如何在数据表中使用该行的按钮添加类行？

Question

I'm using datatable jquery and I'v defined button in rows. I want to click button in any row. The row with button click will add class selected . If I choose another row , the row after will remove class selected , the new row click will add class selected .

 var table = $('#id_table').DataTable({ ////...... }); $('#id_table tbody').on('click', 'button', function (e) { table.row($(this)).hasClass('selected'); }); 

I get error as Uncaught TypeError: table.row(...).hasClass is not a function

I think you can use the following instead of using table.row($(this)).hasClass('selected'); here this is the button element.

$('#id_table tbody').on('click', 'button', function (e) {
  table.$('tr.selected').removeClass('selected');
  $(this).closest('tr').addClass('selected');
});

 $(document).ready(function() { var table = $('#id_table').DataTable(); $('#id_table tbody').on('click', 'tr', function() { table.$('tr.selected').removeClass('selected'); $(this).addClass('selected'); }); });
