How can I remove default button class of a dataTables button?

Question

I am using Data table with Button. I want to show Success button rather default. I tried this Code

buttons: [
{
extend: \"excel\",
className: \"btn-sm btn-su         


        

Answer 1

Maybe this can help

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

Add this to jquery after loading Datatables

Or you can make your own css class and mark the require attributes as !important to override the default style

Answer 2

Yes, this can be really annoying. It is the same without using bootstrap, where .dt-button always is added even if you declare className. There is a init callback you can use to modify for example classes :

$('#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')
    }
  }]
});

Update: Have received a lot of upvotes on this, but the correct or best answer is actually "DavidDomains"'s answer below. Use

buttons: {
  dom: {
    button: {
      className: ''
    }
  },
  buttons: [{
    //here comes your button definitions
  }]
}

Answer 3

You should take a look at the buttons.dom.button option.

buttons.dom.button

This option controls the HTML tag that is used to create each individual button. With this option the tag type and class name can be specified using the tag and className properties of this object.

This will give you total control on how the button will be rendered in the DOM. No need to remove any classes afterwards.

Here is an example.

$('#example').DataTable( {
  dom: 'Bfrtip',
  buttons: {
    dom: {
      button: {
        tag: 'button',
        className: ''
      }
    },
    buttons: [{
      extend: 'excel',
      className: 'btn btn-sm btn-success',
      titleAttr: 'Excel export.',
      text: 'Excel',
      filename: 'excel-export',
      extension: '.xlsx'
    }, {
      extend: 'copy',
      className: 'btn btn-sm btn-primary',
      titleAttr: 'Copy table data.',
      text: 'Copy'
    }]
  }
});

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

Use this code to hide Excel text on button:

 extend: 'excel',

 text: '',

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