我已经开始学习JS和jQuery,并且在一个我无法解决的挑战中发现了一个障碍。我对这个相当陌生,所以解释一下会很有帮助。
Fiddle展示了我所取得的成就:(它可以工作,但不像预期的那样):Fiddle

var filters1 = {
  "A": {
    "active": true
  },
  "B": {
    "active": true
  },
};

var filters2 = {
  "1": {
    "active": true
  },
  "2": {
    "active": true
  },
};

$(document).on('click', '.tag-filter', function() {
  var id = $(this).attr('id');
  if (id in filters1) {
    if (filters1[id].active) {
      filters1[id].active = false;
      $('.' + id).css("display", "none");
      $(this).addClass("active-tag-filter");
    } else {
      filters1[id].active = true;
      $('.' + id).css("display", "inline-block");
      $(this).removeClass("active-tag-filter");
    }
  } else if (id in filters2) {
    if (filters2[id].active) {
      filters2[id].active = false;
      $('.' + id).css("display", "none");
      $(this).addClass("active-tag-filter");
    } else {
      filters2[id].active = true;
      $('.' + id).css("display", "inline-block");
      $(this).removeClass("active-tag-filter");
    }
  }
});
.tag {
  display: inline-block;
  background-color: black;
  color: white;
  margin: 4px;
  text-align: center;
  min-width: 32px;
  min-height: 32px;
}

.tag-filter {
  display: inline-block;
  background-color: red;
  color: black;
  margin: 4px;
  text-align: center;
  min-width: 32px;
  min-height: 32px;
}

.active-tag-filter {
  background-color: green;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
  <div class='tag-filter' id='A'>A</div>
  <div class='tag-filter' id='B'>B</div>
  <div class='tag-filter' id='1'>1</div>
  <div class='tag-filter' id='2'>2</div>
</div>
<br>
<div>
  <div class='tag A 1'>A1</div>
  <div class='tag A 2'>A2</div>
  <div class='tag B 1'>B1</div>
  <div class='tag B 2'>B2</div>
</div>
我想要实现的目标:

好榜样胜过千篇作品;我想要一个像这样的过滤器:点击几下,你就会明白我的意思。
如果有更好的解释:
1.当激活第一组(字母)的标签过滤器时,仅显示带有该字母的标签。例如,当单击标签过滤器A时,仅显示标签A1和A2。
1.当来自同一组的另一个标签过滤器被激活时,结果是求和。例如,当点击标签过滤器A,然后点击B时,显示标签A1、A2、B1、B2。
1.当用户从两组中选择标签过滤器时,依次单击A〉B〉1。例如,应显示A1,A2〉显示A1,A2,B1,B2〉显示A1和B1。
如果有人想为我写代码那就太好了,但更重要的是,这是一个好的方法吗?有没有更好的方法来进行这样的过滤?
先谢了!

OP在这里.一个评论者建议一个数组,我使用,除了hide()和show()方法,我知道.缺少的组件是join()和filter()方法,这对我来说是新的.这对我来说是很好的学习经验,感谢帮助.
最后,这里是工作小提琴,过滤工作,因为我的意图。Fiddle

$(document).ready(function() {
  $(".filter-btn").click(function() {
    var filterValue = $(this).attr("data-filter");
    
    if ($(this).hasClass("active")) 
    {
      $(this).removeClass("active");
    } 
    else 
    {
      $(this).addClass("active");
    }
    
    var activeFilters1 = [];
    var activeFilters2 = [];
    $("#filter-container1 .filter-btn.active").each(function() {
      activeFilters1.push($(this).attr("data-filter"));
    });
    $("#filter-container2 .filter-btn.active").each(function() {
      activeFilters2.push($(this).attr("data-filter"));
    });
    
    if (activeFilters1.length === 0 && activeFilters2.length === 0) {
      // Show all items if no filters are active
      $(".item").show();
    } else if (activeFilters1.length > 0 && activeFilters2.length === 0) {
      // Show only items that match any of the active filters in the first group
      $(".item").hide().filter("." + activeFilters1.join(",.")).show();
    } else if (activeFilters1.length === 0 && activeFilters2.length > 0) {
      // Show only items that match any of the active filters in the second group
      $(".item").hide().filter("." + activeFilters2.join(",.")).show();      
    } else {
      // Show all items that match any of the active filters in the first group
      // Then refine the selection to only those that also match the active filters in the second group
      $(".item").hide().filter("." + activeFilters1.join(",.")).filter("." + activeFilters2.join(".")).show();
    }
  });
});
.item {
  display: block;
}

.active {
  background-color: #555;
  color: white;
}
