如何在重新加载页面后激活复选框？

Question

1）我选择了正确的复选框
2）按下＆＃34;申请＆＃34;按钮
3）重新加载页面 4）保留活动复选框，但名称是＆＃34;标签＆＃34;没有在单独的块中呈现
5）如果我点击任何复选框，则所有复选框都处于活动状态

将复选框呈现给所有活动标签并在#unit处呈现它们。我明白了，

var checkboxes = $('input[type=checkbox]:checked');

但显示无法

请帮忙，谢谢

$(document).ready(function() {
  checkbox = $('.ctf--b-filt-check-list :checkbox').on('change', function() {
    $('#unit').empty();
    var count = 0;
    $('.ctf--b-filt-c-item').map(function(i, el) {
      let unit = $(this).find('input:checked').map(function(i, el) {
        return ('<div class="ctf-b-btn-filter-items">' + $('[for="' + el.id + '"]').text() + '</div>');
      }).get();
      if (unit.length > 0) {
        count += unit.length;
        $('#unit').append('<div class="father father_tmp">' + $(this).find('.b-txt').text() + '</div>');
        $('#unit').find('.father_tmp').append(unit.join(''));
        $('.father_tmp').removeClass('father_tmp');
      }
    });
  });

});

.ctf-b-btn-filter-items {
