The example in this article describes how JQuery limits the number of checkboxes that can be selected. Share it with everyone for your reference. The specific analysis is as follows:

Since the project needs to limit the number of files that can be operated in batches, I wrote a small code
If the number of selected items is greater than the maximum allowed number, other check boxes cannot be selected
If less than then all checkboxes can be selected

<script type="text/javascript">
 $(document).ready(function() {
  $('input[type=checkbox]').click(function() {
   $("input[name='apk[]']").attr('disabled', true);
   if ($("input[name='apk[]']:checked").length >= 3) {
    $("input[name='apk[]']:checked").attr('disabled', false);
   } else {
    $("input[name='apk[]']").attr('disabled', false);
   }
  });
 })
</script>
<ul>
 <li>
  <input type="checkbox" name="apk[]" value=1 />
  APK1
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=2 />
  APK2
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=1 />
  APK3
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=4 />
  APK4
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=6 />
  APK5
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=7 />
  APK6
 </li>
 <li>
  <input type="checkbox" name="apk[]" value=8 />
  APK7
 </li>
</ul>

I hope this article will be helpful to everyone’s jQuery programming.
