You don’t know how and why it occurs and don’t know how to fix it? Worry no more! and read this entire article.

In this article, we will discuss the possible causes of “Uncaught typeerror datatable is not a function”, and provide solutions to resolve the error.

But first, Let’s Discuss what this Typeerror means.

What is Uncaught typeerror datatable is not a function?

This error message Uncaught typeerror datatable is not a function means that the code is trying to use a function called “datatable”, but for some reason, the function is not defined or accessible.

This error often occurs when the required JavaScript library or plugin is not loaded or initialized correctly.

Now let’s move to the causes of this Typeerror.

Causes of Uncaught typeerror datatable is not a function

“Uncaught TypeError: datatable is not a function” error occurs in JavaScript when the code attempts to use a function called “datatable” that is not defined or accessible.

Here are some reasons why datatable is not a function occurs along with example codes:

1. DataTables library not included.

If the DataTables library is not included in the HTML file, the error can occur when the code tries to call the DataTable function.

For example:

<!-- DataTables library not included -->
<script>
  $(document).ready(function(){
    $('#myTable').DataTable();
  });
</script>

In this example code snippet, we are attempting to use the DataTables plugin on a webpage in this code snippet, but the DataTables library is not included in the HTML file.

2. DataTables library loaded before the jQuery library

If the DataTables library is loaded before the jQuery library, the DataTable function may not be recognized.

For example

<!-- DataTables library loaded before jQuery library -->
<script src="https://cdn.datatables.net/1.10.25/js/jquery.dataTables.min.js"></script>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function(){
    $('#myTable').DataTable();
  });
</script>

This example attempts to use the DataTables plugin on a webpage, but the DataTables library is loaded before the jQuery library.

Since the DataTables library depends on jQuery, it must be loaded after the jQuery library.

3. jQuery library loaded twice:

If the jQuery library is loaded multiple times in the same HTML file, it can cause conflicts and prevent the DataTable function from being recognized.

Here is an example code:

<!-- jQuery library loaded twice -->
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://cdn.datatables.net/1.10.25/js/jquery.dataTables.min.js"></script>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function(){
    $('#myTable').DataTable();
  });
</script>

This code snippet attempts to use the DataTables plugin on a webpage, but the jQuery library is loaded twice.

Loading the jQuery library multiple times can cause conflicts and result in errors like “datatable is not a function”.

4. Incorrect path to the jQuery files:

If the path to the jQuery files is incorrect, the jQuery library may not be loaded correctly, causing the DataTable function to fail.

Just the example code below:

<!-- Incorrect path to the jQuery files -->
<script src="js/jquery-3.6.0.min.js"></script>
<script src="https://cdn.datatables.net/1.10.25/js/jquery.dataTables.min.js"></script>
<script>
  $(document).ready(function(){
    $('#myTable').DataTable();
  });
</script>

In this example, we attempt to use the DataTables plugin on a webpage, but the path to the jQuery library is incorrect.

Now let’s fix these errors.
