Uncheck parent node if all children unchecked in JQuery -


i want uncheck parent node if children unchecked.

<ul id="treelist">    <li>    <input type="checkbox" name="selectedrole">    application manager     <ul>        <li>            <input type="checkbox" name="selectedrole">            application manager panel        </li>        <li>             <input type="checkbox" name="selectedrole">             client role              <ul>                <li>                    <input type="checkbox" name="selectedrole">                    client task 1                 </li>                 <li>                    <input type="checkbox" name="selectedrole">                     client task 2                 </li>                  </ul>               </li>            </ul>        </li>

i have following jquery script. when uncheck children, parent got uncheck. should see, if children unchecked. should uncheck parent. 

jquery.each(jquery('#treelist ul li').find(':checkbox'),  function(){     jquery(this).change(function (){         if (jquery(this).is(':checked')) {             jquery(this).parents('ul').siblings('input:checkbox').attr('checked', true);         }else{             jquery(this).parents('ul').siblings('input:checkbox').attr('checked', false);         }             });     });

you unchecking parent li checkbox every time uncheck child, instead of checking if there's still other checked items. instead, check number of items checked , use length boolean:

jquery.each(jquery('#treelist ul li').find(':checkbox'),  function(){     jquery(this).change(function (){         if (jquery(this).is(':checked')) {                       jquery(this).parentsuntil('#treelist').siblings().filter('input:checkbox').attr('checked', true).trigger('change');         }else{                             jquery(this).parents('ul:first').siblings('input:checkbox').prop('checked', $(this).parent().siblings().children('input:checked').length).trigger('change');         }             });     });
