datatable: show row per page and export button at the same time

Well this posting is an extra info of my previous posting. After I struggled with an error, now I want to show the page per button and the export button at the same time. 

I found two ways from stackoverflow. 

so here is the first solution:

$(document).ready(function() {
    document.title = 'page Title';
    $('#example').DataTable( {
        dom: 'Bfrtip',
        lengthMenu: [[10, 25, 50, -1], [10, 25, 50, "All"]],
        buttons: [
            'pageLength',
            'copyHtml5',
            'excelHtml5',
            'csvHtml5',
            'pdfHtml5'
        ],
    } );
} );

You can delete or comment the second line, it was included in my code since I coded it in a team and the used template seems doesn't have title tag in its header. So, I set it in here. The title of the page will be used as the filename when its downloaded. 

The second solution is:

$(document).ready(function() {
    document.title = 'page Title';
    $('#example').DataTable( {
        dom: 'lBfrtip',
        lengthMenu: [[10, 25, 50, -1], [10, 25, 50, "All"]],
        buttons: [
            'copyHtml5',
            'excelHtml5',
            'csvHtml5',
            'pdfHtml5'
        ],
    } );
} );

Take a look at the 'dom:' attribute. The second solution uses 'lBftrip' whereas the first solution uses 'Bfstrip'. now then take a look closer to the first solution, if we use 'Bfstrip', then we have to add 'pagelength' as a button as well. 

Just try them and see the different. NOTE!!! don't forget to call all the needed css and js scripts. You can find them all here.

Datatable Error : Uncaught TypeError: $(...).DataTable is not a function

 It was really pain in the ass to look for a solution for that error. But, finally I found it.

Here is the solution: Use defer to call the datatable script and its other following scripts. 

I needed to use datatable with export button, I get the examples code from here.

Here was how I called the scripts that gave me that error:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js" ></script>
<script type="text/javascript"  src="https://cdn.datatables.net/1.11.3/js/jquery.dataTables.min.js" ></script>
<script type="text/javascript"  src="https://cdn.datatables.net/buttons/2.1.0/js/dataTables.buttons.min.js" ></script>
<script type="text/javascript"  src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.3/jszip.min.js" ></script>
<script type="text/javascript"  src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/pdfmake.min.js" ></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/vfs_fonts.js" ></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.1.0/js/buttons.html5.min.js" ></script>

And how it was fixed:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js" ></script>
<script type="text/javascript"  src="https://cdn.datatables.net/1.11.3/js/jquery.dataTables.min.js" defer></script>
<script type="text/javascript"  src="https://cdn.datatables.net/buttons/2.1.0/js/dataTables.buttons.min.js" defer></script>
<script type="text/javascript"  src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.3/jszip.min.js" defer></script>
<script type="text/javascript"  src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/pdfmake.min.js" defer></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/vfs_fonts.js" defer></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.1.0/js/buttons.html5.min.js" defer></script>

I found the solution in this forum and here is the link that explains how defer works.
