DataTables: Uncaught TypeError: Cannot read property 'defaults' of undefined

When using the Bootstrap integration for DataTables, I see the following error in the console:

Uncaught TypeError: Cannot read property 'defaults' of undefined (dataTables.bootstrap.js:20)

This causes the pagination controls to not have styles on them.

I can see that in the factory initialization, the following code needs to run:

factory( jQuery, jQuery.fn.dataTable );

However, jQuery.fn.dataTable is returning undefined.

The problem is that dataTable is not defined at the point you are calling this method.

Ensure that you are loading the .js files in the correct order:

<script src="/Scripts/jquery.dataTables.js"></script>
<script src="/Scripts/dataTables.bootstrap.js"></script>

I got the same error, I'm using laravel 5.4 with webpack, here package.json before:

{
  ...
  ...
  "devDependencies": {
    "jquery": "^1.12.4",
    ...
    ...
  },
  "dependencies": {
    "datatables.net": "^2.1.1",
    ...
    ...
  }
}

I had to move jquery and datatables.net npm packages under one of these "dependencies": {} or "devDependencies": {} in package.json and the error disappeared, after:

{
  ...
  ...
  "devDependencies": {
    "jquery": "^1.12.4",
    "datatables.net": "^2.1.1",
    ...
    ...
  }
}

I hope that helps!

<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>

Add Defer to the end of your Script tag, it worked for me (;

Everything needs to be loaded in the correct order (:

var datatable_jquery_script = document.createElement("script");
datatable_jquery_script.src = "vendor/datatables/jquery.dataTables.min.js";
document.body.appendChild(datatable_jquery_script);
setTimeout(function(){
    var datatable_bootstrap_script = document.createElement("script");
    datatable_bootstrap_script.src = "vendor/datatables/dataTables.bootstrap4.min.js";
    document.body.appendChild(datatable_bootstrap_script);
},100);

I used setTimeOut to make sure datatables.min.js loads first. I inspected the waterfall loading of each, bootstrap4.min.js always loads first.
