只允许使用 jQuery 检查同一 div 中的复选框

Question

I have 3 Divs, every div contains 2 inputs, I want to only check checkboxes in the same div with id and unchecked from other divs.

HTML is :

<div class="dashboard">

 <div id="fr">
  <h3>Fruits</h3>
  <label>
   <input type="checkbox" name="check1" />Kiwi</label>
  <label>
   <input type="checkbox" name="check2" />Jackfruit</label>
 </div>

 <div id="an">
  <h3>Animals</h3>
  <label>
   <input type="checkbox" name="check1" />Tiger</label>
  <label>
   <input type="checkbox" name="check2" />Sloth</label>
 </div>

 <div id="veg">
  <h3>vegetables</h3>
  <label>
   <input type="checkbox" name="check1" />Tiger</label>
  <label>
   <input type="checkbox" name="check2" />Sloth</label>
 </div>

</div>

and JQuery is :

$("input:checkbox").on('click', function() {
 var $box = $(this);
 if ($box.is(":checked")) {
  var group = "input:checkbox[name='" + $box.attr("name") + "']";
  $(group).prop("checked", false);
  $box.prop("checked", true);
 } else {
 $box.prop("checked", false);
 }
});

If you only want to allow checkboxes to be checked within a single div , you can use jQuery to traverse the DOM using closest() , siblings() and find() to retrieve the external checkboxes before de-selecting them.

Try this:

 $("input:checkbox").on('change', e => { $(e.target).closest('div').siblings().find('input:checkbox').prop('checked', false); });
