如何更改“數據表”打印按鈕的默認CSS？

Question

我如何更改datatable插件中的print和excel按鈕的css。

                    $('#order_table').DataTable({
                        dom: 'Brtip',
                        buttons: [
                             'print','excel'
                        ]
                    });
                });

Answer 1

每個按鈕都有一個獨特的基類.buttons-print ， .buttons-excel ， .buttons-copy等。因此，您可以直接使用CSS設置按鈕的樣式

.buttons-print {
  background-color: red;
  color: white;
}
.buttons-excel {
  background-color: blue;
  color: white;
}

將.btn-default替換為.btn-primary ：

$('.buttons-excel, .buttons-print').each(function() {
   $(this).removeClass('btn-default').addClass('btn-primary')
})

   var orderDataTable =  $('#order_table').DataTable({
                        dom: 'Brtip',
                        buttons: [
                             'print','excel'
                        ]
                    });



     var tableTools_obj = new $.fn.dataTable.TableTools(orderDataTable , {
                    "sSwfPath": "swf/copy_csv_xls_pdf.swf",
                    "aButtons": [                           
                            {
                                "sExtends": "xls",
                                "sTitle": "OrdersReport",
                                "sToolTip": "Export to Excel",
                                "sButtonClass": "btn btn-transparent btn-primary btn-toolbar", // Here you can give all the classes realated to button with custom styles.
                                "sButtonText": "<i title='Export To Excel' class='ace-icon fa fa-file-excel-o white icon-tooltip'></i>", //overriding the default icon of Datatables, Here I am using Fontawsome icons
                               // "mColumns": GetExportableColumnsIndexes(); //this is to filter out hidden or unwanted columns form being exported.
                              // Usually it requires array on indexes, I prefer to call a function with some logic handling and returning the  required indexes.
                            }
                        ]
                    });

為此，您必須添加數據表的TableTools插件。 http://www.datatables.net/release-datatables/extensions/TableTools/js/dataTables.tableTools.js
