Question

I have a bunch of checkboxes, that I’d really like to make the user only able to select upto 5. Once selected 5, then the others are then disabled.

The HTML markup is:

<ul class="options-list">
 <li>
   <input type="checkbox" value="259" name="bundle_option[9][]" id="bundle-option-9-259" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-259">1 x Test 1</label></span>
</li>
 <li>
   <input type="checkbox" value="260" name="bundle_option[9][]" id="bundle-option-9-260" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-260">1 x Test 1</label></span>
</li>
 <li>
   <input type="checkbox" value="261" name="bundle_option[9][]" id="bundle-option-9-261" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-261">1 x Test 1</label></span>
</li>
 <li>
   <input type="checkbox" value="262" name="bundle_option[9][]" id="bundle-option-9-262" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-262">1 x Test 1</label></span>
</li>
 <li>
   <input type="checkbox" value="263" name="bundle_option[9][]" id="bundle-option-9-263" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-263">1 x Test 1</label></span>
</li>
 <li>
   <input type="checkbox" value="264" name="bundle_option[9][]" id="bundle-option-9-264" class="change-container-classname checkbox bundle-option-9">
   <span class="label"><label for="bundle-option-9-264">1 x Test 1</label></span>
</li>
</ul>

My main problem is targeting the checkboxes.

Can I target them using the name value of bundle_option[9][]?

Thanks

Yes you can, but because you have [ and ]‘s in the name (which have a special meaning in jQuery selectors), you have to escape them with \\; (taken from API docs);

If you wish to use any of the meta-characters ( such as !”#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, you must escape the character with two backslashes: \.

$(':checkbox[name="bundle_option\\[9\\]\\[\\]"]');
