单击复选框不会显示组标记，但会显示所有标记和所有组。当我搜索“T^T”时，它需要很长时间。

这是复选框

<p>
    <label>
    <input type="checkbox" id="01"  onclick="toggleGroup('01')"CHECKED/>
    </label>
  01 
  <label>
  <input type="checkbox" id="02"  onclick="toggleGroup('02')" CHECKED/>
  </label>
  02 
  <label>
  <input type="checkbox" id="03"  onclick="toggleGroup('03')" CHECKED/>
  </label>
  03 
  <label>
  <input type="checkbox" id="04" onclick="toggleGroup('04')" CHECKED/>
  </label>
  04</p>

它显示所有标记，但如果单击“复选框”，它不会按组显示标记。
