我以 Mamun 的答案作为参考,用回了我喜欢的图标。 (刚刚意识到 Mamun 已经删除了他原来的答案,因为他使用的是 font Awesome 而不是 glyphicon。无论如何,非常感谢你给我这些想法!)

function toggledDeleteAllBtn() {
  if ($('.customer_checkbox:checked').length > 0) {
    $('#sel_button').html('<i class="glyphicon glyphicon-trash" </i>Delete all selected(' + $('.customer_checkbox:checked').length + ')');
  } else {
    $('#sel_button').html('<i class="glyphicon glyphicon-trash" </i>Delete all selected');
  }
}
$(document).on('click', '.customer_checkbox', toggledDeleteAllBtn);
