Question

我正在使用数据表jquery和我在行中定义的按钮。我想点击任意一行的按钮。单击按钮的行将添加类selected。如果我选择另一行，则后面的行将删除类selected，新行单击将添加类selected。

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

我收到错误Uncaught TypeError: table.row(...).hasClass is not a function

Answer 1

我认为你可以使用以下代替table.row($(this)).hasClass('selected');这里this是按钮元素。

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

＆＃13;

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