataTable is not a function

Background

jQuery's DataTables is a popular library for enhancing the functionality of HTML tables. Developers encountering the error "TypeError: $(...).DataTable is not a function" may experience issues incorporating it into their applications.

Cause

This error typically occurs due to an incorrect or missing dependency. DataTables relies on jQuery, and if jQuery is not included correctly, the DataTables function will not be available.

Solution

To resolve this issue, it is crucial to include the jQuery library and ensure it is loaded before the DataTables library. Here's a breakdown of the solution:

1. Confirm jQuery Inclusion: Ensure that the jQuery library is included in your project and placed before the DataTables library. Verify that you're using a compatible version of jQuery (recommendation: 1.7 or newer).
2. Correct Inclusion Order: The order in which you include the scripts matters. jQuery must be included before DataTables.

For example:

<script src="js/jquery.min.js" type="text/javascript"></script>
<script src="js/jquery.dataTables.min.js" type="text/javascript"></script>

3. Avoid Multiple jQuery Versions: If multiple versions of jQuery are included on the page, conflicts can arise. Use only one compatible version of jQuery.

By implementing these steps, you can ensure the proper loading of jQuery and DataTables, eliminating the "TypeError: $(...).DataTable is not a function" error.
