How to remove default button class dataTables buttons?

Question

I am using a data table with Button. I want to show the Success button, not the default. I tried this code

buttons: [
{
extend: "excel",
className: "btn-sm btn-success",
titleAttr: 'Export in Excel',
text: 'Excel'
}]

This code works, but it adds the btn-success class, but first I want to remove the btn-default class, and then add the success class.

Current classes: "btn btn-default buttons-excel buttons-html5 btn-sm btn-success"

What I want: "btn buttons-excel buttons-html5 btn-sm btn-success"

Answer 1

Yes, it can be very annoying. .dt-buttonthe same without using bootstrap, where it is always added .dt-buttoneven if you declare className. There is a callback you can use to change, for example, classes: init

$('#example').DataTable( {
  dom: 'Bfrtip',
  buttons: [{
    extend: "excel",
    className: "btn-sm btn-success",
    titleAttr: 'Export in Excel',
    text: 'Excel',
    init: function(api, node, config) {
       $(node).removeClass('btn-default')
    }
  }]
});

$('button').click(function(){
	$(this).removeClass('btn-default');
  console.log($(this).attr('class'));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="btn btn-default buttons-excel buttons-html5 btn-sm btn-success" type="submit">
Submit
</button>

Answer 4

Changing the default class for all buttons in Datatable (updated fiddle )

$.fn.dataTable.Buttons.defaults.dom.button.className = 'btn'; //'btn btn-primary'

Answer 5

Maybe this will help

$('.dt-button').attr("class","btn-success");

Add this to jquery after loading datatables

Or you can create your own css class and mark require attributes as important for overriding the default style

Answer 6

Use this code to hide Excel text on a button:

 extend: 'excel',

 text: '',

 className: "btn btn-info btn-sm  glyphicon glyphicon-list-alt",
